AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE JACKSON MS
312 PM CDT MON JUN 13 2011

.UPDATE...DID A QUICK UPDATE TO ADD SEVERE THUNDERSTORM WATCH 473
UNTIL 9PM/02Z FOR JUST ABOUT THE ENTIRE CWA. MCS ABOUT TO MOVE INTO THE
NORTHERN PARTS OF THE CWA. THIS SYSTEM HAS HAD A HISTORY OF DAMAGING
WINDS WITH A REPORTED 75MPH WIND GUST AT MEMPHIS EARLIER. COMPLEX IS
PROGGED TO MOVE INTO THE JACKSON METRO AROUND 6PM/23Z. /28/

&&

.PREV DISCUSSION... /ISSUED 1223 PM CDT MON JUN 13 2011/

UPDATE...DID A QUICK UPDATE TO INCREASE POPS FURTHER IN THE EAST.
LOOKS LIKE THE MCS UPSTREAM IS LIKELY TO HOLD TOGETHER AS IT BARRELS
SOUTH/SOUTHEAST AROUND THE RIDGE. SLIGHT RISK HAS NOW BEEN EXTENDED ALL THE WAY
TO THE MS COAST WITH THE PRIMARY CONCERN BEING WIND AND HAIL. EXPECT
THE BOUNDARY LAYER TO BE SUFFICIENTLY DESTABILIZED WITH TEMPS EXPECTED
TO BE IN THE MID TO UPPER 90S AND DEWPOINTS IN THE UPPER 60S AND
LOWER 70S ACROSS THE AREA. INCREASED POPS TO NUMEROUS CATEGORY IN THE
GOLDEN TRIANGLE AREA AND TAPERED LESS THE FURTHER SOUTH AND
ESPECIALLY WEST YOU GO. AGAIN FEEL THE WEST IS THE LEAST LIKELY TO
SEE SIGNIFICANT CONVECTION GIVEN INFLUENCE OF THE RIDGE. UPDATED
PRODUCTS OUT. /28/

PREV DISCUSSION... /ISSUED 1059 AM CDT MON JUN 13 2011/

UPDATE...INTERESTING FORECAST FOR TODAY AS NORTHERN PORTIONS OF
THE CWA HAVE BEEN INCLUDED IN THE SPC DAY 1 SLIGHT RISK. THIS COMES
AS AN MCS ONGOING ACROSS MISSOURI AND  INTO NORTHERN ARKANSAS LOOKS
TO SLIDE DOWN THE EASTERN PERIPHERY OF THE BUILDING SUBTROPICAL
RIDGE. IN FACT PORTIONS OF NORTH MISSISSIPPI...JUST TO THE NORTH OF
MY CWA...HAVE BEEN INCLUDED IN A SVR THUNDERSTORM WATCH. IT IS A BIT
UNCLEAR AS TO IF THIS MCS WILL STAY TOGETHER OR BE DISSIPATING BY
THE TIME IT REACHES THE CWA. MUCH OF THE MODEL GUIDANCE AS WELL AS
LOCAL AND NATIONAL HI-RES WRF SHOW THAT THE MCS SHOULD BE MOSTLY
DISSIPATING BUT OUTFLOWS FROM THIS WILL LIKELY INTERACT WITH THE
MOIST AND UNSTABLE AIRMASS OVER THE REGION TO BRING SCATTERED STORMS
TO THE EASTERN PORTION OF THE CWA(AND THIS IS WELL INDICATED BY
LOCAL WRF RUNS). GIVEN GOOD LAPSE RATES AND DECENT DCAPE...BETTER
WIND SHEAR THAN PREVIOUS DAYS AND ABUNDANT MOISTURE...THERE WILL BE
THE POTENTIAL FOR STRONG TO SVR STORMS WITH THIS COMPLEX OR STORMS
GENERATED FROM THE OUTFLOW. THE MAIN CONCERNS WITH THIS WOULD BE
FROM HAIL AND WIND....THOUGH WITH POTENTIAL SLOW MOVEMENT OF STORMS
THERE COULD ALSO BE LOCALLY HEAVY RAINFALL.  FURTHER TO THE
WEST...THE 590DM RIDGE WILL BE STRONGEST GENERALLY ALONG AND WEST OF
THE MISSISSIPPI RIVER. THIS AREA WILL LIKELY NOT SEE AS MUCH
CONVECTION BUT THERE STILL COULD BE AN ISOLATED STORM. KEPT POPS
AROUND 10% HERE WHILE UPPING THE EAST TO AROUND 30%. LOOKS LIKE
STORMS COULD BEGIN AS EARLY AS 18Z BUT OTHER MODELS WAIT UNTIL
CLOSER TO 20Z AND LAST THROUGH 02Z.

OTHER WEATHER ELEMENTS...TEMPERATURES TODAY WILL BE WARM AGAIN WITH
THE BUILDING HEIGHTS AND WARMER LOW LEVEL TEMPS. HIGHS COULD BE TRICKY
TODAY DEPENDING ON HOW QUICKLY CONVECTION DEVELOPS. WITH READINGS
THIS MORNING RUNNING IN THE MID TO UPPER 80S...HIGHS IN THE MID TO
UPPER 90S SEEM LIKELY. ANY EARLY CLOUD COVER OR CONVECTION COULD
CERTAINLY HAMPER THESE HIGHS. MADE SOME ADJUSTMENTS TO CLOUD COVER
AND HOURLY GRIDS BUT OTHERWISE UPDATED PRODUCTS ON THE WAY OUT. /28/

&&

.AVIATION...

GWO AND MEI REPORTED MVFR CONDITIONS EARLY THIS MORNING
BUT THE FOG HAS DISSIPATED...ALTHOUGH SOME HAZE WAS HANGING AROUND
GWO AT 14Z. VFR CONDITIONS WILL PREVAIL THROUGH THIS EVENING AT MOST
LOCATIONS BUT A COMPLEX OF THUNDERSTORMS ORGANIZING OVER THE MID
MISSISSIPPI VALLEY THIS MORNING MAY COME DOWN INTO THE NORTHERN
PORTIONS OF OUR AREA THIS AFTERNOON AND INTO THE EVENING BEFORE
DISSIPATING. ELSE...ISOLATED SHOWERS AND THUNDERSTORMS ARE EXPECTED
TO DEVELOP AGAIN BY MID AFTERNOON MAINLY ALONG AND EAST OF I-55 AND
CONTINUE INTO THIS EVENING. MVFR CONDITIONS DUE TO PATCHY GROUND FOG
DEVELOPMENT WILL MAKE A RETURN AGAIN TUESDAY MORNING...ESPECIALLY IN
THE NORTH WHERE HEAVY RAINS FALL WITH THE POSSIBLE MCS. /22/
