STARTING TO DEVELOP IN PARTS OF THE VALLEY. WE WANT TO CHECK IN NOW WITH METEOROLOGIST OPHELIA YOUNG. SO OPHELIA, IS THIS GOING TO STICK AROUND OVERNIGHT? YES. IN FACT THIS IS FOG IN STOCKTON THAT NEVER LEFT TODAY. THEY’VE BEEN SITTING IN THIS HAZE FOR PRETTY MUCH ALL OF THEIR SUNDAY. IT DID PULL BACK IN THE SACRAMENTO AREA A LITTLE FURTHER NORTH, AND WE GOT TO ENJOY HIGHS IN THE UPPER 50S TODAY. STILL COOL COMPARED TO WHAT’S NORMAL WHICH IS 62 OUR LOW. HOWEVER WE GOT DOWN TO 41 DEGREES. THAT’S ABOUT NORMAL. AND AS THAT DEW POINT, THAT’S WHERE THE FOG CAME FROM. ALSO CLEAR SKIES AND LIGHT WINDS. THAT’S WHAT WE’RE SEEING RIGHT NOW. 50 DEGREES IN THE SACRAMENTO VALLEY, A LITTLE COOLER FURTHER SOUTH IN THE SAN JOAQUIN VALLEY, WHERE THAT FOG IS SITTING OVER. WE ALSO HAVE 48 IN THE FOOTHILLS OF THE SIERRA, COMING IN AT 36 DEGREES CURRENTLY. HERE’S A CLOSER LOOK AT THAT FOG OVER STOCKTON RIGHT NOW. AGAIN, IT DEVELOPED OVERNIGHT. NEVER LEFT TODAY. YOU CAN SEE IT STRETCHING ON THE IMAGERY ALL THE WAY OUT TO CONCORD, DOWN TRACY, AND EVEN A LITTLE BIT INTO MODESTO. AGAIN, IT DEVELOPED OVERNIGHT. IT DID PULL BACK FOR MOST SPOTS. LOOKS LIKE STOCKTON SAT AND FOG ALL DAY, BUT THAT FOG IS NOW BEGINNING TO SPREAD ONCE AGAIN, OVERHEAD AND BACK UP INTO THE SACRAMENTO AREA. HIGH PRESSURE SITTING ON THE WEST COAST. NO SURPRISE THE FOG DEVELOPED. HIGH PRESSURE. SOMETIMES RESPONSIBLE FOR THAT. WE HAVE CLEAR SKIES OVERHEAD A LITTLE FURTHER UP IN THE ATMOSPHERE. WE HAVE LIGHT WINDS AND ALSO THAT THAT MOISTURE IN THE AIR. TOMORROW MORNING AS WE STEP OUT, DENSE FOG ADVISORY WILL BE IN EFFECT. THAT DOES MEAN IF YOU’RE GOING TO BE ON THE ROADS, YOU’LL WANT TO PREPARE FOR POOR VISIBILITY A QUARTER MILE OR LESS. GIVE YOURSELF A FEW MINUTES TO GET TO WHEREVER YOU NEED TO GO TOMORROW FOR YOUR MONDAY MORNING. NOW THAT FOG AGAIN, YOU SEE IT IN STOCKTON THAT’S GOING TO STRETCH UP INTO THE SACRAMENTO AREA, EVEN UP TOWARDS YUBA CITY. IT LOOKS LIKE IT’S GOING TO LINGER AROUND FOR OUR MORNING COMMUTE BEFORE FINALLY PULLING BACK AROUND 9:00 10:00 OR SO. BY LUNCHTIME, MOST AREAS SHOULD FIND THEMSELVES WITH SUNNIER SKIES. ALSO TEMPERATURES A LITTLE WARMER THAN TODAY. WE’RE LOOKING AT LOW 60S FROM YUBA CITY ALL THE WAY DOWN TO STOCKTON. UPPER 50S. STILL IN MODESTO WE HAVE UPPER 50S ALSO IN THE FOOTHILLS OF TRUCKEE AND SOUTH LAKE TAHOE. YOU’LL TOP OUT WITH TEMPERATURES IN THE MID 50S TOMORROW. THIS WEATHER IS GOING TO BE A REPEAT PRETTY MUCH EVERY DAY, ALL THE WAY THROUGH TO THURSDAY IS THANKSGIVING. THANKSGIVING DAY HIGHS MID 60S IN THE COAST. IN THE VALLEY. YOU’RE GOING TO STICK AROUND HERE 60 DEGREES IN THE FOOTHILLS. ALSO AROUND 60. AND IN THE SIERRA YOU’RE LOOKING AT TEMPERATURES NEAR 56 DEGREES. A CLOSER LOOK AT YOUR DAY IN THE VALLEY. IF YOU’RE GOING TO DO LUNCH TIME WITH FAMILY. 55 DEGREES A MIXTURE OF SUN AND CLOUDS ON THAT DAY. BY 3:00, AS WE GET DINNER STARTED, 60 DEGREES EARLY DINNER, I GUESS AT 6:00. COOL. WITH TEMPERATURES FALLING BACK INTO THE 50S AND BY NINE IT WILL BE PRETTY CHILLY. TEMPERATURES WILL BE DOWN INTO THE 40S BY THE END OF YOUR EVENING, BUT UP UNTIL THEN, GREAT! LOOK AT YOUR SEVEN DAY FORECAST WITH TEMPERATURES RIGHT AROUND 60. EVEN THROUGH BLACK FRIDAY, WE ARE WATCHING UNSETTLED WEATHER RETURN WITH BREEZES IN THE VALLEY SATURDAY AND SUNDAY, COOLER WEATHER AND SOME POSSIBLE SNOW FOR THE SIERRA. WE’LL KEE
