DISCUSSION
HIGH PRESSURE OVER THE WEST COAST IS BEGINNING TO WEAKEN AS
WESTERLY ZONAL FLOW TAKES HOLD OF THE REGION. WHILE THE PASSAGE
OF A DISTURBANCE WILL TARGET THE PACIFIC NORTHWEST, THE INCREASE
IN THE WESTERLY FLOW ALOFT WILL ALLOW FOR A SURGE OF COOLER
MARINE AIR INTO THE CENTRAL VALLEY. THEREFORE, THE CENTRAL
CALIFORNIA INTERIOR WILL SEE A SLOW DROP IN TEMPERATURES AND DRY
CONDITIONS. WITH A SIGNIFICANT ONSHORE PUSH OF COOLER AIR,
ENOUGH OF A GRADIENT WILL EXIST TO GENERATE STRONG WINDS OVER
THE COASTAL RANGE. IN ADDITION, PROBABILITY OF EXCEEDANCE (POE)
OF REACHING 95F DEGREES IS ONLY AT 10 AND 30 PERCENT ACROSS THE
SAN JOAQUIN VALLEY SATURDAY. AFTERWARD, POE OF REACHING 95F
DEGREE FALLS BELOW 10 PERCENT ON SUNDAY. BY MONDAY, POE OF 90F
DEGREES WILL RANGE FROM 20-50 PERCENT WITH THE HIGHER
PERCENTAGES OVER SOUTHWEST KERN COUNTY. THEREFORE, CONFIDENCE IS
HIGH THAT TEMPERATURES WILL GO INTO A COOLING TREND WITH MAX
TEMPERATURES STRUGGLING TO REACH 90F DEGREES BY TUESDAY. AT
WHICH TIME, POE OF REACHING 90F DEGREES FALLS BELOW 10 PERCENT.
LITTLE RECOVERY WILL BE SEEN UNTIL THE MIDDLE OF NEXT WEEK.
DURING THIS TIME, A VERY SLIGHT CHANCES (5-10 PERCENT) OF
PRECIPITATION WILL EXIST AND REMAIN CONFINED TO THE HIGHEST
POINTS OF THE SIERRA NEVADA RANGE.
WITH THESE WARMING TEMPERATURES, WATER WAYS WILL BE RUNNING
COLD. EXERCISE CAUTION AROUND LAKES, RIVERS, AND STREAMS AS EVEN
THE MOST EXPERIENCED SWIMMERS CAN LOSE DEXTERITY IN COLD WATER.
