DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
0748 PM CDT MON OCT 22 2007

VALID 230100Z - 231200Z

..THERE IS A SLGT RISK OF SVR TSTMS ACROSS PORTIONS OF SERN
LA...ERN MS...WRN AL AND THE WRN FL PANHANDLE...

..CENTRAL GULF STATES...
A HIGHLY AMPLIFIED UPPER TROUGH WILL CONTINUE TO MOVE EWD ACROSS
ONTARIO AND THE CENTRAL U.S. TONIGHT. THE SRN EXTENT OF THIS TROUGH
SHOULD BE EVOLVING INTO A CUT-OFF LOW AS IT APPROACHES ERN OK/ERN TX
AND WRN AR/NWRN LA BY 12Z TUESDAY. ATTENDANT COLD FRONT WITH THE
LARGE UPPER TROUGH WILL MAINTAIN EWD MOVEMENT THROUGH THE OH/TN AND
LOWER MS VALLEYS TONIGHT. SURFACE LOW LOCATED ALONG THIS BOUNDARY
IN NRN MS WILL TRACK NEWD WHILE TRAILING PART OF COLD FRONT SHOULD
EXTEND SWD ALONG THE MS/AL BORDER INTO THE GULF OF MEXICO BY END OF
FORECAST PERIOD.

LOW LEVEL SLY WINDS OF 40-50 KT ALONG AND E OF THE FRONT INTO THE
CENTRAL GULF COAST STATES WILL ALLOW RICH MOISTURE TO SPREAD FARTHER
INLAND TONIGHT...MAINTAINING LOW LCLS AND FAVORABLE LOW LEVEL SHEAR
FOR A CONTINUED TORNADO THREAT. SSWLY MID LEVEL WINDS WILL ALSO
STRENGTHEN TO 50-60 KT AS THE UPPER TROUGH SHIFTS EWD RESULTING IN
INCREASING EFFECTIVE BULK SHEAR TO SUPPORT A CONTINUED POTENTIAL FOR
ORGANIZED STORMS BOTH ALONG AND IN ADVANCE OF THE FRONT. TORNADO
THREAT IS EXPECTED TO CONTINUE THIS EVENING ACROSS FAR SERN LA INTO
SERN MS/SWRN AL AND WRN FL PANHANDLE...ESPECIALLY WITH DISCRETE
STORMS FORMING AHEAD OF THE COLD FRONT. THIS THREAT MAY SPREAD
FARTHER NWD INTO EAST CENTRAL MS/WRN AL TONIGHT ALONG AXIS OF LLJ
WHICH WILL PROMOTE STRONG LOW LEVEL SHEAR FOR ISOLATED ROTATING
STORMS.

CONCERNING...TORNADO WATCH 729...

VALID 230029Z - 230200Z

THE SEVERE WEATHER THREAT FOR TORNADO WATCH 729 CONTINUES.

SINCE 23Z SSELY SURFACE WINDS ALONG WITH UPPER 70 DEWPOINTS HAVE
INCREASED COASTAL AREAS OF SERN MS/MOBILE BAY. ALSO THE MOB-88D VAD
WINDS INDICATES THE LOW LEVEL SHEAR HAS BECOME VERY FAVORABLE FOR
ROTATING SUPERCELLS WITH SFC-1KM SHEAR FROM 25-30KT.

MOB RADAR INDICATES SEVERAL SUPERCELLS HAVE DEVELOPED AND ARE MOVING
NWD FROM NRN JACKSON COUNTY INTO GEORGE COUNTIES MS EWD INTO NRN
MOBILE COUNTY AL. THUNDERSTORMS ARE INCREASING FROM HARRISON COUNTY
MS SSWWD TO COASTAL PLAQUEMINES PARISH AHEAD OF MAIN BAND OF STORMS
TO THE W. THESE CELLS ARE IN A VERY FAVORABLE REGION FOR ROTATION
AS THEY MOVE INLAND THRU SERN MS NEXT COUPLE OF HOURS. ANY ROTATING
STORM IN THIS WARM SECTOR HAS POTENTIAL OF PRODUCING A
TORNADO/ISOLATED WIND DAMAGE.

COASTAL WATERS

EFFECTIVE THIS MONDAY AFTERNOON AND EVENING FROM 505 PM UNTIL
1100 PM CDT.

TORNADOES...HAIL TO 1 INCH IN DIAMETER...THUNDERSTORM WIND GUSTS
TO 70 MPH...AND DANGEROUS LIGHTNING ARE POSSIBLE IN THESE AREAS.

THE TORNADO WATCH AREA IS APPROXIMATELY ALONG AND 50 STATUTE
MILES NORTH AND SOUTH OF A LINE FROM 15 MILES WEST OF HOUMA
LOUISIANA TO 30 MILES SOUTH SOUTHEAST OF EVERGREEN ALABAMA. FOR
A COMPLETE DEPICTION OF THE WATCH SEE THE ASSOCIATED WATCH
OUTLINE UPDATE (WOUS64 KWNS WOU9).

REMEMBER...A TORNADO WATCH MEANS CONDITIONS ARE FAVORABLE FOR
TORNADOES AND SEVERE THUNDERSTORMS IN AND CLOSE TO THE WATCH
AREA. PERSONS IN THESE AREAS SHOULD BE ON THE LOOKOUT FOR
THREATENING WEATHER CONDITIONS AND LISTEN FOR LATER STATEMENTS
AND POSSIBLE WARNINGS.

DISCUSSION...SMALL AND ISOLATED SUPERCELLS ARE DRIFTING ONSHORE THIS
AFTERNOON FROM SOUTHEASTERN LA TO MOBILE BAY. PRESENCE OF AMPLE
MOISTURE...STRONG VERTICAL SHEAR...AND APPROACHING UPPER TROUGH
SUPPORT A RISK OF ISOLATED TORNADOES THROUGH THE EVENING HOURS.

AVIATION...TORNADOES AND A FEW SEVERE THUNDERSTORMS WITH HAIL
SURFACE AND ALOFT TO 1 INCH. EXTREME TURBULENCE AND SURFACE WIND
GUSTS TO 60 KNOTS. A FEW CUMULONIMBI WITH MAXIMUM TOPS TO 500.

HISTORY HAS BEEN FOR ROTATIONS TO WEAKEN AS THEY MOVE ONSHORE WHERE
AIR MASS A LITTLE LESS UNSTABLE. HOWEVER WITH THE TREND CONTINUING
FOR HIGHER DEWPOINTS WORKING INLAND...THE POTENTIAL FOR SUPERCELLS
ALONG WITH ISOLATED TORNADOES EXPECTED TO INCREASE DURING THE NEXT

BOUNDARY LAYER AIRMASS OVER ERN LA INTO WCNTRL MS HAS DESTABILIZED

BUOYANT AND WILL CONTINUE TO FREELY CONVECT THROUGH THE AFTERNOON

ADVECTION ZONE FROM SERN LA INTO SRN MS. LATEST THINKING IS
WIDESPREAD CONVECTION WILL OCCUR ACROSS THE ERN HALF OF LA INTO MS
WELL INTO THE OVERNIGHT HOURS. VERTICAL SHEAR PROFILES CERTAINLY
SUPPORT STORM ROTATION AND POSSIBLE SUPERCELL DEVELOPMENT...HOWEVER
NUMEROUS STORM MERGERS AND CLUSTERING WITHIN RELATIVELY WEAK

VALID 221858Z - 222030Z

A GRADUAL INCREASE IN THUNDERSTORM DEVELOPMENT IS EXPECTED THROUGH
THE PEAK AFTERNOON HEATING. TRENDS ARE BEING MONITORED FOR AN
INCREASING SEVERE THREAT AND THE POSSIBILITY OF A WW.

IN A RELATIVELY NARROW PRE-FRONTAL CORRIDOR ACROSS THE LOWER
MISSISSIPPI VALLEY...BREAKS IN CLOUD COVER HAVE ALLOWED SUFFICIENT
SURFACE HEATING TO REDUCE INHIBITION TO NEGLIGIBLE LEVELS. AND
THIS...IN CONJUNCTION WITH LARGE-SCALE FORCING FOR UPWARD VERTICAL
MOTION ASSOCIATED WITH WEAK WARM ADVECTION...APPEARS TO BE
SUPPORTING INCREASING THUNDERSTORM ACTIVITY ACROSS SOUTH CENTRAL
LOUISIANA INTO SOUTHWESTERN MISSISSIPPI. WHILE THIS IS STILL
GENERALLY TO THE NORTH OF EXTENSIVE CONVECTIVE DEVELOPMENT OVER THE
NORTH CENTRAL GULF OF MEXICO INTO CENTRAL GULF COASTAL AREAS...WHICH
IS CUTTING OFF INFLUX OF MID/UPPER 70S F DEW POINTS INTO INLAND
AREAS...DEW POINTS ACROSS THE LOWER MISSISSIPPI VALLEY ARE GENERALLY
IN THE LOWER 70S.

GIVEN AT LEAST MODEST CLOCKWISE-CURVED HODOGRAPHS BENEATH 20-30 KT
SOUTHERLY 850 FLOW...THE BOUNDARY LAYER WITH HIGH MOISTURE CONTENT
AND HIGH RELATIVE HUMIDITIES APPEARS FAVORABLE FOR THE DEVELOPMENT
OF ISOLATED TORNADOES. MIXED LAYER CAPE IS ONLY ON THE ORDER OF 500
J/KG DUE TO WEAK MID-LEVEL LAPSE RATES AHEAD SLOWLY DIGGING UPSTREAM
TROUGH. BUT...DEEP LAYER SHEAR BENEATH 50 KT CYCLONIC 500 MB FLOW
IS STRONG AND FAVORABLE FOR SUPERCELLS...AS ACTIVITY SPREADS NORTH
NORTHEASTWARD THIS AFTERNOON.

DAY 2 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1215 PM CDT MON OCT 22 2007

VALID 231200Z - 241200Z

..NO SVR TSTM AREAS FORECAST...

..CENTRAL GULF COAST...

LATEST SHORT RANGE MODEL GUIDANCE SUGGEST UPPER LOW OVER THE SRN
PLAINS DAY1 WILL MEANDER INTO THE ARKLATEX REGION TUESDAY BEFORE
STALLING. THIS SLOW EWD DRIFT WILL NOT PROVE TERRIBLY CONDUCIVE FOR
ORGANIZED SEVERE THUNDERSTORM DEVELOPMENT ALONG/AHEAD OF COLD FRONT
ACROSS MS/AL/FL PANHANDLE.

ALTHOUGH VERTICAL SHEAR PROFILES WILL BE SUFFICIENTLY STRONG FOR
ORGANIZED UPDRAFTS...FORECAST SOUNDINGS ACROSS THE CENTRAL GULF
STATES SUGGEST MID LEVEL LAPSE RATES WILL REMAIN MOIST
ADIABATIC...WITH ROUGHLY 500-1000 J/KG MLCAPE. IN THE ABSENCE OF
MEANINGFUL LARGE SCALE ASCENT ACROSS THE WARM SECTOR...AND THE
LIKELIHOOD FOR EXTENSIVE CLOUDINESS...THE PROSPECT FOR ROBUST
THUNDERSTORM ACTIVITY APPEARS LIMITED. HOWEVER...VERY MOIST
BOUNDARY LAYER CONDITIONS AND AMPLE DEEP LAYER SHEAR DO WARRANT AT
LEAST LOW PROBABILITIES FOR ISOLATED DAMAGING WIND GUSTS OR PERHAPS
A TORNADO...ESPECIALLY DURING THE AFTERNOON HOURS WHEN BOUNDARY
LAYER HEATING WILL BE MAXIMIZED.

SPC AC 221629

DAY 1 CONVECTIVE OUTLOOK
NWS STORM PREDICTION CENTER NORMAN OK
1129 AM CDT MON OCT 22 2007

VALID 221630Z - 231200Z

..THERE IS A SLGT RISK OF SVR TSTMS ACROSS THE LOWER MS VALLEY
THROUGH TONIGHT...

..LOWER MS VALLEY AREA THROUGH TONIGHT...
THE DEEP MID LEVEL TROUGH OVER W TX/OK WILL MOVE EWD AND EVOLVE INTO
A CLOSED LOW OVER SE OK/NE TX BY LATE TONIGHT. AN ASSOCIATED WEAK
SURFACE CYCLONE NOW NEAR SHV WILL MOVE ENEWD TOWARD THE MS/TN/AL
BORDER REGION LATE TONIGHT...WHILE A TRAILING COLD FRONT PROGRESSES
EWD ACROSS LA/MS.

A MARITIME TROPICAL AIR MASS /BOUNDARY LAYER DEWPOINTS IN THE 70S/
HAS SPREAD NWD INTO CENTRAL LA AND SRN MS/AL TO THE S OF A
RETREATING MARINE FRONT...AND E OF THE COLD FRONT APPROACHING THE
TX/LA BORDER. RELATIVELY WIDESPREAD CONVECTION IS ONGOING OVER THE
N CENTRAL GULF INTO SE LA WITHIN THE SWATH OF STRONGEST MOISTURE
TRANSPORT...AND THIS CONVECTION WILL LIKELY SPREAD NNEWD THROUGH
TONIGHT WHILE GRADUALLY CONSOLIDATING INTO A BAND NEAR THE COLD
FRONT. A CORRIDOR OF STRONGER SURFACE HEATING WILL OCCUR TODAY FROM
SW MS INTO SRN LA...WHERE AFTERNOON MLCAPE VALUES WILL LIKELY REACH
1000-1500 J/KG AS SURFACE TEMPERATURES WARM INTO THE 80S. FARTHER
E/NE...THE CLOUDS/RAINFALL WILL LIMIT INSTABILITY THROUGH THE
PERIOD.

DESPITE THE MODERATE MLCAPE VALUES ACROSS SRN LA...MID LEVEL LAPSE
RATES WILL BE AOB 6 C/KM...AND LOW-LEVEL WINDS/SHEAR IN THE MOST
UNSTABLE PORTION OF THE WARM SECTOR WILL BE RATHER WEAK AS A RESULT
OF MINIMAL SURFACE CYCLOGENESIS. THE MORE FAVORABLE
SUPERCELL/TORNADO WIND PROFILES ARE EXPECTED FARTHER E ACROSS SE MS
AND AL TODAY INTO TONIGHT IN CONJUNCTION WITH THE LLJ...WHERE
INSTABILITY WILL BE MARGINAL. THEREFORE...THE OVERALL THREAT FOR
SUPERCELL TORNADOES AND/OR DAMAGING WINDS WITH EMBEDDED BOW ECHOES
IS CORRESPONDINGLY MARGINAL.
