...ANOTHER MAJOR PCPN EPISODE FOR N-CENTRAL CALIFORNIA...

...N-CENTRAL CA INTO THE NWRN US...

A MAJOR PCPN EVENT THREAT REMAINS ON TAP. LATEST SATELLITE IMAGERY
AND MODELS STILL STRONGLY INDICATE THAT A STORM SYSTEM WILL TRACK
ENEWD TOWARD THE PAC NW WITH A TRIPLE POINT LOW STILL EXPECTED TO
REACH THE OREGON COAST BY MON MRNG. THIS WILL SPREAD WIDESPREAD
MODERATE TO TERRAIN ENHANCED PCPN/MOUNTAIN SNOWS INLAND AHEAD OF
THIS FEATURE ACROSS THE NWRN US/NRN ROCKIES. UNDERNEATH
THOUGH...YET ANOTHER WELL DEFINED AND LONG FETCH ATMOSPHERIC RIVER
PLUME IS EVIDENT WITH ORIGINS WELL PAST HAWAII INTO THE
SUBTROPICAL W-CENTRAL PACIFIC AS PER BLENDED TPW LOOPS WILL BE
DIRECTED WITH MAIN FOCUS INTO THE CA COAST INVOF SFO BAY REGION
WITH INITIAL WARM FRONTAL BNDRY AS 85H WINDS INCREASE TO 40-50 KTS
WITH PWS OF 1.25-1.4" AND STRONG UPPER JET FOCUS INTO THE AREA
STARTING EARLY MONDAY. AMSU MICOWAVE DATA OFFERS SOME EMBEDDED
.3"/HR RATES THAT COULD LATER DOUBLE INLAND AIDED BY TERRAIN LIFT.
AS THE INITIAL WAVE MOVES INLAND ACRS THE PAC NW MON MRNG...THE
TRAILING COLD FRONT/BAROCLINIC BNDRY IS EXPECTED TO HANG UP INVOF
THE SFO BAY REGION IN RESPONSE TO AN UPSTREAM DVLPG LOW PRES
SYSTEM THAT IS EXPECTED TO DEEPEN OFF THE NRN CA COAST MON AFTN
AND MAIN EFFECTS SLAM INLAND MONDAY NIGHT INTO TUE. THE PROLONGED
AND FOCUSED ATMOSPHERIC RIVER PLUME IS EXPECTED TO LEAD TO VERY
HEAVY RAINS OVER W/SW OR AND ESPECIALLY N-CENTRAL CA. THIS
INCLUDES A FOCUS FROM THE SFO BAY REGION/SANTA CRUZ MOUNTAINS EWD
THROUGH THE SACRAMENTO VALLEY INTO THE SIERRA RANGE WITH DEEP
LAYERED SWLY FLOW PROVIDING VERY FAVORABLE UPSLOPE COMPONENT.
DYNAMIC FORCING AND IMPRESSIVE MSTR PROFILES WILL BE QUITE
FAVORABLE IN SUPPORT FOR SOME OF THE HEAVIER RAINFALL TOTALS
SUGGESTED BY A CONSENSUS OF HI RES GUIDANCE HERE THAT COULD REACH
6-8" LIQUID LOCALLY OVER MOST FAVORED TERRAIN DAY1...WITH STORM
TOTALS UPWARDS TO 8-10" POSSIBLE. MAIN MODEL DIFFERENCES HAVE
REVOLVED AROUND SMALL N/S DIFFERENCES IN WHERE THE MAIN QPF AXIS
WILL SET UP ACRS THE BAY REGION...BUT SPREAD CONTINUES TO DECREASE
APPROACHING THE EVENT. THESE HEAVY RAINS WILL LEAD TO INCREASING
RUNOFF ISSUES ACRS A RATHER BROAD AREA OF CNTL/NRN CA GIVEN THE
RECENT HEAVY RAINS. OPTED TO MAINTAIN CLOSE WPC CONTINUITY AND
ALSO BLENDED IN SOME NDFD FOR CONSISTENCY. FOR DETAILS ON WINTER
WEATHER...SEE THE WPC WINTER WEATHER DESK QPFHSD DISCUSSION.


...SRN PLAINS/MS VALLEY...

STRONG TO SEVERE CONVECION ERUPTED OVER THE SRN PLAINS IN AN
LOADED AIRMASS IN RESPONSE TO EJECTING SW UPR TROF INTERCEPTING
DEEPENING RETURN FLOW FROM FROM THE WRN GULF THROUGH THE SRN
PLAINS. THERE IS ALSO A MID LEVEL MOISTURE CONNECTION ALOFT FROM
THE SUBTROPICAL ERN PACIFIC EVIDENT IN LATEST BLENDED SATELLITE
LOOPS. WAVES INDUCED ALONG THE BANDED CONVECTION ARE FEEDING ON
THE DEEPENED MOISTURE AND INSTABILITY/UPPER DIFFLUENCE AND
ENHANCED JET SUPPORT. SOME OF THE HEAVIER ACTIVITY WILL CONTINUE
TO SHIFT EWD AND NEWD AS PER ADVENT OF STEADY HEIGHT FALLS AND
CONVECTIVE GRADIENTS. MODELS CONTINUE TO SHOW DETAIL DIFFERENCES
WITH THE N/S UPR TROF AXIS EJECTING OUT OF THE ROCKIES INTO THE
PLAINS WITH THESE DIFFERENCES INVOLVING HOW QUICKLY THE TROF
SPLITS AS IT MOVES ACRS THE PLAINS. THE NRN PORTION OF THE TROP
LIFTS NEWD WITH ADDITIONAL INFLUX OF NRN STREAM IMPULSE ENERGY TO
THE UPPER MIDWEST THIS PERIOD. WITH THIS FLOW...HEIGHT FALLS AND
DIFLUENCE SHOULD COMBINE WITH FAVORABLE LEAD THETAE ADVECTION TO
SUPPORT A BAND OF MDT RAIN/SHOWERS ACRS THE REGION BUT EVEN WITH
SOME INCREASED INSTABILITY SHOULD BE LIMITED BY SYSTEM
PROGRESSION. EXPECT MORNING STORMS TOWARD THE UPPER TX COAST WITH
INSTABILITY/MOISTURE...BUT SUSPECT ACTIVITY MAY ALSO DEVELOP
INCREASINGLY OFFSHORE MON AS THE SRN PORTION OF UPR TROF UNDERGOES
TRANSITION TO A CLOSED LOW. HOWEVER...LINGERING SUPPORT AND
MOISTURE SHOULD COMBINE TO SUPPORT A THREAT FOR HEAVY RAINFALL
INVOF ERN TX/OK AND ESPECIALLY SERN TX INTO SRN LA MON THAT MAY
PRODUCE SOME RUNOFF PROBLEMS WITH AMOUNTS UPWARDS OF 2-3"
POSSIBLE/SEVERAL HRS WITH TRAINING IN DEEP FLOW CONSIDERING STILL
ENHANCED PRECIPITABLE WATER VALUES AND LINGERING INSTABILITY.
MAINTAINED REASONABLY CLOSE WPC CONTINUITY. ACTIVITY IS GENERALLY
PROGRESSIVE NOW ON RADAR...BUT OPTED TO SPREAD/REDEVELOP ACTIVITY
EASTWARD ACROSS THE LOWER MS VALLEY SLIGHTLY SLOWER THAN MESO
MODEL CONCENSUS LATER PERIOD GIVEN THE CLOSING NATURE OF THE SRN
PORTION OF THE MAIN TROUGH ALOFT.


DAYS 2 AND 3...


...WESTERN UNITED STATES...

SHORT WAVE ENERGY CROSSING NORTHERN AND CENTRAL CA EARLY ON DAY 2
TAPS DEEPER MOISTURE FOR LOCALLY HEAVY QPF ACROSS THE TERRAIN. A
POSITIVELY TILTED LONG WAVE TROUGH COMES ASHORE ACROSS THE WEST
COAST EARLY ON DAY 3...REACHING A POSITION STRETCHING FROM THE
NORTHERN ROCKIES TO THE SOUTHWEST STATES BY THE END OF PERIOD.
THERE WAS GENERALLY GOOD MODEL AGREEMENT WITH THE OVERALL SYNOPTIC
SETUP...SO THE WPC QPF WAS BASED ON A BLEND OF THE 00Z ECMWF/GFS.

SHORT WAVE ENERGY IN A FAST MID LEVEL FLOW CONTINUES TO AFFECT
NORTHERN AND CENTRAL CA DURING THE FIRST HALF OF DAY 2. A 30 TO 40
KNOT LOW LEVEL WEST SOUTHWEST FLOW TRANSPORT 0.75 INCH
PRECIPITABLE WATER ACROSS THE SIERRA NEVADA RANGE IN CA. THE LOW
LEVEL FLOW IS ORTHOGONAL TO THE TERRAIN OVER THE FAVORED UPSLOPE
AREAS HERE...AND THE THERE IS A MULTI MODEL SIGNAL FOR 1.75 TO
2.25 INCHES OF QPF OVER THE SPAN OF THE SIERRA NEVADA RANGE...WITH
THE HIGHEST AMOUNTS ACROSS THE CENTRAL PORTION OF THE RANGE.
LOWERING SNOW LEVELS WILL HELP TO MITIGATE SOME OF THE FLOOD
THREAT...BUT VERY WET ANTECEDENT CONDITIONS IN THE LOWER
ELEVATIONS COULD POSE ADDITIONAL RUNOFF PROBLEMS. A MARGINAL RISK
WAS PLACED IN THE LOWER ELEVATIONS FOR DAY 2...MAINLY FOR EARLY IN
THE PERIOD...AS THE LOW LEVEL INFLOW DROPS SOUTH AND WEAKENS WITH
TIME.

SOME OF THE MOISTURE IN THE LOW LEVEL FLOW IS TRANSPORTED
NORTHEAST ACROSS PORTIONS OF THE GREAT BASIN AND CENTRAL ROCKIES
DURING THE SECOND HALF OF DAY 2. THE COMBINATION OF MOISTURE IN
THE COLUMN...SYNOPTIC SCALE ASCENT WITH THE SHORT WAVE
ENERGY...AND UPSLOPE FLOW IS EXPECTED TO RESULT IN AN AXIS OF 0.50
TO 1.00 INCHES OF QPF STRETCHING FROM THE GRAND TETONS AND WIND
RIVER MOUNTAINS IN WY SOUTH INTO THE NORTHERN WASATCH AND UNITA
MOUNTAINS IN NORTHERN UT. LESSER QPF AMOUNTS (BETWEEN 0.25 AND
0.50 INCHES) ARE EXPECTED IN THE HIGHER TERRAIN OF NORTHEAST
NV...AS WELL AS THE NORTHERN CO ROCKIES.

FURTHER NORTH...SHORT WAVE ENERGY IN ADVANCE OF A LONG WAVE TROUGH
APPROACHING THE WEST COAST WILL CROSS THE PACIFIC NORTHWEST AND
NORTHERN ROCKIES DURING THE LAST HALF OF DAY 2. WHILE THE LOW
LEVEL FLOW IS FAIRLY STRONG...THE MOISTURE ASSOCIATED WITH THE
SHORT WAVE ENERGY IS NOT QUITE AS ROBUST AS ACROSS CENTRAL CA.
UPSLOPE FLOW WILL MAKE THE MOST OF THE MOISTURE IN THE
COLUMN...RESULTING IN 1.00 TO 1.50 ICH QPF AXES ACROSS THE
SISKIYOU MOUNTAINS IN SOUTHWEST OR...AS WELL AS THE OR CASCADES.
FURTHER EAST...UPSLOPE FLOW AND SYNOPTIC SCALE LIFT FORM SHORT
WAVE ENERGY DROPPING OUT OF WESTERN CANADA IS EXPECTED TO PRODUCE
0.75 TO 1.00 INCH QPF AMOUNTS ACROSS THE SAWTOOTH AND SALMON RIVER
MOUNTAINS IN CENTRAL ID...AS WELL AS THE NORTHERN BITTERROOTS.

A POSITIVELY TILTED LONG WAVE TROUGH COMES ASHORE ACROSS THE WEST
COAST DURING DAY 3...REACHING A POSITION EXTENDING FROM THE
NORTHERN ROCKIES TO THE SOUTHWEST STATES BY THE END OF THE PERIOD.
THE SYNOPTIC SCALE ASCENT ASSOCIATED WITH THE LONG WAVE TROUGH
WILL FOCUS THE REMAINING PACIFIC MOISTURE IN THE FLOW ACROSS THE
HIGHER TERRAIN OF THE PACIFIC NORTHWEST AND NORTHERN AND CENTRAL
CA. AXES OF 0.25 TO 0.50 INCHES OF QPF WERE PLACED ALONG THE
SOUTHERN OR COASTAL RANGE...AS WELL AS THE FAVORED UPSLOPE AREAS
OF THE SIERRA NEVADA RANGE. A CLOSING MID LEVEL SYSTEM ASSOCIATED
WITH THE LONG WAVE TROUGH MOVES OVER THE GREAT BASIN THROUGH THE
CENTRAL ROCKIES...MAINLY DURING THE SECOND HALF OF THE PERIOD. THE
BEST LIFT WITH THE MID LEVEL SYSTEM FOCUSES THE MOISTURE IN THE
COLUMN IN A STRIPE OF 0.50 INCHES OF QPF STRETCHING FROM THE
WASATCH IN UT ACROSS THE UNITA MOUNTAINS IN THE ROCKIES OF
NORTHERN CO AND NEARBY SOUTHEAST WY.

HEAVY SNOWFALL IS EXPECTED ACROSS THE HIGHER TERRAIN OF PORTIONS
OF THE WESTERN UNITED STATES DURING DAYS 2 AND 3. PLEASE REFER TO
THE LATEST SUITE OF WPC WINTER WEATHER PRODUCTS FOR MORE
INFORMATION.


...NORTHERN PLAINS/UPPER GREAT LAKES...

A SERIES OF SHORT WAVES TRACKING FROM WESTERN CANADA ALONG THE
US/CANADIAN BORDER CROSS THE NORTHERN PLAINS...UPPER MS VALLEY AND
UPPER GREAT LAKES DURING DAYS 2 AND 3. THERE WAS GENERALLY GOOD
MODEL AGREEMENT CONCERNING THE OVERALL SYNOPTIC SETUP (THOUGH
THERE WERE SOME TIMING DIFFERENCES WITH THE SHORT WAVES AND THEIR
ATTENDANT SURFACE LOWS). IN AN ATTEMPT TO MITIGATE SOME OF THE
TIMING DIFFERENCES...THE WPC QPF WAS BASED ON A BLEND OF THE 00Z
ECMWF/GFS.

THE FIRST SHORT WAVE IN THE SERIES TRACKS FROM WESTERN CANADA
ACROSS THE US/CANADIAN BORDER NEAR MT/ND DURING DAY 2. MOISTURE IS
THE LIMITING FACTOR WITH THIS FEATURE...AND LOW LEVEL CONVERGENCE
ALONG A FRONTAL BOUNDARY SHOULD RESULT IN AN AXIS OF 0.10 TO 0.25
INCHES OF QPF ON THE BORDER. AS THE SHORT WAVE CROSSES THE UPPER
MS VALLEY AND GREAT LAKES DURING DAY 3...A 30 TO 40 KNOT LOW LEVEL
SOUTHWEST FLOW TRANSPORTS 0.50 INCH PRECIPITABLE WATER AIR OVER
NORTHERN MN/NORTHERN WI AND THE UP OF MI ALONG AND NORTH OF A WARM
FRONT ASSOCIATED WITH A CLIPPER LIKE SURFACE LOW. THE INCREASED
MOISTURE LIFTED AHEAD OF THE SURFACE AND MID LEVEL SYSTEMS IS
EXPECTED TO PRODUCE A STRIPE OF 0.25 TO 0.50 INCHES OF QPF
STRETCHING FROM NORTH CENTRAL MN ACROSS THE UP OF MI...WITH LESSER
AMOUNTS SOUTH ACROSS NORTHERN WI. THERE WAS A MULTI MODEL SIGNAL
FOR THESE QPF AMOUNTS.

THE FINAL IN THE SERIES OF SHORT WAVE DROPPING OUT OF WESTERN
CANADA CROSSES NORTHERN AND EASTERN MT DURING THE LAST PART OF DAY
3. THE BEST LOW LEVEL INFLOW AHEAD OF THE SHORT WAVE FOCUSES THE
RELATIVELY PALTRY AMOUNT OF MOISTURE ALONG THE PATH OF THE SHORT
WAVE...RESULTING IN AN AXIS OF 0.25 TO 0.50 INCHES THE
ABOVEMENTIONED AREAS.


...LOWER MS VALLEY/SOUTHEAST/FL...

A CLOSED MID LEVEL LOW OVER FAR EAST TX EARLY ON DAY 2 TRACKS EAST
SOUTHEAST ACROSS THE GULF OF MEXICO...REACHING A POINT OFF THE
SOUTHWEST FL COAST BY THE END OF THE DAY 3. MODEL SPREAD INCREASES
WITH TIME...WITH SOME NON NCEP SOLUTIONS (SUCH AS THE 00Z
ECMWF/00Z UKMET) FASTER AND WETTER ACROSS THE GULF COAST INTO THE
SOUTHEAST STATES ON DAY 2. BY DAY 3...THE 00Z ECMWF IS AN OUTLIER
WITH ITS SURFACE AND MID LEVEL SYSTEM POSITIONS...AND BECAUSE OF
THIS...ITS SOLUTION WAS NOT EMPLOYED FOR THE WPC QPF ON DAY 3. FOR
THE MOST PART...THE WPC QPF WAS BASED MAINLY ON THE PAST TWO RUNS
OF THE GFS...WHICH HAS SHOWN BETTER CONSISTENCY WITH THIS FEATURE.

A CLOSED MID LEVEL LOW OVER FAR EASTERN TX DROPS SOUTHEAST DURING
DAY 2...REACHING A POSITION SOUTH OF LA BY THE END OF THE PERIOD.
AHEAD OF THE MID LEVEL SYSTEM (AND A WEAKENING FRONT EXTENDING
FROM THE MID MS VALLEY THROUGH THE LOWER MS VALLEY)...A 20 TO 30
KNOT LOW LEVEL SOUTHERLY FLOW TRANSPORTS 1.50/1.75 INCH
PRECIPITABLE WATER AIR (WHICH IS ABOUT TWO STANDARD DEVIATIONS
ABOVE THE MEAN) ACROSS EASTERN LA/SOUTHERN MS/SOUTHERN AL INTO THE
WESTERN FL PANHANDLE. MODEL SOUNDINGS SHOWED MARGINAL INSTABILITY
ROOTED IN THE MOISTURE PLUME...WHICH IS EXPECTED TO FEED
CONVECTION AHEAD OF THE FRONT. AS MENTIONED EARLIER...THERE IS
INCREASING SPREAD OF THE TIMING OF THE MID LEVEL SYSTEM (WITH NON
NCEP SOLUTIONS FASTER IN THE MID LEVELS)...AND THIS HAS
SIGNIFICANT DIFFERENCES IN THE PLACEMENT OF THE CONVECTION...AND
RESULTANT STRIPES OF OF MAXIMA QPF AMOUNTS.

THE FASTER SOLUTIONS DID NOT FACTOR IN THE WPC QPF MUCH FOR DAY 2.
RATHER...THE 00Z GFS PROVIDED THE TEMPLATE FOR QPF FOR DAY 2. THE
TIMING WAS FASTER... EVEN WITH THE 00Z GFS...SO THE MAXIMUM QPF
(GENERALLY BETWEEN 1.00 AND 1.50 INCHES) WAS PLACED OVER SOUTHERN
MS INTO SOUTHWEST AL AND THE FAR WESTERN FL PANHANDLE. BOTH THE
00Z ECMWF AND UKMET HAD MUCH HIGHER QPF AMOUNTS ACROSS THE WESTERN
FL PANHANDLE...SO A MARGINAL RISK WAS EXTENDED INTO THESE AREAS TO
ACCOUNT FOR THE UNCERTAINTY.

THE CLOSED MID LEVEL LOW TRUNDLES TO A POSITION OF THE SOUTHWEST
FL COAST DURING DAY 3...WITH A SURFACE LOW IS ABOUT THE SAME
LOCATION. THE 00Z ECMWF SOLUTION HAD THE SURFACE AND MID LEVEL
SYSTEM FURTHER NORTHEAST...RESULTING IN A FAIRLY LARGE
DISPLACEMENT OF THE HIGHEST QPF AMOUNTS. BECAUSE OF THIS... THE
00Z ECWMF DID NOT FACTOR INTO THE WPC QPF ON DAY 3. FOLLOWING A
00Z GFS LIKE SOLUTION...A LOW LEVEL EAST SOUTHEAST INFLOW
TRANSPORTS 1.50/1.75 INCH PRECIPITABLE WATER ACROSS MUCH OF
CENTRAL AND SOUTHERN FL. LOW LEVEL CONVERGENCE OF THE MOISTURE AND
MARGINAL INSTABILITY SHOULD RESULT IN CONVECTION THAT FAVORS THE
COASTLINE FROM SOUTHWEST FL THROUGH THE MIDDLE OF THE EAST COAST.
IN THESE AREAS...QPF AMOUNTS OF 0.50 TO 1.00 INCHES WERE
PLACED...BUT GIVEN THE AMOUNT OF SPREAD ON DAY 3...THE CONFIDENCE
IN THE PLACEMENT OF THE HEAVIER QPF AMOUNTS IS BELOW AVERAGE.


...OH VALLEY/NORTHEAST...

SHORT WAVE ENERGY TRACKING FROM THE UPPER GREAT LAKES INTO
NORTHERN NEW ENGLAND ON DAY 2 PUSHES A WEAKENING COLD FRONT ACROSS
THE OH VALLEY AND NORTHEAST...AND THE COMBINATION OF MOISTURE AND
ELEVATED INSTABILITY IS EXPECTED TO PRODUCE QPF ACROSS A LARGE
AREA. THERE WAS GENERALLY GOOD MODEL AGREEMENT WITH THE SHORT
WAVE...SO THE WPC QPF WAS BASED ON A BLEND OF THE 00Z ECMWF/GFS.

AHEAD OF THE SHORT WAVE AND WEAKENING SURFACE FRONT...A LOW LEVEL
SOUTHWEST FLOW AIDS IN TRANSPORTING 1.00 INCH PRECIPITABLE WATER
AIR ACROSS THE OH VALLEY AND MUCH OF THE NORTHEAST ON DAY 3. MODEL
SOUNDINGS SHOWED MARGINAL (MAINLY ELEVATED) INSTABILITY STRETCHING
FROM OH ACROSS WESTERN PA INTO EASTERN NY...SO LOW TOPPED
CONVECTION IS POSSIBLE AHEAD OF THE FRONT. A LARGE AREA OF 0.10 TO
0.25 INCHES OF QPF WAS PLACED HERE TO ACCOUNT FOR THE CONVECTIVE
ELEMENTS IN THE GENERAL AREA OF STRATIFORM RAIN.
