AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA
901 PM PDT THU MAR 18 2010
.SYNOPSIS...
A RIDGE OF HIGH PRESSURE ALONG WITH ABOVE NORMAL TEMPERATURES AND
DRY CONDITIONS WILL PREVAIL THROUGH THE WEEK.
&&
.DISCUSSION...
A MOISTURE STARVED SHORTWAVE DROPPED SOUTHWARD EAST OF THE SIERRA
CREST EARLIER TODAY. THIS BROUGHT INCREASED WINDS TO OUR AREA AS A
RESULT OF POST FRONTAL SUBSIDENCE AND A FEW CLOUDS TO THE MOUNTAINS.
HOWEVER...THE ANTICIPATED CONVECTION TODAY NEVER REACHED IT/S
ADVERTISED POTENTIAL AS A RESULT OF A VERY DRY AIRMASS AND A
STRONG MID LEVEL CAPPING INVERSION. OTHER THAN ONE ROGUE SHOWER
THAT MOVED OVER RIDGECREST EARLIER THIS EVENING...THERE WERE NO
REPORTS OF PRECIPITATION ANYWHERE IN OUR CWFA. IN FACT...EXCEPT
OVER THE SIERRA CREST IN TULARE COUNTY AND OVER THE INDIAN WELLS
VALLEY...SKIES ARE MAINLY CLEAR ACROSS OUR AREA AND CLEAR SKIES
ARE EXPECTED OVERNIGHT AS THE SHORTWAVE WHICH IS NOW CENTERED
NEAR LAS VEGAS...CONTINUES TO DROP SOUTHEAST AND PULL IT/S ENERGY
AWAY FROM OUR AREA. TEMPERATURES ARE GENERALLY RUNNING 2-4 DEG F
BELOW YDAY AT THIS TIME BUT INCREASED WINDS WILL LIKELY KEEP
TEMPERATURES FROM BOTTOMING OUT TONIGHT. AT THIS TIME THE FORECAST
FOR TONIGHT APPEARS TO BE IN GOOD SHAPE SO AM NOT PLANNING TO
UPDATE THIS EVENING.
00Z WRF/GFS INDICATE THE DRY UPPER RIDGE THAT PROVIDED THE WARM
AND DRY WEATHER FOR MUCH OF OUR AREA OVER THE PAST FEW DAYS WILL
REBUILD INTO CA FRIDAY AND FRIDAY NIGHT AND KEEP OUR AREA DRY WITH
MOSTLY CLEAR SKIES THROUGH AT LEAST THE EARLY PORTION OF NEXT
WEEK. HEIGHTS AND DIURNAL THICKNESSES WILL REBOUND ENOUGH BY
SATURDAY TO PUSH TEMPERATURES ABOVE SEASONAL NORMALS FOR LATE
MARCH THROUGH MONDAY.
THE MEDIUM RANGE MODELS CONTINUE TO INDICATE ANOTHER MOISTURE
STARVED INSIDE SLIDER TYPE SYSTEM DROPPING SOUTHWARD THROUGH THE
GREAT BASIN ON TUESDAY WHICH WOULD BRING A BRIEF PERIOD OF
INCREASED WINDS AND LOWER TEMPERATURES TO NEAR SEASONAL NORMALS
FOR THE MIDDLE PORTION OF NEXT WEEK.
&&
.AVIATION...
THE COMBINATION OF AN UPPER LEVEL DISTURBANCE AND STRONG HIGH
PRESSURE IN THE GREAT BASIN WILL PROVIDE MODERATE OFFSHORE WINDS
THROUGH FRIDAY MORNING. STRONG GUSTY NE WINDS WILL AFFECT
HIGHER ELEVATIONS OF THE SIERRA AND EAST TO WEST ORIENTED CANYONS OF
THE SIERRA THROUGH 15Z FRIDAY. OTHERWISE...VFR CONDITIONS WILL
PREVAIL ACROSS THE CENTRAL CALIFORNIA INTERIOR THROUGH 06Z
SATURDAY.
