KEY MESSAGES...
1. TEMPERATURES BELOW SEASONAL AVERAGES WILL CONTINUE INTO NEXT
WEEK BEFORE A WARMING TREND RETURNS TEMEPRATURES TO AVERAGES
MIDWEEK.
2. PRECIPITATION CHANCES INCREASE INTO THE WEEKEND, WITH THE
BEST CHANCES ON SUNDAY. THE GREATEST PROBABILITIES WILL ALSO BE
IN THE DESERT AND SOUTHERN MOUNTAIN AREAS.
DISCUSSION...
A DISTURBANCE PUSHING INTO THE PACIFIC NORTHWEST CONTINUES ITS
DECENT INTO NORTHERN CALIFORNIA THIS EVENING. FOR CENTRAL
CALIFORNIA, THE DISTURBANCE WILL INFLUENCE TEMPERATURES AND
WINDS OVER THE NEXT FEW DAYS. WHILE THE CHANCES OF PRECIPITATION
FROM THIS DISTURBANCE WILL BE VERY LIMITED, THE AREA HAS SEEN
AND WILL CONTINUE TO OBSERVE BELOW NORMAL TEMPERATURES AND
BREEZY CONDITIONS. THE DROP IN TEMPERATURES HAVE BEEN ABOUT
10-15 DEGREES WITH WIND GUSTS REACHING 15-20 MPH. WHILE
VARIATIONS WILL OCCUR IN THE COMING DAYS, THESE CONDITIONS WILL
PERSIST THROUGH THE WEEKEND WHILE THE DISTURBANCE RESIDES OVER
THE WEST COAST.
TAKING A CLOSER LOOK, THE PROBABILITY OF EXCEEDANCE (POE) OF
REACHING 90 DEGREES WILL NOT GO ABOVE 50 PERCENT UNTIL THURSDAY
OF NEXT WEEK WITH THE POE OF 95 DEGREES JUST BELOW 30 PERCENT.
THEREFORE, WHILE 90S WILL RETURN TO THE SAN JOAQUIN VALLEY, GOOD
WELL ABOVE SEASONAL NORMAL VALUE HAVE VERY LITTLE CHANCE OF
OCCURRING DURING THE NEXT SEVEN DAYS.
HURRICANE MARIE, WHILE EXPECTED TO PROGRESS IN A WESTWARD
DIRECTION, WILL STILL INFLUENCE CENTRAL CALIFORNIA’S WEATHER.
INTEGRATED WATER VAPOR TRANSPORT IS STILL EXPECTED TO SURGE
TOWARD SOUTHERN CALIFORNIA AND REACH OVER PORTIONS OF CENTRAL
CALIFORNIA. WITH THE BEST CHANCES OVER THE MOJAVE DESERT, SOME
MOISTURE WILL SPREAD TOWARD AREAS IN KERN AND TULARE COUNTIES.
THE PROBABILITY OF MEASURABLE PRECIPITATION (POP) OF RECEIVING A
TENTH (0.10”) OF AN INCH RISES TO 20-30 PERCENT SUNDAY MORNING
WITH A SLIGHT RISE IN POP BY SUNDAY AFTERNOON. IN ADDITION, THE
POP FOR A QUARTER OF AN INCH (0.25”) IS AT 15 PERCENT FOR THE
SAME TIME FRAME. AGAIN, SOUTHERN CALIFORNIA IS MORE FAVORED TO
RECEIVE MEASURABLE PRECIPITATION WITH THE SURGE OF MOISTURE
SHIFTING AWAY FROM CENTRAL CALIFORNIA ON MONDAY.
