AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HANFORD CA
500 AM PDT TUE JUN 30 2026
UPDATE
UPDATED AVIATION SECTION.
KEY MESSAGES
1. DRY AND BREEZY CONDITIONS CREATE ELEVATED FIRE RISK THIS
WEEK, ESPECIALLY IN THE MOJAVE DESERT.
2. BELOW NORMAL TEMPERATURES CONTINUE ACROSS THE AREA.
3. PRACTICE SAFETY AROUND LAKES, RIVERS AND STREAMS, AS WATER
IS STILL RUNNING COLD.
DISCUSSION
AS THE STRONG SHORTWAVE MOVES OUT OF OUR AREA, A WEAKER TROUGH
WILL BE LEFT ALOFT, CONTINUING TO CAUSE BELOW NORMAL
TEMPERATURES THROUGHOUT THE REGION FOR THE REMINDER OF THE
WORKWEEK. THIS TROUGH WILL ALSO CAUSE INCREASED WINDS AT THE SAN
LUIS RESERVOIR THROUGH THURSDAY EVENING, THOUGH MAINLY IN THE
LATE MORNING INTO THE EARLY EVENING AND CALMER WINDS OVERNIGHT.
A LAKE WIND ADVISORY HAS BEEN ISSUED FOR THAT AREA DURING THAT
TIME PERIOD.
THE TROUGH WILL BEGIN TO WEAKEN BY SATURDAY, LEADING TO A SLIGHT
WARM-UP THAT WILL BRING TEMPERATURES BACK TO AROUND NORMAL FOR
THIS TIME OF YEAR, WHICH WILL REMAIN STEADY INTO EARLY NEXT
WEEK. THIS WILL MAINLY BE DUE TO INCREASED 500MB HEIGHTS OVER
CENTRAL CALIFORNIA, AS THE RIDGE THAT MAY DEVELOP IS CURRENTLY
MODELED TO SET UP OVER THE FOUR CORNERS REGION. LOOKING INTO THE
LONG TERM, THE CLIMATE PREDICTION CENTER HAS OUR CWA IN THE
LEANING ABOVE NORMAL CATEGORY FOR TEMPERATURES IN BOTH THE 6 TO
10 AND 8 TO 14 DAY OUTLOOKS, SO EVEN WARMER TEMPERATURES MAY BE
IN STORE FOR THE VALLEY DURING THOSE TIME PERIODS.
