NWS Jackson, MS wrote its last area forecast discussion before the first event at Jul 12, 9:45 AM CST, 5 hours 7 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON MS 1045 AM CDT SUN JUL 12 2009 .UPDATE...MADE SOME MINOR CHANGES TO THE FORECAST THIS MORNING. TWEAKED MAX TEMPS FOR TODAY BASED ON LATEST GUIDANCE. MAX TEMPS ACROSS PORTIONS OF THE DELTA WERE LOWERED JUST A LITTLE TO ACCOUNT FOR LINGERING SHOWERS AND CLOUD COVER...WHILE MAX TEMPS ACROSS PORTIONS OF THE EAST WERE RAISED SLIGHTLY TO ACCOUNT FOR MORE RAPID WARMING THAT HAS BEEN OCCURRING THIS MORNING. LOWERED MORNING POPS ACROSS THE DELTA AS SHOWER ACTIVITY HAS MAINLY DISSIPATED. ADDITIONAL SHOWER AND THUNDERSTORM ACTIVITY WILL DEVELOP THIS AFTERNOON WITH GREATEST COVERAGE OVER EASTERN MISSISSIPPI. SOME STORMS COULD BECOME STRONG TO SEVERE DUE TO A MOIST AND UNSTABLE AIRMASS. NO OTHER CHANGES TO THE FORECAST WERE MADE. /27/ && .PREVIOUS DISCUSSION...SHORT TERM...TODAY THROUGH MONDAY NIGHT...THE LATEST GFS/ECMWF/GEFS SOLUTIONS ARE IN GOOD AGREEMENT ON THE HOT SUBTROPICAL RIDGE AXIS CONTINUING TO EXTEND ACROSS THE SRN PLAINS INTO THE LOWER MS VALLEY RIDGE EARLY THIS WEEK. A SERIES OF UPPER LEVEL PERTURBATIONS WILL CONTINUE TO ROTATE SWD AROUND THE EAST SIDE OF THE RIDGE OVER THE NEXT FEW DAYS...WITH THE GREATEST CONVECTIVE COVERAGE EXPECTED FROM NORTH CENTRAL TO EAST CENTRAL MS. PRECIPITABLE WATER AIR OF 2+ INCHES COMBINED WITH LARGE AMOUNTS OF AFTN CAPE WILL SUPPORT REDEVELOPMENT OF TSTM ACTIVITY THIS AFTN. DEEP LAYER SHEAR OF 20-30KTS WILL SUPPORT STORM ORGANIZATION INTO MULTICELL CLUSTERS CAPABLE OF PRODUCING DAMAGING WIND GUSTS AND WILL MENTION THIS IN THE HWO. EXPECT A SIMILAR SET-UP FOR MONDAY-MONDAY NIGHT WITH RIDGE POSITION STILL ABOUT THE SAME AND MORE SHORTWAVE ENERGY IN THE WESTERLIES DROPPING SWD AROUND EAST SIDE OF THE RIDGE...SO SVR WX WILL BE POSSIBLE AGAIN. AS FOR TEMPERATURES...CONVECTIVE DEBRIS ASSOC WITH THE SYSTEM MOVING INTO NRN PORTIONS OF THE AREA THIS MORNING COULD TEMPER HEATING...BUT STILL EXPECT MID/UPPER 90S AFTN HIGHS WILL BE COMMON AGAIN PER MAV GUIDANCE. HEAT STRESS LEVELS ALONG AND WEST OF THE MS RIVER WILL BE NEARING CRITICAL LEVELS AND A HEAT ADVISORY ISSUANCE COULD BE NECESSARY IN THE NEXT COUPLE OF DAYS. /EC/ LONG TERM...TUESDAY THROUGH SUNDAY. THE MODEL SOLUTIONS CAME IN A LITTLE DIFFERENT FOR THE EXTENDED TODAY...SO STUCK WITH GUIDANCE. THE MAV/MEX WAS MUCH COOLER AND POPS WERE A LITTLE HIGHER. USED THE ENSEMBLE VALUES FOR POPS AND TEMPS...WHICH WERE SLIGHTLY WARMER. THE MAV IS WET FOR MUCH OF THE WEEK...NOT COMPLETELY SURE ABOUT RAIN CHANCES OR THE COOLER TEMPERATURES AT THIS POINT. THE GFS CONTINUES TO SHOW THE UPPER RIDGE IN PLACE AND MOST OF THE ACTIVITY STAYING OUT OF THE CWA TO THE EAST IN THE NEAR TERM...BUT MODEL DOES NOT SEEM TO BE HANDLING MCS ALL THAT WELL. A DISTURBANCE DROPS INTO THE AREA MONDAY AND TRACKS TOWARD THE COAST ALONG THE STALLED BOUNDARY EARLY TUESDAY. THE MODELS SHOW THE DISTURBANCE MOVING WEST INTO THE SOUTHEASTERN ZONES. GUIDANCE HAS CHANCE POPS IN THE FORECAST FOR MUCH OF NEXT WEEK...WHERE IT WAS BACKING OFF ON THE RAIN FOR THE EARLY PART OF THE WEEK YESTERDAY. WENT WITH IT AND ADDED RAIN BACK TO THE FORECAST NEARLY EVERYDAY NEXT WEEK. THE 00Z RUN SUGGESTED THE STATIONARY BOUNDARY WOULD GET PUSHED SOUTH WITH THE DISTURBANCE AND MOVE NORTH BACK INTO THE AREA WEDNESDAY...WITH THE BEST POPS ACROSS THE SOUTHEAST. THE WARM FRONT SEEMED TO STALL ALONG I-20 BEFORE BEING PUSHED OUT BY THE NEXT COLD FRONT AND THE BIG UPPER TROUGH EXPECTED TO SWING THROUGH THE AREA AROUND SATURDAY. COOL AND DRY AIR SETTLE OVER THE REGION BY SATURDAY AFTERNOON AND CONTINUES INTO EARLY NEXT WEEK. THE BIGGEST CHANGE WAS TO ADD HIGHER POPS FOR THE REMAINDER OF THE WEEK. DID NOT JUMP ON COOLER TEMPERATURES. ENSEMBLE VALUES WERE IN THE LOWER 90S AND THAT SEEMED GOOD. /07/ && .AVIATION...LIGHT RAIN WAS STILL BEING REPORTED AT GLH FROM A DISSIPATING CLUSTER OF EARLY MORNING STORMS BUT THE RAIN WILL END SOON. ADDITIONAL SHOWER AND THUNDERSTORM ACTIVITY WILL DEVELOP THIS AFTERNOON WITH THE GREATEST COVERAGE OCCURRING OVER EASTERN MISSISSIPPI. AWAY FROM THUNDERSTORMS...VFR CONDITIONS WILL PREVAIL THROUGH MONDAY. THE EXCEPTION WILL BE A BRIEF PERIOD WHERE MVFR RESTRICTIONS FOG/HAZE COULD DEVELOP AGAIN EARLY MONDAY MORNING ESPECIALLY IN LOW-LYING AND RAIN AREAS. /22/ && .PRELIMINARY POINT TEMPS/POPS...
