AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HUNTSVILLE AL
210 PM CDT SUN MAY 6 2012

.DISCUSSION...
AIR MASS ACROSS MUCH OF THE TN VALLEY REMAINS FAIRLY
CAPPED THIS AFTERNOON...DESPITE MOST OF THE CLOUD COVER CLEARING OR
MOVING SWD INTO CNTRL/SRN AL. A FEW SHOWERS/TSTMS ARE TRYING TO
DEVELOP ACROSS PARTS OF SRN MID TN INVOF A WEAK EMBEDDED VORT MAX.
CU FIELD TRYING TO FORM ACROSS THE ERN PLATEAU MAY ALSO SUGGEST THE
CAP WEAKENING A BIT...AS TEMPS ACROSS MOST OF THE CWA CLIMB INTO THE
80S RANGE. LATEST MODEL RUNS ARE HINTING AT SOME ADDITIONAL ACTIVITY
DEVELOPING LATE THIS AFTERNOON/TONIGHT...AS FURTHER DISTURBANCES
ALOFT TRAVERSE SEWD EMBEDDED WITHIN A WEAK NW FLOW PATTERN. WITH BULK
SHEAR ACROSS THE REGION ALMOST NIL...MOST OF THE CONVECTION WILL
LIKELY TREND MORE PULSE IN NATURE BEFORE TURNING A BIT MORE LINEAR
THIS EVENING/OVERNIGHT...PROVIDED THE MODELS ARE CLOSE WITH
ADDITIONAL MCS LIKE FEATURES DEVELOPING UPSTREAM.

UNSEASONABLY WARM WX CONDITIONS ARE XPCTED TO CONTINUE INTO THE NEW
WORK WEEK...AS AFTERNOON TEMPS ONCE AGAIN FIND THEIR WAY INTO THE
MID/UPPER 80S. THE ONE CAVEAT TO THIS MAY BE CONVECTIVE DEVELOPMENT
INCREASING A BIT ON MON...AS THE FLOW PATTERN BECOMES MORE ZONAL AND
A WEAK COLD FRONT OUT OF THE PLAINS STATES TRANSLATES EWD INTO THE
MIDWEST/LOWER MS VALLEY REGIONS. STRONG EMBEDDED/UPPER SHEAR AXIS
LOOKS TO ACCOMPANY THE SFC FRONT...AS IT PROGRESSES EWD INTO THE
AFTERNOON/EVENING PERIOD MON. WITH THE THERMO PROFILE ACROSS THE
REGION XPCTED TO BE QUITE IMPRESSIVE...WITH ABUNDANT CAPE/STEEP
LAPSE RATES IN PLACE...SOME STRONG TO LOCALLY SEVERE TSTMS ARE
POSSIBLE LATE MON/INTO TUE ALONG/WELL AHEAD OF THE APPROACHING
BOUNDARY. BRIEF DAMAGING WIND GUSTS AND LARGE HAIL LOOK TO BE THE
PRIMARY WX THREATS WITH THE STRONGER STORMS...TO GO ALONG WITH
LOCALLY HEAVY RAINFALL AND FREQUENT LIGHTNING.

THE MODELS ARE IN GENERALLY GOOD AGREEMENT WITH THE COLD FRONT
MOVING INTO THE TN VALLEY ON TUE...WITH ADDITIONAL SHOWERS/TSTMS
DEVELOPING. EXTENSIVE CLOUD COVER THOUGH ACCOMPANYING THE FRONT MAY
INHIBIT MUCH IN THE WAY OF FURTHER AIR MASS DESTABILIZATION...TO GO
ALONG WITH A WEAKENING LOW LEVEL CONVERGENT PATTERN. THIS CERTAINLY
DOESN'T RULE OUT THE POTENTIAL FOR ADDITIONAL STRONG/LOCALLY SEVERE
TSTMS TUE...ALTHOUGH THE PROB IS LOWER COMPARED TO LATE MON AT THIS
POINT. THE FRONT IS THEN XPCTED TO EXIT THE AREA TO THE E TUE NIGHT
INTO WED MORNING...WITH PERHAPS A BIT MORE COOLER/DRIER AIR...OR
MORE SEASONAL LIKE CONDITIONS IN TOW AS A STRONG AREA OF HIGH
PRESSURE BUILDS EWD ACROSS THE MIDWEST/OH VALLEY REGIONS.
