Northern California forecast: Dense morning fog
Dense morning fog is present in the Valley, Delta, and parts of the Sierra again this morning, but much like the weekend, we expect a sunny afternoon.
CONTINUE TO DRIVE CAUTIOUSLY. 419 NOW AND DRIVING AROUND HERE FEELS MORE LIKE DRIVING AROUND SAN FRANCISCO BAY. TAMARA BERG AS WE TAKE A LIVE LOOK HERE AT OUR STOCKTON SKYCAM. IF YOU SPEND TIME AROUND THE COAST, YOU’VE DEALT WITH FOG. WELL, WE’RE IN THE VALLEY SOUP, IF YOU WILL, AS WE’VE GOT THE FOG LAYER PRETTY THICK AROUND THE REGION. HERE’S A LIVE LOOK FOR FOR RANCHO CORDOVA SKY CAMERA. AND YEAH, YOU CAN SEE FOR FOLKS THAT ARE TRYING TO NAVIGATE TRAVEL EARLY MORNING ON THIS MONDAY ALONG HIGHWAY 50. DEFINITELY SOCKED IN WITH THAT LAYER OF FOG, WHICH OF COURSE CAN OBSTRUCT YOUR VISIBILITY. TEMPERATURES QUITE COOL ACROSS THE VALLEY FLOOR. WE’VE GOT UPPER 40S RIGHT NOW TO 28 DEGREES. WAKING UP IN SOUTH LAKE TAHOE. BELIEVE IT OR NOT, IN THE PAST 24 HOURS, TEMPERATURES HAVE MODERATED UPWARD. SO MANY AREAS HERE. AS YOU LOOK IN THE CENTRAL VALLEY, 5 TO 8 DEGREES UP COMPARED TO 24 HOURS AGO. WE’RE NOTICING A LITTLE DROP OFF IN AUBURN BY ABOUT SEVEN DEGREES. AND THEN THOSE NUMBERS ARE UP RIGHT NOW IN SOUTH LAKE TAHOE BY ABOUT FIVE DEGREES. VISIBILITY, OF COURSE, WILL BE A FACTOR AND A FEATURE DENSE FOG ADVISORY IS IN EFFECT FOR THE ENTIRE CENTRAL VALLEY UNTIL 11:00 THIS MORNING. AND HERE’S WHY. YOU CAN SEE HOW WIDESPREAD THE FOG IS ALREADY KIND OF PLAYING OUT, AND IT’S STILL BRIGHT AND EARLY OUT THERE. WE TYPICALLY TEND TO SEE SOME OF THAT HEAVIER FOG REALLY BUILD, ESPECIALLY AROUND DAYBREAK. BUT RIGHT NOW I’VE GOT VISIBILITY HALF MILE SAC INTERNATIONAL AIRPORT, WE’RE JUST UNDER ABOUT TWO MILES HERE IN DAVIS, HOLDING AT THREE MILES AROUND THE POCKET AREA IN SOUTH SACRAMENTO, BUT AROUND I-5 INTO GALT. WE START TO SEE THAT FOG THICKEN UP A BIT BETTER RIGHT AROUND STOCKTON AT THE AIRPORT RIGHT NOW, WHERE IT’S A MILE AND A QUARTER VISIBILITY TRACY HOLDING RIGHT NOW, JUST A FEW HUNDRED FEET OF VISIBILITY. SO IF YOU’RE NAVIGATING A DELTA, TRAVEL ISLETON OFF TOWARDS TRACY TRIANGLE, BE PREPARED FOR THOSE SUDDEN DROPS IN VISIBILITY. AND NOTICE THAT EVEN ABOUT 7:00 THIS MORNING, LOOKS TO HOW HEAVY THE FOG IS ALL ACROSS THE CENTRAL VALLEY AND EXTENDING INTO THE DELTA AND ALL THE WAY TO THE BAY AREA. SO IF YOU ARE A SUPER COMMUTER GOING THAT DIRECTION, BE PREPARED FOR A LITTLE BIT SLOWER TRAVEL, NAVIGATING, GETTING THROUGH SOME OF THE REDUCED VISIBILITY. WE HEAD TOWARDS. NOON 1:00 TIMEFRAME. THE FOG STARTS TO BREAK UP. IT STARTS TO MIX OUT AND LIFT, AND THEN EVENTUALLY WE’RE LOOKING AT MOSTLY SUNNY SKIES. TODAY, JUST SOME HIGH CLOUDS WILL DRIFT INTO VIEW THROUGHOUT MUCH OF YOUR MONDAY. HIGH PRESSURE WILL BE THE MAIN FEATURE AS WE GET INTO THE START OF THIS WEEK, KEEPING US WITH A MOSTLY SUNNY LANDSCAPE. THOSE MORNINGS WITH FOG, PRETTY STAGNANT AIR CONDITIONS, BUT AT LEAST STABLE CONDITIONS AS WE GET INTO THE BACK HALF OF THE WEEK. THURSDAY, OF COURSE, BEING THANKSGIVING, IF YOU’RE TRAVELING UP AND DOWN THE ENTIRE STATE LOOKS GOOD FOR THE MOST PART. THE ONLY THING YOU HAVE TO PLAN FOR IS FOG AND AN INCREASE IN CLOUDS. WE’LL SEE MORE CLOUDS AROUND ON FRIDAY AS WELL. STILL DRY FOR RETURN TRAVEL OR GOING OUT. GETTING SOME OF THOSE BLACK FRIDAY DEALS. ONCE WE GET INTO YOUR EVENING THOUGH, THIS SYSTEM COMES BARRELING IN. AND THIS SYSTEM AT THIS POINT, WITH THIS FORECAST MODEL COULD DELIVER SOME RAIN SHOWERS TO THE VALLEY AS EARLY AS SATURDAY AND SOME ELEVATION, HIGH ELEVATION SNOWFALL AS WELL, SOMETHING WE’LL DEFINITELY KEEP AN EYE ON THROUGHOUT THE REST OF THE WEEK. BUT AS YOU’RE EYEING THIS FORECAST HERE, LOOK AT THAT LITTLE DAY TO DAY CHANGE TO MOSTLY SUNNY SKIES ALL THE WAY THROUGH THURSDAY. THE THANKSGIVING HOLIDAY WITH UPPER 50S AND LOW 60S TO BE EXPECTED. I’VE GOT THE ONE CHANCE FOR RAIN THIS WEEK IN YOUR SATURDAY FORECAST, SO JUST BE PREPARED, ESPECIALLY IF YOU’RE, YOU KNOW, GOING SOMEWHERE FOR THE ENTIRE LONG HAUL. MAYBE YOU HAVE THURSDAY AND FRIDAY OFF.
