Severe Thunderstorm Warning 9, NWS Hanford, CA

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HANFORD CA
250 PM PST TUE FEB 22 2005

.SHORT TERM...FOR THE CENTRAL CALIFORNIA INTERIOR...THE PESKY UPPER
LOW RESPONSIBLE FOR THE INCLEMENT WEATHER OF THE PAST WEEK REMAINS
JUST OFFSHORE OF POINT CONCEPTION. THIS LOW WILL TRACK EAST THROUGH
SOCAL OVERNIGHT INTO TOMORROW, BUT WILL BE CLOSE ENOUGH TO WARRANT A
CONTINUATION OF POPS FOR ALL ZONES THROUGH TOMORROW EVENING.
ALTHOUGH THUNDER HAS BEEN A DIFFICULT COMMODITY TO ATTAIN THUS FAR
IN THE VALLEY, WILL KEEP A MENTION OF IT FOR ALL ZONES THIS EVENING.
IN ADDITION, WILL ADD THUNDER FOR TOMORROW AFTERNOON AND EVENING DUE
TO THE LINGERING UNSTABLE AIRMASS. WITH THE LOW MOVING EAST OF THE
COLORADO RIVER LATE WEDNESDAY NIGHT INTO THURSDAY, HAVE DRIED OUT
THE VALLEY, BUT THE LOWS PRESENCE WILL PROBABLY CONTINUE TO
GENERATE ISOLATED SHOWERS OVER THE MOUNTAINS AND DESERTS THROUGH
THIS PERIOD. WOULD EXPECT FRIDAY TO BE DRY FOR ALMOST ALL AREAS, BUT
THE GFS DOES HINT AT SOME LINGERING VORTICITY DROPPING ALONG THE
CREST DURING THE DAY ON THE CYCLONIC FLOW. WOULD NOT BE SURPRISED TO
SEE UPSLOPE SHOWERS DEVELOP EAST OF THE CREST AND WOBBLE OVER ONTO
OUR SIDE GIVEN THE FLOW ALOFT, BUT WILL KEEP SILENT POPS IN THE
GRIDS AT 10 PERCENT OR LESS FOR NOW.

.LONG TERM...FOR FRIDAY NIGHT THROUGH TUESDAY...GENERAL CONSENSUS OF
MEDIUM RANGE MODELS IS TO BRING A WEAKENING SHORTWAVE TROUGH ACROSS
CENTRAL CALIFORNIA BY FRIDAY NIGHT...FOLLOWED BY A RIDGE AMPLIFYING
OVER THE REGION THROUGH SUNDAY...AHEAD OF THE NEXT APPROACHING LOW
PRESSURE SYSTEM. THE WEAKENING TROUGH FRIDAY NIGHT IS NOT EXPECTED TO
PRODUCE ANY PRECIPITATION OVER OUR AREA AT THIS TIME. FAIR AND
SEASONABLY MILD CONDITIONS SHOULD PREVAIL THROUGH SUNDAY UNDER THE
HIGH PRESSURE RIDGE...WITH JUST SOME PATCHY FOG DEVELOPING IN THE
VALLEY EACH NIGHT AND MORNING. WITH UNCERTAINTY IN TIMING AND
EVOLUTION OF THE NEXT APPROACHING SYSTEM...THE FORECAST SHOWS
SOMEWHAT BROAD BRUSHED SLIGHT CHANCE TO CHANCE POPS BY SUNDAY
NIGHT...CONTINUING INTO MIDWEEK...AS THE UPPER LOW SLIPS GRADUALLY
TOWARD NORTHWEST MEXICO. TEMPERATURES ARE EXPECTED TO REMAIN NEAR
CLIMO THROUGH THE PERIOD.
