.PREV DISCUSSION... /ISSUED 316 PM PST TUE NOV 27 2012/
DISCUSSION...THE TURN IN THE PATTERN REMAINS ON TRACK AS THE
FIRST IN A SERIES OF SYSTEMS IS BEARING DOWN ON THE COAST AND
COMING ASHORE LATE TONIGHT. A SOUTHERLY JET THAT IS WRAPPED AROUND
THE UPPER LEVEL LOW BRINGS A FRONT ONTO THE COAST EARLY WEDNESDAY
MORNING. AS THIS SYSTEM MOVES INLAND THE BEST DYNAMICS ARE SOUTH
OF THE REGION AS THE RIGHT ENTRANCE REGION OF THE 110KT JET SWEEPS
THROUGH NORTH CENTRAL CALIFORNIA. HOWEVER...WITH THE BL FLOW FROM
THE SOUTH AT 10-20KT AND 700 MB WINDS ALSO FROM THE SOUTH AT 65KT
THERE WILL BE SIGNIFICANT MOISTURE INFLUX AND OROGRAPHIC LIFT TO
BRING A ROUND OF HEAVY SNOW TO THE HIGHER ELEVATIONS IN THE MT
SHASTA AREA AND THE SISKIYOUS. THERE WILL BE A BRIEF DECREASE IN THE
ACTION WEDNESDAY EVENING INTO THURSDAY MORNING...BUT THEN THE NEXT
SYSTEM MOVES IN WITH A STRONG TROPICAL TAP. WITH SNOW LEVELS
REMAINING MOSTLY STATIC HAVE GONE WITH A WINTER STORM WARNING FOR
THE MOUNT SHASTA REGION ABOVE 4500 FEET AND EXTENDED IT THROUGH THE
SUBSEQUENT SYSTEM WITH WORDING FOR THE BRIEF BREAK. THE THURSDAY
SYSTEM HAS A CONVERGENCE OF FACTORS FOR HEAVY PRECIPITATION
RATES...CONVERGENT BL FLOW...SOUTH TO SW 700MB WINDS AROUND 70KT
PROVIDING STRONG OROGRAPHIC LIFT...STRONG JET DYNAMICS WITH
DIVERGENT FLOW OFF A 110KT JET AND A ATMOSPHERIC RIVER TROPICAL
TAP. AS THE SYNOPTIC PATTERNS ARE NEARLY IDENTICAL BETWEEN THE GFS
AND NAM HAVE LEANED TOWARDS THE NAM12 QPF WITH THE BETTER
GEOGRAPHY IN THE MODEL. THIS VERY WET PATTERN REMAINS WITH SHORT
WAVE AFTER SHORT WAVE SPINNING AROUND THE UPPER LOW OFFSHORE
BRINGING ROUND AFTER ROUND OF PRECIP TO THE REGION...HEAVIEST AT
THE COASTAL RANGES AND NORTHERN CALIFORNIA FROM THE MT SHASTA
REGION WESTWARD. THE UPPER LEVEL LOW OPENS AND THE UPPER LEVEL
TROUGH FINALLY SHIFTS THROUGH THE REGION SUNDAY...SHIFTING THE
TROPICALLY TAPPED JET EAST OF THE REGION WITH COOLER AIR MOVING IN
BEHIND IT BRING SNOW LEVELS DOWN TO THE PASS LEVELS AS THE PRECIP
RATES DROP.
THE MODELS ARE IN FAIRLY GOOD AGREEMENT FRIDAY THROUGH EARLY NEXT
WEEK. A LARGE UPPER LOW REMAINS NEAR THE ALASKA PANHANDLE WITH A
SERIES OF SHORTWAVES ROTATING AROUND THE UPPER LOW AND TAKING AIM
TOWARDS THE OREGON COAST. SO CONFIDENCE IS HIGH WE'LL CONTINUE TO
HAVE A SERIES OF SYSTEMS MOVIE THROUGH THE FORECAST AREA BRINGING
ROUNDS OF MODERATE TO HEAVY PRECIPITATION AND GUSTY WINDS. WHAT'S
NOT AS CLEAR IS THE TIMING OF EACH OF THESE SYSTEMS AND HOW MUCH
OF BREAK WE'LL GET IN BETWEEN THEM. TAKING THINGS AT FACE
VALUE...THE HEAVIEST PRECIPITATION FRIDAY SHOULD SHIFT SOUTH INTO
NORTHERN CAL WITH A RELATIVE BREAK IN THE ACTION FRIDAY AFTERNOON
AND EVENING AS ONE SHORTWAVE MOVES OUT OF THE AREA. ANOTHER
SHORTWAVE ARRIVES FRIDAY NIGHT BRINGING ANOTHER ROUND OF MODERATE
TO HEAVY PRECIPITATION AND GUSTY WINDS. ANOTHER RELATIVE BREAK IS
POSSIBLE SATURDAY...THEN YET ANOTHER ROUND OF MODERATE TO HEAVY
PRECIPITATION AND STRONG WINDS LATE SATURDAY NIGHT THROUGH SUNDAY.
SNOW LEVELS REMAIN HIGH BETWEEN 5500 AND 6500 FEET...THEN LOWERING
TO AROUND 4000 FEET SUNDAY. THE EC AND GFS SUGGEST WE COULD CATCH
AN EXTENDED BREAK SUNDAY NIGHT THROUGH MONDAY BEFORE THE NEXT
FRONT ARRIVES TUESDAY MORNING. STAY TUNED. -PETRUCELLI
