AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
955 AM PST FRI NOV 9 2012

.SHORT TERM DISCUSSION...

UPPER LEVEL LOW IS CURRENTLY SITUATED NEAR THE SAN FRANCISCO BAY
AREA AND IS TRAVERSING SOUTHEASTWARD. THIS SYSTEM CONTINUES TO
BRING SCATTERED RAIN AND SNOW SHOWERS ACROSS THE FORECAST AREA...
WITH THE MAIN BANDS NOW ALONG THE SIERRA NEVADA. PRECIPITATION
REPORTS HAVE GENERALLY REMAINED BELOW 0.25 INCH ACROSS THE
VALLEY...WITH HIGHER AMOUNTS ALONG THE SIERRA. BASED ON SURFACE
REPORTS...SNOW LEVELS APPEAR TO BE AROUND 2000 FT IN SHASTA
COUNTY. A RAIN/SNOW MIX HAS BEEN REPORTED DOWN TO BETWEEN 2000 AND
2500 FT ALONG THE SIERRA FOOTHILLS.

UPPER TROUGH AXIS WILL ROTATE TO THE EAST INTO NEVADA TODAY.
HOWEVER WITH THE COLD POOL ALOFT STILL IN PLACE...SCATTERED
SHOWERS WILL LIKELY CONTINUE ACROSS THE FORECAST AREA TODAY INTO
TONIGHT. THE HIGHER RESOLUTION NAM AND WRF MODELS ARE SHOWING
AREAS OF ENHANCED INSTABILITY ALONG THE SIERRA THIS AFTERNOON.
GIVEN THIS CONVECTIVE NATURE AND LOW SNOW LEVELS...THE MOUNTAINS
COULD SEE ANOTHER ROUND OF HIGH SNOW-RATIO ACCUMULATION THROUGH
TONIGHT...AND MAY POSSIBLY MIX WITH ICE PELLETS AT TIMES. WE HAVE
EXTENDED THE SNOW ADVISORY ABOVE 3000 FT AS A RESULT.

SHOWERS SHOULD BE ON THE DECLINE TONIGHT ACROSS MOST OF THE
FORECAST AREA TONIGHT AS SUBSIDENCE INCREASES ON THE BACKSIDE OF
THE TROUGH. SNOW SHOWERS COULD CONTINUE ALONG THE HIGHER SIERRA
THROUGH SATURDAY AFTERNOON.

NEXT FORECAST CONCERN WILL BE POSSIBLE LOW ELEVATION FROST
SATURDAY AND SUNDAY MORNINGS. AT THIS JUNCTURE...IT LOOKS LIKE
ENOUGH CLOUD COVER WILL REMAIN IN PLACE SATURDAY MORNING TO KEEP
SURFACE TEMPS ABOVE FREEZING. SUNDAY MORNING MAY BE A DIFFERENT
STORY HOWEVER...AS SKIES WILL START OFF CLEAR WITH LIGHT WINDS.
THERE DOES APPEAR TO BE ANOTHER BATCH OF CLOUD COVER MOVING IN
AROUND SUNRISE SUNDAY...BUT MAY NOT GREATLY IMPACT OVERNIGHT LOWS.
GUIDANCE SUGGESTS LOWS COULD REACH THE UPPER 20S TO MID 30S ACROSS
THE SACRAMENTO VALLEY...AND IN THE MID TO UPPER 20S ALONG THE
SIERRA FOOTHILLS. THIS WOULD BE SUPPORTIVE OF AT LEAST PATCHY
FROST ACROSS MUCH OF THE REGION.

WESTERLY FLOW ALOFT WILL REMAIN OVER THE REGION SUNDAY INTO
MONDAY. A WEAK SHORTWAVE WILL PASS THROUGH THE PACIFIC NORTHWEST
IN THIS TIMEFRAME...BUT AT THIS JUNCTURE IT LOOKS LIKE THE MAIN
IMPACTS WILL REMAIN TO OUR NORTH. DANG

.EXTENDED DISCUSSION (TUESDAY THROUGH FRIDAY)

EXTENDED MODELS ALL SEEM TO WANT TO SPLIT THIS NEXT SYSTEM AS IT
PUSHES ONTO THE COAST WHICH SLOWS ITS PROGRESS EASTWARD. WITH THE
UPPER TROUGH IN VICINITY OF THE COAST...GENERAL SHOWER THREAT MUST
CONTINUE INTO THE MIDDLE OF NEXT WEEK. TIMING AND POSITIONING
DIFFERENCES CONTINUE WITH THE EXTENDED MODELS AND HOW THEY HANDLE
THE SPLITTING TROUGH SO CONFIDENCE IN EXTENDED FORECAST IS LOW
ESPECIALLY BY THE END OF NEXT WEEK WHEN SIGNIFICANT DIFFERENCES IN
THE MODELS DEVELOP OVER THE WEST COAST. WHATEVER THE
OUTCOME...COOLER THAN NORMAL DAYTIME TEMPERATURES APPEAR TO REMAIN
THE RULE THROUGH THE EXTENDED PERIOD.

&&

.AVIATION...

SCATTERED SHOWER ACTIVITY CONTINUES ACROSS NORCAL
TODAY...PARTICULARLY OVER THE HIGHER ELEVATIONS. ANOTHER IMPULSE
MOVING THROUGH THIS AFTERNOON WILL LEAD TO INCREASED SHOWER
ACTIVITY OVER THE CENTRAL VALLEY LATER TODAY. EXPECT PERIODS OF
LOCAL MVFR CONDITIONS IN THE VALLEY DURING SHOWERS AND/OR
ISOLATED THUNDERSTORMS...OTHERWISE VFR CONDITIONS PREVAIL WITH
CLEARING SKIES OVERNIGHT. FOR THE MOUNTAINS...VFR/MVFR CONDITIONS
TODAY INTO TONIGHT WITH PERIODS OF IFR/LIFR DURING SNOW SHOWERS.
SNOW LEVELS WILL BE AS LOW AS 2500FT. WINDS WILL GENERALLY BE
LIGHT...UNDER 10KTS MOST LOCATIONS. -DVC
