Area forecast discussion, May 6, 3:33 PM CDT, 5 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON MS 333 PM CDT SUN MAY 6 2012 .DISCUSSION...THE MAIN FOCUS IN THE SHORT TERM CONTINUES TO BE THE DAILY CONVECTIVE POTENTIAL AS THE REGION REMAINS A SOMEWHAT ACTIVE PATTERN THANKS TO MULTIPLE DISTURBANCES PROGRESSING GENERALLY E/SE AS THE MEAN PATTERN BREAKS DOWN. EACH PERIOD/DAY WILL OFFER SEPARATE CHALLENGES ON FORECAST CONVECTIVE SPECIFICS DUE TO THE MESOSCALE NATURE OF WHAT WILL TRULY DRIVE THE STRONGEST ACTIVITY. TODAY IS A GREAT EXAMPLE...THE UPPER WAVE WAS WEAKER TODAY...BUT THE PRESENCE OF THE OUTFLOW BOUNDARY AIDED IN BETTER LOW LEVEL CONVERGENCE AND A FEW STORMS WERE ABLE TO REALIZE THE INSTABILITY. FOR THE REST OF THE AFTERNOON/EARLY EVE...LOOK FOR THE CONVECTIVE FOCUS TO BE ACROSS THE I-59 CORRIDOR AS THE BOUNDARY MOVING ACROSS SOUTH AL SLIPS MORE WESTWARD AND HELPS DEVELOPMENT GET GOING ACROSS OUR SE CWA. CONDITIONS ARE NOT QUIET AS FAVORABLE OVER OUR SE (COMPARED TO THE NE)...BUT ENOUGH INGREDIENTS EXIST FOR SOME STRONG/SVR STORMS. THE MAIN RISK WILL BE QUARTER-GOLFBALL SIZED HAIL AND DMG WINDS. POPS AND WX GRIDS WERE ADJ FROM GUID TO ACCOUNT FOR THIS. ADDITIONAL ADJ UPWARD MAY BE NEED AS ACTIVITY CONTINUES TO EVOLVE AND THIS WILL BE MONITORED. MOST OF THE NIGHT PERIOD WILL BE QUIET AFTER THE SE ACTIVITY WANES. LATE IN THE TONIGHT PERIOD...FOCUS LOOKS TO SHIFT TO OUR NW WHERE A MORE SUBSTANTIAL STORM COMPLEX MAY GET GOING. THERE IS SOME LOW CHANCE THIS WILL EVOLVE AND DIVE INTO THE NW CWA...AND THUS COVERED THAT AREA WITH SOME SLIGHT CHC POPS. ON MON...QUESTION MARKS EXIST ON JUST WHERE ANY BOUNDARY EXISTS FROM MORNING CONVECTION AND HOW WILL THAT INTERACT WITH INCREASING INSTABILITY FOR THE AFTERNOON. THERE IS NOT ANY REAL SOLID CONSENSUS ON WHAT WILL HAPPEN...BUT MOST MODELS OFFER A DECENT SHOT AT SEEING STORMS AT SOME POINT MON INTO MON EVE. THERE WILL LIKELY BE SOME LULL PERIOD MON NGT/TUE...BEFORE MORE ACTIVITY DEVELOPS AS THE MAIN SFC COOL FRONT NEARS AND MORE OF THE LONG WAVE UPPER TROUGH GETS INTO THE REGION. AGAIN...DECENT PRECIP CHANCES WILL EXIST TUE/TUE NGT TO ACCOUNT FOR THIS. OVERALL...UNSTABLE CONDITIONS WILL EXIST MON-TUE WITH FAIRLY STEEP LAPSE RATES IN PLACE. STRONG/SVR STORMS WILL BE POSSIBLE DURING THIS TIME WITH HAIL/DMG WINDS THE MAIN RISK. THE OVERALL RISK WILL HIGHLY DEPEND ON PREV DAYS CONVECTION AND WHATEVER IS ONGOING IN THE REGION. MESOSCALE INFLUENCES WILL BE CRITICAL TO DETERMINE WHAT POTENTIAL WILL EXIST AND RIGHT NOW...THERE IS NO GUID THAT OFFERS ANYTHING CLOSE TO INCREASE CONFIDENCE ON SVR STORM SPECIFICS. WILL BE INTERESTING TO SEE HOW THINGS EVOLVE THE NEXT FEW DAYS BEFORE MUCH COOLER CONDITIONS ARRIVE FOR THE SECOND HALF OF THE WEEK. /CME/ && .AVIATION...ALL SITES ARE VFR THIS AFTERNOON AND THIS WILL CONTINUE THROUGH THE LATE EVENING HOURS. THE ONLY EXCEPTION WILL BE AN ISOLATED THUNDERSTORM POSSIBLE AT JAN/MEI/HBG THIS AFTERNOON AND THIS MAY BRING BRIEF MVFR/IFR CONDITIONS. WINDS THIS AFTERNOON WILL AGAIN BE SOUTHERLY BETWEEN 5-10 KNOTS...THEN DECREASING TO AROUND 5 KNOTS OVERNIGHT. PATCHY AREAS OF FOG/STRATUS ARE POSSIBLE ONCE AGAIN SUNDAY MORNING...ESPECIALLY FOR MEI/HBG. /15/ && .PRELIMINARY POINT TEMPS/POPS...
