Northern California forecast: Sierra red flag warning this weekend

NOT TOO SURPRISING LOOKING AT THE RADAR. SO HERE’S LAKE TAHOE STATE LINE RIGHT HERE JUST TO THE EAST OF SOUTH LAKE. AND YEAH, THESE LITTLE CELLS CREEPING ALONG ON THE EAST SLOPE. THE RAIN NOT REACHING THE AIRPORT IN SOUTH LAKE TAHOE, BUT YOU CAN SEE A COUPLE LITTLE LIGHTNING STRIKES BEING DETECTED IN NORTHERN ALPINE COUNTY WITHIN THE PAST 45 MINUTES OR SO. THE MORE INTENSE LIGHTNING WAS FARTHER OFF TO THE SOUTH, SOUTHERN ALPINE COUNTY INTO EASTERN TUOLUMNE COUNTY. SOME OF THIS RAIN IS REACHING THE GROUND, BUT NOT ALL OF IT, AS WE CALL IT DRY LIGHTNING. AND THAT CONCERN IS GOING TO CONTINUE THROUGH THIS WEEKEND. IT WILL EXPAND NORTH INTO THE TAHOE AREA. THERE’S A VIEW OF THE EDGEWOOD GOLF COURSE THERE. YOU CAN SEE THE CAMERA SHAKING AROUND A LITTLE BIT. THERE IS A BREEZE COMING AS THOSE SHOWERS PASS BY. AND TONIGHT IN THE VALLEY. YEAH, IT’S GOING TO STAY HOT AGAIN THIS EVENING. IT WILL COOL OFF SOME TOMORROW MORNING COMPARED TO WHERE WE STARTED TODAY. FOOTHILLS STILL GOING TO BE A VERY WARM NIGHT, BUT SATURDAY AN INCREASE IN CLOUDS WITH THAT INCREASE IN MONSOONAL MOISTURE. YOU SAW THOSE SIERRA THUNDERSTORMS. WELL, THAT’S GOING TO HELP TO PUT A CAP ON THE TEMPERATURES FOR THE VALLEY AND THE FOOTHILLS. SO HERE’S THE BROAD VIEW. YOU CAN SEE ALL OF THESE SHOWERS AND THUNDERSTORMS ROTATING AROUND OUR BIG AREA OF HIGH PRESSURE OVER THE FOUR CORNERS. THAT HIGH OF COURSE, WHAT WE’VE BEEN BLAMING FOR THIS INTENSE HEAT OVER THE LAST WEEK, ALMOST TWO WEEKS AT THIS POINT. BUT TOMORROW IT IS GOING TO SEND SOME MOISTURE OUR WAY. LOOK AT THIS FUTURECAST SHOWING A FEW CLOUDS ACROSS THE VALLEY. TO START THINGS OFF, IT MAY BE A MUGGY MORNING FOR THE VALLEY MUGGIER THAN WHAT WE’VE SEEN RECENTLY. TEMPERATURES IN THE 70S, BUT WITH THESE CLOUDS HANGING AROUND THAT SHOULD KEEP AFTERNOON TEMPERATURES IN THE UPPER 90S FOR MOST, A COUPLE OF SPOTS MAY HIT 100 DEGREES, BUT LET’S FOCUS ON THE SIERRA SHOWERS AND A COUPLE THUNDERSTORMS POPPING UP AT ABOUT ONE 2:00 IN THE AFTERNOON. AND REMEMBER, THIS MODEL IS PICKING UP ON POTENTIAL RAIN. IT IS NOT SHOWING US WHERE THERE COULD BE LIGHTNING. YOU DO NOT NEED TO HAVE RAIN IN ORDER TO HAVE LIGHTNING STRIKES. SO I WANT TO SHOW YOU KIND OF A DIFFERENT VERSION OF THIS MODEL. THESE AREAS IN BLUE REPRESENTING WHERE THERE MAY BE ENOUGH ENERGY FOR THE ATMOSPHERE TO PRODUCE SOME LIGHTNING. TOMORROW AFTERNOON. AND NOTICE HOW THAT GOES ALL THE WAY UP THE CREST OF THE SIERRA AROUND THE TAHOE REGION, DOWN THROUGH ALPINE COUNTY INTO EASTERN TUOLUMNE COUNTY. THAT DOES NOT GUARANTEE WE WILL SEE LIGHTNING IN THOSE AREAS, BUT THAT DOES SHOW YOU THAT POTENTIAL IS THERE. SO WE’RE URGING PEOPLE, IF YOU HAVE PLANS TO BE OUTDOORS, ESPECIALLY TOMORROW IN TAHOE, KEEP AN EYE ON THE SKY. IF YOU’RE OUT ON THE WATER AND THE CLOUDS START TO LOOK A LITTLE THREATENING, IT’S TIME TO COME IN. AND OF COURSE, IF YOU HAVE PLANS TO BE OUTDOORS, ANYTHING INVOLVING OPEN FLAMES, YOU JUST GOT TO BE CAREFUL. A RED FLAG WARNING WILL BE IN EFFECT FOR ALL OF THESE LOCATIONS TOMORROW. TEMPERATURES STAYING IN THE 80S AND TRUCKEE AND TAHOE AGAIN WITH THOSE THUNDERSTORM CHANCES POPPING UP INTO THE AFTERNOON. NOT EXPECTING MUCH RAIN. IT’S MORE THE LIGHTNING CHANCE THAT WE ARE FOCUSING ON THERE. IT IS GOING TO BE DRY AND SHOULD BE LIGHTNING FREE INTO THE FOOTHILLS, BUT WE’LL SEE AN INCREASE IN CLOUDS. PLACERVILLE AND JACKSON IN THE UPPER 90S. BUT THAT AFTER STARTING CLOSE TO 80 DEGREES AT THE COAST, CERTAINLY BETTER HERE. FAIRFIELD WILL STAY IN THE 80S AS THE ONSHORE BREEZE INCREASES. SAN FRANCISCO IN THE 70S, SAN JOAQUIN VALLEY UPPER 90S TO NEAR 100 DEGREES. CERTAINLY MORE COMFORTABLE THAN WHERE WE’VE BEEN LATELY. AND A LOT OF SPOTS IN THE SACRAMENTO VALLEY WILL ALSO STAY IN THE MID TO UPPER 90S TOMORROW, WITH A COUPLE LOCATIONS JUST BARELY BREAKING THE 100 DEGREE MARK. SO HERE’S THE SEVEN DAY FORECAST FOR THE VALLEY. LOOKING AT TEMPERATURES IN THE MID 90S THROUGH MOST OF NEXT WEEK. SOUNDS PRETTY GOOD AT THIS POINT. SOUNDS GREAT. IT’S GOING TO FEEL SO MUCH BETTER. NICE TO NOT SEE ANY TRIPLE DIGITS. IT’S BEEN WEEKS. THIS IS LIKE SUCH A RELIEF. IT’S KIND OF SAD THOUGH THAT LIKE OH 99 OR 90S. YEAH THAT’S GREAT. THE AVERAGE IS NOW 95.
