  • 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!

  • How to stay safe during extreme heat

    [ad_1]

    Now that summer is here, dangerous heat and humidity will be more common over the next couple months.

    If you’re experiencing extreme heat, it’s important to recognize the signs of heat illnesses and know how to stay safe.

    What You Need To Know

    • High humidity makes extreme heat more dangerous for your body

    • You should limit outdoor activity if you’re under a Heat Advisory or Extreme Heat Warning

    • Everyone is susceptible to heat exhaustion and heat stroke during the summer


    There are many symptoms of heat exhaustion and heat stroke, and it’s important to recognize the signs before going outside. 

    If you or someone you know is ever experiencing any of these symptoms, focus on immediate cooling and hydration.

    There are other factors that can affect your body in the heat, including if the heat is dry or humid. When humidity is high, your sweat can’t evaporate quickly, preventing your body from cooling down.

    Some other factors that can affect you:

    • Age
    • Obesity
    • Dehydration
    • Heart disease
    • Sunburn
    • Medications or illness

    The highest risk groups are the elderly, young children, pets and people with chronic diseases or mental illness.

    Heat safety tips

    Once you know your risks, know what actions to take to stay safe and prevent heat illness.

    • Stay hydrated: Drink plenty of fluids, especially water and electrolytes
    • Stay cool: Spend time in air-conditioned buildings and limit outdoor activity
    • If you have to spend time outside, try to schedule outdoor events early or later in the day when it’s cooler and seek shade
    • Wear and reapply sunscreen, and wear loose, lightweight, light-colored clothing
    • Check on others, including friends, family and neighbors, especially the most vulnerable
    • Never leave children or pets unattended in vehicles

  • 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!

  • Thursday brings July’s full moon, the ‘Buck Moon’

    [ad_1]

    This month’s “Buck Moon” also happens when the moon will be at its closest to Earth for the year.

    What You Need To Know

    • July’s full moon is commonly called the “Buck Moon,” but sometimes goes by “Thunder Moon”

    • It will peak Thursday afternoon but look largest around sunset

    • The moon will appear low in the sky because it’s the full moon closest to the summer solstice


    Full moons’ nicknames typically relate to something from that time of year. July’s full moon is called the “Buck Moon” because this is when bucks’ (male deer) new antlers have grown more sizeable after starting late in the spring.

    Other names include the “Thunder Moon,” as this time of year typically sees a threat for thunderstorms.

    The moon will be at its fullest at 4:36 p.m. EDT, but it’ll still be essentially full when it rises Thursday evening and will appear low in the sky. This happens because it’s the full moon closest to the summer solstice, when the sun is at its highest in the daytime sky, and the moon tracks a correspondingly low path through the night.

    The moon will look even lower than normal because of a phenomenon known as a ‘Major Lunar Standstill,’ when the sun’s gravity drags the moon’s tilted orbit into its most extreme inclination relative to Earth’s celestial equator. This occurs every 18.6 years.

    Here’s the cloud cover forecast for Wednesday evening through Friday evening across the country.

  • 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.

  • Chantal brought heavy rain and significant flooding to the Carolinas

    [ad_1]

    Chantal has become post-tropical as continues to move through the Mid-Atlantic. It’s expected to dissipate later Monday with some additional rainfall and flooding potential across parts of eastern Virginia, Maryland, Delaware and Pennsylvania.

    What You Need To Know

    • Tropical Storm Chantal made landfall near Litchfield Beach, South Carolina on July 6

    • It brought heavy rainfall and significant flooding to parts of North Carolina

    • It was the first storm to make landfall in the U.S. in 2025


    Chantal began as Tropical Depression Three, forming off the coast of northeast Florida. It became Tropical Storm Chantal one day later, on July 5.

    It made landfall just one day after forming, moving inland near Litchfield Beach, South Carolina, as a tropical storm with winds of 60 mph on July 6. Chantal was the first storm to make landfall in the U.S. during the 2025 Atlantic hurricane season.

    The highest winds reported were in Myrtle Beach at the Springmaid Pier, with gusts up to 56 mph. An EF0 tornado also touched down in Wilmington, N.C., causing minor home damage and extensive tree damage.

    Heavy rainfall and flash flooding were the biggest impacts from Chantal. Radar-estimated rainfall totals up 9 to 12 inches were recorded in parts of North Carolina between Raleigh and Greensboro, causing significant flooding around Chapel Hill and nearby rivers.

    Chapel Hill Fire Department said it performed roughly 50 rescues since Sunday morning. First responders also rescued people in Durham after the Eno River hit major flood stage. Flooding on the Haw River shut down I-85 and I-40 in Alamance County after Chantal moved through.


    There are no more watches and warnings in effect.

  • 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.

  • Where to expect tropical activity in July

    [ad_1]

    We’re just over one month into the 2025 Atlantic hurricane season. Forecasters are expecting another active season, so it’s important to know where tropical systems could form this month.

    What You Need To Know

    • July is typically a quiet month for the tropics

    • Tropical activity tends to pick up later in the season

    • Strong hurricanes can still form this month


    Historically, July is still a relatively quiet month across the Atlantic basin for tropical activity. According to NOAA, July only accounts for 7% of the Atlantic’s named storms since 1851, and less than 6% of hurricanes.

    There are a handful of limiting factors working against tropical development this month. Saharan dust outbreaks are still common this time of the year, and sea surface temperatures across the Atlantic’s main development region are still warming up, so tropical waves that track across the length of the Atlantic Ocean and survive to make landfall in the U.S. aren’t too common.

    The most common areas for tropical development this month are closer to land. These home-grown systems can spin up in the Gulf or off the Atlantic coast over the Gulf stream, where waters are slightly warmer and conditions are more favorable. 

    Just because tropical systems don’t usually form in July doesn’t mean they can’t.

    Last year, Hurricane Beryl became the earliest Category 5 storm in the Atlantic basin on record in early July. It made three landfalls, eventually moving inland over the U.S. near Matagorda, Texas, on July 8, 2024 as a Category 1 storm.

    Only three major hurricanes have made landfall in the U.S. during July. Most recently, Hurricane Dennis in 2005. 

    Dennis made landfall on Santa Rosa Island, Florida, as a Category 3 hurricane on July 10. It caused almost $4 billion of damage across the U.S. and Caribbean, and was responsible for 90 deaths, 17 in the U.S.

    The other two major hurricanes to make landfall in July were from the early 1900s. The Gulf Coast Hurricane of 1916 made landfall on July 5, 1916, near Pascagoula, Mississippi, as a Category 3 hurricane, claiming at least 34 lives.

    The 1909 Velasco hurricane made landfall near Velasco, Texas, on July 21, 1909 as a Category 3 hurricane, causing 41 deaths. 

    Development zones expand and tropical activity increases as we get further into summer.

  • Barry made landfall as a tropical depression

    [ad_1]

    Tropical Storm Barry formed on the morning of June 29 over the Bay of Campeche, becoming the second named storm of the 2025 hurricane season.

    What You Need To Know

    • Tropical Storm Barry formed in the Bay of Campeche on the morning of June 29
    • Maximum winds reached 45 mph

    • Barry made landfall as a Tropical Depression across the mountains of northeastern Mexico


    Just like its predecessor, Tropical Storm Andrea, Barry formed and dissipated the same day. Maximum winds only reached 45 mph before Barry moved inland, dissipating across the mountains of northeastern Mexico.

    Barry caused flooding and damage in Quintana Roo, Mexico, where nearly 17 inches of rain fell.

  • Mexico probes contamination from SpaceX rocket explosion

    [ad_1]

    MEXICO CITY (AP) — Mexican President Claudia Sheinbaum said Wednesday that her administration is investigating contamination from a SpaceX facility near the Mexican border in South Texas, and planning its next course of action.

    The announcement follows the June 18 explosion of a Starship rocket while on a stand during a test, which sent a massive fireball into the night sky.

    Pieces of metal, plastic and rocket pieces were reportedly found in the northern state of Tamaulipas, which borders the SpaceX’s Starbase following the explosion.

    On Wednesday, Sheinbaum responded to a reporter’s question during her daily news briefing, saying “there’s a general review underway, (to find out) what international laws they are violating.” She added that her administration would then see what steps to take with the company, because “there is contamination.”

    SpaceX did not immediately respond to a request for comment Wednesday.

    On Tuesday, Tamaulipas Gov. Américo Villarreal demanded a study of whether SpaceX was complying with requirements for where such facilities could be located in relation to population centers.

    Mexican officials had also confirmed debris on a Tamaulipas beach from a failed May 27 Starship launch.
