AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE BIRMINGHAM AL
835 PM CDT TUE MAR 29 2011

.UPDATE...MESOSCALE UPDATE.

&&

.DISCUSSION...

MODEL SUITE PERFORMANCE OVER THE PAST FEW DAYS HAS NOT EXACTLY HAD A
GREAT HANDLE ON THE DEVELOPING SENSIBLE WEATHER THIS EVENING. THE
LATEST WATER VAPOR IMAGERY HAS AN UPPER TROUGH SWINGING INTO THE
SOUTHERN PLAINS WHILE SEVERAL SHORT WAVE TROUGHS RIDE THROUGH THE
SUBTROPICAL JET FLOW INTO THE GULF COAST REGION. SYNOPTIC SCALE LIFT
IS INCREASED AS THE UPPER TROUGH APPROACHES. BOTH THE RUC AND GFS
DEVELOP ENHANCED MESOSCALE LIFT ACROSS CENTRAL ALABAMA BY 1 AM BUT
IT APPEARS THE RUC MASS FIELDS ARE CLOSER TO 01Z OBSERVATIONS.
295K-300K ISENTROPIC SURFACES INDICATE DECENT LIFT AND CONVERGENCE
OVER SOUTHERN MISSISSIPPI AND LOUISIANA THAT WILL TRANSLATE INTO THE
WESTERN HALF OF CENTRAL ALABAMA BY 06Z. THE 00Z RAOB INDICATES WE
ARE MOISTURE STARVED RIGHT NOW BUT THE LOW LEVEL JET BETWEEN 2K-5K
FT WILL INCREASE TO 30 TO 35 KTS OUT OF THE SOUTHWEST AND USHER IN
PLENTY OF MOISTURE. RUC SOUNDINGS FOR WESTERN ALABAMA HAVE A
DECIDEDLY DIFFERENT LOOK THAN MODEL SOUNDINGS THE PAST FEW DAYS.
THERE WILL BE A PERIOD BEFORE SATURATION WHERE -10 TO -30 CAPE
VALUES REACH SEVERAL HUNDRED AND THIS WOULD SUPPORT SOME HAIL
PRODUCTION. SPC MESOANALYSIS HAS A CHANCE OF ELEVATED SUPERCELLULAR
STRUCTURE INTO NORTH CENTRAL MISSISSIPPI AT THIS TIME WITH
SUFFICIENT SHEAR FOR THIS ORGANIZATION. THEREFORE...HAVE ADDED THE
WESTERN THIRD OF THE AREA TO SEVERE STORM OUTLOOK...WITH LARGE HAIL
FOR THE OVERNIGHT HOURS. CONDITIONS WILL BECOME LESS FAVORABLE
EASTWARD...BUT SOME SMALL HAIL MAY STILL BE POSSIBLE.

AS THE SURFACE MOISTURE INCREASES OVERNIGHT AND A WEAK SURFACE LOW
LIFTS A WARM FRONT INTO SOUTHERN ALABAMA...THERE IS A SMALL CHANCE
THAT SOME SURFACE BASED STORMS MAY BE INITIATED IN FAR SOUTHWESTERN
AREAS GENERALLY SOUTH OF A EUTAW TO SELMA LINE. THIS WOULD ENABLE A
SMALL CHANCE OF DAMAGING WINDS AND TORNADOES IN THIS AREA...BUT
CONFIDENCE ON THE NORTHWARD PUSH OF THE MOISTURE BAND IS NOT GREAT.

RADAR DEPICTIONS WEST OF THE AREA HAVE INDICATED SEVERAL SPLITTING
STORMS WITH LEFT MOVERS BECOMING PROMINENT HAIL PRODUCERS. WILL
MONITOR THE DEVELOPMENT CLOSELY OVERNIGHT ESPECIALLY FOR ANY STORMS
THAT APPEAR ROOTED IN THE SURFACE LAYER.

.AVIATION...00Z TAF DISCUSSION.

WITH THE APPROACH OF A SHORT WAVE AND SURFACE LOW DEVELOPING ALONG
THE NORTHERN GULF COAST TONIGHT...EXPECT SHOWERS AND THUNDERSTORMS
TO AFFECT THE AREA. WATCHING DEVELOPMENT BACK TO OUR WEST IN
SOUTHWEST MS AND NORTHEAST LA. SHOWERS ARE EXPECTED TO MOVE INTO
ALABAMA JUST BEFORE MIDNIGHT AND SPREAD ACROSS THE AREA. AIRMASS
OVER CENTRAL ALABAMA IS RATHER STABLE AT THE SURFACE GIVEN THE WARM
FRONT IS STILL DOWN ALONG THE COAST. THINK THE BEST CHANCE FOR
THUNDER WILL BE AT MGM AND TOI...BUT TS CANNOT BE RULED OUT IN THE
NORTH. CONFIDENCE IS TOO LOW TO INCLUDE AT THOSE TERMINALS AT THIS
TIME. CANT RULE OUT A SHOWER OR THUNDERSTORM EARLIER THAN
FORECASTED...AND WILL HAVE TO AMEND AS NEEDED.

CLOUDS WILL REMAIN LOW ACROSS THE AREA OVERNIGHT...AND LIKELY
THROUGH MUCH OF TOMORROW. SHOWERS WILL BECOME WIDESPREAD OVERNIGHT
BECOMING A BROAD AREA OF MODERATE RAINFALL WED MORNING AHEAD OF A
COLD FRONT. EXPECT RAIN TO END AND WINDS TO SHIFT TO THE NORTHWEST
AROUND MIDDAY IN THE NORTH. EXPECT LOW CLOUDS TO REMAIN ACROSS THE
AREA BEHIND THE FRONT.

NOTICE...KEET TAF WILL HAVE (AMD LTD TO VIS WIND AND WX) AMENDED TO
THE END OF THE FORECAST UNTIL FURTHER NOTICE. THE CEILOMETER DATA
WILL BE GOING THROUGH NUMEROUS TESTS AND MONITORED FOR ACCURACY.

.PREV DISCUSSION...
/ISSUED AT 324 PM CDT TUE MAR 29 2011/.

CURRENTLY LAYING IN WAIT...WATCHING THE WARM FRONTAL BOUNDARY THAT
HAS REALLY ESTABLISHED ITSELF OVER THE NORTH CENTRAL GULF. FOR
THE MOST PART DON'T EXPECT THAT WE WILL SEE ITS EFFECTS UNTIL MUCH
LATER...IF AT ALL. HAVE A DISTINCT FEELING THAT IT WILL STRUGGLE
TO LIFT NORTHWARD WITH TIME...EVEN AS THE SURFACE LOW TRACKS
ACROSS THE SOUTHERN HALF OF THE AREA. THE CLOUDS AND DRIZZLE
CONDITIONS HAVE REALLY ACTED TO KEEP THE WEDGE AND EASTERLY FLOW
FIRMLY IN PLACE TODAY. IN OTHER WORDS...THINK THE MODELS ARE BEING
RATHER AGGRESSIVE IN BRINGING THE FRONT NORTHWARD WITH
TIME...MUCH THE SAME AS HAVING THE TEMPERATURES 5 TO 10 DEGREES
TOO WARM FOR THIS AFTERNOON. MOST LIKELY DUE TO THE VERTICAL
RESOLUTION AND SHALLOW CLOUD COVER. NONETHELESS...WILL LEAVE A FEW
COUNTIES IN THE DEEP SOUTHWEST WITH THE CHANCE OF SEEING A SEVERE
STORM...POSSIBLY ELEVATED...HAIL AND DAMAGING WINDS AS THE MAIN
THREATS. THERE IS SOME LOW LEVEL SHEAR...AND I SUPPOSE THERE COULD
BE AN OUTSIDE TOR THREAT...BUT JUST DON'T THINK WE HAVE THE LOW
LEVEL INSTABILITY TO SUSTAIN LASTING UPDRAFTS. IT MAY BE RATHER
CLOSE...HOWEVER.

THE THREAT SHOULD LINGER THROUGH THE LATE MORNING HOURS TOMORROW
ALONG THE SOUTHEASTERN COUNTIES AS THE WARM FRONT AND NOW COLD FRONT
MOVE ACROSS THE SOUTHERN CWA. AGAIN...THE MAIN THREATS STILL LOOK TO
BE WIND AND HAIL...AS THE COLD FRONT OVERTAKES THE WARM
SECTOR...MAINLY SOUTH AND EAST OF MGM. THE RAIN COULD BE MODERATE
ACROSS MUCH OF THE NORTH IN AN OVER RUNNING SCENARIO...WITH THE GULF
COAST CONVECTION KEEPING A REASONABLE CHECK ON OUR MOISTURE.

BEYOND TOMORROW AFTERNOON...WE WILL GET A MUCH NEEDED BREAK WITH
JUST SOME UPPER LEVEL TROF SHOWERS POSSIBLE ON THURSDAY AND MAYBE
OVER THE WEEKEND THOUGH I LEFT IT OUT OF THE FORECAST...OTHERWISE
NORTHWEST FLOW IS EXPECTED TO DOMINATE THROUGH THE LATE WEEKEND.
THIS WILL GIVE US QUIETER CONDITIONS...WITH THE NEXT REAL WEATHER
THREAT SHAPING UP FOR EARLY NEXT WEEK. TEMPERATURES WILL ALSO
REMAIN NEAR NORMAL..BUT WILL BEGIN TO REBOUND BY SUNDAY AND MONDAY
AS GULF RETURN FLOW CRANKS UP AHEAD OF SAID NEXT SYSTEM...WHICH
SHOULD BE ON OUR DOORSTEP BY TUESDAY.
