PROGS HAVE THE UPPER LOW NOW OFF THE NORTHERN CA COAST MOVING SSE
TONIGHT...CROSSING THE SIERRA A LITTLE SOUTH OF MONO COUNTY AROUND
SUNRISE SATURDAY AND ENDING UP NEAR THE SOUTHERN TIP OF NV SATURDAY
AFTERNOON.  THE 18Z ETA DEVELOPS MORE QPF ON THE EAST SIDE OF THE
SIERRA AS THE FLOW COMES AROUND TO THE NORTHEAST THAN THE 12Z RUN DID.
THIS IS MORE IN LINE WITH THE AVN AND IS SIMILAR TO OUR LOCAL MM5 RUN.
WILL KEEP THE WINTER STORM WARNINGS IN EFFECT WITH SOME ADJUSTMENT TO
THEIR ENDING TIMES EXCEPT IT LOOKS LIKE THE SNOW WILL CUT OFF TOO SOON
IN ZONE 71 FOR THE WARNING TO VERIFY.  SNOW LEVELS SHOULD REACH THE
LOWER VALLEY FLOORS IN MOST OF NW NV TONIGHT BUT ACCUMULATIONS WILL
PROBABLY BE LIMITED TO UNPAVED SURFACES.

PROGS SHOW A WEAK FEATURE DROPPING SOUTH OVER NW NV DURING THE DAY
SATURDAY THAT TRIGGERS SOME LIGHT SHOWERS.  AFTER THAT A RIDGE STARTS
TO BUILD THAT WILL BRING DRY WEATHER AND A WARMING TREND THROUGH THE
MIDDLE OF NEXT WEEK.  THE MRF BRINGS A NEW TROUGH TOWARDS CA FASTER
THAN OTHER MODELS AFTER WEDNESDAY.  EXTENDED FORECFAST WILL CALL FOR A
LITTLE COOLING BUT NOT BRING ANY PRECIPITATION.   COREY

.REV...WINTER STORM WARNING THROUGH TONIGHT ZONE 2/72.
