AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HANFORD CA
1229 AM PDT SUN OCT 5 2025
KEY MESSAGES
1. SEASONABLY WARM TEMPERATURES WITH DRY CONDITIONS ARE IN STORE
TODAY THROUGH MUCH OF THE UPCOMING WEEK.
2. ANOTHER LOW PRESSURE SYSTEM WILL BRING THE NEXT CHANCE FOR
PRECIPITATION FRIDAY AND SATURDAY.
DISCUSSION
TODAY'S HIGHS ARE PROJECTED TO BE SLIGHTLY WARMER THAN
YESTERDAY'S, AND A WARMING TREND WILL CONTINUE THROUGH THE
MIDDLE OF THE WEEK. MANY VALLEY AND DESERT LOCATIONS WILL REACH
THE 80'S FOR AT LEAST THE NEXT FEW DAYS, WITH INCREASING CHANCES
OF HIGHS REACHING AT LEAST 85 DEGREES IN THE TYPICAL WARMEST
LOCATIONS BY MONDAY (50-75 PERCENT), WHICH WOULD STILL BE
SEASONABLY WARM FOR THIS TIME OF YEAR. SLIGHTLY HIGHER
PROBABILITIES ARE SHOWN FOR TUESDAY BEFORE LOWERING A BIT FOR
WEDNESDAY AND THURSDAY. ENSEMBLE AND DETERMINISTIC GUIDANCE ARE
CONSISTENT IN TERMS OF SHOWERING A RIDGE OF HIGH PRESSURE THAT
WILL BUILD ALONG THE WEST COAST.
AS FOR LATER IN THE WEEK, WE CONTINUE TO SEE MAINLY A SLIGHT
CHANCE (15-25%) FOR PRECIPITATION ON FRIDAY INTO SATURDAY
THROUGHOUT THE REIGN DUE TO ANOTHER APPROACHING TROUGH OF LOW
PRESSURE FROM THE PACIFIC NORTHWEST. MUCH UNCERTAINTY REMAINS
IN TERMS OF TIMING AND TRACK OF ANY MOISTURE THAT FLOWS INTO THE
REGION. ALTHOUGH, IT APPEARS THE DEEPER MOISTURE WILL BE IN
SOUTHERN CA, AS WELL AS THE DESERTS OF SOUTHEASTERN CALIFORNIA
INTO ARIZONA, WHILE WE WILL BE IN THE WESTERN PERIPHERY. THUS,
WE ANTICIPATE MAINLY LIGHT PRECIPITATION AT THIS TIME, ALTHOUGH
WE COULD SEE SLIGHTLY HIGHER AMOUNTS IF ANY THUNDERSTORMS
DEVELOP.
THE LATEST OUTLOOKS FROM THE CLIMATE PREDICTION CENTER ARE NOW
SHOWING CHANCES FOR BELOW AVERAGE TEMPERATURES AT AROUND
40-50 PERCENT AND ABOUT A 50-60 PERCENT CHANCE OF ABOVE AVERAGE
PRECIPITATION FOR BOTH THE 6-10 AND 8-14 DAY PERIODS.
