    Northern California forecast: Cool with a few regional showers

    NOW, LET’S TAKE THIS LIVE. LOOK OUTSIDE IN SACRAMENTO. WHERE? YEAH, JUST A FEW CLOUDS AROUND EARLY. WE’RE AT 62 DEGREES RIGHT NOW. WINDS SOUTHEAST AT ABOUT FIVE MILES PER HOUR. NOW, WE DO HAVE SOME ACTIVITY ON THE RADAR. SO HERE LOCALLY AROUND SACRAMENTO WE’RE STILL LOOKING AT DRY CONDITIONS, MAINLY CLEAR SKIES. BUT AS WE TAKE A LOOK AT WE’RE HEADING UP TOWARD TEHAMA COUNTY AND RED BLUFF. THAT’S WHERE WE’RE SEEING SOME SHOWER ACTIVITY THIS MORNING. WE’VE SEEN A FEW IN PARTS OF GLENN COUNTY, COLUSA AND LAKE COUNTIES THERE AS WELL, AND THEN HEADING OVER INTO PLUMAS COUNTY, SEEING A FEW SHOWERS HERE JUST TO THE NORTH OF CRESCENT MILLS. THOSE ARE MOVING THEIR WAY NORTHWARD, AND WE DO EXPECT TO SEE MORE ACTIVE WEATHER AS WE HEAD INTO THE AFTERNOON, ESPECIALLY IN THE SIERRA. AND THEN AGAIN IN THAT COASTAL RANGE, LIKELY TO SEE SOME SHOWERS THERE, TOO. TOMORROW AFTERNOON. MORE CHANCES FOR SHOWERS AND THUNDERSTORMS, PRIMARILY IN THE SIERRA, MAYBE A LITTLE BIT INTO THE COASTAL HILLS TOO. AND THEN FRIDAY, JUST A SLIGHT CHANCE IN THE SIERRA DRY CONDITIONS. SUNNY FOR US ON SATURDAY. SUNDAY THOUGH, ANOTHER CENTER OF LOW PRESSURE STARTS MOVING ITS WAY IN THIS, BRINGING WITH IT MORE CLOUDS, MORE CHANCES FOR AT LEAST A FEW SHOWERS ALONG THE COAST AND THEN IN THE SIERRA VALLEY WILL LIKELY STAY DRY. AND THEN AS WE GET INTO NEXT WEEK, ANOTHER RIDGE OF HIGH PRESSURE STARTS MOVING IN. AND THAT IS GOING TO BRING SOME WARMER TEMPERATURES BACK TO OUR FORECAST. THE SEVEN DAY FORECAST FOR TODAY IN THE SIERRA 62 DEGREES CHANCES FOR SHOWERS TOMORROW 65 WARMING UP INTO THE 70S OVER THE WEEKEND FOR THE FOOTHILLS. SLIGHT CHANCE FOR A SPRINKLE OR TWO TODAY. JUST MAINLY, MOSTLY CLOUDY SKIES WITH TEMPERATURES IN THE UPPER 70S AND THEN IN SACRAMENTO. TODAY THAT FORECAST HIGH, TOPPING OUT AT 79 DEGREES. HOW NICE IS THAT GETTING INTO THE UPPER 80S FOR US ON SATURDAY. AND A FEW MORE CLOUD

  • Video: Dust devil so big it could be seen for miles forms at Kentucky fairgrounds

    Yeah, I’ve seen some weird at the airport, but I seen that. What the hell is that that stuff. Oh

    This massive Kentucky dust devil was so big it could be seen for miles

    A dust devil created a wild sight at the fairgrounds in Louisville, Kentucky.It could be spotted for miles, swirling around, hundreds of feet tall on Wednesday. Dave Tors was at UPS Worldport when he took a video of the large vortex (seen in above video).Other videos show it formed where construction is happening near the Kentucky Expo Center.Even though temperatures have been cooler than normal, the sunny skies, light breezes, and quickly warming temperatures made this possible.Dust devils can form when daytime sunshine heats the surface, causing rising air and low pressure to form at ground level. That low pressure continues to pull in more heated and swirling air until the circulation is self-sustaining. The same process that causes lifting of the warm air will eventually bring cooler air into the circulation, weakening the dust devil.While typically smaller and less intense than tornadoes, some dust devils can create wind speeds over 60 mph and cause damage.
