AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON MS 318 PM CDT THU JUL 18 2013 .SHORT TERM... SCATTERED STRONG STORMS CONTINUE TO DEVELOP FROM THE JACKSON METRO AREA WEST AND NORTHWEST IN ASSOCIATION WITH VORTICITY MAXIMUM MOVING WSW ACROSS AREA. RELATIVELY STEEP LOW TO MID LEVEL LAPSE RATES AND HIGH LOW LEVEL MOISTURE WILL CONTINUE TO SUPPORT GUSTY WINDS... FREQUENT LIGHTNING...AND MAYBE A LITTLE HAIL WITH THESE STORMS AS THEY BUILD SW INTO HIGH INSTABILITY AIRMASS. A FEW SEVERE STORMS MAY STILL OCCUR...ESPECIALLY NEAR MERGERS OR WHERE BOUNDARIES INTERACT CAUSING LOCAL UPDRAFT ENHANCEMENT. SUBSIDENCE IN WAKE OF VORTMAX HAS KEPT CONVECTION AT BAY FARTHER TO THE EAST ACROSS EASTERN MS SO FAR. HOWEVER...SATELLITE IMAGERY IS SHOWING SOME ENHANCED CU DEVELOPING ACROSS PARTS OF EAST CENTRAL MS...AND LAPS INDICATES FAIRLY RAPID DESTABILIZATION HAS OCCURRED ALONG AN AXIS FROM GLH TO QUITMAN...WITH SBLI DOWN AROUND -7. HENCE WILL KEEP CHANCE POPS IN FOR THE EVENING ALONG WITH A MENTION OF A STRONG STORM IN THIS AREA. DO NOT EXPECT THE COVERAGE OR INTENSITY OF CONVECTION LATER TONIGHT THAT WE SAW MOVE W FROM AL LAST NIGHT...BUT GIVEN PROXIMITY OF UPPER LOW CENTER TO OUR SW WILL KEEP SLGT CHANCE POPS IN ALL NIGHT. MODELS SHOW VERY LITTLE CHANGE TO OVERALL WEATHER PATTERN NEXT COUPLE OF DAYS AS UPPER LOW TAKES UP RESIDENCE OVER SOUTH CENTRAL LA...AND SPOKES OF ENERGY ROTATE AROUND IT AND INCITE SHRA/TSRA DEVELOPMENT. GREATEST POPS WILL BE DURING THE AFTERNOON/EVENING BUT WILL CERTAINLY NOT BE ABLE TO RULE OUT CONVECTION AT PRETTY MUCH ANY TIME. AS HAS BEEN RECENT TREND...GFS POPS SEEM TO LOW AND WERE RAISED 10-20 PCT MOST AREAS/PERIODS THROUGH SAT. LAPSE RATES DO NOT LOOK QUITE AS FAVORABLE FOR INTENSE CONVECTION NEXT COUPLE OF DAYS GIVEN A DEG OR TWO OF WARMING IN MID LEVELS...BUT WILL NEED TO ANALYZE OBSERVATIONAL DATA FOR ENHANCED AREAS OF MICROBURST POTENTIAL IN NEAR TERM. .LONG TERM... STATUS QUO PRETTY MUCH HOLDS INTO EARLY PART OF NEXT WEEK AS WEAKNESS/UPPER LOW MEANDERS AROUND AND KEEPS SCATTERED CONVECTION AROUND. 12Z MEDIUM RANGE MODELS IMPLY SOME POTENTIAL FOR A BIT OF A CHANGE IN SETUP TOWARD MIDDLE OF NEXT WEEK AS THERMAL RIDGE DROPS INTO AREA AND UPPER RIDGE BUILDS TO OUR W. IF THIS WERE TO PAN OUT...COULD SEE SOME TRULY HOT SUMMER WEATHER DEVELOP ACROSS THE REGION FOR REALLY THE FIRST TIME THIS SEASON. JUST SOMETHING TO KEEP AN EYE ON AT THIS POINT. && .AVIATION... TSRA IS ONGOING ACROSS THE MS DELTA REGION AND CENTRAL MS AND WILL MOVE INTO WRN AREAS THROUGH THE MID TO LATE AFTN HOURS. KGLH WILL BE IMPACTED BY TSRA NEXT HOUR WITH LIFR CONDS LIKELY AS VIS DROPS IN HEAVY DOWNPOURS. LIFR CONDS WILL IMPROVE BACK TO VFR BY 21Z. THE -RA NEAR KGWO WILL CONTINUE TO LIGHTEN AND ABATE BY 1930Z. THERE IS STILL SOME OUTSIDE CHANGE OF VCTS NEAR KJAN/KHKS THIS AFTN AND WILL CONTINUE WORDING IN TAFS. STORMS WILL DIMINISH THROUGH THE EARLY TO MID EVENING IN THE WEST. FOG POTENTIAL HAS INCREASED WITH SEVERAL SITES RECEIVED GOOD RAIN AMOUNTS TODAY. MVFR FOG/BR AT MOST LOCATIONS 08-14Z WITH IMPROVEMENT TO VFR THEREAFTER. ANOTHER ROUND OF SHOWERS AND STORMS IS LIKELY TOMORROW AND WILL PLACE VCTS IN TAFS FOR THE AFTN PERIOD. /ALLEN/ && .PRELIMINARY POINT TEMPS/POPS...
