AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
955 PM PST SAT JAN 21 2012

.DISCUSSION...
NORCAL PRESENTLY IN A LULL BEFORE THE NEXT SYSTEM ARRIVES SUNDAY.
SATELLITE IMAGERY SHOWS THE SYSTEM CONTINUING TO DEVELOP WEST OF
130W WITH HIGH CLOUDS OUT AHEAD OF IT ALREADY MOVING INTO THE REGION
THIS EVENING. SIMILAR TO THE FRIDAY/S SYSTEM...THIS ONE WILL ALSO
HAVE A TAP TO DEEP MOISTURE WITH A WIDE SWATH OF INCH PLUS PW NOTED
ON IMAGERY OFF THE NORCAL COAST. STILL APPEARS MAINLY LIGHT
PRECIPITATION WILL HOLD OFF UNTIL AFTER 12Z WHEN WARM ADVECTION
RAPIDLY INCREASES...THEN PRECIPITATION AND WIND INCREASES LATER
SUNDAY AFTERNOON AND EVENING AS COLD FRONT APPROACHES AND
LARGE-SCALE ASCENT INCREASES WITH UPPER JET IMPINGING ON THE REGION.

UPDATES OUT.

&&

.PREVIOUS SHORT TERM DISCUSSION...
SNOW SHOWERS CONTINUE THIS AFTERNOON OVER THE WESTERN SLOPES FOR THE
VALLEY ISOLATED SHOWERS CONTINUE TO POP UP. THIS ACTIVITY WILL ALL
END DURING THE EVENING HOURS.

THE FOCUS NOW IS ON THE NEXT SYSTEM WHICH WILL BE COMING IN ON
SUNDAY. THE HEAVIEST RAINFALL LOOKS TO OCCUR SUNDAY NIGHT INTO
MONDAY MORNING FOR MOST OF THE INTERIOR...BUT SOME MODERATE RAINFALL
COULD START DURING THE MID TO LATE MORNING HOURS FOR THE NORTHERN
COASTAL MOUNTAINS AND FROM AROUND LASSEN PARK NORTHWARD. SNOW LEVELS
WILL NOT BE TOO HIGH BUT WILL BE ABOVE THE FOOTHILLS. ABOVE 6000
FEET 1 TO 2 FEET OF NEW SNOW LOOKS POSSIBLE...WITH LESSOR AMOUNTS
DOWN TO AROUND 4000 FEET FOR THE SOUTHERN AREAS...WHILE OVER THE
NORTH SNOW LEVELS WILL BE AROUND 3000 FT WITH 10 TO 18 INCHES OF
SNOW EXPECTED ABOVE 4500 FEET WITH SEVERAL INCHES OF SNOW DOWN TO
AROUND 3000 FEET.

AS THE JET NOSES OVER THE REGION IN THE AFTERNOON AND EVENING HOURS
WINDS WILL INCREASE ACROSS THE INTERIOR AND BECOME BREEZY TO LOCALLY
WINDY. THE WINDS WILL CONTINUE INTO THE MORNING HOURS OF MONDAY
BEFORE DECREASING AS THE SURFACE LOW PUSHES SOUTHWARD BY MONTEREY
BAY.

BY MONDAY EVENING MOST OF THE INTERIOR WILL BE DRY AND WILL REMAIN
DRY NEXT WEEK. FOG MAY EVENTUALLY BECOME AN ISSUE BY THE MIDDLE OF
NEXT WEEK AS HIGH PRESSURE BUILDS OVER THE REGION. WE HAVE TRIMMED
BACK ON THE PRECIPITATION CHANCES BUT LEFT LOW CHANCES OVER THE
NORTHERN MOUNTAINS ON TUESDAY AND WEDNESDAY DUE TO THE TAIL OF THE
SYSTEMS THAT WILL BE PUSHED INTO THE PACIFIC NORTHWEST JUST BRUSHING
THE FAR NORTHERN AREAS.

&&

.EXTENDED DISCUSSION (WEDNESDAY THROUGH SATURDAY)...
FORECAST CONFIDENCE FOR THE EXTENDED FORECAST IS ABOUT AVERAGE WITH
EASTERN PACIFIC RIDGING RETURNING OVER NORTHERN CALIFORNIA. THIS IS
EXPECTED TO BRING ABOVE NORMAL TEMPERATURES AND GENERALLY DRY
WEATHER TO SOUTHERN PORTIONS OF THE FORECAST AREA. WET GROUND
COUPLED WITH LIGHT WINDS AND LIMITED CLOUD COVER COULD ALLOW SOME
FOG AND MIST TO DEVELOP OVER THE DELTA AND THE VALLEY SOUTH OF
MARYSVILLE ON WEDNESDAY AND THURSDAY MORNINGS. NORTHERLY WINDS
SHOULD INHIBIT FOG FORMATION ON FRIDAY AND SATURDAY.

THE RIDGING MAY FLATTEN ENOUGH TO ALLOW WEAK SHORTWAVES TO PASS OVER
FAR NORTHERN CALIFORNIA. DYNAMICS LOOK RATHER WEAK BUT THERE MAY BE
ENOUGH MOISTURE FOR SOME PRECIPITATION OVER THE NORTHERN MOUNTAINS
EACH DAY. EK
