AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE HUNTSVILLE AL
231 PM CDT MON MAR 18 2013

.DISCUSSION...
STRONG/SVR CONVECTION IS IMPACTING MUCH OF THE CNTRL/WRN HALF OF THE
AREA THIS AFTERNOON...ALONG A PRE-FRONTAL AXIS PUSHING EWD INTO MID
TN LEADING INTO EXTREME NE MS. THIS ACTIVITY SHOULD GRADUALLY MAKES
ITS WAY EWD THROUGH THE REMAINDER OF THE AFTERNOON PERIOD...WITH
DAMAGING WINDS AND LARGE HAIL THE PRIMARY THREATS. THERE IS A LOW
END TORNADO THREAT GIVEN THE STRENGTH AND SOMEWHAT VEERING PROFILE
OF THE LOW LEVEL WIND FIELD...ALTHOUGH THE GREATER PROB EXISTS MORE
INTO CNTRL/SRN AL WHERE BETTER LOW LEVEL INSTABILITY IS IN PLACE. A
SVR TSTM WATCH/SVA 52 IS IN PLACE THROUGH 9 PM FOR THE ENTIRE AREA.
HOWEVER...AS THE BULK OF THE STRONGER CONVECTION CONTINUES TO MOVE
EWD INTO THE LATE AFTERNOON HRS...THE SVR WX THREAT SHOULD BEGIN TO
DIMINISH FROM W TO E AND LIKEWISE THE WATCH WILL MORE THAN LIKELY BE
CANCELLED STARTING WITH THE WRN COUNTIES. THE COLD FRONT ITSELF WILL
BEGIN TO MOVE EWD ACROSS THE AREA EARLY THIS EVENING...WITH PRECIP
TAPERING OFF WITH THE FRONTAL PASSAGE.

QUIET AND MORE SEASONAL LIKE WX IS THEN XPCTED STARTING TUE...AS A
STRONG AREA OF HIGH PRESSURE OUT OF THE NRN/MID PLAINS BUILDS INTO
THE SE REGION. THE SFC HIGH ACTUALLY LOOKS TO BECOME REINFORCED
ACROSS THE MIDWEST REGION GOING PAST MID WEEK AS THE FLOW PATTERN
TURNS SOMEWHAT TOWARD THE NW. THIS LOOKS TO RESULT IN YET ANOTHER
UNSEASONABLY COLD NIGHT WED...AS OVERNIGHT LOWS FALL MORE INTO THE
MID/UPPER 20S. CONDITIONS/TEMPS SHOULD THEN BEGIN TO REBOUND BY THU
AS THE SFC HIGH GRADUALLY MAKES ITS WAY EWD ACROSS THE REGION.

UNFORTUNATELY THE FORECAST BECOMES SOMEWHAT MURKY HEADING TOWARD THE
END OF THE WORK WEEK. LATEST GLOBAL MODEL SUITES ARE HINTING AT THE
OVERALL PATTERN BECOMING QUITE ACTIVE LATE THU AND INTO FRI...AS THE
SRN STREAM INTERACTS WITH DEVELOPING ENERGY ALONG THE SRN END OF A
SHARP AMPLIFYING TROUGH PATTERN ACROSS THE PLAINS STATES. GENERAL
CONSENSUS THOUGH IS NOT THAT GOOD REGARDING SPECIFIC FEATURES AND
TIMING WITH THE EVOLVING WX PATTERN...OTHER THAN PRECIP/SHOWERS
DEVELOPING INVOF MULTIPLE SFC WAVES ACROSS THE LOWER SE. HOPEFULLY
THE RUN TO RUN CONTINUITY AMONG THE VARIOUS MODELS IMPROVES AS MID
WEEK APPROACHES.
