DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1121 AM CST THU DEC 19 2013

VALID 201200Z - 211200Z

...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...
A PROGRESSIVE/SPLIT LARGE SCALE PATTERN WILL EXIST OVER THE CONUS ON
FRIDAY...HIGHLIGHTED BY EXTENSIVE CYCLONIC UPPER FLOW OVER MUCH OF
THE CONUS AND THE GENERAL EASTWARD ADVANCEMENT OF A POTENT UPPER
TROUGH/POLAR JET OVER NORTHWEST MEXICO. AIR MASS MODIFICATION WILL
STEADILY OCCUR ESPECIALLY OVER THE SOUTH-CENTRAL CONUS...WITH AN
INCREASING MOIST BOUNDARY LAYER BECOMING ESTABLISHED ALONG/SOUTH OF
A FRONTAL ZONE FROM PARTS OF TX/ARKLATEX NORTHEASTWARD INTO THE
LOWER OH RIVER VALLEY.

...PORTIONS OF TX/ARKLATEX...
AS SOUTHERN HIGH PLAINS CYCLOGENESIS GRADUALLY OCCURS FRIDAY...THE
PRIMARY SURFACE BOUNDARY WILL STALL/ORIENT SOUTHWEST-NORTHEASTWARD
FROM SOUTHWEST TX TO THE OH VALLEY...WITH A FRONTAL WAVE/SURFACE LOW
MOVING EASTWARD ACROSS THE MIDWEST/OH VALLEY. WITHIN THE NEARBY WARM
SECTOR...LOWER TO MIDDLE 60S F SURFACE DEWPOINTS WILL BECOME
INCREASING PREVALENT ACROSS THE SOUTHERN HALF OF TX AND ADJACENT
ARKLATEX/LOWER MS RIVER VALLEY.

IN SPITE OF INCREASING BOUNDARY LAYER MOISTURE...THE MAJORITY OF THE
REGION WILL BE INFLUENCED BY WEAK OVERALL FORCING AND SUBTLE HEIGHT
TENDENCIES /IF NOT WEAK HEIGHT RISES/...AT LEAST THROUGH THE
DAYLIGHT HOURS. THIS SCENARIO...WITH AN INCREASINGLY STOUT ELEVATED
MIXED LAYER ACROSS TX...SHOULD GENERALLY CAP THE WARM SECTOR WITH
THE POSSIBLE EXCEPTION OF FRIDAY NIGHT IMMEDIATELY NEAR THE FRONT.

AS GRADUAL HEIGHT FALLS BEGIN TO INFLUENCE TX FRIDAY NIGHT VIA THE
NORTHWEST MEXICO/SOUTHWEST STATES UPPER TROUGH...A STRENGTHENING LOW
LEVEL JET/ASSOCIATED ISENTROPIC UPLIFT FOCUSED NEAR/NORTH OF THE
REGIONAL SURFACE FRONTAL ZONE WILL RESULT IN A NOCTURNAL INCREASE OF
TSTMS. THIS INCLUDES A CORRIDOR FROM SOUTHWEST/CENTRAL TX
NORTHEASTWARD TO THE ARKLATEX/OZARKS. A COUPLE OF NEAR SURFACE-BASED
STORMS CANNOT BE ENTIRELY DISCOUNTED NEAR THE FRONT...BUT THE MOST
PROBABLE/DOMINANT SCENARIO WILL BE FOR STORMS TO DEVELOP/INCREASE ON
THE IMMEDIATE COOL SIDE OF THE SURFACE FRONT...WITH STORMS GENERALLY
ROOTED ABOVE A RELATIVELY COOL/STABLE BOUNDARY LAYER. STRONG SHEAR
THROUGH THE CLOUD LAYER/SUFFICIENT ELEVATED INSTABILITY SUGGEST THAT
MARGINALLY SEVERE HAIL MAY OCCUR WITH A FEW OF THE STORMS. IN SPITE
OF INCREASING DEEP LAYER SHEAR/LENGTHENING LOW-LEVEL
HODOGRAPHS...ANY SEVERE WIND GUST AND/OR BRIEF TORNADO POTENTIAL
WILL BE CONTINGENT UPON NEAR SURFACE-BASED DEVELOPMENT WITHIN THE
WARM SECTOR FRIDAY NIGHT...WHICH APPEARS RELATIVELY LOW/UNCERTAIN AT
THIS TIME.

LATER THIS EVENING...INCREASING LARGE SCALE FORCING FOR ASCENT WILL
SPREAD INTO PORTIONS OF AZ...WHERE ANOTHER ROUND OF SHOWERS AND
THUNDERSTORMS WILL BE POSSIBLE.

DAY1SVR: Day 1 Convective Outlook

ACUS01 KWNS 191258
SWODY1
SPC AC 191256

DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0656 AM CST THU DEC 19 2013

VALID 191300Z - 201200Z

...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...
PATTERN TRANSITION TOWARD WRN CONUS MEAN TROUGH WILL CONTINUE
THROUGH PERIOD. MAIN DRIVER FOR THIS CHANGE IS STG SHORTWAVE TROUGH
-- NOW EVIDENT IN MOISTURE CHANNEL IMAGERY FROM NRN ROCKIES ACROSS
NRN CA TO WATERS OFFSHORE CENTRAL CA COAST. THIS PERTURBATION WILL
CONTINUE TO DIG SSEWD...FORMING CLOSED LOW OVER SRN CA COAST/CHANNEL
ISLANDS AREA BY 00Z. BY 12Z...RESULTING 500-MB CYCLONE SHOULD BE
CENTERED OVER NERN BAJA/NWRN GULF OF CA AREA...S OF YUM...WITH
ASSOCIATED VORTEX COVERING PARTS OF NWRN MEX...SRN CA AND SRN AZ AS
WELL. LARGE DOWNSTREAM FETCH OF SWLY FLOW ALOFT IS EXPECTED TO
DEVELOP BY LATTER PART OF PERIOD...COVERING SRN ROCKIES...SRN
PLAINS...GULF COAST...DIXIE...AND LOWER-MID MS VALLEY. VERY MINOR
PERTURBATIONS MAY BE EMBEDDED WITHIN THAT SWLY FLOW BELT...HOWEVER
PRIMARY AREAS OF DCVA AND HEIGHT FALLS WILL REMAIN JUST AHEAD OF
AZ/NWRN MEX VORTEX.

TIGHTENING SWLY HEIGHT GRADIENT ALOFT WITH SUBSTANTIAL COMPONENT OF
MID-UPPER WINDS ORTHOGONAL TO CENTRAL/SRN ROCKIES IS EXPECTED. THIS
WILL LEAD TO STRENGTHENING OF LOW-LEVEL LEE TROUGHING THROUGH MUCH
OF PERIOD...UNTIL THAT REGIME IS OVERTAKEN FROM N-S BY COLD FRONT.
AT 11Z...SFC ANALYSIS SHOWED THAT FRONT FROM LOWER MI SWWD ACROSS
SRN IA/NRN MO...BECOMING WAVY/QUASISTATIONARY SWD ACROSS
NERN/CENTRAL KS THROUGH DIFFUSE AREA OF LOW PRESSURE OVER SWRN
KS...SERN CO AND OK PANHANDLE. LEE TROUGH EXTENDS FROM THAT AREA
SSWWD ACROSS TX PANHANDLE TO TRANS-PECOS REGION. PLAINS PORTION OF
FRONT SHOULD REMAIN NEAR CURRENT LOCATION THROUGH ABOUT 00Z...THEN
MOVE SWD TO SEWD TOWARD 12Z POSITION NEAR STL-ADM-LBB ARC.

...SWRN CONUS NEAR MID-UPPER LEVEL CYCLONE...
MID-UPPER LEVEL CYCLONE WILL ENGENDER TWO THUNDER-SUPPORTING REGIMES
WITH SOME SPATIAL OVERLAP POSSIBLE ACROSS EXTREME SRN CA.
1. COLD-CORE CONVECTIVE POTENTIAL OVER SRN CA COAST AND ADJACENT
WATERS...AS LARGE-SCALE ASCENT/COOLING ALOFT OCCURS. THIS SHOULD
STEEPEN LOW-MIDDLE LEVEL LAPSE RATES OVER MARINE AIR ENOUGH TO YIELD
100-200 J/KG MUCAPE WITH LITTLE CINH...EXTENDING INTO FAVORABLE
THERMAL LAYERS FOR LTG PRODUCTION...UNDER AND JUST AHEAD OF MIDLEVEL
CYCLONE CENTER.
2. LOW-LEVEL WAA CONVEYOR STRENGTHENS WITH TIME THIS EVENING AND
OVERNIGHT...WHILE SHIFTING EWD FROM SERN CA ACROSS WRN/SRN AZ. SOME
TRAJECTORIES EMANATING FROM SUBTROPICAL PAC WILL BE
POSSIBLE...BOOSTING THETAE IN JUXTAPOSITION WITH ERN RIM OF COOLING
ALOFT. NET RESULT SHOULD BE WEAKLY INHIBITED MUCAPE 100-200
J/KG...WITH SOME ADDITIONAL LIFT POSSIBLE FROM FRONTOGENETIC
FORCING.

...ARKLATEX TO OZARKS/LOWER OH VALLEY...
LOW-LEVEL MOISTURE IS FCST TO INCREASE ACROSS THIS REGION THROUGH
OVERNIGHT HOURS WITHIN IMMATURE/PREFRONTAL RETURN-FLOW
REGIME...AIDED BY 45-55 KT LLJ. PLANAR PROGS AND TIME SERIES OF
FCST SOUNDINGS SHOW MOST CONVECTIVELY AGGRESSIVE MODELS...SUCH AS
NMM MEMBERS OF SREF...BOOSTING LOW-LEVEL THETAE AND REMOVING BASAL
EML CINH ENOUGH TO GENERATE MINIMALLY INHIBITED/ELEVATED CAPE VERY
NEAR END OF PERIOD. HOWEVER...THESE OUTLIER SOLUTIONS STILL OFFER
JUST ISOLATED/BRIEF WINDOW OF LTG RISK AROUND 12Z. AS SUCH...WILL
DEFER OUTLOOK-JUSTIFYING UNCONDITIONAL TSTM PROBABILITIES TO DAY-2
PERIOD.

SPC AC 190953

DAY 4-8 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0353 AM CST THU DEC 19 2013

VALID 221200Z - 271200Z

...DISCUSSION...
...SUN/D4--PORTIONS OF THE SOUTHEAST AND MID-ATLANTIC...
WIDESPREAD SHOWERS/TSTMS /MOST LIKELY IN THE FORM OF A PRE-FRONTAL
CONVECTIVE LINE/ WILL BE ONGOING AT THE START OF THE PERIOD FROM THE
OH/TN VALLEYS SWD TOWARDS THE CNTRL GULF COAST. THE PRIMARY UPPER
TROUGH AND SFC LOW WILL CONTINUE EJECTING NEWD AWAY FROM THIS
AREA...BUT AN ASSOCIATED LOW-LEVEL JET WILL EXTEND DOWN TO THE GULF
COAST AND SHOULD PERSIST ACROSS THE SOUTHEAST INTO THE
AFTERNOON/EVENING. DESPITE MODEST MIDLEVEL LAPSE RATES...RICH
BOUNDARY LAYER MOISTURE WILL YIELD MLCAPE VALUES AROUND 500 J/KG
OVER CNTRL/ERN GULF COAST STATES...DECREASING WITH NWD EXTENT. THIS
SHOULD BE SUFFICIENT TO MAINTAIN SOME SEMBLANCE OF A CONVECTIVE LINE
EWD THROUGHOUT THE DAY...INCLUDING PARTS OF AL/GA AND THE
APPALACHIANS/CAROLINAS. LOW-LEVEL SHEAR WILL LIKELY BE SUFFICIENT
FOR STRONG-SVR WIND GUSTS AND PERHAPS AN ISOLATED TORNADO
THREAT...PRIMARILY OVER AL/GA AND PERHAPS PARTS OF MIDDLE/ERN TN. A
LOWER-END WIND THREAT COULD EXTEND N OF THIS AREA AS WELL.

MID-/UPPER-LEVEL FORCING FOR ASCENT WILL BE QUITE WEAK IN THE WAKE
OF THE LEAD UPPER TROUGH MOVING ACROSS THE GREAT LAKES...AND WELL
DOWNSTREAM FROM A POSITIVE-TILT TROUGH OVER THE GREAT PLAINS. WITH
THE LACK OF FOCUSED SYNOPTIC-SCALE LIFT AND THE LIKELIHOOD OF ONLY A
MARGINALLY UNSTABLE AIR MASS...A 30 PERCENT PROBABILISTIC AREA WILL
NOT BE DELINEATED ATTM.

...MON/D5--IMMEDIATE COASTAL AREAS OF THE SERN ATLANTIC AND
MID-ATLANTIC...
SHOWERS/TSTMS COULD PERSIST ALONG/AHEAD OF THE COLD FRONT THROUGH
LATE MORNING...PRIMARILY ALONG COASTAL AREAS EXTENDING FROM NRN FL
INTO THE CAROLINAS. A NON-ZERO STRONG WIND GUST THREAT MAY EXIST
WITH THIS ACTIVITY WITH MODERATELY STRONG SWLY DEEP-LAYER FLOW
PERSISTING. THE COLD FRONT IS EXPECTED TO MOSTLY BE OFFSHORE BY
AFTERNOON...WITH EXCEPTION TO THE SEGMENT FARTHER S OVER THE FL
PENINSULA.

...TUE/D6 THROUGH THU/D8...
HIGH PRESSURE RETURNS TO MOST OF THE NATION TUE/D6 AND WED/D7.
ANOTHER SHORTWAVE UPPER TROUGH MAY MOVE ACROSS CENTRAL PORTIONS OF
THE CONUS THU/D8...BUT MOISTURE RETURN AHEAD OF THIS SYSTEM IS
LIKELY TO BE LIMITED.
