DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0634 PM CST TUE NOV 20 2007

VALID 210100Z - 211200Z

..NO SVR TSTM AREAS FORECAST...

..GREAT LAKES TO LOWER MS VALLEY...

EVENING WATER VAPOR IMAGERY SHOWS POTENT UPPER TROUGH DIGGING SEWD
THROUGH THE WRN INTERMOUNTAIN REGION WITH WEAKER...LOWER LATITUDE
IMPULSES TRANSLATING MORE SLOWLY NEWD THROUGH NRN MEXICO AND TX. IN
THE LOW LEVELS...SURFACE LOW CURRENTLY OVER NRN MO IS FORECAST TO
DEVELOP NEWD INTO NRN IND OVERNIGHT WITH TRAILING...STRONG COLD
FRONT PUSHING SEWD/SWD INTO THE MID MS VALLEY AND SRN PLAINS.

CLUSTERS OF TSTMS HAVE OCCURRED THIS AFTERNOON OVER PARTS OF SERN TX
WITH ADDITIONAL STORMS ONGOING AS OF 00Z JUST S/SW OF THE LOWER RIO
GRANDE VALLEY WITHIN A MOIST AND MODERATELY UNSTABLE AIR MASS PER
00Z CRP/BRO SOUNDINGS. THE POTENTIAL FOR AT LEAST ISOLATED TSTM
DEVELOPMENT WILL CONTINUE OVERNIGHT FROM THE LOWER MS VALLEY SWWD
INTO S TX OVERNIGHT IN ASSOCIATION WITH ABOVEMENTIONED IMPULSES
TRANSLATING NEWD.

ELSEWHERE...SHORT TERM MODEL GUIDANCE REMAINS CONSISTENT IN
INDICATING THAT ELEVATED TSTMS WILL DEVELOP TONIGHT IN IMMEDIATE
WAKE OF COLD FRONT FROM THE MIDWEST INTO THE OZARK PLATEAU AS
LEADING EDGE OF STRONGER FORCING FOR ASCENT ASSOCIATED WITH WRN U.S.
UPPER TROUGH BEGINS TO OVERSPREAD FRONTAL ZONE. MODEL FORECAST
SOUNDINGS INDICATE MUCAPES APPROACHING 1000-1200 J/KG...NAMELY FROM
THE OZARKS SWWD...HOWEVER THE MARGINAL CLOUD BEARING SHEAR AND
MID-LEVEL LAPSE RATES SHOULD LIMIT ANY SEVERE WEATHER POTENTIAL.

UPWARD TO 1500 J/KG CENTRAL TX...THUNDERSTORMS SHOULD GRADUALLY
BECOME MORE WIDESPREAD REMAINDER OF AFTERNOON MUCH OF CENTRAL/ERN TX
LIMITED SHEAR AND LAPSE RATES GENERALLY LESS THAN 7C/KM FAVOR STORMS

THUNDERSTORMS EXPECTED TO STEADILY INCREASE BEGINNING BY THIS
EVENING FROM NRN MO NEWD ACROSS NRN IL AND THEN INTO MI TONIGHT

DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1116 AM CST TUE NOV 20 2007

VALID 211200Z - 221200Z

..THERE IS A SLGT RISK OF SVR TSTMS CENTERED OVER THE MID SOUTH/TN
VALLEY REGION...

..SYNOPSIS...
LARGE COLD TROUGH SHIFTS EWD INTO MIDDLE OF THE CONUS WED WITH A
STRENGTHENING MID/UPPER LEVEL JET FROM THE CENTRAL PLAINS INTO MID
MS VALLEY.

STRONG COLD FRONT BY 12Z WED WILL BE LOCATED ACROSS MID MS VALLEY
SWWD THRU CENTRAL OK TO SERN NM. FRONT PLUNGES RAPIDLY SWD THRU TX
REACHING THE COAST BY 06Z. FRONTAL MOVEMENT FURTHER E WILL BE
SOMEWHAT SLOWER INITIALLY AS A WAVE DEVELOPS SERN MO REGION DURING
THE AFTERNOON. THIS PORTION OF THE FRONT PICKS UP SPEED OVERNIGHT
AS SURFACE LOW TRACKS NEWD ACROSS PA BY 12Z THU.

WITH THE STRONGEST MID/UPPER WIND FIELDS AND JET DYNAMICS REMAINING
ON THE COOL SIDE OF THE FRONTAL ZONE...SEVERE POTENTIAL WILL BE
PRIMARILY SUPPORTED BY THE AMOUNT OF INSTABILITY THAT CAN DEVELOP IN
THE WARM SECTOR DURING THE DAY.

..TN VALLEY SWWD INTO LOWER MS VALLEY...

AN UNSEASONABLY MOIST AIR MASS WILL HAVE SPREAD FROM SRN PLAINS NEWD
ACROSS MS VALLEY INTO TN AND SRN OH VALLEYS S OF OH RIVER BY WED AM.
WITH LOW/MID 60F DEWPOINTS SPREADING AS FAR N AS WRN TN/KY AHEAD OF
FRONT DURING THE DAY INSTABILITY WILL BE SUFFICIENT FOR
THUNDERSTORMS INCREASING IN BOTH NUMBER AND INTENSITY ALONG/AHEAD OF
THE COLD FRONT. AS THE WIND FIELDS AT ALL LEVELS STEADILY INCREASE
WITH APPROACH OF TROUGH AND MID/UPPER JET...STORMS SHOULD GRADUALLY
DEVELOP INTO LINE SEGMENTS AND POSSIBLY ISOLATED SUPERCELLS. WHILE
DEEP LAYER SHEAR EXPECTED TO REMAIN GENERALLY 40KTS OR LESS IN THE
WARM SECTOR...MLCAPES TO NEAR 1000 J/KG COUPLED WITH LOW LFC'S AND
20-25KT OF SFC-1KM SHEAR WOULD SUPPORT TORNADO POTENTIAL WITH ANY
SUPERCELL THAT IS ABLE TO DEVELOP.

INITIAL SEVERE THREAT WILL LIKELY BE MID MS/WRN TN VALLEY AREA IN
REGION OF STRONGEST ASCENT AND SHEAR FIRST PART OF FORECAST PERIOD.
THUNDERSTORMS INCLUDING A SEVERE POTENTIAL WILL THEN DEVELOP E AHEAD
OF FRONT FROM OH RIVER SWD THRU THE EVENING.

FURTHER S INTO ERN TX...WHERE DEWPOINTS TO NEAR 70F AND STRONGER
HEATING IS EXPECTED THE AIR MASS SHOULD BECOME MODERATELY UNSTABLE
BY MID AFTERNOON WITH MLCAPES AOA 2000 J/KG. WHILE DEEP LAYER SHEAR
WILL BE WEAKER SRN PORTION OF SLIGHT RISK...THE COMBINATION OF
GREATER INSTABILITY AND STEEPER LOW LEVEL LAPSE RATES WILL BE
SUFFICIENT FOR AT LEAST ISOLATED SEVERE THUNDERSTORMS ALONG AND
AHEAD OF ADVANCING COLD FRONT. 20-25KT OF LOW LEVEL SHEAR NOTED ON
MODEL SOUNDINGS FROM ERN TX INTO CENTRAL MS WED AFTERNOON/EVENING
SUGGEST ROTATING STORMS ARE POSSIBLE ENHANCING POTENTIAL FOR BOTH
LARGE HAIL AND DOWNBURST WINDS.

..NO SVR TSTM AREAS FORECAST...

COLD TROUGH WILL AMPLIFY SEWD ACROSS NRN AND CENTRAL ROCKIES WITH
RISING HEIGHTS ERN U.S. LEADING TO AN INCREASING SWLY FLOW MIDDLE OF
THE CONUS THIS FORECAST PERIOD. STRONG COLD FRONT SURGING SEWD
CENTRAL HIGH PLAINS IN ADVANCE OF UPPER TROUGH PRECEEDED BY
UNSEASONABLY WARM/MOIST AIR MOVING NEWD FROM THE SRN PLAINS INTO THE
MID MS VALLEY.

WEAK UPPER TROUGH OVER MEXICO WILL TRACK EWD ACROSS TX INTO LWR MS
VALLEY TODAY IN ADVANCE OF STRONG UPSTREAM SYSTEM.

THUNDERSTORM POTENTIAL IN WARM SECTOR TODAY WILL BE LIMITED GIVEN
THE GENERALLY WEAK LAPSE RATES AND THE UPPER SUPPORT WITH THE
ROCKIES TROUGH REMAINING MAINLY ON THE COLD SIDE OF THE FRONT.

ISOLD/SCTD TSTMS WILL BE POSSIBLE THIS AFTERNOON OVER SRN/ERN TX
INTO LA AS FORCING FOR ASCENT WITH LEAD IMPULSE EJECTING WITH
MEXICAN TROUGH OVERSPREADS REGION DURING MAX HEATING.

ISOLD TSTMS MAY FORM TONIGHT IN ANAFRONTAL ENVIRONMENT FROM
CNTRL/SRN MI SW INTO THE OZARKS AND POSSIBLY NE OK. OTHER
SHOWERS/POSSIBLE STORMS MAY FORM LATE IN THE PERIOD OVER AR ON
LEADING EDGE OF STRONGER THETA-E ADVECTION ALONG 40 KT SWLY LLJ.

EWD ACROSS THE SERN CONUS AHEAD OF THE FRONT...EVENTUALLY MOVING E
OFF THE ATLANTIC AND GULF COASTS WHILE LINGERING OVER THE FL

WHILE THE LACK OF INSTABILITY SHOULD LIMIT THE OVERALL SEVERE
THREAT...DEEP-LAYER WIND FIELD APPEARS SUFFICIENT FOR A FEW

STRONGER FLOW ALOFT SHOULD REMAIN WELL THE COOL SIDE OF THE FRONT.
HOWEVER...A FEW OF THE STRONGER/MORE PERSISTENT STORMS/LINE SEGMENTS
COULD PRODUCE LOCALLY STRONG/GUSTY WINDS AND PERHAPS SOME MARGINAL
HAIL. GREATER SEVERE THREAT -- THOUGH STILL LIMITED -- COULD PROVE
TO BE ISOLATED TORNADOES...AS SLY/SSWLY BOUNDARY-LAYER FLOW BENEATH
25 TO 35 KT WSWLY LOW-LEVEL JET ACROSS THE MID SOUTH/OH VALLEY
REGION SHOULD YIELD 20 TO 30 KT 0-1 KM SHEAR. WITH LOW CLOUD BASES
ALSO ANTICIPATED...THREAT APPEARS GREAT ENOUGH WHEN COMBINED WITH
WIND POTENTIAL TO INITIATE A SLIGHT RISK THIS FORECAST...CENTERED
OVER THE MID SOUTH/TN VALLEY REGION.

SPC AC 200538

DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1138 PM CST MON NOV 19 2007

VALID 201200Z - 211200Z

..NO SVR TSTM AREAS FORECAST...

..SYNOPSIS...

STRONG SHORT WAVE TROUGH CURRENTLY OVER THE PACIFIC NW IS FORECAST
TO FURTHER INTENSIFY WHILE TRANSLATING ESEWD THROUGH THE NRN AND
CNTRL ROCKIES. AS THIS OCCURS...STRENGTHENING SWLY FLOW IN THE
LOWER LATITUDES WILL RESULT IN THE NEWD PROGRESSION OF VORTICITY
MAXIMUM NOW OVER NRN MEXICO INTO THE LOWER MS VALLEY. IN THE LOW
LEVELS...SURFACE LOW INITIALLY OVER ERN KS WILL DEVELOP NEWD INTO
THE SRN GREAT LAKES BY WEDNESDAY MORNING WITH TRAILING COLD FRONT
PUSHING EWD THROUGH THE MID MS VALLEY...AND SWD THROUGH THE CNTRL
INTO SRN PLAINS.

..LOWER MI SWD TO ERN TX/LA...

SWLY LLJ WILL MAINTAIN A RELATIVELY MOIST LOW-LEVEL AIR MASS AHEAD
OF SURFACE COLD FRONT WITH DEWPOINTS RANGING FROM LOWER/MID 50S OVER
THE SRN GREAT LAKES TO MID/UPPER 60S ALONG THE TX/LA COASTS.
HOWEVER...FORECAST SOUNDINGS INDICATE THAT MID-LEVEL LAPSE RATES
WILL REMAIN QUITE WEAK...EFFECTIVELY LIMITING MLCAPES TO AOB 500
J/KG WITHIN WARM SECTOR.

ISOLATED/SCATTERED TSTMS WILL BE POSSIBLE THIS AFTERNOON OVER PARTS
OF SRN/ERN TX INTO LA AS FORCING FOR ASCENT ASSOCIATED WITH EJECTING
NRN MEXICO VORTICITY MAXIMUM ACTS ON DESTABILIZING AIR MASS.
OTHERWISE...SCATTERED TSTMS ARE EXPECTED TO DEVELOP TONIGHT IN
ANAFRONTAL FLOW REGIME FROM CNTRL/SRN MI SWWD THROUGH THE OZARKS AND
PERHAPS ERN OK/AR AS LEADING EDGE OF GREATER HEIGHT FALLS/FORCING
FOR ASCENT ATTENDANT TO ROCKIES UPPER TROUGH OVERSPREADS SURFACE
COLD FRONT. NO SEVERE WEATHER IS EXPECTED.
