AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE MOBILE AL
338 PM CDT SUN SEP 30 2012
.AVIATION [00Z TAF ISSUANCE]...BROKEN LINE OF SHRA/TSRA TO TRACK
EASTWARD ACROSS THE CENTRAL GULF COAST THIS EVENING WITH IFR/MVFR
CIGS/VSBYS. COULD BE SOME LIFR VSBY AT TIMES IN ANY HEAVIER TSRA.
LOW PRESSURE OVER THE MS DELTA WILL MAINTAIN SOUTHERLY FLOW AROUND
15 KTS ON AVERAGE TONIGHT...WITH HIGHER GUSTS IN TSRA. WINDS BECOMING
MORE SOUTHWEST BY 01.18Z AS THE LOW LIFTS NORTH NORTHEASTWARD. /10
/PREVIOUS DISCUSSION / 338 PM CDT SUN SEP 30 2012 /
.SHORT TERM (TONIGHT THROUGH MONDAY NIGHT)...1000 MB SFC LOW ANALYZED
OVER S CTL LOUISIANA THIS AFTERNOON WITH A WARM FRONT EXTENDING EAST
INTO SOUTH CENTRAL ALABAMA...JUST ON THE NORTHERN BORDER OF OUR
FORECAST AREA. THE ATTENDANT COLD FRONT EXTENDS FROM THE LOW SOUTH
INTO THE GULF...APPROACHING LAFAYETTE LA THIS AFTN. ONE AREA OF
SHOWERS AND THUNDERSTORMS EAST OF I-65 WILL AFFECT S CTL AL AND THE
NW FL PANHANDLE ZONES THROUGH THE REST OF THE AFTERNOON...MOVING EAST
OF THE FORECAST AREA BY THIS EVENING. OUR ATTENTION THEN TURNS TOWARD
THE CONVECTIVE ACTIVITY OVER LA/MS BEING GENERATED JUST AHEAD OF THE
SFC LOW AND COLD FRONT. THIS ACTIVITY WILL AFFECT THE WESTERN ZONES
THROUGH THIS EVENING...THEN AFFECTING AREAS EAST OF I-65 OVERNIGHT.
THE MAIN CONCERN WITH THIS CONVECTION IS THE POTENTIAL FOR ISOLATED
SEVERE STORMS. 0-1KM STORM RELATIVE HELICITY VALUES ARE INCREASING
ACROSS SE MS THIS AFTN AS SFC WINDS BACK AHEAD OF THE SFC LOW AND THE
LOW LEVEL JET INCREASES TO AROUND 35 KT. THIS PRODUCES 0-1KM SRH OF
200-250 M2/S2 OVER SE MS...SUPPORTIVE FOR ROTATING THUNDERSTORMS. THE
MAIN LIMITING FACTOR IS WEAK INSTABILITY ACROSS THE AREA.
HOWEVER...TEMPS HAVE BEEN ABLE TO REACH NEAR 80 IN THE WAKE OF THE
MORNING CONVECTION...WHICH HAS RESULTED IN MLCAPES RISING TO 500-1000
J/KG. THEREFORE...ISOLATED TORNADOES CANNOT BE RULED OUT. A TORNADO
WATCH IS IN EFFECT UNTIL 8PM FOR SE MS. THE CHANCE OF ISOLATED SEVERE
WILL SHIFT EAST TONIGHT AS THE LOW LEVEL JET INCREASES TO 40-45 KT.
MLCAPES ARE LIKELY TO HOVER AROUND 500 J/KG OVER THE SOUTHERN HALF OF
THE AREA...MAINLY DUE TO INCREASING WARM AIR ADVECTION OFFSETTING
NOCTURNAL COOLING. SO WHILE INSTABILITY WILL REMAIN LIMITED...THERE
WILL BE JUST ENOUGH TO SUPPORT AN ISOLATED TORNADO THREAT. HAVE
UPDATED THE HAZARDOUS WEATHER OUTLOOK TO REFLECT THIS.
A WELL PRONOUNCED DRY SLOT...SEEN ON WATER VAPOR IMAGERY...WILL MAKE
STEADY EASTWARD PROGRESS TONIGHT THROUGH MONDAY MORNING...WHICH WILL
SHUT OFF THE DEEP CONVECTION OVER THE WESTERN ZONES OVERNIGHT...WITH
DEEP CONVECTION SHIFTING EAST OF THE CWA BY MID TO LATE MONDAY
MORNING.
THE COLD FRONT WILL MOVE THROUGH THE WESTERN ZONES MONDAY MORNING AND
PUSH EAST OF THE CWA BY MONDAY AFTERNOON. COOLER AND DRIER AIR WILL
FILTER INTO THE AREA. ABUNDANT LOW LEVEL STRATUS IS EXPECTED THROUGH
THE DAY MONDAY IN THE WAKE OF THE FRONT AS THE 925-850 MB TROUGH
REMAINS TO OUR WEST. COULD SEE A FEW SHOWERS OVER THE FAR NORTHERN
COUNTIES DUE TO SUFFICIENT WRAP AROUND MOISTURE. HIGHS WILL BE
REACHED EARLY ON IN THE WESTERN ZONES...WITH ONLY MID TO UPPER 70S
EXPECTED. LOW 80S ARE EXPECTED EAST OF I-65 DUE TO THE LATER ARRIVAL
OF THE COLD FRONT. CLOUDS BEGIN TO CLEAR OUT MON NIGHT WITH LOWS IN
THE MID 50S TO LOWER 60S EXPECTED. 34/JFB
&&
.LONG TERM (TUESDAY THROUGH SUNDAY)...SLIGHTLY BELOW NORMAL
TEMPERATURES ON TUESDAY WILL MODERATE TO NEAR NORMAL LEVELS FOR MID
TO LATE WEEK AS WEAK HIGH PRESSURE OVER THE SOUTHERN APPALACHIANS
WEAKENS AND A LIGHT SOUTHERLY FLOW RETURNS TO THE AREA. TREMENDOUS
DIFFERENCES EXIST BETWEEN THE GFS/ECMWF FOR THIS WEEKEND. THE GFS
CONTINUES TO SHOW ANOTHER COLD FRONT PUSHING THROUGH FRIDAY NIGHT
WHILE THE ECMWF ONLY SHOWS THE FRONT APPROACHING THE MIDSOUTH/TN
VALLEY BY SUNDAY. GIVEN SUCH STARK DIFFERENCES THIS FAR OUT...DID NOT
MAKE MANY CHANGES TO THE FORECAST...AND STAYED CLOSE TO GUIDANCE.
34/JFB
&&
.MARINE...SHOWERS AND THUNDERSTORMS BECOMING NUMEROUS AT TIMES WILL
CONTINUE TO FORM AND MOVE EASTWARD OVER THE MARINE AREA THROUGH
MIDDAY MONDAY...AHEAD OF A COLD FRONT APPROACHING FROM THE WEST. A
MODERATE TO STRONG SOUTHERLY WIND FLOW CAN BE EXPECTED THROUGH MIDDAY
MONDAY...BECOMING WEST AND REMAINING GUSTY IN THE WAKE OF THE FRONT
LATE MONDAY THROUGH MIDDAY TUESDAY. A LIGHT TO MODERATE SOUTHERLY
FLOW...MOSTLY DURING THE AFTERNOON AND EARLY EVENING HOURS CAN BE
EXPECTED LATE TUESDAY THROUGH THURSDAY AS HIGH PRESSURE REBUILDS OVER
THE EASTERN AND NORTH CENTRAL GULF. 32/EE
&&
.FIRE WEATHER...PERIODS OF SHOWERS AND THUNDERSTORMS WILL CONTINUE
THROUGH TONIGHT AHEAD OF AN APPROACHING COLD FRONT. THE COLD FRONT
WILL MOVE THROUGH THE REGION ON MONDAY...BRINGING DRIER AND COOLER
AIR TO THE REGION. BOUNDARY LAYER MIXING WILL CONTINUE TONIGHT AHEAD
OF THE FRONT...WITH GOOD DISPERSIONS EXPECTED MONDAY AND TUESDAY
WITH STRONG WESTERLY TRANSPORT WINDS EXPECTED IN THE WAKE OF THE
FRONT. RELATIVE HUMIDITY VALUES WILL REMAIN WELL ABOVE CRITICAL
THRESHOLDS THROUGH THE FORECAST PERIOD.

THIS HAZARDOUS WEATHER OUTLOOK IS FOR PORTIONS OF SOUTH CENTRAL
ALABAMA...SOUTHWEST ALABAMA...NORTHWEST FLORIDA AND SOUTHEAST
MISSISSIPPI.
.DAY ONE...THIS AFTERNOON AND TONIGHT
A DEEPENING AREA OF LOW PRESSURE OVER SOUTH CENTRAL LOUISIANA WILL
TRACK NORTHEAST INTO NORTHERN ALABAMA AND MISSISSIPPI BY MONDAY.
PERIODS OF SHOWERS AND THUNDERSTORMS WILL CONTINUE INTO TONIGHT
AHEAD OF THE LOW AND ITS ASSOCIATED COLD FRONT. SOME OF THE RAIN
WILL BE HEAVY AT TIMES AND MAY RESULT IN LOCALIZED FLOODING...
ESPECIALLY IN URBAN AND LOW LYING AREAS.
AS THE SURFACE LOW APPROACHES...LOW LEVEL WINDS WILL INCREASE ACROSS
THE REGION...BRINGING A SLIGHT RISK OF ISOLATED SEVERE STORMS. THE
MAIN RISKS FROM ANY SEVERE WEATHER WILL BE LOCALIZED DAMAGING WIND
GUSTS AND A BRIEF TORNADO. THE GREATEST POTENTIAL FOR ISOLATED
SEVERE WEATHER WILL BE LOCATED ACROSS INLAND SOUTHEAST MISSISSIPPI
THIS AFTERNOON AND EARLY EVENING WHERE A TORNADO WATCH IS IN EFFECT
UNTIL 8 PM. THE SEVERE WEATHER THREAT WILL GRADUALLY SHIFT EAST AS
THE NIGHT PROGRESSES.
.DAYS TWO THROUGH SEVEN...MONDAY THROUGH SATURDAY
SHOWERS AND THUNDERSTORMS WILL GRADUALLY MOVE EAST OUT OF THE AREA BY
MONDAY AFTERNOON. A FEW STRONG STORMS ALONG WITH HEAVY RAINFALL WILL
REMAIN POSSIBLE EAST OF INTERSTATE 65 EARLY MONDAY MORNING.
.SPOTTER INFORMATION STATEMENT...
ACTIVATION OF SKYWARN SEVERE STORM SPOTTER NETWORKS IS REQUESTED IN
SUPPORT OF THE TORNADO WATCH OVER INLAND SOUTHEAST MISSISSIPPI.
