AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE SACRAMENTO CA
330 AM PDT SUN OCT 21 2012

.SHORT TERM DISCUSSION...
A LARGE AND COLD GULF OF ALASKA LOW CONTINUES TO DROP SLOWLY
SOUTHWARD ALONG THE CANADIAN WEST COAST THIS MORNING. AN
APPROXIMATELY 100 TO 120 KNOT POLAR JET WILL CARVE A TROUGH
SOUTHWARD FROM THE LOW OVER THE EASTERN PACIFIC. MAIN FEATURE TO
WATCH OVER THE NEXT 24 HOURS WILL BE A BAROCLINIC LEAF NOW LOCATED
AT ABOUT 38 NORTH...134 WEST. THIS FEATURE WHICH IS BEING PUSHED
ALONG BY ROUGHLY 100 KNOT WINDS IS EXPECTED TO DEVELOP AND PUSH ONTO
THE COAST THIS EVENING AS THE FIRST SIGNIFICANT PACIFIC STORM SYSTEM
OF THE SEASON BRINGING RAIN AND MOUNTAIN SNOW TONIGHT THROUGH
MONDAY. FOR TODAY HOWEVER...INCREASING CLOUDS...COOLER AIRMASS AND
CONTINUED ONSHORE FLOW WILL BRING MUCH COOLER TEMPERATURES WITH
HIGHS TODAY DROPPING TO ABOUT 10 DEGREES BELOW NORMAL.

AS THE MAIN FRONTAL BAND MOVES INTO NORTHWEST CALIFORNIA
TONIGHT...PRECIPITATION WILL SPREAD IN FROM THE WEST WITH AT LEAST
LIGHT PRECIPITATION LIKELY TO REACH THE SIERRA BY THE LATE NIGHT OR
EARLY MORNING HOURS. THE NAM IS JUST A BIT SLOWER WITH THIS SYSTEM
THAN THE GFS BUT BOTH AT LEAST START LIGHT PRECIP OVER THE SIERRA BY
AROUND 06Z. WINTER STORM WARNING FOR THE SIERRA MAY HAVE AN EARLIER
THAN NEEDED START TIME SINCE HEAVIER PRECIP WILL NOT LIKELY HIT THE
SIERRA UNTIL MONDAY MORNING. WILL LEAVE WARNING START TIME ALONE FOR
NOW AND LET LATER SHIFTS ADJUST IF NECESSARY. BREEZY CONDITIONS AND
RAINFALL WILL BE IN STORE FOR THE REST OF THE CWA TONIGHT AS THE
FRONT MOVES INLAND. STILL COOLER TEMPERATURES ARE IN STORE FOR THE
REGION ON MONDAY AS COLD AIR BEHIND THE FRONT FILTERS INLAND. SNOW
LEVELS STILL ON TRACK TO DROP BELOW TRANS SIERRA PASS LEVELS TONIGHT
AND MONDAY WITH SNOWFALL CRITERIA FOR A EARLY SEASON WINTER STORM
WARNING LIKELY TO BE MET. HAVE THEREFORE UPGRADED WINTER STORM WATCH
TO A WARNING. FAIRLY BIG DISCREPANCY ON QPF BETWEEN NAM AND GFS THIS
MORNING. NAM BUFKIT FOR BLUE CANYON IS SHOWING NEARLY 3 FEET OF SNOW
OVER THE SIERRA BETWEEN TONIGHT AND TUESDAY MORNING WHILE GFS ONLY
SHOWING ABOUT 18 INCHES. BELIEVE THIS MAY BE SOMEWHAT OVERDONE FOR
FIRST STORM OF THE SEASON AND STILL TRENDING TOWARDS THE LESSOR
PRECIP AMOUNTS.

FRONTAL SYSTEM FORECAST TO SHIFT SOUTH AND EAST OF THE CWA ON
TUESDAY WITH UPPER TROUGH REMAINING ALONG THE COAST. COLD UNSTABLE
AIR ASSOCIATED WITH THE GULF OF ALASKA LOW WILL CONTINUE TO BRING A
GOOD THREAT OF SHOWERS TO THE FORECAST AREA TUESDAY WITH COLD
AIRMASS CONTINUING TO BRING VERY COOL FOR THE SEASON DAYTIME
TEMPERATURES.  MODELS NOW IN FAIRLY GOOD AGREEMENT IN STARTING TO
SHIFT THE UPPER LOW INLAND BY WEDNESDAY OF NEXT WEEK. SHOWERS WILL
CONTINUE TO BE A THREAT AS THE UPPER TROUGH AXIS SHIFTS EAST OF THE
STATE ESPECIALLY OVER THE NORTHERN CWA. SMITH

&&

.EXTENDED DISCUSSION (THURSDAY THROUGH SUNDAY)

SHOWERS DECREASE AND TEMPERATURES WARM THURSDAY AS UPPER LOW
PROGRESSES INTO THE INTER-MOUNTAIN WEST AND HIGH PRESSURE DEVELOPS
ALONG THE WEST COAST. MODELS SIMILAR IN SLIDING THIS RIDGE OVER THE
AREA FRIDAY INTO SATURDAY FOR DRIER AND WARMER WEATHER MOST AREAS
BUT DIFFER ON AMPLITUDE OF THE RIDGE. A FLATTER RIDGE SCENARIO LIKE
THE GFS WILL ALLOW A THREAT OF OVERRUNNING PRECIP OVER SHASTA COUNTY
NEXT WEEKEND WHILE A MORE AMPLIFIED RIDGE LIKE THE ECMWF AND GEM
PORTRAY WOULD PROBABLY KEEP ANY PRECIP NORTH OF THE FORECAST AREA.
