AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
907 AM PDT SUN APR 7 2013

.DISCUSSION...
RELATIVE LULL IN THE WX ACROSS INTERIOR NORCAL THIS MORNING AS
WE/RE IN BETWEEN SYSTEMS. COLD FRONT ENTERS NORCAL LATER THIS
AFTERNOON AND SWEEPS SOUTHWARD OVERNIGHT. MUCH OF THE QPF IS
FORECAST OVER THE MOUNTAINS WHILE MOST VALLEY AMOUNTS WILL BE
LIGHT (WELL UNDER 1/4 INCH). APPEARS THERE IS SOME POTENTIAL FOR A
QUICK SHOT OF HEAVY SNOW ACROSS THE NORTHERN SIERRA OVERNIGHT
TONIGHT AND WILL EVALUATE FURTHER FOR AFTERNOON FORECAST PACKAGE.

GUSTY NORTHERLY FLOW DEVELOPS IN THE SYSTEM/S WAKE ON MONDAY AS
STRONG UPPER JET ALIGNS OVER THE AREA AND COLD ADVECTION AND
SUBSIDENCE INCREASE.

&&

.PREVIOUS DISCUSSION...
A LONG FETCH OF WESTERLY FLOW OVER THE EASTERN PACIFIC CONTINUES
TO BRING WEAK DISTURBANCES THROUGH NORTHERN CALIFORNIA THIS
MORNING. ONE OF THESE WEAK WAVES IS CURRENTLY BRINGING SOME VERY
LIGHT SHOWERS OVER PLUMAS COUNTY. SUBSEQUENT WEAK DISTURBANCES
WILL BRING A CONTINUED THREAT OF LIGHT PRECIPITATION TO SHASTA
COUNTY AND PORTIONS OF THE SIERRA CASCADE RANGE THROUGH THE DAY
TODAY. THE REMAINDER OF THE FORECAST AREA SHOULD SEE A MIX OF
CLOUDS AND SUN. THE OVERALL AIRMASS ONLY COOLS SLIGHTLY TODAY SO
SHOULD SEE DAYTIME HIGHS SIMILAR TO YESTERDAY. A SLIGHTLY STRONGER
DISTURBANCE NOW INSIDE 140 WEST IS FORECAST TO PIVOT INTO THE
NORTH COAST BY LATE THIS AFTERNOON THEN DIG SOUTHWARD DURING THE
NIGHT. MODELS VARY ON HOW MUCH MOISTURE THIS SYSTEM WILL CONTAIN.
EVEN WETTER SOLUTIONS GENERALLY LIMIT PRECIPITATION TO A FEW
TENTHS OF AN INCH OVER THE MOUNTAINS AND A FEW HUNDREDTHS OVER THE
VALLEY. BREEZY WINDS WILL ACCOMPANY THIS SYSTEM AND COMBINED WITH
THE LIGHT SNOWFALL COULD CAUSE MINOR TRAVEL DIFFICULTIES OVER THE
HIGHER ELEVATIONS. BY 12Z MONDAY...THE UPPER TROUGH AXIS SHIFTS
INTO THE GREAT BASIN LEAVING NORCAL UNDER INCREASING NORTHERLY
FLOW. CWA SHOULD SEE A RAPID DROP OFF IN PRECIPITATION AS THE
NORTHERLY FLOW BECOMES ESTABLISHED. SURFACE HIGH PRESSURE PUSHING
IN BEHIND TONIGHTS SYSTEM WILL BRING A TIGHTENING NORTHERLY
GRADIENT MONDAY EVENING WITH MODELS PREDICTING ABOUT AN 8 MB
GRADIENT FROM MFR TO SAC MONDAY EVENING THROUGH TUESDAY MORNING.
DECOUPLING WILL MAKE WINDSPEED PREDICTION DIFFICULT DURING THE
NIGHT AND EARLY MORNING HOURS TUESDAY BUT COULD SEE SOME PERIODS
OF WIND HITTING ADVISORY CRITERIA DURING THIS TIME.

PRESSURE GRADIENTS WEAKEN A BIT TUESDAY AFTERNOON AS UPPER RIDGE
AXIS EDGES TOWARDS THE WEST COAST. THE AIRMASS WARMS SIGNIFICANTLY
ON TUESDAY WITH DAYTIME HIGHS PUSHING TO AS MUCH AS 10 DEGREES
ABOVE NORMAL. STILL MORE WARMING IS ANTICIPATED ON WEDNESDAY AS
UPPER RIDGING BECOMES MORE ESTABLISHED AND THE NORTHERLY WINDS
SUBSIDE. MUCH OF THE CENTRAL VALLEY WILL LIKELY SEE HIGHS
WEDNESDAY IN THE 80S.

&&

.EXTENDED DISCUSSION (THURSDAY THROUGH SUNDAY)...
HIGH PRESSURE CELL OVER THE EASTERN PACIFIC AND THE WEST COAST
WILL LEAVE MOST OF OUR CWA WITH DRY AND MILD WEATHER FROM THURSDAY
INTO THE WEEKEND. HOWEVER...WEAK WAVES RIDING OVER THE HIGH
PRESSURE CELL COULD SKIRT NORCAL AND BRING A SLIGHT CHANCE OF
SHOWERS TO HIGHER TERRAIN ON SATURDAY AND SUNDAY OF NEXT
WEEK...ESPECIALLY THE COASTAL RANGE AND MOUNTAINS OF SHASTA
COUNTY. DAYTIME HIGHS ON THURSDAY WILL STILL BE UP TO 10 DEGREES
ABOVE NORMAL (VALLEY HIGHS IN THE UPPER 70S AND LOW 80S). FOR
FRIDAY INTO THE WEEKEND...DAYTIME HIGHS WILL GRADUALLY TREND
DOWNWARD UNTIL THEY ARE ONLY A COUPLE OF DEGREES ABOVE NORMAL ON
SUNDAY (VALLEY HIGHS IN THE MID 70S).

&&

.AVIATION...
OVERALL VFR CONDITIONS OVER INTERIOR NORCAL TAF SITES. A WEAK
WEATHER SYSTEM MOVING THROUGH TODAY/TONIGHT WILL BRING ISOLATED
MVFR SHWRS TO THE CENTRAL VALLEY. BEST CHANCE OF AFTERNOON/EVENING
SHOWERS AND LOCAL MVFR IN THE CENTRAL VALLEY WILL BE IN THE
KRDD-KRBL VICINITY. MEANWHILE...SOUTHERLY/SOUTHWESTERLY WINDS AT
VALLEY TAF SITES WILL INCREASE TO 10-20KTS BY THIS AFTERNOON AS
THE SYSTEM APPROACHES. WINS SHOULD DIE OFF OVERNIGHT BEFORE
TURNING TO THE NORTH TOMORROW AND INCREASING TO SUSTAINED 20-25
KTS MONDAY AFTERNOON.

SHOWERS OVER MOUNTAINS WILL PRODUCE A MIX OF MVFR/IFR/LIFR
CONDITIONS THROUGH MONDAY MORNING. SNOW LEVELS WILL LOWER TO
AROUND 3500 FEET BY MONDAY MORNING. -DVC

.STO WATCHES/WARNINGS/ADVISORIES...NONE.
