AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SAN JOAQUIN VALLEY - HANFORD CA
934 PM PST SUN DEC 4 2011

.SYNOPSIS...
TONIGHT WILL BE ANOTHER NIGHT OF FREEZING TEMPERATURES IN THE
SAN JOAQUIN VALLEY. ALSO, A DRY TROUGH IS EXPECTED TO DROP INTO
THE REGION AND BRING WINDY CONDITIONS TO THE MOUNTAINS AND
DESERTS AS EARLY AS TONIGHT THROUGH MONDAY.

&&

.DISCUSSION...
ANOTHER CLEAR AND COLD EVENING IS UNDERWAY FOR THE CENTRAL
CALIFORNIA INTERIOR. TEMPERATURES ARE CURRENTLY RUNNING WITHIN A
DEGREE OR SO OF 24 HRS AGO AND FREEZING CONDITIONS SIMILAR TO LAST
NIGHT ARE EXPECTED AGAIN TONIGHT. AN UPPER LOW CURRENTLY NEARING
THE FOUR CORNERS REGION IS TAKING A MORE EASTERLY TRAJECTORY THAN
RECENT SYSTEMS AND SHOULD BRING BREEZY CONDITIONS OVER THE
MOUNTAINS BUT GENERALLY BELOW ADVISORY CRITERIA. IT WILL ALSO
BRING REINFORCING COOL AIR TO THE REGION AND THE GENERALLY CLEAR
AND COOL TREND WILL PERSIST FOR AT LEAST THE NEXT FEW DAYS. THE
FREEZE WARNING REMAINS IN EFFECT FOR THE SAN JOAQUIN VALLEY
TONIGHT AND NO UPDATE IS PLANNED FOR THE FORECAST THIS EVENING.

&&

.PREV DISCUSSION... /ISSUED 213 PM PST SUN DEC 4 2011/

DISCUSSION...THE SYNOPTIC PATTERN OVER THE WEST IS EXTREMELY
AMPLIFIED. THE RIDGE OVER THE PACIFIC EXTENDS INTO NORTHERN ALASKA
WITH A LARGE TROUGH IS IN THE CENTRAL U.S. THIS LEAVES CALIFORNIA
IN A NORTHERLY FLOW WITH COOL AIR FLOWING SOUTH FROM NORTHWEST
CANADA. EMBEDDED IN THIS FLOW IS THE NEXT VORTICITY CENTER WHICH
IS DROPPING SOUTH THROUGH THE GREAT BASIN THIS AFTERNOON AND WILL
CLOSE OFF AND BE NEAR THE 4 CORNERS REGION BY MONDAY MORNING. IT
CONTINUES TO LOOK LIKE THE LOW POSITION SHOULD BE FAR ENOUGH EAST
TO KEEP THE ASSOCIATED JET STREAM WINDS ORIENTED IN A NORTHERLY
DIRECTION RATHER THAN NORTHEAST WHICH IS RESPONSIBLE FOR A MONO
WIND EVENT. THERE WILL STILL BE SOME GUSTY WINDS...MOST LIKELY
OVER THE SIERRA CREST TONIGHT AND THEN EXTENDING DOWN INTO THE
MOUNTAINS AND DESERT OF KERN COUNTY MONDAY...ESPECIALLY IN THE
INDIAN WELLS VALLEY WHICH IS SUSCEPTIBLE TO THE GUSTY NORTHERLY
WINDS. HOWEVER AT THIS TIME IT LOOKS LIKE THE WINDS WILL REMAIN
BELOW ADVISORY CRITERIA.

THERE HAS NOT BEEN MUCH MODIFICATION OF THE AIRMASS OVER THE SAN
JOAQUIN VALLEY TODAY...AND WITH LITTLE IF ANY WIND IN THE VALLEY
TONIGHT IT LOOKS LIKE TEMPERATURES WILL BE AS COLD AS LAST NIGHT
THROUGHOUT MOST OF THE VALLEY. THIS MEANS WIDESPREAD FROST AS
TEMPERATURES DROP BELOW 32 DEGREES. COLDEST LOCATIONS WILL ONCE
AGAIN BE NEAR 25 OR 26 DEGREES FOR A FEW HOURS. THUS A FREEZE
WARNING HAS BEEN ISSUED FOR TONIGHT. WITH A REINFORCING SHOT OF
COLD AIR ON MONDAY IT LOOKS LIKE WE WILL BE DEALING WITH THE
FREEZING TEMPERATURES THROUGH AT LEAST WEDNESDAY NIGHT.

FOR THE EXTENDED FORECAST...THE RIDGE IS PROGGED TO REMAIN STRONG
OVER THE WEST FOR AT LEAST THE NEXT SEVERAL DAYS. THIS WILL KEEP
THE PATTERN DRY AND COOL THROUGH AT LEAST MID WEEK. BY THE END OF
THE WEEK...MODELS ARE TRYING TO BRING ANOTHER WEAK SYSTEM DOWN
INTO THE GREAT BASIN. BUT THE GFS AND ECMWF ARE IN DISAGREEMENT ON
THE PLACEMENT AND TIMING. EITHER SOLUTION LOOKS DRY FOR CENTRAL
CALIFORNIA.
