CONCERNING...TORNADO WATCH 82...

VALID 041823Z - 042000Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 82 CONTINUES.

SUMMARY...THREAT FOR DAMAGING WIND...HAIL AND ISOLATED TORNADOES
WILL PERSIST INTO EARLY EVENING AS STORMS CONTINUE TO DEVELOP
THROUGH S FL.

DISCUSSION...LINE OF CONVECTION ASSOCIATED WITH A PROGRESSIVE MCS
EXTENDS FROM S CNTRL FL SWWD INTO THE ERN GULF. THE BOUNDARY LAYER
OVER SOUTH FL CONTINUES TO DESTABILIZE WITH TEMPERATURES WARMING
INTO THE LOW 80S...BUT OVERALL MAGNITUDE OF INSTABILITY WILL REMAIN
SOMEWHAT LIMITED BY WEAK MID LEVEL LAPSE RATES WITH MLCAPE AROUND
1500-2000 J/KG. VWP DATA INDICATE 35-45 KT EFFECTIVE SHEAR WHICH
WILL SUPPORT THE POTENTIAL FOR A FEW ORGANIZED STORM STRUCTURES.
HOWEVER...WINDS IN 0-2 KM LAYER ARE WEAK RESULTING IN RELATIVELY
SMALL HODOGRAPHS AND SUGGESTING TORNADO POTENTIAL WILL BE SUPPORTED
MAINLY BY MESOSCALE PROCESSES SUCH AS UPDRAFT-BOUNDARY INTERACTIONS.
STORMS WITHIN THE LINE WILL CONTINUE EWD THROUGH WARM SECTOR NEXT
FEW HOURS WITH POTENTIAL FOR EMBEDDED MESO-VORTICES AND BOWING
STRUCTURES. OTHER MORE DISCRETE ACTIVITY DEVELOPING IN WARM SECTOR
MAY EVENTUALLY DEVELOP UPDRAFT ROTATION AND POSE A SEVERE RISK.

DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1226 PM CDT THU APR 04 2013

VALID 051200Z - 061200Z

...THERE IS A SLGT RISK OF SVR TSTMS ACROSS SOUTH FL...

...SYNOPSIS...
A PROGRESSIVE/INCREASINGLY LOW AMPLITUDE LARGE SCALE PATTERN WILL
PREVAIL OVER THE CONUS ON FRIDAY IN THE WAKE OF SPLIT/CYCLONIC UPPER
FLOW OVER THE EASTERN CONUS. PRIMARY TSTM/SEVERE POTENTIAL WILL
EXIST THROUGH THE MORNING/AFTERNOON ACROSS SOUTH FL IN GENERAL
ASSOCIATION WITH AN EAST-SOUTHEAST MOVING SOUTHERN STREAM
TROUGH/COLD FRONT. OTHER TSTMS WILL BE POSSIBLE OVER THE
NORTHERN/CENTRAL ROCKIES DURING THE DAY...AND INTO PORTIONS OF THE
MIDDLE/UPPER MO RIVER VALLEY FRIDAY NIGHT/EARLY SATURDAY IN
ASSOCIATION WITH A STRENGTHENING WARM ADVECTION REGIME.

...SOUTH FL/FL KEYS...
SCATTERED TO POTENTIALLY NUMEROUS TSTMS ARE LIKELY TO BE
ONGOING/MOVING INLAND FRIDAY MORNING NEAR AND IMMEDIATELY AHEAD OF
THE SOUTHEASTWARD-MOVING COLD FRONT...AND/OR PERHAPS RESIDUAL
OUTFLOW. THE SPECIFIC DEGREE OF DESTABILIZATION IS A BIT OF
UNCERTAIN GIVEN THE POTENTIAL EARLY DAY NATURE OF THE THREAT AND
UNKNOWN DETAILS REGARDING CLOUD COVER/ONGOING PRECIPITATION.
HOWEVER...A MOIST INFLUX OF UPPER 60S/LOWER 70S F SURFACE DEWPOINTS
AND SOME COOLING ALOFT /ATTENDANT TO THE APPROACHING UPPER TROUGH/
MAY CONTRIBUTE TO AS MUCH AS 1000 J/KG SBCAPE.

WHILE LOW LEVEL WINDS WILL LIKELY VEER DURING THE DAY...FORCING FOR
ASCENT/UPLIFT ASSOCIATED WITH THE APPROACHING UPPER TROUGH/COLD
FRONT AND THE PRESENCE OF A RELATIVELY STRONG/NEARLY UNIDIRECTIONAL
WIND PROFILE WILL SUPPORT THE SUSTENANCE OF A SQUALL LINE/LINE
SEGMENTS...AND PERHAPS A FEW EMBEDDED SUPERCELLS/VORTICES. ISOLATED
BOUTS OF DAMAGING WINDS/PERHAPS A TORNADO WILL BE POSSIBLE PRIOR TO
THE COLD FRONT CLEARING THE COAST DURING THE AFTERNOON...AND/OR
CONVECTIVE OVERTURNING PRIOR TO THAT.

...WY TO NORTH-CENTRAL HIGH PLAINS...
AN EASTWARD-MOVING LOW AMPLITUDE SHORTWAVE TROUGH WILL LIKELY AID
TSTM DEVELOPMENT ACROSS THE REGION FRIDAY AFTERNOON/EARLY EVENING.
WHILE OVERALL MOISTURE/DESTABILIZATION WILL BE QUITE LIMITED...A
WELL-MIXED BOUNDARY AND RELATIVELY STRONG WEST-SOUTHWESTERLY
MID-LEVEL WINDS /40+ KT/ COULD SUPPORT SOME STRONGER WIND
GUSTS/DOWNDRAFTS IN ASSOCIATION WITH CONVECTION. THE OVERALL
SCENARIO APPEARS MARGINAL AT THIS TIME...BUT THE REGION WILL BE
REEVALUATED DURING THE DAY 1 PERIOD FOR THE POSSIBLE INCLUSION OF
LOW TSTM WIND PROBABILITIES.

1056 AM CDT THU APR 04 2013

VALID 041630Z - 051200Z

...THERE IS A SLGT RISK OF SVR TSTMS FOR MUCH OF FL AND FAR SE GA...

...SYNOPSIS...
ERN OK/TX UPR TROUGH SHOULD CONTINUE ESE INTO LA THIS EVE BEFORE
REACHING THE FL PANHANDLE/N CNTRL GULF EARLY FRI. AHEAD OF THE
TROUGH...SATELLITE AND MODEL DATA SUGGEST PRESENCE OF A WEAKER
DISTURBANCE NOW ENTERING THE ERN GULF OF MEXICO THAT SHOULD FURTHER
DEAMPLIFY AS IT CONTINUES ENE ACROSS THE FL PENINSULA LATER
TODAY/EARLY TNGT.

AT LWR LVLS...WEAK SFC LOW NOW NEAR PENSACOLA EXPECTED TO REFORM
ENEWD TO JUST OFF THE GA CST BY EVE...BEFORE DEEPENING AND
CONTINUING NEWD ALONG SC/NC CST EARLY FRI. THIS SHOULD ALLOW S GA
WEDGE FRONT TO SAG A LITTLE SWD INTO PARTS OF THE FL PANHANDLE LATER
TODAY. WHILE A SECONDARY SFC WAVE MAY FORM ALONG THIS BOUNDARY TNGT
OVER THE FAR NERN GULF AS THE MAIN UPR TROUGH APPROACHES FROM THE
LWR MS VLY...CONVERGENCE WITH THE FEATURE SHOULD REMAIN LIMITED
GIVEN EXPECTED DEEPENING OF LOW ALONG THE CAROLINA CST.

FARTHER S...WEAK W-E OUTFLOW BOUNDARY FROM OVERNIGHT SHOWERS/STORMS
IN CNTRL FL EXPECTED TO HOLD NEARLY STNRY TODAY...REINFORCED BY
DIFFERENTIAL HEATING/RAIN WITH MCS NOW ENTERING THE WRN PART OF THE
PENINSULA. THIS BOUNDARY...AND POSSIBLY THE E CST SEA BREEZE FRONT
TO ITS S...SHOULD SERVE AS THE MAIN FOCUS FOR STRONG TO POTENTIALLY
SVR TSTMS THIS PERIOD.

...FL/FAR SE GA TODAY THROUGH TNGT...
SATELLITE AND SFC DATA OVER THE GULF OF MEXICO/NW FL INDICATE THAT
THE MAIN SYNOPTIC COLD FRONT ASSOCIATED WITH THE OK/TX UPR TROUGH
ATTM EXTENDS FROM SSW FROM THE PENSACOLA SFC WAVE INTO THE CNTRL
GULF. THIS FRONT SHOULD CONTINUE STEADILY ESE THROUGH THE
PERIOD...AND MAY SERVE AS A FOCUS OF STORM DEVELOPMENT OVER THE NERN
GULF LATE IN THE PERIOD. HOWEVER...GIVEN PRESENCE OF THE MOST RECENT
IN A SERIES OF LARGE MCSS THAT HAS MOVED OFF THE FRONT AND
OVERTURNED AIR MASS OVER MUCH OF THE CNTRL/ERN GULF...EXPECT THAT
THE MAIN AREA FOR STRONG TO POTENTIALLY SVR WEATHER THIS PERIOD WILL
BE CONFINED TO THE ERN SIDE OF THE MCS AS IT MOVES/DEVELOPS
GENERALLY ESE ACROSS THE SRN HALF OF THE OF PENINSULA LATER
TODAY/TNGT...WITH OTHER STORMS LIKELY FORMING AHEAD OF IT.

ALTHOUGH WIND FIELDS WILL NOT BE PARTICULARLY STRONG...THEY WILL BE
AMPLE FOR SUSTAINED STORMS/SUPERCELLS ACROSS MUCH OF FL...ESPECIALLY
LATER TODAY THROUGH EARLY FRI AS UPR TROUGH APPROACHES THE REGION
AND 700 MB WSW WINDS INCREASE TO AOA 40 KTS. COUPLED WITH 25-30 KT
SLY NEAR-SFC FLOW...SETUP COULD FOSTER LOW-LVL MESO
FORMATION/TORNADO DEVELOPMENT IN ANY SUSTAINED STORMS...ESPECIALLY
ALONG AND S OF OUTFLOW BOUNDARY GIVEN MOISTURE-RICH LOW-LVL
ENVIRONMENT /PW AOA 1.50 INCHES/ AND WEAK CIN/MODERATE SFC HEATING
EXPECTED THERE. OTHER STORMS MAY FORM S OF THE BOUNDARY IN
STRENGTHENING/CONFLUENT LOW-LVL FLOW.

WHILE THE OVERALL SVR THREAT DOES NOT APPEAR TO BE AS GREAT OVER NRN
AND N CNTRL FL AS THAT FARTHER S...WILL MAINTAIN LWR CONDITIONAL SVR
PROBABILITIES IN THAT REGION FOR BOTH /1/ POSSIBLE DIURNALLY-DRIVEN
DEVELOPMENT TODAY IN AREA OF WEAK CONVERGENCE ALONG AND S OF WEDGE
FRONT...AND /2/ FOR POTENTIAL ISOLD STORM DEVELOPMENT IMMEDIATELY
AHEAD OF UPR TROUGH LATE TNGT/EARLY FRI MOVING INLAND FROM THE NERN

VALID 041408Z - 041515Z

PROBABILITY OF WATCH ISSUANCE...80 PERCENT

SUMMARY...THREAT FOR DAMAGING WIND AND ISOLATED TORNADOES IS
EXPECTED TO INCREASE THIS MORNING AND INTO THE AFTERNOON AS STORMS
MOVE INLAND NEAR AND SOUTH OF THE TAMPA BAY AREA. OTHER STORMS MAY
DEVELOP OVER S FL. A WW WILL LIKELY BE NEEDED SOON.

DISCUSSION...THIS MORNING A STATIONARY E-W ORIENTED OUTFLOW BOUNDARY
WITH ACTIVE CONVECTION EXTENDS FROM NEAR TAMPA THROUGH CNTRL FL. A
MOIST WARM SECTOR EXISTS SOUTH OF THIS BOUNDARY WITH DEWPOINTS
GENERALLY IN THE UPPER 60S...AND VISIBLE SATELLITE IMAGERY SHOWS
NUMEROUS BREAKS SUGGESTING THE BOUNDARY LAYER WILL CONTINUE TO
DESTABILIZE AS DIABATIC WARMING COMMENCES. THE MIAMI SOUNDING
INDICATED A SOMEWHAT SHALLOW BOUNDARY LAYER...AND DEWPOINTS COULD
MIX DOWN SLIGHTLY AS HEATING COMMENCES...BUT AT LEAST MID 60S SHOULD
BE REPRESENTATIVE WITH MLCAPE AROUND 1500-2000 J/KG AS TEMPERATURES
WARM INTO THE 80S. VWP DATA INDICATE DEEP SHEAR FROM 30-35 KT OVER
CNTRL FL. THOUGH 0-1 KM HODOGRAPHS ARE NOT PARTICULARLY
LARGE...VEERING LOW LEVEL PROFILES EXIST...AND STORMS MAY ALSO
INTERACT WITH E-W ORIENTED BOUNDARY ACROSS CNTRL FL...POSSIBLY
AUGMENTING THREAT FOR ISOLATED TORNADOES. LINE OF STORMS JUST OFF
THE WEST COAST OF FL ALREADY SHOWS ORGANIZED STRUCTURES WITH
EMBEDDED SUPERCELLS. OTHER STORMS MAY DEVELOP ACROSS S FL IN
ASSOCIATION WITH SEA-BREEZE CIRCULATIONS WHERE THE ATMOSPHERE IS
MORE UNSTABLE AND DEEP SHEAR AROUND 45-50 KT IS SUPPORTIVE OF
SUPERCELLS.

DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0716 AM CDT THU APR 04 2013

VALID 041300Z - 051200Z

...THERE IS A SLGT RISK OF SVR TSTMS TODAY AND TONIGHT ACROSS THE
FLORIDA PENINSULA...AND PARTS OF NORTHERN FLORIDA INTO SOUTHERN
GEORGIA...

...SYNOPSIS...
THE MID-LATITUDE WESTERLIES REMAIN SPLIT ACROSS THE EASTERN PACIFIC
INTO WESTERN NORTH AMERICA...BUT FLOW WILL CONTINUE TO TREND TO A
MORE ZONAL REGIME...AS A SIGNIFICANT SHORT WAVE IMPULSE FLATTENS
SOUTHERN STREAM RIDGING ACROSS THE INTERMOUNTAIN WEST AND ROCKIES.
DOWNSTREAM...A PAIR OF SIGNIFICANT SHORT WAVE IMPULSES WILL CONTINUE
TO DIG EAST SOUTHEASTWARD. ONE...IN THE NORTHERN STREAM...TO THE
SOUTH OF HUDSON BAY...LIKELY WILL BE ACCOMPANIED BY ANOTHER
INTRUSION OF COLD AIR INTO THE GREAT LAKES REGION AND NEW ENGLAND.
THE OTHER...IN THE SOUTHERN STREAM...MAY CONTRIBUTE TO SURFACE
CYCLOGENESIS ALONG THE SOUTH ATLANTIC COAST DURING THE LATTER HALF
OF THE PERIOD...AS IT ACCELERATES A BIT ACROSS THE LOWER MISSISSIPPI
VALLEY/WESTERN GULF COAST REGION...INTO THE EASTERN GULF COAST AND
GULF OF MEXICO BY 12Z FRIDAY.

A WEAK AREA OF LOW PRESSURE ALREADY HAS FORMED OVER THE NORTHEAST
GULF OF MEXICO. THIS IS ALONG THE BAROCLINIC ZONE ASSOCIATED WITH
THE SHALLOW SOUTHERN EDGE OF THE RECENT COLD INTRUSION WHICH REACHED
GULF COASTAL AREAS...WHILE THE DEEPER FRONTAL SURGE STALLED ACROSS
PARTS OF THE TENNESSEE VALLEY AND NORTHERN GULF STATES INTO THE
SOUTH ATLANTIC SEABOARD. THE LOW MAY TRACK INLAND ACROSS NORTHERN
FLORIDA AND SOUTHERN GEORGIA TODAY...BUT LITTLE SUBSTANTIVE
DEEPENING APPEARS LIKELY UNTIL IT REACHES CAROLINA COASTAL AREAS
LATER TONIGHT. AS A RESULT...GUIDANCE GENERALLY SUGGESTS ONLY A
WEAK TO MODEST /30 KT OR SO/ SOUTHWESTERLY 850 MB FLOW DEVELOPING
INLAND ACROSS THE CENTRAL PENINSULA AND NORTHEAST FLORIDA THROUGH
THE DAYTIME HOURS. STILL...THIS SHOULD BE SUFFICIENT TO ENHANCE THE
RISK FOR SEVERE STORMS...IN THE PRESENCE OF AT LEAST MODERATELY
STRONG DEEP LAYER SHEAR...AND A MOISTENING BOUNDARY LAYER.

...FLORIDA AND ADJACENT SOUTHERN GEORGIA...
SPC STORM-SCALE ENSEMBLE MEMBERS DO NOT APPEAR TO HAVE A GOOD HANDLE
ON CURRENT CONVECTIVE DEVELOPMENTS OVER THE GULF OF MEXICO. IT IS
NOT CLEAR THAT THE LAST FEW RUNS OF THE HIGH RESOLUTION RAPID
REFRESH DO EITHER. BUT CONSIDERABLE OTHER MODEL DATA...AS WELL AS
OBSERVATIONAL DATA...DO APPEAR TO PROVIDE SUPPORT FOR THE GENERAL
IDEA OF INCREASING SEVERE WEATHER POTENTIAL BY EARLY AFTERNOON
ACROSS THE CENTRAL FLORIDA PENINSULA. THIS IS EXPECTED TO OCCUR IN
ASSOCIATION WITH THE EASTWARD PROGRESSION OF A PERTURBATION
ASSOCIATED WITH THE ONGOING CLUSTER OF STORMS OVER THE EASTERN GULF
OF MEXICO.

DIFLUENT AND DIVERGENT HIGH LEVEL FLOW...BETWEEN THE SOUTHERN STREAM
JET NOSING ACROSS THE NORTHERN GULF OF MEXICO...AND THE SUBTROPICAL
JET EXTENDING EAST NORTHEASTWARD ACROSS THE SOUTHERN GULF OF MEXICO
THROUGH THE BAHAMAS...MAY PROVIDE CONTINUING SUPPORT FOR THE
CONVECTIVE CLUSTER...WHICH MAY PROGRESS INLAND NEAR/SOUTH OF TAMPA
BY 17-20Z. AROUND THE SAME TIME...OR SHORTLY THEREAFTER...IT ALSO
APPEARS THAT BOUNDARY LAYER WARMING AND DESTABILIZATION...IN THE
WAKE OF WEAK CONVECTION CURRENTLY OVERSPREADING THE CENTRAL
PENINSULA...WILL BECOME SUFFICIENT TO SUPPORT INCREASING DISCRETE
STORM DEVELOPMENT ALONG THE SEA BREEZE ACROSS THE EAST CENTRAL
PENINSULA.

ALTHOUGH NOT PARTICULARLY STRONG...LOW-LEVEL HODOGRAPHS APPEAR
SUFFICIENT...COUPLED WITH THE RELATIVELY HIGH BOUNDARY LAYER
MOISTURE CONTENT AND HUMIDITY...TO SUPPORT THE RISK FOR A FEW
TORNADOES WITH THE DISCRETE STORMS...IN ADDITION TO THE POTENTIAL
FOR LARGE HAIL. OTHERWISE...DAMAGING WIND POTENTIAL WILL BE HIGHEST
WITH THE STORM CLUSTER PROGRESSING INLAND OFF THE GULF OF
MEXICO...AND ANY POSSIBLE UPSCALE CONVECTIVE GROWTH OVER THE EASTERN
PENINSULA LATER THIS AFTERNOON AND EVENING.

TO THE NORTH...ANY STORM DEVELOPMENT CLOSER TO THE SURFACE LOW
ACROSS NORTHERN FLORIDA AND SOUTHERN GEORGIA IS EXPECTED TO BE MORE
ISOLATED IN NATURE. INSTABILITY IS ALSO EXPECTED TO REMAIN
CONSIDERABLY WEAKER. BUT FORCING/SHEAR IN THE EXIT REGION OF THE
APPROACHING SOUTHERN STREAM JET MAY PROVIDE SUPPORT FOR SUPERCELLS.

DAY 4-8 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0340 AM CDT THU APR 04 2013

VALID 071200Z - 121200Z

...DISCUSSION...
...SUNDAY/D4 - NERN OK INTO THE LOWER MO VALLEY...
MODELS ARE IN GOOD AGREEMENT IN MOVING A LOW AMPLITUDE SHORTWAVE
TROUGH FROM THE ROCKIES EWD ACROSS THE CNTRL PLAINS DURING THE DAY
AND TO THE MS RIVER BY 12Z MON. THIS PATTERN WILL ALLOW LOW LEVEL
MOISTURE TO INCREASE ON SLY FLOW AROUND THE WRN ATLANTIC
ANTICYCLONE...WITH MID TO UPPER 50S F DEWPOINTS INTO KS AND MO BY
00Z. ISENTROPIC LIFT N OF THE WARM FRONT WILL BE ENHANCED BY THE
SHORTWAVE TROUGH...AND SCATTERED THUNDERSTORMS ARE EXPECTED TO LIFT
NEWD ACROSS ERN KS...MO...IA...AND IL DURING THE EVENING AND
OVERNIGHT. COOL TEMPERATURE PROFILES ALOFT AND ADEQUATE CLOUD
BEARING SHEAR MAY SUPPORT SOME MARGINALLY SEVERE HAIL.

...MONDAY/D5 - CNTRL AND WRN KS...NWRN OK...
MODELS INDICATE THE WRN TROUGH AMPLIFYING ON MON WITH A 90 KT
MIDLEVEL SPEED MAX DIGGING SEWD ACROSS CA AND NOSING INTO THE SRN
HIGH PLAINS BY TUE MORNING WITH STRONG HEIGHT FALLS. AT THE
SURFACE...LOW PRESSURE IS FORECAST TO DEEPEN SOMEWHERE NEAR THE
TX/OK PANHANDLE AREA...WITH A WARM FRONT EXTENDING EWD ACROSS KS AND
INTO MO. A DRYLINE SHOULD EXTEND SWD NEAR THE TX/WRN OK BORDER AS
WELL. LOWER 60S F BOUNDARY LAYER DEWPOINTS SHOULD EXIST ACROSS MUCH
OF THE WARM SECTOR...WITH MID 60S F TO THE RED RIVER. WITH COOL
TEMPERATURES ALOFT...THIS WILL RESULT IN MODERATE INSTABILITY
LEVELS.

THE MOST LIKELY AREA FOR CONCENTRATED SEVERE STORMS APPEARS TO BE
OVER SWRN KS...WHERE COOLER AIR ALOFT WILL RESULT IN THE LEAST
AMOUNT OF CAPPING POTENTIAL AND WHERE SFC CONVERGENCE WILL BE
MAXIMIZED ALONG WITH HEATING. WIND PROFILES WILL BE DECIDEDLY
SUPERCELLULAR WITH EXTREME HAIL POSSIBLE AS WELL AS A FEW TORNADOES.
DURING THE EVENING...WARM ADVECTION WITH THE NOCTURNAL LOW LEVEL JET
WILL BE MAXIMIZED AND MAY INCREASE STORM COVERAGE. THE MAIN MODEL
DIFFERENCE IS HOW THE EVENING STORMS MAY BE FORCED. THE GFS
INDICATES A COLD FRONT SURGING SWD. IF THIS OCCURS...INITIAL
SUPERCELLS COULD EVENTUALLY MERGE INTO AN MCS. THE ECMWF SOLUTION IS
MORE SUPPORTIVE OF CONTINUED SUPERCELLS AFTER DARK WITH THE BOUNDARY
REMAINING STATIONARY ACROSS NRN KS.

MORE ISOLATED STORMS ARE LIKELY SWD INTO WRN OK/TX ALONG THE
DRYLINE...BUT THIS THREAT AREA COULD BE CONFINED TO A NARROW ZONE AS
CAPPING INCREASES TO THE E. RECENT HEAVY RAINS AND DECREASED SURFACE
ALBEDO MAY PROVIDE A FEEDBACK MECHANISM FOR COOLER TEMPERATURES AS
WELL.

...TUESDAY/D6 TO THURSDAY/D8 - ERN OK/ARKLATEX INTO THE MIDDLE AND
LOWER MS VALLEY...
AFOREMENTIONED COLD FRONT DEPICTED BY GFS IS FORECAST TO SURGE SWD
AND WILL BECOME A PRIMARY FOCUS FOR CONVECTION FROM NRN IL INTO MO
AND OK...LINKING WITH THE DRYLINE OVER N CNTRL TX. BY
TUESDAY...SUBSTANTIAL BOUNDARY LAYER MOISTURE WILL BE IN PLACE WITH
UPPER 60S F DEWPOINTS AHEAD OF THE FRONT.

MEANWHILE...THE ECMWF SOLUTION KEEPS THE SYNOPTIC FRONT STATIONARY
ACROSS SRN NEB INTO NRN IL/IND DURING THE DAY ON TUE...WITH THE
DRYLINE FROM CNTRL KS INTO OK AND CNTRL TX. THIS MODEL ALSO
INDICATES SUBSTANTIAL MOISTURE AND INSTABILITY POTENTIAL FROM
KS/OK/TX INTO THE LOWER MS VALLEY.

GIVEN THESE MODEL DIFFERENCES...PREDICTABILITY IS TOO LOW FOR AN
AREA ON TUE/D6...ALTHOUGH THERE IS THE POTENTIAL FOR SIGNIFICANT
SEVERE INCLUDING TORNADOES. THE THREAT SHOULD PERSIST INTO WED/D7
ACROSS THE LOWER MS VALLEY. AREAS ARE LIKELY TO BE INTRODUCED AS
PREDICTABILITY INCREASES IN SUBSEQUENT OUTLOOKS.

GUSTS AND HAIL NEAR SVR LIMITS ARE POSSIBLE. MRGL NATURE AND
LIMITED SPATIAL EXTENT OF THREAT INDICATE WW IS NOT LIKELY TO BE
REQUIRED.

DISCUSSION...SFC MESOANALYSIS SHOWS QUASISTATIONARY/SYNOPTIC FRONT
ACROSS NRN FL EXTENDING INTO FRONTAL-WAVE LOW JUST SW AAF. WELL S
OF THAT...DIFFUSE OUTFLOW BOUNDARY WAS DRAWN FROM NEAR MLB WWD
ACROSS NRN PORTIONS TAMPA BAY AREA THEN NWWD ACROSS GULF INTO LOW.
SFC TROUGH AND CORRESPONDING WIND-SHIFT LINE EXTENDED FROM NEAR TPA
SSWWD ACROSS GULF TO ABOUT 100 W FMY AND BEYOND. BAND OF TSTMS HAS
DEVELOPED ALONG THAT TROUGH AND NEAR SFC MOIST/WARM AXES THAT EXTEND
NWD FROM YUCATAN STRAIT. COASTAL AIR MASS ALONG AND S OF OUTFLOW
BOUNDARY IS CHARACTERIZED BY SFC DEW POINTS UPPER 60S F AND TEMPS
LOW 70S...NOT QUITE AS WARM ON EITHER COUNT AS OVER CONVECTIVE
GENESIS AREA OFFSHORE BUT STILL POTENTIALLY SUPPORTING SFC-BASED
EFFECTIVE INFLOW PARCELS. SFC THETAE DIMINISHES WITH EWD EXTENT
FROM CURRENT CONVECTIVE AREA TO COAST AND IS MINIMIZED INLAND NEAR
COAST. THIS FACTOR AND WEAK LAPSE RATES ALOFT COMBINE TO YIELD
RELATIVE MIN IN MUCAPE NEAR COAST -- LESS THAN 500 J/KG BASED ON
MODIFIED FCST SOUNDINGS.

THIS PRECONVECTIVE ENVIRONMENT SHOULD CONTINUE THROUGH REMAINDER
OVERNIGHT HOURS...WITH SOME FURTHER LOSS OF INLAND THETAE DUE TO
ADDITIONAL DIABATIC SFC COOLING. SOME ONSHORE FLOW IS POSSIBLE
LATER TODAY -- I.E. AFTER ABOUT 15Z -- HOWEVER UNTIL
THEN...COAST-PARALLEL TO SLGT OFFSHORE COMPONENT SHOULD MAINTAIN
TIGHT THETAE/INSTABILITY GRADIENT INVOF COAST. AS SUCH...CONVECTIVE
POTENTIAL WITH INLAND EXTENT BECOMES MORE CONDITIONAL AND SVR THREAT
VERY LOW...DESPITE FAVORABLE KINEMATIC ENVIRONMENT WITH 40-50 KT

...SYNOPSIS...
A SHORTWAVE TROUGH WILL CONTINUE EWD ACROSS THE SERN

AIR ALOFT AND MOISTENING MAY LEAD TO ISOLATED WEAK THUNDERSTORMS
DURING THE DAY FROM ERN ID AND UT INTO MT/WY/CO.

...SRN FL INCLUDING THE KEYS...
NUMEROUS THUNDERSTORMS ARE EXPECTED TO BE ONGOING ALONG THE COLD

VALID 041200Z - 051200Z

...THERE IS A SLGT RISK OF SVR TSTMS ACROSS FL...

...FL...

SUBSTANTIAL MID-HIGH LEVEL FLOW WILL SPREAD ACROSS THE GULF BASIN
TOWARD THE NRN FL PENINSULA DURING THE DAY WHICH SHOULD ENCOURAGE
WEAK SFC CYCLOGENESIS OVER THE FL PANHANDLE WITH SUBSEQUENT MOVEMENT
EXPECTED EWD ALONG THE GA/FL BORDER DURING THE EVENING. DEEPER SFC
DEVELOPMENT IS EXPECTED DURING THE OVERNIGHT HOURS NEAR THE CAROLINA
COAST BUT BUOYANCY WILL BE VERY LIMITED INLAND.

IT/S NOT ENTIRELY CLEAR WHAT PARTICULAR CONVECTIVE SCENARIO WILL
PROVE MOST SIGNIFICANT OTHER THAN DIURNALLY ENHANCED CONVECTION WILL
LIKELY BE NOTED ACROSS THE PENINSULA DUE TO MODEST HEATING.
SIGNIFICANT THUNDERSTORM ACTIVITY IS CURRENTLY ONGOING ACROSS THE
CNTRL GULF BASIN WHERE AT LEAST TWO MCS-TYPE CLUSTERS ARE NOTED.
THIS ACTIVITY SHOULD NOT SPREAD INLAND BEFORE SUNRISE ALTHOUGH
INCREASING LOW LEVEL WARM ADVECTION IS EXPECTED TO GENERATE TSTMS
AHEAD OF AFOREMENTIONED SFC CYCLONE OVER THE FL PANHANDLE EARLY.
FORECAST SOUNDINGS SUGGEST LOW LEVEL SHEAR IS NOT EXPECTED TO BE
PARTICULARLY STRONG IN ASSOCIATION WITH THIS SFC LOW BUT SIGNIFICANT
DEEP LAYER SHEAR AND WEAK WARM ADVECTION FAVOR DEEP ROTATING
UPDRAFTS CAPABLE OF EXHIBITING SUPERCELL CHARACTERISTICS. BY MID
DAY SIGNIFICANT BOUNDARY LAYER HEATING SHOULD ENHANCE THE PROSPECT
FOR MORE DISCRETE SUPERCELLS ACROSS CNTRL FL...POSSIBLY AIDED BY
LOCAL SEA BREEZES. A GRADUAL SWD SHIFT IN DEEP CONVECTION IS
EXPECTED THROUGH THE PERIOD WITH POSSIBLY AN ENHANCED THREAT ALONG
THE ADVANCING COLD FRONT DURING THE OVERNIGHT HOURS. A MULTIFACETED
TSTM SCENARIO WILL LIKELY BE NOTED FRIDAY DUE TO THE WARM
ADVECTION...DIURNAL HEATING...AND FRONTAL FORCING EXPECTED.

LATEST FORECAST SOUNDINGS SUGGEST CONVECTION THAT DEVELOPS DURING
THE AFTERNOON HOURS WILL BE ROOTED IN SBCAPE ON THE ORDER OF 1700
J/KG WITH POTENTIALLY STEEP SFC-2KM LAPSE RATES. THIS ACTIVITY
COULD PRODUCE HAIL THE SIZE OF GOLF BALLS AND LOCALLY DAMAGING WINDS
GIVEN THE EXPECTED INSTABILITY. ISOLATED TORNADOES MAY ALSO BE
NOTED WITH ANY SUPERCELLS GIVEN THE MOISTURE/SHEAR PROFILES.

AT THIS TIME WILL NOT INTRODUCE HIGHER SEVERE PROBS DUE TO THE LACK
OF CLARITY IN HOW/WHERE CONVECTION WILL ULTIMATELY EVOLVE.


...PACIFIC NW...

FORCING WILL INCREASE ACROSS ORE INTO NRN CA DURING THE AFTERNOON
HOURS AHEAD OF PROGRESSIVE SHORT-WAVE TROUGH. WEAK INSTABILITY IS
EXPECTED TO SUPPORT ISOLATED THUNDERSTORMS AIDED IN LARGE PART BY
DIURNAL HEATING.
