AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
445 PM PST FRI NOV 30 2012

.SHORT TERM DISCUSSION...

WATER VAPOR IMAGERY SHOWS THE UPPER LEVEL LOW WHICH HAS BROUGHT
SIGNIFICANT RAIN TO THE AREA CONTINUES TO BE LOCATED OFF THE
COAST. THE SHORTWAVE AND COLD FRONT WHICH BROUGHT A BROAD BAND OF
PRECIPITATION EARLIER TODAY ARE EXITING THE REGION. THE PACIFIC
MOISTURE PLUME WHICH HAS BEEN FEEDING THIS SYSTEM HAS SLID
SOUTHWARD. IN THE WAKE OF THIS SYSTEM THERE IS MORE SHOWERY
PRECIPITATION AND BROKEN CLOUD COVER.

CURRENT RADAR SHOWS PRECIPITATION MAINLY OVER THE MOUNTAINS.
THERE HAVE BEEN NUMEROUS REPORTS OF PONDING OF WATER ON AREA
ROADS...CAR ACCIDENTS IN SLIPPERY CONDITIONS...AND SOME ROCKS DOWN
ON FOOTHILL/MOUNTAIN ROADS. OROGRAPHIC LIFT HAS BROUGHT IMPRESSIVE
24 HOUR RAINFALL TOTALS TO THE AREA. THE FACT THAT IT IS STILL
FALL AND THERE IS QUITE A BIT OF ROOM FOR AREA RESERVOIRS TO FILL
IS A MAJOR REASON WHY THIS EVENT IS NOT CAUSING LARGE SCALE
FLOODING.

SEVERAL INCHES OF SNOW FELL ON INTERSTATE 80 AT DONNER PASS AS
HEAVIER SHOWERS PASSED THROUGH THIS AFTERNOON DROPPING SNOW LEVELS
DOWN TO AROUND 7000 FEET. WEBCAMS AND REPORTS SHOW THIS HAS
LARGELY ENDED. SNOW LEVELS MAY DROP SOME OVERNIGHT BUT LITTLE
ACCUMULATION IS EXPECTED. HIGHER SNOW LEVELS ARE ANTICIPATED FOR
SATURDAY AND EARLY SUNDAY LIMITING SNOWFALL TO HIGHER ELEVATIONS.

INSTABILITY BEHIND THE FRONT OVER THE NORTHERN PORTION OF THE
FORECAST AREA THIS AFTERNOON WAS LIMITED BY A LACK OF COLD AIR
ALOFT AND THE SHORT PERIOD OF DAYLIGHT THIS TIME OF YEAR.
THUNDERSTORMS THAT FORMED WERE GENERALLY ISOLATED AND RELATIVELY
WEAK.

ANOTHER SYSTEM ARRIVES EARLY SATURDAY BRINGING MORE RAIN TO THE AREA.
THIS LOOKS LIKE A WEAKER SYSTEM THAN WE SAW TODAY. THE MUCH MORE
IMPRESSIVE SYSTEM ARRIVES SATURDAY NIGHT INTO SUNDAY MORNING. THIS
HAS A WIDE PLUME OF MOISTURE AND GOOD DYNAMICS TO BRING THE
HEAVIEST AMOUNT OF PRECIPITATION SEEN WITH THE RECENT SERIES OF
STORMS. SEVERAL LOCATIONS IN THE UPPER SACRAMENTO RIVER ARE LIKELY
TO REACH AND EXCEED FLOOD LEVEL. SMALLER STREAMS...ESPECIALLY OVER
THE NORTHERN PORTION OF THE FORECAST AREA ARE ALSO LIKELY TO
FLOOD. DEBRIS FLOWS NEAR BURN AREAS REMAINS A POSSIBILITY. A FLOOD
WATCH CONTINUES THROUGH MONDAY AFTERNOON.

WIND IS ANOTHER ISSUE AND WINDY CONDITIONS WILL CONTINUE THROUGH
SUNDAY. A WIND ADVISORY CONTINUES INTO SUNDAY. WHEN COUPLED WITH
SOAKED GROUND THE WIND COULD CAUSE TREES TO UPROOT. FALLING TREES
AND BRANCHES MAY CAUSE LOCAL POWER OUTAGES. THE STRONGEST WINDS
ARE EXPECTED SATURDAY NIGHT INTO EARLY SUNDAY WHEN THE SURFACE
GRADIENT BETWEEN MEDFORD AND SACRAMENTO REACHES AROUND 15 MB.
WINDS GUSTING TO 50 MPH IN THE VALLEY ARE POSSIBLE THEN...WITH
GUSTS TO 70 MPH IN THE MOUNTAINS.

DRIER WEATHER ARRIVES ON MONDAY AS WEAK RIDGING MOVES INTO THE
AREA. EK

.EXTENDED DISCUSSION (TUESDAY THROUGH FRIDAY)

ANOTHER DEEP MOISTURE PLUME WILL DEVELOP OVER THE EASTERN PACIFIC
AS UPPER LOW DROPS SOUTH FROM THE GULF OF ALASKA. THIS LOW WILL
DEEPEN THE TROUGH AND PUSH DEEP MOISTURE INTO NORTHERN CALIFORNIA
ON TUESDAY. WILL KEEP HIGH END CHANCE TO LIKELY POPS DURING THIS
PERIOD SINCE MODELS CONTINUE TO SHOW GOOD AGREEMENT FOR THIS
UPCOMING PATTERN. SHOWER CHANCES CONTINUE ON WEDNESDAY AS TROUGH
MOVES THROUGH WITH LINGERING MOISTURE AND INSTABILITY...ALTHOUGH
MOISTURE VALUES ARE LOWER VERSUS TUESDAY. A DRIER NORTHWEST FLOW
IS THEN PROGGED TO DEVELOP INTO THE WEEKEND AS RIDGE DEVELOPS OVER
THE PACIFIC. AT THIS TIME THE ECMWF AND GFS ARE IN VERY GOOD
AGREEMENT THROUGH THE EXTENDED.

&&

.AVIATION...

SHOWERS WILL CONTINUE ACROSS INTERIOR NORCAL TONIGHT INTO TOMORROW
AS THE AREA LIES BETWEEN TWO WEATHER SYSTEMS. SAC VALLEY TAF SITES
WILL SEE INTERMITTENT MFVR OR EVEN IFR CEILINGS OVERNIGHT WITH
ISOLATED TO SCATTERED SHOWERS...WITH THE BETTER CHANCE OF MVFR OVER
THE NORTHERN SAC VALLEY. WINDS WILL DECREASE A BIT BY THIS EVENING
WITH SUSTAINED WINDS RANGING 10-20 KTS AND GUSTS UP TO 30 KTS. A
LULL IS EXPECTED SATURDAY AFTERNOON BEFORE CLOUDS INCREASE AND
ANOTHER SYSTEM MOVES IN BY SUNDAY.

IN THE FOOTHILLS AND MOUNTAINS...WIDESPREAD IFR/LIFR CONTINUES
OVERNIGHT WITH PERSISTENT SHOWERS CAUSING LOW CIGS ALONG WITH
SOME WINDY CONDITIONS. SNOW LEVELS ABOUT 6500 FEET AND HIGHER. -DVC
