AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
915 AM PST TUE JAN 17 2012

.SHORT TERM DISCUSSION...

VERY COLD MORNING BEHIND THE DRY COLD FRONT THAT MOVED THROUGH THE
REGION EARLY YESTERDAY. CLEAR SKIES AND LIGHT WINDS PROVIDED FOR A
GOOD RADIATIONAL COOLING NIGHT ACROSS THE FORECAST AREA. CENTRAL
VALLEY TEMPERATURES REACHED THE LOWER TO MID 20S...WITH THE
NORTHERN SACRAMENTO VALLEY REACHING THE UPPER TEENS. SOME OF THE
COLDER MOUNTAIN BASINS WERE IN THE SINGLE DIGITS. MANY OF THESE
LOWS WERE OF A RECORD-BREAKING NATURE.

TODAY WILL BE THE LAST FAIR-WEATHER DAY IN QUITE SOME TIME FOR
MANY LOCATIONS. LOOK FOR INCREASING HIGH CLOUDS IN THE LATE
MORNING AND AFTERNOON. GIVEN OUR COLD START...TEMPERATURES WILL
LIKELY BE A DEGREE OR TWO COOLER THAN YESTERDAY. LOOK FOR HIGHS IN
THE UPPER 40S TO LOWER 50S ACROSS THE VALLEY WITH 30S AND 40S OVER
THE HIGHER ELEVATIONS.

CLOUD COVER WILL CONTINUE TO INCREASE TONIGHT...WITH MOST AREAS
EXPECTED TO BE CLOUDY EXCEPT POSSIBLY THE NORTHERN SAN JOAQUIN
VALLEY. FOR THIS REASON...OVERNIGHT LOWS SHOULD MODERATE IN MOST
AREAS WITH ABUNDANT CLOUD COVER.

THE FIRST IN A LONG SERIES OF STORMS WILL BEGIN TO IMPACT PARTS OF
THE FORECAST AREA WEDNESDAY. MOST OF THE PRECIPITATION SHOULD
REMAIN NORTH OF INTERSTATE 80 WED...BUT THIS COULD BE AN
INTERESTING STORM WITH THE AMOUNT OF COLD AIR TRAPPED IN THE
NORTHERN MOUNTAINOUS AREAS. LATEST PROGS FROM THE NAM AND LOCAL
WRF SUGGEST THAT SNOW LEVELS COULD GET DOWN TO AROUND 500 FT...LOW
ENOUGH FOR THE REDDING AREA TO GET SNOW. WILL LOOK AT THIS CLOSELY
AND CONSIDER WINTER WEATHER HIGHLIGHTS FOR THE NORTHERN AREAS.

SECOND WEATHER SYSTEM WILL MOVE THROUGH THE AREA THURSDAY. THIS
SYSTEM WILL HAVE BETTER DYNAMICS AND STRONGER WARM AIR ADVECTION
THAN THE WEDNESDAY STORM. FOR THESE REASONS...THE ENTIRE FORECAST
AREA WILL SEE PRECIPITATION WITH THIS STORM. SNOW LEVELS SHOULD BE
ON THE RISE WITH THIS STORM AND SUCCESSIVE STORMS AS WE BEGIN TO
SCOUR OUT THE LOWER LEVEL COLD AIR.

THIRD SYSTEM IS ON TRACK FOR A FRIDAY ARRIVAL. THIS STORM
CURRENTLY LOOKS LIKE THE MOST POTENT AS THE UPPER TROUGH TAKES ON
A NEGATIVE TILT. THIS STORM SHOULD BRING ABOUT A ROUND OF BREEZY
SOUTH WINDS ALONG WITH POSSIBLY MODERATE RAINFALL. DANG

.EXTENDED DISCUSSION (SATURDAY THROUGH TUESDAY)

WET PATTERN WILL CONTINUE WITH ZONAL FLOW BECOMING MORE AMPLIFIED
BRINGING STORMS INTO NORTHERN CALIFORNIA SATURDAY NIGHT INTO MID
NEXT WEEK. THE PW PLUME SHIFTS SOUTH OF THE AREA ON SATURDAY, BUT
GOOD OROGRAPHICS WITH PERPENDICULAR WIND FLOW TO THE MOUNTAINS
WILL KEEP THE THREAT OF PRECIP IN PLACE. THEN ANOTHER SHORT WAVE
MOVES THROUGH SUNDAY. BREEZY TO STRONG WINDS WILL DOMINATE THE
MOUNTAINS DURING EACH WAVE AS THE JET CORE IS NEVER FAR AWAY. THE
SHORT WAVE ON SUNDAY BECOMES A BIT MORE AMPLIFIED AND HAS AN
INJECTION OF COLD AIR BEHIND IT. THE GFS AND ECMWF DIFFER AT THIS
POINT WITH THE GFS BEING MORE PROGRESSIVE THAN THE MORE AMPLIFIED
AND SLOWER ECMWF. THE EC IS DRIER ON MONDAY WITH A TRANSITORY
RIDGE, WHILE THE GFS QUICKLY HAS WARM FRONTAL PRECIP MOVING OVER
THE NORTHERN AREAS SUNDAY NIGHT INTO MONDAY. WITH THE COLD AIR
STILL TRAPPED UNDERNEATH OVER SHASTA COUNTY, THIS WOULD BE THE
SETUP TO GET SOME FREEZING PRECIP OR SNOW INTO REDDING. OF COURSE
THIS IS STILL 6 DAYS OUT AND DETAILS ARE SKETCHY. TUESDAY ANOTHER
ROUND OF MOISTURE IMPACTS THE AREA. JCLAPP

&&

.AVIATION...

PREDOMINANTLY VFR CONDITIONS ARE EXPECTED OVER THE NEXT 24 HOURS.
HIGH CLOUDS WILL PUSH THROUGH THE AREA TODAY IN ADVANCE OF AN
UPPER TROUGH WHICH WILL MOVE INTO NORCAL LATE TONIGHT. THIS
DISTURBANCE WILL BRING A CHANCE OF PRECIP TO THE FAR NORTHERN SAC
VALLEY...IMPACTING MOSTLY KRDD. COLD AIR MAY BE TRAPPED AT THE
SURFACE...LOWERING SNOW LEVELS TO NEAR THE VALLEY FLOOR AT KRDD.
WINDS ARE EXPECTED TO BE GENERALLY LIGHT THROUGH THE PERIOD. -DVC

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