VALID 130100Z - 131200Z

...NO SVR TSTM AREAS FORECAST...

...SERN U.S...

13/00Z SOUNDING FROM FFC WAS SIGNIFICANTLY MORE MOIST AND UNSTABLE
THAN EARLIER NAM FORECAST SOUNDINGS WITH MUCAPE APPROACHING 200 J/KG
IF LIFTING A 700 MB PARCEL. ISOLATED LIGHTING IS NOTED WITH
CONVECTION ACROSS PORTIONS OF GA AND FOR THIS REASON HAVE EXPANDED
THUNDER PROBABILITIES NWD. FARTHER SOUTH...WEAK SFC CYCLONE HAS
SHIFTED OFF THE NRN FL PENINSULA AND WEAK CONVERGENCE ASSOCIATED
WITH SWD MOVING WIND SHIFT WILL ACCOUNT FOR AT LEAST A LOW
PROBABILITY FOR DEEP CONVECTION CAPABLE OF PRODUCING LIGHTNING.
HOWEVER...SEVERE THREAT APPEARS TOO LOW TO WARRANT ENHANCED PROBS
ACROSS THE PENINSULA THE REMAINDER OF THE PERIOD.

...CA...

13/00Z SOUNDING FROM OAK EXHIBITS WEAK SBCAPE BENEATH UPPER TROUGH
AS IT DIGS SEWD. COOL PROFILES AND WEAK CONVERGENT ONSHORE FLOW MAY
YET PROVE ADEQUATE FOR AN ISOLATED LIGHTNING STRIKE BUT OVERALL
COVERAGE WILL BE QUITE SPARSE THE REST OF THE TONIGHT.

NO CHANGES TO PRIOR OUTLOOK/FORECAST REASONING. SHOWERS HAVE BEEN
GRADUALLY INCREASING SINCE AROUND 1830Z ACROSS MUCH OF THE CENTRAL
FL PENINSULA WITHIN THE WARM SECTOR NEAR/SOUTH OF A FRONTAL

BROKEN MID-HIGH LEVEL CLOUD COVER...WITH MLCAPE ESTIMATED TO BE 500
J/KG OR LESS AS SURFACE DEWPOINTS REMAIN IN THE LOWER 70S THIS
AFTERNOON. WHILE THE DEVELOPMENT/INLAND MOVEMENT OF AT LEAST
ISOLATED TSTMS ARE POSSIBLE YET THIS AFTERNOON/EVENING IN THE
PRESENCE OF MODERATE SHEAR...MODEST CONVERGENCE/MARGINAL

LOCALIZED/MARGINAL IN NATURE.

WIDESPREAD MID/HIGH CLOUDS ARE ACROSS THE FL PENINSULA WHICH WILL
LIMIT DAYTIME HEATING AND DESTABILIZATION. HOWEVER... INCREASING
LARGE SCALE FORCING WILL LIKELY RESULT IN SCATTERED AFTERNOON
SHOWERS AND THUNDERSTORMS. SIMILAR TO THE LAST COUPLE OF
DAYS...DEEP LAYER VERTICAL SHEAR IS SUFFICIENT FOR A RISK OF
ORGANIZED/ROTATING STORMS. THE PRIMARY LIMITING FACTOR FOR SEVERE
STORMS IS THE RATHER WEAK AND VEERED LOW LEVEL WINDS WHICH ARE
LIKELY TO LIMIT CONVERGENCE AND STORM INTENSITY. NEVERTHELESS...
LOCALLY GUSTY WINDS ARE POSSIBLE IN THE STRONGEST CELLS THIS

...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...
LARGE SCALE SPLIT UPPER FLOW WILL PREVAIL OVER NORTH AMERICA ON
THURSDAY. WITHIN THE SOUTHERN STREAM...A LOW AMPLITUDE SHORTWAVE
TROUGH CURRENTLY OVER THE SOUTHEAST STATES WILL QUICKLY EXIT THE
COASTAL SOUTHEAST ON THURSDAY...WHILE A COLD FRONT CONTINUES TO
PROGRESS SOUTHEASTWARD ACROSS SOUTH FL/OFFSHORE WATERS.
MEANWHILE...AN UPPER TROUGH CURRENTLY OFF THE COAST OF CA WILL
CONTINUE TO AMPLIFY/SPREAD EAST-SOUTHEASTWARD TOWARD COASTAL
SOUTHERN CA AND NORTHERN BAJA.

...SOUTH FL...
ALTHOUGH THE COLD FRONT SHOULD CLEAR THE SOUTH FL COAST RELATIVELY
EARLY IN THE DAY...A RELATIVELY NARROW SPATIOTEMPORAL OPPORTUNITY
FOR A FEW TSTMS MAY EXIST FOR SOUTHEAST FL COASTAL AREAS AND
ADJACENT OFFSHORE WATERS.

...SOUTHWEST DESERTS/SOUTHERN ROCKIES...
CONSIDERABLE MOISTENING WILL OCCUR INTO THE REGION ON THURSDAY IN
ADVANCE OF THE EAST-SOUTHEAST ADVANCING UPPER TROUGH IN VICINITY OF
SOUTHERN CA/NORTHERN BAJA. THIS MOISTENING IN CONJUNCTION WITH
RELATIVELY STEEP LAPSE RATES ALOFT/WEAK DESTABILIZATION...AND AMPLE
FORCING FOR ASCENT ACCENTUATED BY AN UPPER JET EXIT REGION...WILL
ACCOUNT FOR AT LEAST ISOLATED TSTM POTENTIAL. THIS WILL MAINLY BE
ACROSS PORTIONS OF THE LOWER CO RIVER VALLEY AND LOWER DESERTS/RIM
VICINITY OF AZ THURSDAY AFTERNOON AND EVENING.

DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0646 AM CST WED DEC 12 2012

VALID 121300Z - 131200Z

...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...
A SRN STREAM SHORTWAVE UPPER TROUGH...CURRENTLY POSITIONED OVER THE
ARKLATEX...IS FORECAST TO DEAMPLIFY WITH ENEWD PROGRESSION ACROSS
THE SOUTHEAST CONUS. A SLOW-MOVING COLD FRONT OVER THE FL PENINSULA
WILL DRIFT SWD...AND WILL AID IN THE DEVELOPMENT OF TSTMS TODAY.
MEANWHILE...A MORE POTENT UPPER TROUGH WILL CONTINUE TO DIG ALONG
THE PACIFIC COAST. MIDLEVEL HEIGHT FALLS/CAA WILL CONTRIBUTE TO
MARGINAL DESTABILIZATION THIS AFTERNOON ACROSS PARTS OF NRN CA...AND
MAY BE SUFFICIENT FOR ISOLATED TSTM DEVELOPMENT.

...CNTRL FL PENINSULA...
A WEAKENING AND SLOW-MOVING COLD FRONT IS POSITIONED NEAR AN OCALA
TO DAYTONA BEACH LINE AS OF 12Z...AND IS FORECAST TO CONTINUE
DRIFTING S TODAY. TSTM DEVELOPMENT IS FORECAST TO PRIMARILY BE
FOCUSED ALONG/AHEAD OF THE COLD FRONT ACROSS THE NRN/CNTRL FL
PENINSULA THROUGH THIS EVENING. A SWLY FETCH OF MOIST GULF AIR /PW
VALUES GENERALLY BETWEEN 1.6-1.8 INCH/ WILL BE MAINTAINED WITHIN THE
PRE-FRONTAL AIR MASS. HOWEVER...INSTABILITY WILL BE SOMEWHAT LIMITED
BY BROKEN CLOUD COVER ACROSS MUCH OF THE PENINSULA...AND MODEST
MIDLEVEL LAPSE RATES OF AROUND 6.5 C/KM. MODIFIED 12Z TBW/MFL
SOUNDINGS INDICATE MLCAPE VALUES WILL INCREASE TO 700-1000 J/KG BY
LATE MORNING.

MIDLEVEL SWLYS OF 30-40 KTS WILL BE SUFFICIENT FOR SOME ORGANIZATION
WITH THE STRONGEST UPDRAFTS. HOWEVER...MIDLEVEL HEIGHT FALLS
ASSOCIATED WITH THE AFOREMENTIONED SHORTWAVE UPPER TROUGH WILL
REMAIN N OF THE COLD FRONT...AND LOW-LEVEL FLOW IS FORECAST TO VEER
AHEAD OF THE COLD FRONT THIS AFTERNOON. THESE FACTORS...ALONG WITH
WEAK INSTABILITY AND MODEST DEEP-LAYER SHEAR...ARE EXPECTED TO ONLY
SUPPORT A MARGINAL THREAT FOR ISOLATED DMGG WIND GUSTS.

...DISCUSSION...
MEDIUM RANGE MODELS CONTINUE TO INDICATE STRONG WEST SOUTHWESTERLY
UPPER JET INTENSIFICATION ACROSS THE CENTRAL AND SOUTHERN TIER OF
THE U.S. BY THIS WEEKEND. THIS FEATURE IS THEN FORECAST TO
GRADUALLY PROPAGATE EAST NORTHEASTWARD INTO THE WESTERN ATLANTIC
...AS ANOTHER STRONG MID-LATITUDE JET NOSES INLAND OFF THE PACIFIC
...AND ACROSS THE U.S. THROUGH THE EARLY TO MIDDLE PART OF NEXT
WEEK. CONFIDENCE IS FAIRLY HIGH THAT VIGOROUS SHORT WAVE IMPULSES
ASSOCIATED WITH THESE FEATURES WILL CONTRIBUTE TO ONE OR MORE
INSTANCES OF STRONG SURFACE CYCLOGENESIS THAT COULD BECOME CAPABLE
OF SUPPORTING A SIGNIFICANT SEVERE WEATHER EVENT. HOWEVER...THE
SPREAD AMONG THE VARIOUS MODELS AND MODEL ENSEMBLE DATA CONCERNING
THE TIMING AND DEVELOPMENT OF THESE FEATURES REMAINS MUCH TOO LARGE
TO CONFIDENTLY ASCERTAIN THE RISK FOR ONE OF THESE EVENTS...AND
GRAPHICALLY DELINEATE A REGIONAL SEVERE WEATHER AREA. IT DOES
SEEM...THOUGH...THAT GUIDANCE IS INCREASINGLY POINTING TOWARD A
ROUGH CORRIDOR ACROSS LOUISIANA/MISSISSIPPI/ ALABAMA AND
GEORGIA...INTO THE CAROLINAS...EITHER LATE THIS WEEKEND OR SOMETIME
DURING THE MIDDLE OF NEXT WEEK.

NWS STORM PREDICTION CENTER NORMAN OK
0229 AM CST WED DEC 12 2012

VALID 141200Z - 151200Z

...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...
MODELS INDICATE THAT STRONG UPPER JET INTENSIFICATION WILL CONTINUE
ACROSS THE CENTRAL AND SOUTHERN TIER OF THE U.S. DURING THIS
FORECAST PERIOD. ACROSS THE PLAINS...THIS FLOW LIKELY WILL TREND
TOWARD WEST SOUTHWESTERLY...AS INITIAL SHORT WAVE RIDGING BREAKS
DOWN IN RESPONSE TO THE NORTHEASTWARD ACCELERATION OF A SIGNIFICANT
SHORT WAVE TROUGH AND EMBEDDED CLOSED LOW OUT OF THE SOUTHWESTERN
STATES. INCREASING SPREAD AMONG THE VARIOUS MODELS CONCERNING THE
DETAILS OF THIS PROCESS BY THURSDAY NIGHT DOES GROW THROUGH
FRIDAY/FRIDAY NIGHT. HOWEVER...IN GENERAL...GUIDANCE INDICATES THAT
A 90+ KT 500 MB SPEED MAXIMUM...NOSING THROUGH THE NORTHWESTERN
MEXICAN PLATEAU AT 12Z FRIDAY...WILL PROPAGATE INTO AND THROUGH THE
SOUTH CENTRAL PLAINS/OZARK PLATEAU REGION BY THE END OF THE PERIOD.
THIS FEATURE MAY WEAKEN IN STRENGTH AS IT DOES...BUT IT APPEARS THAT
STRONG MID-LEVEL HEIGHT FALLS WILL OVERSPREAD THE CENTRAL PLAINS
WITH A SURFACE LOW DEEPENING ACROSS SOUTHEAST COLORADO LATE FRIDAY
AFTERNOON...BEFORE MIGRATING NORTHEASTWARD TOWARD THE MID/LOWER
MISSOURI VALLEY.

FORCING FOR UPWARD VERTICAL MOTION AND COOLING IN THE EXIT REGION OF
THE JET PROBABLY WILL CONTRIBUTE TO A CONTINUING RISK FOR
THUNDERSTORM ACTIVITY ACROSS PARTS OF THE GREAT BASIN AND
CENTRAL/SOUTHERN ROCKIES INTO FRIDAY AFTERNOON. THEREAFTER...THE
PRIMARY CONVECTIVE POTENTIAL WILL SHIFT TO THE PLAINS AND PORTIONS
OF THE MISSOURI/MIDDLE MISSISSIPPI VALLEYS...IN RESPONSE TO THE
LARGE-SCALE FORCING. HOWEVER...AT LEAST THROUGH 12Z SATURDAY...
SIGNIFICANT GULF MOISTURE RETURN MAY NOT OCCUR IN TIME TO SUPPORT
MORE THAN LOW SEVERE WEATHER PROBABILITIES.

...SOUTHERN PLAINS INTO PARTS OF THE OZARK PLATEAU...
GUIDANCE REMAINS SUGGESTIVE THAT THE LACK OF BETTER PHASING BETWEEN
MID/UPPER FORCING FOR UPWARD VERTICAL MOTION AND BOUNDARY LAYER
DESTABILIZATION WILL HINDER THE RISK FOR SEVERE STORM DEVELOPMENT.
MID/UPPER 50S DEW POINTS MAY ONLY ADVECT AS FAR NORTH AS
SOUTHWESTERN OKLAHOMA/NORTHWEST TEXAS PORTIONS OF A DEVELOPING DRY
LINE BY EARLY FRIDAY EVENING...WHEN 60F+ SURFACE DEW POINTS MAY BE
IN THE PROCESS OF DEVELOPING NORTHWARD INTO CENTRAL TEXAS. THIS
APPEARS LIKELY TO BE GENERALLY SOUTH OF THE AXIS OF THE CYCLONIC
MID-LEVEL JET STREAK AS IT NOSES INTO THE SOUTH CENTRAL PLAINS.

HOWEVER...MOISTURE RETURN/DESTABILIZATION AND LIFT ABOVE A RESIDUAL
COOL/STABLE NEAR SURFACE LAYER IS EXPECTED TO SUPPORT ELEVATED STORM
DEVELOPMENT...WHICH COULD BE BECOME CAPABLE OF PRODUCING MARGINALLY
SEVERE HAIL...GENERALLY NORTH OF THE RED RIVER...ACROSS
OKLAHOMA...BEFORE SPREADING INTO ARKANSAS OVERNIGHT.

FARTHER SOUTH...IT MAY NOT BE OUT OF THE QUESTION THAT CONTINUED
NORTHWARD ADVECTION OF BOUNDARY LAYER MOISTURE...AND LIFT ASSOCIATED
WITH LOW-LEVEL WARM ADVECTION...COULD SUPPORT BOUNDARY LAYER BASED
OR NEAR BOUNDARY LAYER BASED STORM DEVELOPMENT ACROSS PARTS OF
NORTHERN TEXAS OVERNIGHT. IF THIS OCCURS...VERTICAL SHEAR WILL BE
MORE THAN SUFFICIENT FOR SUPERCELLS.

NWS STORM PREDICTION CENTER NORMAN OK
1200 AM CST WED DEC 12 2012

VALID 131200Z - 141200Z

...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...
THE SPREAD AMONG THE VARIOUS MODEL ENSEMBLE DATA REMAINS LARGE FOR
THIS FORECAST PERIOD CONCERNING SHORT WAVE DEVELOPMENTS WITHIN A
STRONG MID-LATITUDE JET PROPAGATING EASTWARD ACROSS THE PACIFIC.
THIS INCLUDES ONE IMPULSE FORECAST TO EMERGE FROM THE JET AND
PROGRESS THROUGH AMPLIFIED UPPER RIDGING ACROSS THE NORTHEAST
PACIFIC...BEFORE DIGGING TOWARD THE BRITISH COLUMBIA AND PACIFIC
NORTHWEST COAST. IN THE PROCESS...THIS FEATURE APPEARS LIKELY TO
SPLIT...WITH ONE PORTION MIGRATING EASTWARD IN A ZONAL BRANCH OF
FLOW EXTENDING EASTWARD INTO CANADA...WHILE ANOTHER PORTION
CONTINUES TO DIG IN A BRANCH TO THE SOUTH...CURVING INTO A
SIGNIFICANT UPPER TROUGH ACROSS THE CALIFORNIA COAST.

VARIABILITY EXISTS AMONG THE MODELS CONCERNING THE
MAGNITUDE/EVOLUTION OF THE PERTURBATIONS EVOLVING OUT OF THE
SPLIT...AND THIS BEGINS TO INCREASE THE SPREAD CONCERNING THE
EASTWARD ACCELERATION AND EVOLUTION OF THE CALIFORNIA TROUGH AND
EMBEDDED CLOSED LOW. THIS LATTER SYSTEM DOES STILL APPEAR LIKELY TO
PROGRESS INTO THE GREAT BASIN AND SOUTHERN U.S./NORTHWESTERN MEXICAN
PLATEAU...WHILE INTERACTING WITH ANOTHER BELT OF WESTERLIES EMERGING
FROM THE SUBTROPICAL EASTERN PACIFIC. AS IT DOES...STRONG UPPER JET
INTENSIFICATION IS FORECAST ACROSS THE NORTHERN MEXICAN PLATEAU INTO
THE CREST OF AMPLIFYING SHORT WAVE RIDGING ACROSS THE SOUTHERN
PLAINS.

IN RESPONSE TO UPPER DEVELOPMENTS AND ASSOCIATED SURFACE PRESSURE
FALLS ACROSS THE CENTRAL/SOUTHERN HIGH PLAINS...A RETURN FLOW OF
LOW-LEVEL MOISTURE MAY COMMENCE OFF THE WESTERN GULF OF MEXICO...
WHILE A PLUME OF HIGH LEVEL MOISTURE ADVECTS EAST NORTHEASTWARD
ALONG THE SOUTHEASTERN FRINGE OF THE UPPER JET. SUBSTANTIVE
BOUNDARY LAYER MOISTENING IS NOT EXPECTED INTO DEEP SOUTH TEXAS
UNTIL LATE IN THE PERIOD...BUT MAY OCCUR ABOVE A RESIDUAL COOL
STABLE SURFACE-BASED LAYER AS FAR NORTH AS PARTS OF CENTRAL AND
NORTHERN TEXAS. HOWEVER...LOWER/MID TROPOSPHERIC WARMING ABOVE THIS
LAYER PROBABLY WILL CAP POTENTIAL DESTABILIZATION. AS A
RESULT...CONVECTIVE POTENTIAL ACROSS THE SOUTHERN PLAINS IS EXPECTED
TO REMAIN NEGLIGIBLE THURSDAY AND THURSDAY NIGHT. WITH THE POSSIBLE
EXCEPTION OF A LINGERING RISK FOR THUNDERSTORMS NEAR SOUTHEAST
FLORIDA COASTAL AREAS...THIS WILL ALSO BE THE CASE ELSEWHERE EAST OF
THE PLAINS.

...GREAT BASIN/SOUTHERN PLATEAU/ROCKIES...
SIGNIFICANT MOISTENING IS FORECAST ACROSS THE REGION ON SOUTHERLY
LOW-LEVEL FLOW AHEAD OF THE UPPER TROUGH. IN CONJUNCTION WITH
BOUNDARY LAYER WARMING AND MID-LEVEL COOLING WITH THE APPROACH OF
THE TROUGH...AT LEAST WEAK DESTABILIZATION IS EXPECTED. COUPLED
WITH LARGE-SCALE FORCING FOR UPWARD VERTICAL MOTION...THIS SHOULD BE
SUFFICIENT FOR THE DEVELOPMENT OF SCATTERED THUNDERSTORMS LATE
THURSDAY INTO THURSDAY NIGHT. HIGHEST PROBABILITIES APPEAR TO EXIST
ALONG AND SOUTH OF THE MOGOLLON RIM...ACROSS THE LOWER DESERTS
AROUND PHOENIX. HOWEVER...THE RISK FOR THUNDERSTORMS MAY NOT BE
NEGLIGIBLE ACROSS PARTS OF EASTERN NEVADA INTO WESTERN UTAH...AND
NORTHEAST OF THE RIM...INTO THE FOUR CORNERS REGION AND THE
SOUTHWESTERN TWO-THIRDS OR SO OF NEW MEXICO LATE THURSDAY NIGHT.

DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1117 PM CST TUE DEC 11 2012

VALID 121200Z - 131200Z

...NO SVR TSTM AREAS FORECAST...

...SYNOPSIS...
A SHORTWAVE OVER THE ARKLATEX EARLY THIS MORNING WILL QUICKLY TRACK
EWD ACROSS THE CNTRL GULF COAST STATES DURING THE AFTERNOON AND THE
CAROLINAS BY THURSDAY MORNING. MEANWHILE...A COLD FRONT OVER THE NRN
FL PENINSULA WILL SLOWLY SAG SOUTHWARD ACROSS THE STATE DURING THE
AFTERNOON AND OVERNIGHT HOURS...PROVIDING SOME FOCUS FOR
THUNDERSTORM DEVELOPMENT. OTHERWISE...A PROGRESSIVE PATTERN WILL
PERSIST TODAY AS A DEEPENING SHORTWAVE IMPULSE OFF THE CA/ORE COAST
ROTATES E/SE TOWARD CNTRL CA AND THE GREAT BASIN. WEAK CYCLOGENESIS
TO THE NORTH AND EAST OF THE SAN FRANCISCO BAY AREA IN NRN CA MAY
AID IN ISOLATED THUNDERSTORM DEVELOPMENT THROUGH EARLY EVENING...AS
A COLD FRONT DROPS SWD FROM THE PACIFIC NW/NRN ROCKIES INTO THE
GREAT BASIN BY 12Z THURSDAY.

...CNTRL FL PENINSULA...
A WARM...MOIST AIRMASS AHEAD OF AFOREMENTIONED COLD FRONT IS
EXPECTED WITH TEMPERATURES IN THE MID 70S TO LOW 80S AND DEWPOINTS
IN THE UPPER 60S TO MID 70S. DESPITE THIS...UNCERTAINTY IN THE
DEGREE OF DESTABILIZATION DURING PEAK HEATING EXISTS DUE TO EXPECTED
CLOUD COVER. MODEST DEEP LAYER SHEAR AND FORCING FOR ASCENT ALONG
THE COLD FRONT FROM GLANCING SHORTWAVE MAY SUPPORT LOOSELY ORGANIZED
CONVECTION AND MARGINAL SEVERE THREAT IN STRONGEST CELLS.
HOWEVER...POOR MID LEVEL LAPSE RATES...LIGHT LOW LEVEL WINDS AND
ONLY WEAKLY VEERING PROFILES WILL LIMIT WIDESPREAD ORGANIZED SEVERE
THREAT.
