DISCUSSION
THE TROUGH THAT LED TO THE THUNDERSTORM ACTIVITY THIS AFTERNOON
WILL REMAIN OFFSHORE THROUGH THE NEXT WEEK OR SO, BUT IS AS OF
NOW NOT FORECASTED TO PRODUCE SIMILAR ACTIVITY THROUGH THAT TIME
PERIOD. CHANCES FOR THUNDERSTORMS WILL STILL BE PRESENT, BUT
WILL REDUCE SIGNIFICANTLY FROM TOMORROW TO 5 TO 10% ON MOST DAYS
AND APPROACHING 15% ON BOTH FRIDAY AND SUNDAY. SO WHILE THE
RISK FOR THUNDERSTORMS WILL DECREASE, THE COOLER THAN NORMAL
TEMPERATURES ARE EXPECTED TO STICK AROUND THROUGH THIS WEEK. THE
COOLING TREND WILL CONTINUE THROUGH TOMORROW, RESULTING IN MUCH
OF THE VALLEY REACHING THE LOW 90'S SOUTH OF FRESNO AND THE
UPPER 80'S NORTH OF FRESNO. THE MOJAVE DESERT IS ALSO EXPECTED
TO SEE HIGHS BELOW TRIPLE DIGITS.
AS THE TROUGH BEGINS TO BROADEN OVER THE WEEKEND, TEMPERATURES
WILL SLOWLY INCREASE, THOUGH ARE EXPECTED TO REMAIN IN THE 90'S
IN THE VALLEY. HOWEVER, THE DESERT IS EXPECTED TO SEE THE
RETURN OF TRIPLE DIGITS BY SUNDAY INTO MONDAY. FROM THE WEEKEND
ONWARDS, TEMPERATURES ARE EXPECTED TO REMAIN STEADILY NEAR
NORMAL FOR THIS TIME OF YEAR. LOOKING TO THE LONG TERM FORECAST,
THE CLIMATE PREDICTION CENTER HAS INCREASED THE LIKELIHOOD FOR
ABOVE NORMAL TEMPERATURES IN CENTRAL CALIFORNIA TO LIKELY ABOVE
AT A 50-60% PROBABILITY.
