.DISCUSSION...
ONSHORE ZONAL FLOW OVER THE AREA WILL KEEP THE REGION CLEAR AND
DRY THROUGH WED WITH STEADY TEMPERATURES. DEEP UPPER LOW CENTER
IN THE GULF OF ALASKA WILL EJECT OUT A PIECE OF ENERGY SE INTO
NRN CA BY WED EVENING. THE ENERGY WILL CUT OFF AN UPPER LOW AND
CONTINUE TO MOVE SE OVER CEN CAL ON THURSDAY. THE CURRENT TRACK IS
A COASTAL HUGGER WITH BEST DIFLUENT ZONE ACROSS THE SOUTHERN
SIERRA THURSDAY AND CONTINUING THROUGH THE WEEKEND. THE UPPER LOW
CENTER STALLS OUT OVER KERN COUNTY ON SATURDAY AND THEN STARTS TO
LIFT NE LATE SAT INTO NV. CONTINUED UNSETTLED WEATHER IS EXPECTED
THROUGH SUNDAY BEFORE THE LOW CENTER LIFTS WELL NE OF THE FA BY
MONDAY. GUIDANCE IS STILL KEEPING A BAGGY TROUGH OVER THE REGION
AND ISOL SHRA/TSRA IS NOT OUT OF THE QUESTION MON AND TUES ACROSS
THE HIGH SIERRA.

THERE HAS BEEN SOME DISCUSSION OF THE POSSIBILITY OF TROPICAL
MOISTURE GETTING ENTRAINED INTO THE UPPER LOW OVER THE REGION THIS
WEEKEND. THE LATEST GUIDANCE IS BACKING OFF THIS SOLN AS NHC IS
FORECASTING ANDREAS TO REMAIN NEARLY STATIONARY AND RAPIDLY
WEAKENING. THE MOISTURE FIELD WILL REMAIN NEAR THE CENTER AS THE
HURRICANE RAPIDLY WEAKENS. ALSO WEAK RIDGING OVER THE TOP OF THE
CENTER WILL KEEP ANY SIGNIFICANT MOISTURE SHUNTED SOUTH. IT LOOKS
NOW LIKE THE UPPER LOW WILL ALSO NOT DIG FAR ENOUGH SOUTH TO BRING
ANY SIGNIFICANT MOISTURE FROM ANDREAS INTO THE AREA.

AS FAR A MOISTURE FROM BLANCA GOES...REMNANTS OF ANDREAS WILL HELP
DEVELOP A BAGGY TROUGH ACROSS THE WEST COAST BY TUESDAY AND KEEP
MOISTURE WELL EAST OF THE FA EARLY NEXT WEEK.
