.DISCUSSION...

SURFACE FRONT DRAPED ACROSS NORTHERN PART OF THE CWA EARLY THIS
MORNING. HOWEVER...DO STILL HAVE SOME TSRA ACTIVITY LAGGING JUST
BEHIND VERY CLOSE TO THIS. WE ARE DEFINITELY NOT CLEAR BEHIND THE
FRONT. THIS AREA OF SHOWERS AND THUNDERSTORMS IS EXPECTED TO
PROGRESS SOUTHEASTWARD DURING THE DAY TODAY. DRY AIR WILL BE SLOW
TO SINK SOUTHWARD AS THE FRONT IS EXPECTED TO STALL JUST SOUTH OF
CENTRAL ALABAMA LATE TODAY. HOWEVER...DEPENDING ON EXACTLY WHERE
THE FRONT STALLS WILL DICTATE THE STRENGTH OF THE ACTIVITY ALONG
THE SOUTHERN HALF OF THE STATE. STILL HAVE A CHANCE...ESPECIALLY
IN THE AFTERNOON OF STRONG TO SEVERE WEATHER. ACROSS THE AFTERNOON
INSTABILITY REMAINS ACROSS THE SE WITH 1500-2000 0-3KM MU
CAPES...NOT TO MENTION -5 TO -7 LI'S. WITH UPPER 70S IN THE
FORECAST ACROSS THE SOUTH...ANY STORMS THAT POP UP CERTAINLY HAVE
THE OPPORTUNITY TO GO SEVERE.

TONIGHT INSTABILITY PARAMETERS TAPER DOWN BUT COULD STILL SEE A
FEW THUNDERSTORMS ACROSS THE SOUTHERN SECTIONS CLOSER TO STALLED
FRONT AS AN UPPER LEVEL SHORTWAVE MOVES ACROSS IN THE ZONAL FLOW.
THUS...STRONG COLD AIR ADVECTION NOT SUPPORTED BY THE UPPER FLOW.
CONVECTION SHOULD EXIT DURING EARLY MONDAY FOR THE MOST PART...
WITH DARE I SAY IT TOO LOUD...AN ACTUAL BREAK IN THE PRECIP FOR
MONDAY NIGHT INTO EARLY TUESDAY.

UPPER FLOW TURNS FROM ZONAL TO SOUTHWEST DURING TUE/WED TIME FRAME
AS A TROUGH DIGS ACROSS THE WESTERN U.S. HERE IS WHERE OUR
CONFIDENCE WANES AS THE STRENGTH AND SPEED OF THIS TROUGH IS IN
QUESTION WITH DIVERGING MODEL SOLUTIONS. COMPUTER MODELS HAVE BEEN
ADVERTISING THE LEE SIDE SURFACE TROUGH FOR SEVERAL DAYS BUT ARE
STRUGGLING TO PREDICT ITS PATH AND TIMING. WOULD NOT BE SURPRISED
TO SEE THE SLOWER SOLUTION OF DRAGGING THE PRECIP OUT THAT THE GFS
IS ADVERTISING WITH THE SURFACE LOW TRAVERSING POSSIBLY THE
NORTHERN GULF ALONG WITH STALLED BOUNDARIES ACROSS CENTRAL ALABAMA
AS THE LIKELY HOOD OF FRONTS CONTINUING TO GET THROUGH TO THE GULF
DECREASES WITH EACH SYSTEM. ALSO...UPPER FLOW DOES NOT SUPPORT
PULLING THE SURFACE SYSTEM OUT OF THE AREA UNTIL LATE IN THE WEEK.
NOW WHETHER OR NOT WE GET THE STRONG UPPER TROUGH EJECTING
VIGOROUS SHORTWAVES IN THE AREA REMAINS TO BE SEEN. HOWEVER...AM
HESITANT TO COOL THINGS OFF MID WEEK WITH THIS OTHER POSSIBILITY
ON THE TABLE. IF THE GFS VERIFIES...WE COULD BE IN STORE FOR SOME
MIGHTY ANGRY WEATHER THURSDAY AFTERNOON WITH 2500-3800 CAPES AND
LI'S -5 TO -11 JUST TO THE SW OF HERE...OUCH...DURING THE PEAK
HEATING OF THE DAY WITH PLENTY OF AVAILABLE MOISTURE AND A STALLED
BOUNDARY. NEEDLESS TO SAY AS WE GET TOWARD MID WEEK CONFIDENCE IS
LOW AND WILL NEED TO BE WATCHED CLOSELY. STILL A WET FORECAST FOR
THE WEEK.

.AVIATION...18Z TAF DISCUSSION.

THROWING THE GUIDANCE OUT THE WINDOW...AND BASING THIS FORECAST ON
EXTRAPOLATION OF CURRENT CONDITIONS...AND FORECAST PROFILES.

EVEN LOOKING AT LOWEST LAYER RH FIELDS...MODELS NOT HANDLING
EXTENSIVE LOW CLOUD DECK WELL AT ALL.  CURRENT SAT DOES SHOW SOME
THIN SPOTS IN THE DECK...BUT BELIEVE PREDOMINANT CONDITIONS WILL
REMAIN BKN OR OVC IFR OR LOW MVFR CONDITIONS FOR ALL BUT MGM AND TOI
FOR THE AFTERNOON.  M/VFR CIGS SOUTH WITH VCTS/SHRA WILL EVENTUALLY
YIELD TO LOWER MVFR CIGS ONCE THE FRONT PASSES...BY 20Z AT MGM...BUT
NOT UNTIL LATER THIS EVENING AT TOI.  MODELS ARE HELPFUL THOUGH...IN
INDICATION THAT THE FRONT WILL SLOW DOWN TO A CRAWL AND BECOME QS
OVERNIGHT...WHICH MEANS A VERY PERSISTENT IFR/MVFR FORECAST THROUGH
THE ENTIRE PERIOD...MAINLY FOR CIGS BUT DO EXPECT SOME REDUCTION IN
VIS. IN THE VCNTY OF THE FRONT...ESP AT MGM...POSSIBILITY OF V/LIFR
CONDITIONS EARLY TOMORROW MORNING...BUT WILL ONLY INDICATE VLIFR
CIGS FOR NOW.

NOTICE...KEET TAF WILL HAVE (AMD LTD TO VIS WIND AND WX) AMENDED
TO THE END OF THE FORECAST THROUGH THE END OF THE 2010/2011 WINTER
SEASON. THE CEILOMETER DATA WILL BE GOING THROUGH NUMEROUS TESTS
AND MONITORED FOR ACCURACY.
