NWS Jackson, MS wrote its last area forecast discussion before the first event at Sep 5, 2:15 PM CST, 1 hour 45 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON MS 315 PM CDT FRI SEP 5 2014 .SHORT TERM...(TONIGHT THROUGH SUNDAY NIGHT) WATER VAPOR IMAGERY WAS INDICATING A MID LEVEL SHORTWAVE OVER THE ARKLAMISS. WARM ADVECTION...2 INCH PLUS PWATS AND ASCENT OVER THE REGION WITH MIDLEVEL WET BULB ZERO LEVELS WAS ALLOWING WARM RAIN PROCESSES IN SCATTERED SHOWERS AND THUNDERSTORMS OVER THE REGION. FOR THIS AFTERNOON INTO TONIGHT...EXPECT THE CONVECTION TO CONTINUE WITH SOME POTENTIAL OF SOME LOCALLY HEAVY DOWNPOURS IN SLOW MOVING STORMS WITH SOME ASSOCIATED OUTFLOW BOUNDARIES. EXPECT THE ACTIVITY TO WANE BY 00-03Z WITH SOME ISOLATED COVERAGE ACROSS THE AREA ENDING BY 04Z. THIS WAS VERIFIED BY NATIONAL AND LOCAL WRF MODELS. THERE IS ALSO SOME POTENTIAL FOR SOME PATCHY FOG IN THE EAST AND SOUTHEAST. WILL LET THE EVENING SHIFT TAKE ANOTHER LOOK AT THAT PROSPECT. WILL LEAVE IT OUT OF THE GRIDS FOR NOW. EXPECT THE SHORT WAVE TO MOVE WEST OF THE REGION BY EARLY SATURDAY. FOR SATURDAY INTO SUNDAY NIGHT...A WEAK FRONT WILL MOVE INTO THE REGION ON SATURDAY NIGHT INTO SUNDAY. ONCE AGAIN PWATS AROUND 2 INCHES WITH GOOD MOISTURE CONVERGENCE AROUND THE FRONTAL BOUNDARY WILL PROVIDE DECENT FOCUS FOR SHOWERS AND THUNDERSTORMS. SOME OF THE STORMS MAY BRING SOME LOCALLY HEAVY RAINFALL WITH LIGHT CORFIDI VECTORS ON SATURDAY. DO NOT SEE ANY ORGANIZED UPDRAFTS FOR ANY REAL SEVERE POTENTIAL FOR NOW. SO WILL KEEP THE HWO CLEAR. OUR CHANCES OF RAIN WILL DECREASE FROM THE NORTH ON SUNDAY INTO SUNDAY NIGHT AS WE GET SOME MIDLEVEL DRYING BEHIND THE WEAK FRONT. WE MAY GET SOME MID 60S DEWPOINTS IN THE NORTHWEST DELTA REGION ON SUNDAY. AS FAR AS TEMPS ARE CONCERN WENT CLOSE TO A MET AND MAV BLEND FOR NIGHTLY MILDER LOWS. FOR DAILY HIGHS WENT CLOSE TO A COOLER MET GUIDANCE FOR SATURDAY AND SUNDAY ESP FOR SATURDAY WITH MORE RAIN POTENTIAL. AS FAR AS POPS ARE CONCERN WENT GENERALLY CLOSE TO GMOS GUIDANCE. .LONG TERM...MONDAY THROUGH FRIDAY...THIS PERIOD WILL FEATURE ONE COLD FRONT ACROSS THE CWA. THE STRONGER COLD FRONT WILL ARRIVE THURSDAY. ON MONDAY OUR CWA WILL BE ON THE EASTERN PERIPHERY OF A FLATTEN MEAN RIDGE WITH A 591 DAM HIGH OVER THE SOUTHERN PLAINS WITH A >1020MB SURFACE HIGH CENTERED OVER THE NEW ENGLAND STATES. MODELS ARE IN GOOD AGREEMENT THAT THE COLD FRONT WILL PUSH SOUTH OF OUR SOUTHERN ZONES AND THEN STALL OVER THE GULF COAST BY MONDAY. THE RATHER FLAT MID LEVEL RIDGE WILL REMAIN OVER OUR REGION THROUGH WEDNESDAY. A SURFACE LOW WILL DEVELOP OVER THE CENTRAL PLAINS TUESDAY AND A WEAK SURFACE RIDGE WILL BEGIN NOSING WEST OVER THE NORTHERN GULF. THIS WILL RESULT IN RETURN FLOW TUESDAY AND WEDNESDAY WORKING TO INCREASE DEEP MOISTURE BACK OVER OUR WHOLE CWA. SLIGHTLY WARMER THAN NORMAL TEMPERATURES ARE EXPECTED TUESDAY AND WEDNESDAY. THE WARMER TEMPERATURES WILL COMBINE WITH THE MOISTURE INCREASE FOR DIURNAL ISOLATED TO SCATTERED COVERAGE OF STORMS EACH DAY. BY THURSDAY THE SURFACE LOW OVER THE CENTRAL PLAINS WILL HAVE MOVED NORTHEAST OVER THE NEW ENGLAND STATES IN RESPONSE TO A SHORTWAVE TROUGH DROPPING OVER THE CENTRAL CONUS. THIS SHORTWAVE WILL HELP SUPPORT A STRONGER COLD FRONT THAT WILL MOVE INTO OUR CWA THURSDAY AND BRING THE NEXT BEST CHANCE FOR WIDESPREAD RAIN. THE COLD FRONT WILL SHIFT SOUTH OF OUR CWA FRIDAY AND THIS WILL BRING COOLER AND DRIER WEATHER BY FRIDAY NIGHT. /22/ && .AVIATION...FOCUS FOR THE REMAINDER OF AFTERNOON WILL BE ON THE CONVECTION. IT WAS TOUGH TO PUT TIGHTER TIMING ON THE ACTIVITY EARLIER...JUST DECIDED TO USE VC WORDING AND UPDATE AS NEEDED. THAT STILL SEEMS TO FIT THE SITUATION. EXPECT SOME RESTRICTIONS WITH ANY SITE IMPACTED BY STORMS WITH A RETURN TO VFR AFTER ANY HAS PASSED BY. A GOOD PART OF THE EVENING WILL BE VFR...BUT DUE TO LIKELY LINGERING WET GROUND CONDITIONS...MVFR VIS ARE ANTICIPATED AFTER 08-10Z WITH A TREND TO VFR BY 14Z. LOOK FOR INCREASING SHRA/TSRA CHANCES AGAIN FOR SAT AFTERNOON. /CME/ && .PRELIMINARY POINT TEMPS/POPS...
