AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HANFORD CA
1009 PM PDT FRI MAR 28 2025
UPDATE
UPDATED 06Z AVIATION.
KEY MESSAGES
* LIGHT PRECIPITATION IS POSSIBLE UNTIL SATURDAY, MAINLY ALONG
THE SIERRA AND TEHACHAPI FOOTHILLS. THERE IS A 30 TO 80
PERCENT CHANCE FOR GREATER THAN ONE TENTH OF AN INCH IN THESE
AREAS BY SATURDAY AFTERNOON.
* STRONG WIND GUSTS WILL CONTINUE ALONG THE MOJAVE SLOPES
THROUGH SATURDAY. A WIND ADVISORY REMAINS IN EFFECT FOR THIS
AREA DUE TO EXPECTED WINDS 30 TO 40 MPH WITH GUSTS TO 60 MPH.
* THERE IS POTENTIAL FOR A SYSTEM TO BRING MORE SIGNIFICANT
PRECIPITATION NEXT WEEK. BUT THERE REMAINS A LARGE AMOUNT OF
UNCERTAINTY WITH THE TRACK OF THIS SYSTEM AT THIS TIME.
DISCUSSION
A WEAK SHORTWAVE MOVING THROUGH THE MEAN FLOW TODAY WILL ALLOW
FOR SOME LIGHT PRECIPITATION, THOUGH THE MAIN IMPACT IS THE
WINDS ALONG THE LEE SLOPES OF THE KERN COUNTY MOUNTAINS. THE
BROADER TROUGH PARKED OFF THE PACIFIC NW COAST WILL CONTINUE BE
THE MAJOR PLAYER OVER THE NEXT WEEK.
THAT TROUGH WILL STEER THE ATMOSPHERIC RIVER STRETCHING ACROSS
THE PACIFIC, WITH THE LATEST GUIDANCE PUSHING IT FURTHER SOUTH.
THAT TRAJECTORY IS MORE FAVORABLE FOR PRECIPITATION ACROSS
CENTRAL CALIFORNIA, THOUGH WHERE IT COMES ONSHORE WILL DRIVE HOW
MUCH. WE WILL CONTINUE TO WATCH HOW IT SHAPES UP OVER THE
WEEKEND, BUT SOME PRECIPITATION IS EXPECTED EARLY NEXT WEEK.
