AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
1037 PM PST SUN DEC 23 2012

.SHORT TERM DISCUSSION...

UPPER TROUGH IS OVER THE STATE THIS EVENING AND WILL TRANSITION
INTO THE GREAT BASIN ON MONDAY. MOST OF THE PRECIP HAS SHIFTED
EAST OF THE AREA...ALTHOUGH STILL HAVE LINGERING SHOWERS OVER THE
SIERRA. HAVE ALLOWED THE WINTER STORM WARNING TO EXPIRE AT 10
PM...BUT STILL COULD SEE FEW MORE INCHES OF SNOW OVER THE SIERRA
TONIGHT ALTHOUGH THE HEAVIEST ACCUMULATIONS HAVE ALREADY FALLEN.
SNOW LEVELS ARE BETWEEN 4000-4500 FEET. TRAVEL WILL REMAIN
HAZARDOUS ON HIGHWAYS OVER THE SIERRA. HAVE ADDED FOG OVER THE
DELTA OVERNIGHT...EXPECTING THE LOW CLOUDS TO HANG IN OVER THE
VALLEY LIMITING FOG DEVELOPMENT. IF CLOUDS SCATTER OUT LATER
TONIGHT FOG WILL DEVELOP SO MID SHIFT WILL NEED NEED TO KEEP AN
EYE ON THIS. WINDS HAVE DIMINISHED THROUGHOUT THE AREA FROM THE
EARLIER STRONG SPEEDS AND WILL REMAIN RELATIVELY LIGHT OVERNIGHT.

PREVIOUS FORECAST...

THE BACK EDGE OF THE STEADY FRONTAL RAIN IS APPROACHING SACRAMENTO
AND WILL CONTINUE TO PUSH SOUTHWARD THIS EVENING WITH SHOWERS
LIKELY BEHIND THE FRONT FOR THE EVENING. THE WINDS LOOK LIKE THEY
WILL STAY UP FOR A FEW MORE HOURS THAN EARLY EXPECTED SO HAVE
EXTENDED THE WIND ADVISORY UNTIL 6 PM. THE SNOW ADVISORY FOR THE
BURNEY BASIN AND WINTER STORM WARNING FROM PLUMAS COUNTY NORTH
WILL BE CANCELLED AS SNOWFALL HAS DROPPED OFF AND ONLY MINOR
ACCUMULATIONS ARE POSSIBLE THROUGH THE EVENING.

SHOWERS WILL GRADUALLY TAPERING OFF OVERNIGHT. MONDAY CONTINUES TO
LOOK LIKE A DRY DAY WITH PERHAPS A FEW MORNING LINGERING SHOWERS
NEAR THE CREST.

THE WARM FRONTAL PART OF THE NEXT SYSTEM WILL BEGIN TO MOVE INTO
THE REGION MONDAY NIGHT AND TUESDAY AND MAINLY IMPACT MOUNTAIN AREAS
AND AREAS OVER THE NORTH END OF THE VALLEY WITH POSSIBLE LIGHT
AMOUNTS OF PRECIPITATION. THE COLD FRONT WILL MOVE INTO THE
INTERIOR CHRISTMAS NIGHT...FIRST EARLY IN THE EVENING OVER THE
NORTH AND THEN BY LATE EVENING FOR SACRAMENTO AND PLACES SOUTH.
SHOWERS WILL LINGER BEHIND THE SYSTEM FOR WEDNESDAY BEFORE
GRADUALLY TAPERING OFF WEDNESDAY NIGHT. THIS SYSTEM MAY BE ABLE TO
BRING ANOTHER FOOT OR SO OF SNOW TO THE HIGHER ELEVATIONS OF THE
SIERRA NEVADA. WINDS WILL BE MUCH LIGHTER THAN WHAT OCCURRED WITH
THE CURRENT SYSTEM WITH PERHAPS RAINFALL AMOUNTS BETWEEN A HALF
INCH TO AN INCH FOR THE VALLEY.

.EXTENDED DISCUSSION (THURSDAY THROUGH SUNDAY)

GENERAL MODEL CONCENSUS THAT THE WEST COAST WILL BE UNDER THE
INFLUENCE OF AN AMPLIFIED RIDGE IN THE LATTER HALF OF NEXT
WEEK. THE BRIEF WARMING AND DRYING TREND WILL BE THREATENED OVER
THE WEEKEND BY THE PRESENCE OF A LOW PRESSURE SYSTEM LINGERING
JUST OFFSHORE. MODEL SOLUTIONS DIVERGE PER THE DETAILS AND
TRAJECTORY OF THIS OFFSHORE LOW... WITH THE EC RIDING THE LOW
SOUTHWARD ALONG THE PAC COASTLINE AND THE GFS KEEPING THE REGION
RELATIVELY DRY AND THE LOW ABOUT A HUNDRED MILES OFF THE PACIFIC
COASTLINE. DECIDED TO NUDGE POPS TOWARDS THE DRIER SOLUTION BUT
LEFT A HINT OF CLIMO ON DAYS 7 AND 8. WEAK RIDGING REDEVELOPS A
WEEK FROM TOMORROW.

&&

.AVIATION...

STRONG LOW PRESSURE SYSTEM HAS MOVED THROUGH THE REGION...ALTHOUGH
ISOLATED VALLEY -SHRA AND WIDESPREAD SIERRA -SHSN CONTINUE.
IN THE VALLEY...ISOLATED -SHRA WILL DISSIPATE OVERNIGHT. WITH
ABUNDANT MOISTURE IN THE LOW LEVELS...EXPECT IFR/LIFR CIGS TO
REMAIN TRAPPED IN THE VALLEY THROUGH MIDDAY MONDAY. OVER THE
MOUNTAINS...IFR/LIFR -SHSN WILL GRADUALLY DISSIPATE AFTER 08Z MON.

SOUTHEAST WINDS 10-20 KT WITH LOCAL GUSTS UP TO 30 KT WILL BECOME
LESS THAN 10 KT...THEN BECOME NORTHWESTERLY ON MONDAY. DANG
