.DISCUSSION...
/ISSUED 1129 AM CDT THU SEP 11 2014/
SFC LOW PRESSURE IS NORTH OF THE GREAT LAKES WITH A TRAILING COLD
FRONT DOWN ALL THE WAY THROUGH THE OHIO VALLEY AND INTO AR. SHOWERS
AND THUNDERSTORMS HAVE DEVELOPED AHEAD OF THE FRONT IN W TN...AR AND
N MS AND ARE SLOWLY MOVING E. THE UPPER LEVEL WIND FLOW IS NOT
SUPPORTIVE OF QUICK MOVEMENT TODAY AS THEY ARE NEARLY PARALLEL TO
THE FRONT. ISOLATED SHOWERS HAVE DEVELOPED IN PARTS OF THE HUN CWA
THIS MORNING ALONG AN OUTFLOW BOUNDARY OF THE STORMS TO OUR NW AND IN
A WEAK CONVERGENCE AREA ACROSS THE CENTRAL PORTION OF OUR COUNTIES.
INCREASED THE POPS FOR THIS MORNING TO ACCOUNT FOR THIS ISOLATED
DEVELOPMENT AND SFC FEATURES IN PLACE.

STILL EXPECTING SHOWERS AND THUNDERSTORMS TO MOVE INTO THE AREA
LATER THIS AFTERNOON AND TOWARDS THIS EVENING. A LITTLE BIT OF A
DEEPER LAYER OF DRIER AIR IS IN PLACE AS SEEN IN THE REDSTONE
SOUNDING COMPARED TO THE BMX SOUNDING AND IN WATER VAPOR SATELLITE.
THE PWATS ARE HIGH...OVER 1.5 INCHES AND CAPE VALUES ARE OVER 1500
J/KG SO GUSTY WINDS AND HEAVY RAINFALL ARE POSSIBLE WHEN STORMS DO
MOVE INTO THE AREA. INCREASED CLOUD COVER FOR TODAY AS BLOW OFF FROM
THE LARGE CLOUD SHIELD ASSOCIATED WITH THE FRONT IS MOVING IN AND LOW
CLOUDS ARE STILL LINGERING IN NE AL. ALSO ADJUSTED WIND/WIND GUSTS
FOR CURRENT AND EXPECTED TRENDS. LOCATIONS THAT WERE ABLE TO GET
PEEKS OF SUN TODAY HAVE BEEN GUSTING AT TIMES. AS FOR TEMPS...COULD
STILL GET INTO THE UPPER 80S TO 90. THIS COULD BE ADVANTAGEOUS BUT
IF THE CLOUD SHIELD CONTINUES TO HOLD JUST LIKE IT HAS ALL MORNING
OFF TO OUR NW WE COULD CONTINUE TO WARM FAVORABLY. IF IT PICKS UP AND
MOVES INTO THE CWA THEN THESE TEMPS MAY BE A LITTLE HIGH.

.AVIATION...
FOR 18Z TAFS...SHOWERS AND THUNDERSTORMS WILL CONTINUE TO MOVE INTO
THE AREA THIS AFTERNOON AND EVENING AS COLD FRONT APPROACHES THE
TERMINALS. STORMS COULD CAUSE MVFR CONDITIONS WITH LOWER VIS AND
CIGS OTHERWISE VFR CONDITIONS ARE EXPECTED BEFORE SUNSET. MAJORITY
OF THUNDERSTORMS WILL MOVE OUT AFTER 01-03Z WHEN MVFR CIGS AND TRAILING
VCSH WILL BEGIN. MVFR CONDITIONS COULD LAST TILL THE END OF THE TAF
PERIOD IF CLOUD COVER HOLDS.
