AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
1003 AM PST MON DEC 24 2012

.SHORT TERM DISCUSSION...

BREAK IN THE WET WX TODAY OVER INTERIOR NORCAL AS THE UPPER TROF HAS
PUSHED EAST AND THE MID TO UPPER LEVEL FLOW TRANSITIONS TO
ANTICYCLONIC TODAY. FIRST VISIBLE SAT IMAGES REVEAL SCATTERED CLOUDS
OVER THE SIERNEV WITH A DECK OF LOW CLOUDS IN THE CENTRAL VALLEY
FROM THE CHICO/OROVILLE AREA SWD TO STOCKTON. LOCAL VSBYS WITHIN THE
CLOUD DECK HAVE BEEN RESTRICTED BY DENSE FOG WITH THE ADVSRY RUNNING
INTO MID TO LATE MORNING. CLOUD TOPS ESTIMATED TO BE AROUND 1 KFT
AND GIVEN THE LOW SUN ANGLE...THE CLOUDS WILL BE SLOWER TO
DISSIPATE IN THE CENTER OF THE DECK ALONG THE SAC VLY...AND MAY
LINGER INTO THE AFTERNOON.

THE BULK OF THE ENERGY FROM THE NEXT SYSTEM IS FORECAST TO SPREAD
OVER THE SRN PORTION OF OUR FORECAST AREA TUE NITE. THE FORECAST
AREA WILL BE IN THE FAVORABLE LEFT EXIT REGION WHEN LARGE SCALE
ASCENT WILL BE MAXIMIZED RESULTING IN THE HEAVIEST PRECIP OVER THE
AREA DURING THIS TIME. 1000-850 MBS MOISTURE TRANSPORT VECTORS ARE
FORECAST TO BE WEAKEN AS THE SYSTEM MOVES INLAND AND BE WEAKER THAN
THE WEEKEND STORMS COMPARATIVELY. STILL MTN TRAVEL WILL BE MOST
DIFFICULT TUE NITE INTO WED MORNING.    JHM

.PREVIOUS DISCUSSION...

NEXT SYSTEM MOVES INTO NORCAL CHRISTMAS WITH PRECIP BEGINNING OVER
SHASTA COUNTY IN THE MORNING AND SPREADING SOUTH TO AROUND I-80 BY
LATE AFTERNOON. SATELLITE IMAGERY SHOWS ANOTHER POTENT SYSTEM
OFFSHORE...BUT IT WILL MOVE THROUGH QUICKLY WITH A RELATIVELY BRIEF
SHOT OF MODERATE TO HEAVY PRECIP AND GUSTY WINDS. ANOTHER 1/2 TO 1
INCH OF RAIN WILL BE POSSIBLE IN THE VALLEY WITH A FOOT OR TWO OF
SNOW POSSIBLE ALONG THE CREST OF THE NORTHERN SIERRA. WINTER STORM
WATCHES HAVE BEEN POSTED FOR THE MOUNTAINS.

THE FRONT MOVES SOUTH OF THE REGION CHRISTMAS NIGHT WITH SHOWERS
LINGERING INTO WEDNESDAY AS THE UPPER TROUGH REMAINS OVERHEAD.
TROUGH BEGINS TO SHIFT EAST THURSDAY RESULTING IN DRIER NORTHERLY
FLOW FOR MUCH OF THE REGION...BUT A CHANCE OF LINGERING SHOWERS
FOR THE NORTHERN SIERRA.

.EXTENDED DISCUSSION (FRIDAY THROUGH MONDAY)

GENERAL MODEL CONSENSUS IS THAT THE WEST COAST WILL BE UNDER THE
INFLUENCE OF AN AMPLIFIED RIDGE FRIDAY. THEN A LOW PRESSURE SYSTEM
SPLITS FROM THE MAIN JET FLOW AND DESCENDS SOUTHWARD AND LINGERS
JUST OFFSHORE. MODEL SOLUTIONS DIVERGE PER THE DETAILS AND
TRAJECTORY OF THIS OFFSHORE LOW. THE GFS AND GEM PLACES THE LOW
AROUND 125W WITH A CHANCE OF SHOWERY ACTIVITY OVER THE AREA ON
SATURDAY WHILE THE EC KEEPS THE REGION RELATIVELY DRY AND THE LOW
FARTHER WEST NEAR 130W. ALL IN ALL...NOT MUCH DIFFERENCE IN THE
MODELS WITH THIS TYPE OF PATTERN THIS FAR OUT. DECIDED TO NUDGE
POPS TOWARDS THE DRIER SOLUTION BUT LEFT A HINT OF CLIMO ON
SATURDAY (DAY 6). SUNDAY AND MONDAY HAVE THE LOW DRIFTING SOUTH
OVER THE ERN PAC WITH A REX BLOCK HIGH SETTING UP OVER THE WEST
COAST. THEREFORE...KEPT THE REGION DRY SUNDAY AND MONDAY (DAYS 7
AND 8).    JCLAPP

&&

.AVIATION...

ABUNDANT MOISTURE AND MAINLY CLEAR SKIES HAVE PRODUCED FOG OVER
THE SOUTHERN HALF OF THE SACRAMENTO VALLEY...DELTA AND FROM NEAR
PARADISE SOUTHWARD IN THE FOOTHILLS THIS MORNING. VSBYS WILL IMPROVE
BETWEEN 18Z AND 19Z AS THE FOG LIFTS INTO A STRATUS DECK. AREAS
OF MVFR CONDITIONS FROM THE STATUS MAY PERSIST THROUGH 22Z. WIDELY
SCT MVFR CIGS OVER THE MOUNTAINS TODAY.

A CHANCE THAT SOME MVFR CONDITIONS IN BR WILL FORM AFTER 04Z FROM
AROUND OROVILLE SOUTHWARD...WITH LOCAL DENSE FOG POSSIBLY FORMING
AFT 10Z. SOME MID TO HIGH CLOUDS MOVING INTO THE REGION LATER
TONIGHT MAY HELP TO PREVENT ANY DENSE FOG FROM FORMING.
