CURRENT GOES-WEST SATELLITE IMAGERY SHOWS GENERALLY CLEAR SKIES ACROSS MUCH OF INTERIOR NORTHERN CALIFORNIA THIS MORNING WITH THE EXCEPTION OF A FEW LOW LEVEL CLOUDS OVER PARTS OF THE MOUNTAINS.
TEMPERATURES ARE CURRENTLY IN THE 50S IN THE VALLEY AND FOOTHILLS, AND 30S TO 40S IN THE MOUNTAINS, VALID AT 245 AM PDT. DRY AND WARM WEATHER WILL PREVAIL TODAY, WITH JUST SOME LOCALLY BREEZY NORTHERLY FLOW. ACTIVE WEATHER WILL RETURN TO THE REGION VERY LATE TONIGHT, AS A WEATHER SYSTEM DROPS DOWN FROM THE GULF OF ALASKA BRINGING SHOWERS, MOUNTAIN SNOW, ISOLATED THUNDERSTORMS, GUSTY SOUTHWEST WINDS AND MUCH COOLER TEMPERATURES ON SATURDAY.

PRECIPITATION FIRST LOOKS TO ARRIVE TO FAR NORTHWESTERN CALIFORNIA LATE FRIDAY NIGHT, AND SPREADS INLAND SATURDAY. LATEST GUIDANCE FROM WPC SHOWS STORM TOTAL QPF AMOUNTS OF 0.50" TO 1.25" IN THE VALLEY, AND 1" TO 2.25" IN THE FOOTHILLS AND MOUNTAINS. LOCALLY HEAVIER AMOUNTS WOULD BE POSSIBLE WITH ANY THUNDERSTORMS THAT DEVELOP, AND THERE IS A 15-25% PROBABILITY OF THUNDERSTORM DEVELOPMENT ON SATURDAY, WITH BEST CHANCES NORTH OF INTERSTATE 80.

PEOPLE SHOULD PLAN AHEAD FOR THE LATE-SEASON WINTER WEATHER, AND CHECK THE FORECAST AND ROAD CONDITIONS BEFORE TRAVELING IN THE MOUNTAINS THIS WEEKEND AS SNOW COVERED ROADS, CHAIN CONTROLS AND TRAVEL DELAYS WILL ALL BE POSSIBLE.
