MEAN LARGE-SCALE TROUGH WILL PERSIST FROM HUDSON BAY REGION SWD
ACROSS UPPER GREAT LAKES AND MS VALLEY. SERIES OF MOSTLY
LOW-AMPLITUDE/SUBTLE SHORTWAVES ARE EXPECTED TO TRAVERSE ASSOCIATED
CYCLONIC-FLOW FIELD OVER UPPER MIDWEST AND GREAT LAKES...WITH ONE

TO MOVE SWD ACROSS CENTRAL CANADA DURING NEXT COUPLE DAYS...BECOMING
ENTRAINED IN WRN/SWRN PORTION OF PREVAILING CYCLONIC PATTERN AS IT
CROSSES SERN MB/NRN MN THIS PERIOD. THIS TROUGH SHOULD REACH WRN

...NRN APPALACHIANS/OH VALLEY TO SRN PLAINS...
ISOLATED TO WIDELY SCATTERED TSTMS MAY DEVELOP INVOF SFC FRONTAL
ZONE IN ANY OF THREE REGIMES...EACH OF WHICH WILL BE STRONGLY
LIMITED IN SVR RISK BY LACK OF SHEAR AND/OR BUOYANCY --
1. CARRYOVER FROM DAY-1 OVERNIGHT PERIOD...WITH ELEVATED TSTMS
EMBEDDED IN WEAKENING REGIME OF LOW-LEVEL WAA AND MOISTURE
TRANSPORT. THIS IS MOST PROBABLE INVOF OZARKS/LOWER OH VALLEY
REGION...MOVING ENEWD TO NEWD AND WEAKENING DURING MIDDAY.
2 AND 3. DIURNAL DEVELOPMENT INVOF FRONT--WITH ENERGY SPLIT BETWEEN
NRN APPALACHIAN/LOWER GREAT LAKES AND OZARKS REGIMES DEPENDING ON
STABILIZING EFFECTS OF CLOUDS/PRECIP FROM MORNING ACTIVITY IN
BETWEEN. NERN AREA WILL BE CHARACTERIZED BY STG DEEP-LAYER
SHEAR...BUT WEAKNESS OF BOTH INSTABILITY AND LOW-LEVEL LIFT NEAR
FRONTAL ZONE. OZARKS/AR/OK REGIME WILL HAVE DEEPLY MIXED SUBCLOUD
LAYERS...BUT ALSO...WEAK VERTICAL SHEAR AND LIMITED CAPE DUE TO LACK
OF MOISTURE. THIS BOUNDARY SHOULD ACCELERATE SEWD ACROSS SRN PLAINS
DURING PERIOD...THEN SWD OVER OZARKS AND NRN MID-SOUTH REGION LATE
IN PERIOD AS FRONTAL WAVE MOVES ENEWD ACROSS REGION.

...UPPER GREAT LAKES REGION...
ISOLATED TO WIDELY SCATTERED...LOW-TOPPED TSTMS ARE POSSIBLE
PRIMARILY DURING AFTERNOON/EARLY EVENING HOURS. A FEW CELLS MAY
PRODUCE STG GUSTS OR HAIL NEAR SVR LIMITS...HOWEVER BUOYANCY APPEARS
TOO WEAK TO SUPPORT ORGANIZED SVR POTENTIAL. FCST SOUNDINGS SUGGEST
PATCHES OF DIURNAL HEATING...WITH TEMPS REACHING 60S F...WILL BE
SUFFICIENT TO REMOVE CINH. SPECIFIC BOUNDARIES FOR DEVELOPMENT
APPEAR NEBULOUS...THOUGH WEAKLY BAROCLINIC SFC TROUGH SHOULD CROSS

A LARGE UPPER TROUGH IS ENTRENCHED OVER THE UPPER MIDWEST TODAY WITH
SEVERAL SHORTWAVE TROUGHS DIGGING SOUTHEASTWARD ACROSS THE NORTHERN
PLAINS. ONE OF THESE FEATURES IS NOTED ON WATER VAPOR IMAGERY OVER
WESTERN SD MOVING INTO NE. MODELS SHOW THIS IMPULSE TRACKING
QUICKLY SOUTHEASTWARD ACROSS THE NORTHERN PLAINS INTO PARTS OF KS/MO
LATE AFTERNOON THROUGH LATE EVENING. A WEAK SURFACE BOUNDARY THAT
CURRENTLY EXTENDS ACROSS MO/KS WILL STALL THIS AFTERNOON AND PROVIDE
LOW LEVEL FOCUS FOR SCATTERED THUNDERSTORM DEVELOPMENT. LOW LEVEL
MOISTURE SOUTH OF THE BOUNDARY WILL BE MEAGER WITH DEWPOINTS ONLY IN
THE 50S, WITH LOW LEVELS 850/925 FAIRLY DRY. HOWEVER...COOLING
TEMPERATURES ALOFT AND STRENGTHENING LOW LEVEL WARM ADVECTION WILL
PROVIDE INCREASINGLY FAVORABLE LIFT AND INSTABILITY FOR CONVECTIVE
DEVELOPMENT ACROSS SOUTHERN MO INTO EASTERN OK THIS EVENING. THOSE
STORMS THAT FORM WILL POSE A RISK OF HAIL AS THEY TRACK TOWARD
SOUTHERN IL. ORGANIZED SEVERE ACTIVITY IS NOT CURRENTLY
ANTICIPATED.

ELSEWHERE...ISOLATED THUNDERSTORMS WILL CONTINUE TO HOLD ON ALONG
THE FRONTAL BOUNDARY AS IT EXTENDS NORTHEASTWARD FROM CENTRAL MO /

0730 AM CDT THU SEP 20 2012

VALID 201300Z - 211200Z

...NO SVR TSTM AREAS FORECAST...

...CENTRAL PLAINS INTO MIDDLE MS VALLEY...
A LARGE UPPER TROUGH WILL BECOME ENTRENCHED OVER THE UPPER MIDWEST
TODAY WITH SEVERAL SHORTWAVE TROUGHS DIGGING SOUTHEASTWARD ACROSS
THE NORTHERN PLAINS. ONE OF THESE FEATURES IS NOTED ON WATER VAPOR
IMAGERY OVER EASTERN MT/WESTERN ND. MODELS SHOW THIS IMPULSE
TRACKING QUICKLY ACROSS THE NORTHERN PLAINS AND INTO PARTS OF
NEB/IA/KS/MO AFTER DARK. A WEAK SURFACE BOUNDARY THAT CURRENTLY
EXTENDS ACROSS MO/KS WILL STALL THIS AFTERNOON AND PROVIDE LOW LEVEL
FOCUS FOR SCATTERED THUNDERSTORM DEVELOPMENT. LOW LEVEL MOISTURE
SOUTH OF THE BOUNDARY WILL BE MEAGER WITH DEWPOINTS ONLY IN THE 50S.
HOWEVER...COOLING TEMPERATURES ALOFT AND STRENGTHENING LOW LEVEL
WARM ADVECTION WILL PROVIDE INCREASINGLY FAVORABLE LIFT AND
INSTABILITY FOR CONVECTIVE DEVELOPMENT ACROSS SOUTHERN MO INTO
EASTERN OK THIS EVENING. THOSE STORMS THAT FORM WILL POSE A RISK OF
HAIL AS THEY TRACK TOWARD SOUTHERN IL. ORGANIZED SEVERE ACTIVITY IS
NOT CURRENTLY ANTICIPATED.

ELSEWHERE...SCATTERED THUNDERSTORMS WILL CONTINUE FOR A FEW MORE
HOURS ALONG AN AXIS FROM IL INTO OH/LOWER MI. ALSO...SCATTERED
SHOWERS AND THUNDERSTORMS ARE EXPECTED THIS AFTERNOON AND EVENING
OVER MUCH OF FL AND SOUTHERN GA. SEVERE WEATHER IS NOT EXPECTED IN
THESE AREAS.

SHOULD REACH ERN IA...NRN IL AND SRN WI REGION BY 22/12Z.

AT SFC...FRONTAL ZONE NOW ANALYZED ACROSS ERN LS...LM...NRN MO AND
SRN KS...WILL MOVE SLOWLY EWD ACROSS GREAT LAKES REGION AND WILL BE
REINFORCED ACROSS SRN PLAINS THROUGH DAY-2.

...NRN APPALACHIANS/OH VALLEY TO SRN PLAINS...
ISOLATED TO WIDELY SCATTERED TSTMS MAY DEVELOP INVOF SFC FRONTAL
ZONE IN ANY OF THREE REGIMES...EACH OF WHICH WILL BE STRONGLY
LIMITED IN SVR RISK BY LACK OF SHEAR AND/OR BUOYANCY --
1. CARRYOVER FROM DAY-1 OVERNIGHT PERIOD...WITH ELEVATED TSTMS
EMBEDDED IN WEAKENING REGIME OF LOW-LEVEL WAA AND MOISTURE
TRANSPORT. THIS IS MOST PROBABLE INVOF OZARKS/LOWER OH VALLEY
REGION...MOVING ENEWD TO NEWD AND WEAKENING DURING MIDDAY.
2 AND 3. DIURNAL DEVELOPMENT INVOF FRONT--WHICH MAY BE BIFURCATED
FURTHER INTO NRN APPALACHIAN/LOWER GREAT LAKES AND OZARKS REGIMES
DEPENDING ON STABILIZING EFFECTS OF CLOUDS/PRECIP FROM MORNING
ACTIVITY IN BETWEEN. NERN AREA WILL BE CHARACTERIZED BY STG
DEEP-LAYER SHEAR...BUT WEAKNESS OF BOTH INSTABILITY AND LOW-LEVEL
LIFT NEAR FRONTAL ZONE. OZARKS/AR/OK REGIME WILL HAVE DEEPLY MIXED
SUBCLOUD LAYERS...BUT ALSO...WEAK VERTICAL SHEAR AND LIMITED CAPE
DUE TO LACK OF MOISTURE. THIS BOUNDARY SHOULD ACCELERATE SEWD
ACROSS SRN PLAINS DURING PERIOD...THEN SWD OVER OZARKS AND NRN
MID-SOUTH REGION LATE IN PERIOD AS FRONTAL WAVE MOVES ENEWD ACROSS
REGION.

...UPPER GREAT LAKES REGION...
ISOLATED TO WIDELY SCATTERED...LOW-TOPPED TSTMS ARE POSSIBLE
PRIMARILY DURING AFTERNOON/EARLY EVENING HOURS. A FEW CELLS MAY
PRODUCE STG GUSTS OR HAIL NEAR SVR LIMITS...HOWEVER BUOYANCY APPEARS
TOO WEAK TO SUPPORT ORGANIZED SVR POTENTIAL. FCST SOUNDINGS SUGGEST
PATCHES OF DIURNAL HEATING...WITH TEMPS REACHING 60S F...WILL
SUFFICIENT TO REMOVE CINH. SPECIFIC BOUNDARIES/FOCI FOR DEVELOPMENT
APPEAR NEBULOUS...THOUGH WEAKLY BAROCLINIC SFC TROUGH SHOULD CROSS
WI/LM/LOWER MI DURING DAY. MLCAPE SHOULD REMAIN BELOW 500
J/KG...WITH SOME REACHING INTO THERMAL LAYER SUITABLE FOR LTG
PRODUCTION.

...SERN CONUS...
RESIDUAL FRONTAL ZONE...NOW ALIGNED SW-NE ACROSS CENTRAL GULF AND
NRN FL...SHOULD REMAIN OVER SAME GENERAL AREA THROUGH DAY-2...WITH
ONLY MESOSCALE PERTURBATIONS/MOVEMENTS. RICH LOW-LEVEL MOISTURE
NEAR FRONT...AND ALONG SEA BREEZE BOUNDARIES TO ITS S...WILL
CONTRIBUTE TO TSTM POTENTIAL. HOWEVER...WITH SVR THREAT VERY
LIMITED BY WEAKNESS OF BOTH SHEAR AND LAPSE RATES.

DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1233 AM CDT THU SEP 20 2012

VALID 201200Z - 211200Z

...NO SVR TSTM AREAS FORECAST...

...SERN KS/SWRN MO...

WEAK SFC FRONT IS EXPECTED TO STALL ACROSS NRN OK EARLY IN THE
PERIOD BEFORE RETREATING TOWARD THE KS BORDER BY 21/00Z. IN THE
ABSENCE OF MEANINGFUL LARGE SCALE FORCING THIS FEATURE SHOULD MOVE
LITTLE THROUGH THE OVERNIGHT HOURS. LATEST MODEL GUIDANCE SUGGEST
STRONG BOUNDARY LAYER HEATING WILL OCCUR ACROSS THE WARM SECTOR FROM
NWRN TX INTO CNTRL OK WHERE SFC TEMPERATURES SHOULD WARM INTO THE
MID 90S. THESE READINGS WILL BE CLOSE TO CONVECTIVE TEMPERATURES
AND ISOLATED HIGH BASED THUNDERSTORMS COULD EVOLVE DURING THE LATE
AFTERNOON/EARLY EVENING FROM THE ERN TX PANHANDLE TOWARD NCNTRL OK.
HOWEVER THIS ACTIVITY SHOULD PROVE RATHER SPARSE AND SHOULD WEAKEN
WITH LOSS OF DAYTIME HEATING. LATEST NAM GUIDANCE IS FAIRLY
AGGRESSIVE REGARDING THE STRENGTHENING OF LLJ...ALBEIT SIGNIFICANTLY
VEERED...ACROSS NERN OK INTO SWRN MO DURING THE OVERNIGHT HOURS.
LOW LEVEL WARM ADVECTION MAY INDUCE ELEVATED THUNDERSTORMS WITHIN A
MODESTLY SHEARED ENVIRONMENT THAT WOULD SEEM SOMEWHAT SUPPORTIVE OF
ROBUST UPDRAFTS GIVEN THE STEEP MID LEVEL LAPSE RATES. FOR THIS
REASON WILL MAINTAIN 5 PERCENT SEVERE PROBS TO ACCOUNT FOR THE
POSSIBILITY OF ISOLATED HAIL DURING THE LATTER HALF OF THE PERIOD.

...FL...

20/00Z SOUNDING FROM KEY DEPICTED A FAIRLY BUOYANT PROFILE WITH
500MB TEMPERATURES ON THE ORDER OF MINUS 8C WEDNESDAY EVENING.
ALTHOUGH THE NAM SUGGESTS POOR LAPSE RATES WILL BE NOTED ACROSS
SOUTH FL THURSDAY GFS SOUNDINGS ARE LIKELY MORE REPRESENTATIVE
ACROSS THIS REGION WITH MLCAPE IN EXCESS OF 1000 J/KG...ALTHOUGH
PROFILES ARE QUITE MOIST THROUGH A DEEP LAYER. LATEST THINKING IS
BOUNDARY LAYER HEATING WILL CONTRIBUTE TO DESTABILIZATION/CONVECTIVE
DEVELOPMENT BY EARLY AFTERNOON AS TEMPERATURES WARM INTO THE 80S.
WHILE A FEW STORMS MAY PRODUCE MARGINALLY SEVERE HAIL/WIND MOST
STORMS SHOULD REMAIN BELOW SEVERE LEVELS.
