  • How lightning can help your garden grow

    [ad_1]

    The classic summer thunderstorm is doing more for your lawn and garden than you might realize. That extra bit of green and growth after a storm isn’t just because it rained.

    There is a science behind why that is the case, and I’m here to explain it. 

    What You Need To Know

    • Lightning plays a big role in the nitrogen cycle

    • Nitrates are considered a “super fertilizer” that helps plants green up faster

    • Most plants receive usable nitrogen through bacteria in soil


    Understanding what the nitrogen cycle does is important to know before diving into lightning’s role in the cycle. Simply put, plants need nutrients to grow. 

    About 78% of Earth’s atmosphere is made up of “free” nitrogen (N2) gas. All living things need nitrogen to build amino acids, essential proteins, as well as DNA and RNA. 

    Nitrogen in its “free” form cannot be used by living things. That is where the nitrogen cycle comes in. For nitrogen to be used, it must be changed into different states like nitrates (NO3), nitrites (NO2), and ammonium (NH3). 

    Nitrogen is mostly brought into the living world by way of bacteria in the soil, which convert atmospheric nitrogen into the nitrates. Once in any of those usable states, plants can take up these molecules and grow. 

    Lightning’s role in the nitrogen cycle

    While most of the free nitrogen is converted through bacteria, lightning also plays a meaningful role. 

    During a storm, the explosive heat of lightning tears the nitrogen and oxygen molecules in the air apart. The free molecules then recombine, forming nitrogen oxides, which fall down to earth in the rain. 

    Given that most rain doesn’t carry many nutrients, nitrogen oxide-filled raindrops can bring abundant free fertilizer to your yard and garden during a storm. A storm or two may not make a big difference, but multiple rounds of storms over the course of a week or two can bring lush green and vivid colors to your garden.

    So when you hear cracks of thunder outside, just know that your plants are thankful!

  • The Perseid meteor shower begins, lasts through late August

    [ad_1]

    The Perseid meteor shower is always a highly-anticipated astronomical event. However, this year, the viewing may be more difficult than in years past.

    What You Need To Know

    • The Perseid meteor shower has up to 75 meteors per hour

    • The best time for viewing will fall in the pre-dawn hours

    • A full moon may get in the way of peak viewing

    The Perseid meteor shower starts Thursday, July 17 and lasts through Aug. 24. While you can spot meteors zooming across the sky any time after dark, your best opportunity will be in the few hours before sunrise.

    As the night goes on, the constellation Perseus — where the meteors appear to originate­ — will rise higher in the northeast sky. However, you can look anywhere overhead, not just in that direction.

    Meteors will be visible through the duration of the event, but its peak is on Tuesday, Aug. 12. If you’re lucky enough to have a clear sky, you may see 50 to 75 meteors every hour. 

    The Perseids produce long, bright trails, making it one of the more visual annual showers.

    We see the Perseids in the late summer as the Earth passes through the dust and debris that Comet Swift-Tuttle leaves behind. The “shooting stars” actually come from grains that are about the size of Grape Nuts, according to Sky & Telescope, that burn in the atmosphere as they zip by at over 130,000 miles per hour.

    The nuggets of Grape Nuts cereal are a good approximation of the cometary dust grains that create meteor showers.

    There is one fly in the ointment for this year’s Perseid viewing. The next full moon on the morning of Saturday, Aug. 9, is expected to be one of the brightest of the year. This will severly limit the number of meteors seen in the day or two leading up to and following the full moon.

    This would closely coincide with the peak on Tuesday, Aug. 12. 

    No matter what, you’ve got plenty of time to see this premier celestial event for the next several weeks.

  • How the weather could impact tonight’s MLB Home Run Derby

    [ad_1]

    When you think of a baseball player hitting a home run, there are lots of variables that come into play. Who is the batter? Who is the pitcher? What stadium are they playing at? But what about the weather? 

    Wind, rain and snow may come to mind first, but temperature and humidity can influence how far a baseball travels and be a deciding factor in if the ball makes it out of the park.

    What You Need To Know

    • The temperature can influence how far a baseball travels

    • Warm and humid air is less dense than cold and dry air

    • Lower density allows the baseball to travel further

    Warm air is less dense than cold air. Air expands when it’s heated, so the molecules are more spread out. This means there is less air for the ball to travel through, giving it less resistance. 

    Now factoring in humidity, warmer air can hold more moisture. Water vapor is light compared to nitrogen and oxygen molecules, so humid air is less dense than dry air at the same temperature.

    When it’s hot and humid, the air is lighter, and the baseball can travel further.

    A 2023 study claims that “a 1° C increase in the daily high temperature on the day of a baseball game played in a stadium without a dome increases the number of home runs in that game by 1.96%.” A bigger difference in home runs was observed for games played during the early afternoon versus night games because of the larger difference in temperature.

    How about cold air? Cold air is more dense than warm air, so the ball has to travel through more air. Molecules move closer together when the air contracts as temperature lowers. 

    If it’s cold and dry out, the drier air will have fewer water vapor molecules, so the nitrogen and oxygen comprising the air will be heavier than the humid air would be. 

    Ideally, outdoor games in hot and humid climates are most favorable for seeing your favorite team or player hit a home run.

    Tonight’s MLB Home Run Derby is in Atlanta, and the forecast calls for no rain and temperatures near 90 degrees with heat index values in the mid-90s. Get ready to watch the ball fly!

  • 5 simple ways to run your A/C less this summer

    [ad_1]

    Help your air conditioner help you stay cool this summer. Check out these things that you can do today to take some pressure off your A/C and save you some money on your electric bill.

    What You Need To Know

    • Your ceiling fan should spin a certain way to create a breeze

    • Limit the amount of sunlight coming into your home

    • Raise the thermostat, especially when you’re away

    • Maintain your air conditioning system



    Look at your ceiling fans

    Turn on your ceiling fans and see which way they’re spinning. Having them go counterclockwise circulates the air around the room, creating a small breeze that’ll help keep you cool.

    This can especially become helpful if you have a second floor, since warm air rises and you might need a little extra “oomph” to keep things cool there.

    (Spectrum News/Justin Gehrts)

    Open up

    Don’t close doors to rooms or walk-in closets. Keeping them open lets air circulate. One exception to this rule is the bathroom while showering, beyond obviously wanting privacy. You don’t want your air conditioner working hard to counteract the warm, humid air, so close that door while you’re in there and turn on the ceiling vent fan.

    Block the sun

    Okay, you can’t completely blot out the sun’s light to keep it from heating up your house. But you can close your blinds or curtains. Bright sunlight shining through the windows adds unwanted heat… well, maybe not unwanted by everyone.

    Turn the dial

    Stop us if you’ve heard this one before: Turn up your thermostat a few degrees. There’s a good reason it’s repeated so often. Every degree of cooling increases energy usage by as much as 8%!

    (Photo by Olivia Levada)

    Try upping it by a degree or two at first and gradually increase it as you get more used to the higher setting. Remember to use fans to your advantage.

    If you’d rather not set your thermostat higher all the time, try doing it when you’re going to be away for a while. Just don’t crank it really low for your return; a colder setting doesn’t make your home cool any faster.

    Keep it clean

    Replace the indoor air filter as necessary (usually every couple of months), since a dirty filter reduces air flow and makes your A/C work harder than it needs to.

    (Spectrum News)

    You also need to keep the actual air conditioning unit that’s outdoors clean. Remove leaves and other debris, then hose off the dust, dirt and other stuff that’s gotten stuck in there.

    Extra credit

    Want to go above and beyond the five simple tips above? Here are three bonus ideas.

    • Seal air leaks around windows. Many kids have heard “we’re not cooling the outside!” as they hold the front door open for longer than necessary. Your house might already be doing that without being as obvious. Closing those leaks keeps warm air out and cool air in.
    • Get an A/C inspection. An ounce of prevention is worth a pound of cure. Having a professional check on your air conditioner each year can save you a lot of trouble… and sweating, if it conks out in the middle of the summer.
    • Plant shade trees. These are most effective on the south and west sides of your house, since that’s where the strongest afternoon sunshine comes from. This can be pricey up front, but is certainly beneficial. If you DIY it, be sure to get underground utilities marked.

  • The colorful chemistry behind firework displays

    [ad_1]

    On America’s first Fourth of July in 1777, there was one color – orange. Fireworks have come a long way since then, taking on new colors and various shapes and sizes.

    However, there is a lot of science behind these modern-day marvels.

    What You Need To Know

    • Fireworks are chemical reactions made of high energy compounds

    • The type of atom used in the firework mixture gives off certain colors when heated

    • Atmospheric conditions play a critical role in firework visibility

    How it works

    The colors that we see lighting up the night sky are caused by chemical reactions. The compounds in the firework are heated. These hot atoms give off light and that’s what we see. 

    Different elements from the periodic table give off different colors. Lithium or strontium create a red color. Magnesium sparks a white color. Copper ignites a blue color. 

    The weather’s impact

    Weather can make or break a fireworks show.

    It is a delicate balance when it comes to wind. Gusty conditions can be very problematic and blow debris onto spectators.

    Meanwhile, light winds can also be an issue as there is nothing to help disperse the smoke.

    Humidity is also very important. The lower the humidity the brighter fireworks appear. On muggy nights, fireworks can look dimmer and more muted.

  • Fireworks and weather: A perfect balance

    [ad_1]

    Americans look forward to the Fourth of July every year, celebrating with good food, great drinks and even better company. But the celebration always culminates in a star-studded firework display in the sky.

    But did you know, weather can have a major impact on how your firework display looks?

    What You Need To Know

    • Fireworks date back to a tradition from 7th century China

    • Conditions like temperature, rain and wind can affect the display

    • Everything from the visibility to the brightness of the fireworks depend on the weather

    • If you plan to set off fireworks, be mindful of the weather


    Fireworks date back to 7th century China, when the Chinese developed an explosive way to celebrate the victories of war. Since then, modern technology has led to elaborate firework displays across the globe every year.

    But weather has a crucial role in how the display looks to you. Conditions like rain, lightning, wind and temperature all play a role in how visible or even how bright or dim a firework can be. 

    Wind

    One of the most important factors in a firework display is the wind. It can significantly affect how the display goes off. Too much or too little wind can determine how visible the show will be to the spectators below.

    As fireworks explode, they create smoke. That smoke gets pushed around by the wind. 

    Calm winds are not a fireworks friend. During calm wind situations, the firework will explode and the smoke will sit stagnant, limiting the view of the show above. 

    Strong winds, on the other hand, can blow smoke or hot embers onto spectators. Wind must always be monitored closely by those lighting fireworks.

    Temperature and humidity

    Believe it or not, even the temperature and humidity of the air mass can play a role in how a firework show goes off.

    Usually air cools as you head up higher in the sky. But sometimes, on rare occasions, the air actually warms – making it warmer aloft rather than at the surface of the earth. This is called an inversion and when this happens, warm air will trap cooler, more dense air closer to the surface.

    This trapping, also known as a cap, can trap smoke from the exploding fireworks close to the surface as well. This can reduce visibility, making it difficult for spectators to view the show above.

    Humidity also can play a role. When the air becomes humid, there’s a lot more moisture in the air. If the humidity of the air is too high, the colors of the fireworks will dim – becoming less bright as they explode. A drier atmosphere will allow for a brighter, more vivid show.

    You may also find trouble in lightning fireworks if the humidity becomes too high. Use caution if you plan on lightning fireworks on a very humid evening.

    Rain and lightning

    One of the most obvious weather hazards to a firework show is rainfall. Fireworks can be set off in the rain, but they must be located inside a sealed container to be lit. Typically, professional firework shows will have a contingency plan like this in place, in case of rainfall.

    Sealed containers will help to limit the amount of rain and moisture hitting the firework. The less amount of rain and moisture the firework sees, the better chance it has of being lit properly.

    Remember, if you find a fuse won’t light after being lit, discard the firework completely. Place it in a bucket of water and set aside.

    Finally, lightning is considered the most dangerous weather hazard to firework shows. Unlit fireworks that are struck by lightning can become lit and a hazard to those nearby on the ground.

    If lightning is within 10 miles of your area, head inside immediately, bringing all fireworks with you.

    Whatever you do this Fourth of July, celebrate safely. For more firework safety tips, you can visit the National Safety Council.

    One of the most obvious weather hazards to a firework show is rainfall. Fireworks can be set off in the rain, but they must be located inside a sealed container to be lit. Typically, professional firework shows will have a contingency plan like this in place, in case of rainfall.

    Sealed containers will help to limit the amount of rain and moisture hitting the firework. The less amount of rain and moisture the firework sees, the better chance it has of being lit properly.

    Remember, if you find a fuse won’t light after being lit, discard the firework completely. Place it in a bucket of water and set aside.

    Finally, lightning is considered the most dangerous weather hazard to firework shows. Unlit fireworks that are struck by lightning can become lit and a hazard to those nearby on the ground.

    If lightning is within 10 miles of your area, head inside immediately, bringing all fireworks with you.

    Whatever you do this Fourth of July, celebrate safely. For more firework safety tips, you can visit the National Safety Council.

  • How boaters can keep safe this summer

    [ad_1]

    Summer is in full swing, and that means it’s boating season. However, with warmer weather, comes the threat of dangerous thunderstorms.

    Seasoned boaters know all too well how quickly conditions can change on the water but knowing what to do in every situation can save lives.

    How do you know what weather to expect? Is it better to hurry to shore or stick it out? These are a few of the questions we will answer for you ahead.

    What You Need To Know

    • Most boating accidents happen during the summer months

    • Knowing the forecast is the most important step

    • Having a safety plan can help boaters caught in a storm


    Understanding the dangers of weather on the water

    Thousands of boating accidents happen every year leading to injuries and death. Most of these accidents happen during the summer months of June, July and August. 

    Of those accidents, roughly 3-5% of them are caused by weather. Overall, weather was the 8th leading cause of boating accidents in a 2023 study done by USCG. 

    While on the water, there are many hazards to be aware of: lightning, heavy rain and strong winds that can create dangerous waves. Together, these dangers can make the water the worst place to be during a thunderstorm.

    TIP #1: Know before you go

    The first step to safety is taking the right steps to prepare. Before you even hit the waters, knowing the forecast for the day is paramount.

    Checking the forecast through your local National Weather Service office is a great start. If you can, it’s suggested to research the buoy observations to understand current conditions.

    If there is any chance of thunderstorms, it is strongly advised to rethink heading out. Ultimately, it is your choice to decide whether to head out, so as to ensure you are confident in the forecast.

    Weather apps, like the Spectrum News App, can help you make that decision. Additionally, having a NOAA weather radio is a great option.

    TIP #2: Staying weather aware

    Once the decision has been made for a day of boating, the job doesn’t end there. Some days may be tranquil, but other days the weather can be unpredictable and full of unwelcome surprises.

    Keeping an eye out for a few key signs could make all the difference. If you notice skies darkening, winds changing direction, pressure dropping, or simply hearing thunder in the distance, heading back to port is the best decision to make.

    If you think conditions can improve, hanging by a landing until it looks safe will allow you the option to head back out. If conditions get worse, seek dry land.

    TIP #3: Keeping safe during a storm

    If you unfortunately can’t get to land before a storm hits, having a safety plan to protect yourself and guests is essential.

    Thunderstorms are the worst nightmare for boaters. They can create many hazardous conditions like frequent lightning, strong winds, large waves, waterspouts and blinding rain.

    While getting off the water is always the goal if a thunderstorm is about to hit, sometimes that isn’t an option right away. 

    The National Weather Service and U.S. Coast Guard recommends that you:

    In addition to the life jackets, you should have a safety kit available, especially for larger boats. For more on what you should have in your kit, visit here.

    Making the call

    Deciding whether to set sail or stay on land is your decision. Being prepared for the worst every time you are on the water is a must. Remember to always check the forecast, be aware of changing weather conditions, and enact the thunderstorm safety plan when necessary. Doing so will help keep you safe and enjoy boating all season long.

  • 2025 severe weather season more active than average

    [ad_1]

    There is no doubt, 2025 has been busy in the severe weather department. From damaging winds, to large hail, to hundreds of tornadoes, this year has been more active than normal.

    What You Need To Know

    • There have been over 850 tornadoes in the U.S. this year so far

    • The average through May is around 650 tornadoes.

    • Severe weather season continues into June


    The severe weather season quickly ramped up in March in the Mississippi and Ohio River Valleys. It was also active in the south.

    The severe weather didn’t stop there. Virtually the same areas were hit hard in April and May. 

    On the 16th of May, an outbreak of tornadoes impacted Missouri, southern Illinois and Kentucky with several strong tornadoes. In fact, an EF4 tornado hit London, Kentucky. 19 people were killed from severe weather in Kentucky that day. 

    2025 tornadoes by EF scale

    EFU (Undefined): 68

    EF0: 245

    EF1: 406

    EF2: 117

    EF3: 32

    EF4: 5

    EF5: 0

    The severe weather continued into June. Two major metro areas were hit by tornadoes early in the month. The Kansas City region was hit by two tornadoes on the 3rd of the month. The day after, the western suburbs of St. Louis were hit by an EF1 tornado.

    The St. Louis area so far this year has experienced 43 tornadoes. That doubles their annual average, which is around 22 tornadoes. Additionally, 28% of these tornadoes have been strong to violent (EF2+).

    Average number of tornadoes

    Spring is the most active season for tornadoes in the United States, but this year has been more active than average. So far, there have been over 870 tornadoes across the country. On average, 650 tornadoes hit the country into the beginning of June. Here is the average number or tornadoes broken down by month.

    A shift in “tornado alley”

    The tornadoes in 2025 have been most prevalent east of the typical “tornado alley” region, which is in the plains. This year, tornadoes have been focused in the Mississippi and Ohio River Valleys.

    Tornadoes this year have shifted 400 to 600 miles east of the “typical” tornado alley.

    Will this continue to be a trend due to climate change? Time will tell over the next several years. In the meantime, thunderstorms will continue into the summer and so does the risk for severe weather.

  • Breaking down the North American Monsoon season

    [ad_1]

    You’ve all heard the term “monsoon season”, usually applied to a particularly wet period of weather for a region. But, did you know there is a specific cause to a true monsoon season, and it has everything to do with the wind. 

    What You Need To Know

    • Traders off the Indian and Arabia coasts were the first to notice the monsoon pattern

    • Monsoons are large-scale wind shifts that occur in the spring and summer months

    • In the 90s, studies were done to determine if a monsoon existed in North America

    • Rain during a monsoon is not continuous and can vary in intensity year to year



    Monsoons occur in many parts of the globe. Besides the first monsoons observed in India and the Arabian peninsula, areas in Southeast Asia, Australia, North America, Africa and South America feature the annual weather phenomenon.

    How do monsoons form?

    Most of the time, wind in dry areas blows from the land toward the sea. However, by late spring, land areas begin to heat up.

    The heat creates an area of low pressure know as a ‘thermal low’. Nearby bodies of water are also warmed, but not as quickly, so air pressure remains high relative to the land.

    Eventually, the pressure differences get to where the cooler, more humid air over the water is drawn toward the hot, dry air over land, creating the perfect environment for areas of heavy rain to form.

    The North American Monsoon

    Not much was known or studied regarding a monsoon season in North America until the 1990s. The Southwest Arizona Monsoon Project, or SWAMP for short, more or less proved the existence of a monsoon season similar to those studied in other parts of the world.

    While not as strong or persistent as the Indian monsoon, it checks all the boxes of a bona fide monsoon. The wind shift in summer as Mexico and the southwest U.S. warm up starts the process. Flow from dry land areas to moist ocean areas switches and low-level moisture is transported primarily from the Gulf of California and eastern Pacific.

    Monsoon progression

    Like snowflakes or fingerprints, no two monsoon season are ever alike. However, they all follow a fairly predictable cycle with five phases. 

    • Ramp- Up: (June through Early July)

    • Onset: (Late June through Mid July)

    • Peak: (Mid July through Mid August)

    • Late Monsoon: (Mid August through early September)

    • Decay: (Late August through Late September)

    Each phase can differ year-to-year depending on where the subtropical, or monsoon, ridge is located. A stronger ridge can lead to hotter temperatures underneath this dome of high pressure and can result in more moisture transport in from the east.

    On the other hand, a weaker ridge can lead to cooler temperatures and a drier westerly wind influence.

    Results of the North American Monsoon

    Since no two monsoon seasons are ever the same, we can’t always rely on this four-month period to bring the desert southwest much needed rainfall. However, an average monsoon season in a place like Tucson, AZ can net about six inches of rain. This would account for more than half of their annual rainfall. 

    For 2025, the Climate Prediction Center is calling for a better that 50/50 chance at above-average monsoon rain totals. This will help Arizona, where half the state is experiencing extreme or exceptional drought.

  • Weather Explained: Understanding the heat index

    [ad_1]

    Heat index is the temperature that it feels like to the human body and is also referred to as the feels-like temperature or the apparent temperature.

    Oftentimes, it will feel much hotter than what the thermometer reads.

    This is especially true on hot and humid days because the body can’t cool as efficiently. When the heat index is high, people become more susceptible to heat exhaustion or heat stroke.

    Watch the video above to learn how humidity impacts how you cool down, and learn the math behind the science.

  • Tornado reports for the year through April 30

    [ad_1]

    In recent weeks, top stories have featured violent weather with tornadoes, damaging winds, large hail and flooding that injured people and infrastructures, and even caused fatalities.

    How do these values compare to the average? Are we seeing more tornadoes than we used to or is this just par for the course at this time of the year?

    What You Need To Know

    • There have been 689 tornado reports since Jan. 1

    • 2025 ranks second to 2011 for the most tornado reports through the first third of the year

    • Tornado reports are preliminary and these reports are not the same as actual tornadoes numbers



    Tornado reports so far

    If it seems like 2025 has experienced more tornadoes through the first third of the year than normal, the data backs this up. From Jan. 1 through April 30, 2025, the Storm Prediction Center has received 689 tornado reports. 

    However, these are preliminary tornado reports and these reports reports are not the same as actual tornadoes.

    “In realtime, the National Weather Service collects what are called preliminary local storm reports. For tornadoes, these can be thought of as eyewitness reports of the tornado,” explains Matthew Elliot, warning coordination meteorologist at the Storm Prediction Center.

    Reports such as damage or video of a tornado are documented, showing the location of the damage and tornado. Each report will count as one tornado preliminary report.  

    However, Elliot mentioned that sometimes there may be multiple reports of the same tornado, especially longer-track ones, leading to overestimated tornado counts.

    “Some preliminary reports end up not being tornadic after a ground survey has been completed while others are surveyed and entered into the official database, but never have a preliminary local storm report issued,” he said, noting that’s rare, but it does happen.
