AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
910 AM PST SAT DEC 22 2012

.SHORT TERM DISCUSSION...

LOW PRESSURE AREA IS SLOWLY BECOMING MORE NEGATIVELY TILTED THIS
MORNING AS IT MOVES OVER THE INTERIOR. THE COLD FRONT IS MOVING
THROUGH THE SOUTHERN SACRAMENTO COUNTY AND SAN JOAQUIN VALLEY AND
EXTENDS NORTHEAST INTO THE MOUNTAINS. SOME HEAVY SNOW IS NOW
MOVING INTO THE SIERRA NEVADA WITH LOWERING SNOW LEVELS. SNOW
LEVELS MIGHT BE ABLE TO LOWER ENOUGH TO GET INTO THE UPPER
ELEVATIONS OF THE FOOTHILLS LATER THIS MORNING AND AFTERNOON SO
WILL BE KEEPING CLOSE TABS ON THAT TODAY. THE OTHER CONCERN FOR
TODAY WILL BE WITH THE POST FRONTAL SHOWER ACTIVITY WHICH COULD BE
HEAVY AT TIMES WITH POSSIBLE THUNDERSTORMS AND HAIL.

THE NEXT SYSTEM WILL MOVE INTO THE REGION LATE TONIGHT AND SUNDAY
MORNING AND LOOKS LIKE IT WILL HAVE STRONG WINDS ASSOCIATED WITH
IT SO WILL LIKELY BE POSTING A WIND ADVISORY WITH THE AFTERNOON
PACKAGE FOR THAT SYSTEM. THE CURRENT WINTER STORM WARNINGS THROUGH
SUNDAY LOOK GOOD. THUNDERSTORMS LOOK TO BE OF CONTINUED CONCERN
FOR SUNDAY WITH GREATER INSTABILITY AND WIND SHEER EXPECTED.

.EXTENDED DISCUSSION (WEDNESDAY THROUGH SATURDAY)

UNSETTLED WX CONTINUES THROUGH MID-WEEK ACROSS NORCAL AS ANOTHER
COLD UPPER LOW DROPS SOUTHWARD FROM THE GOA TO OFF THE PACNW
COAST. MODEL CONFIDENCE REMAINS QUITE HIGH WITH THIS INITIAL
SYSTEM AND INDICATES A FRONTAL SYSTEM MOVING THROUGH THE REGION
EARLY WEDNESDAY FOLLOWED BY POST-FRONTAL SHOWERS. DRIER
NORTHWESTERLY FLOW DEVELOPS LATER WEDNESDAY AND CONTINUES INTO
THURSDAY AS SHORT-WAVE RIDGING BUILDS INTO THE REGION AND SHOWER
THREAT IS EXPECTED TO DIMINISH. ANOTHER SYSTEM IS FORECAST TO DROP
SOUTH ALONG OR OFF THE WEST COAST LATE IN THE WEEK AND OVER THE
WEEKEND. THERE IS LESS CONFIDENCE ON THE TRACK WITH THIS SYSTEM...
SO WILL EDGE POPS TOWARD CHANCE CATEGORY FOR FRI/SAT FOR NOW.
