NWS Jackson, MS wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 2, 2:00 PM CDT, 2 hours 49 minutes earlier.
Area forecast discussion, Jul 2, 2:00 PM CDT, 2 hours 49 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON MS 200 PM CDT SAT JUL 2 2005 .SHORT TERM... LATEST SATELLITE IMAGERY WAS SHOWING A SHORT WAVE THAT HAD TRIGGERED AN MCS WITH A GOOD COOL POOL OVER EAST TEXAS AND WESTERN LOUISIANA. ON THE SURFACE AN ILL-DEFINED BOUNDARY CONTINUE TO BE DRAPED ACROSS THE REGION. THE 850 THETA RIDGE AXIS AND MID LEVEL WINDS SHOULD PUSH THE COMPLEX SOUTHWEST OF THE REGION...POSSIBLE CAUSING SOME EVENING CONVECTION IN THE SOUTH...WHERE BEST EVENING LOW POPS WILL BE FORECASTED. THE GFS SEEMED TO DO THE BEST JOB IN TRACKING THE COMPLEX SOUTHWEST OF THE REGION. MID LEVEL WIND FLOW OF AROUND 20KTS WILL BE SUPPORTIVE OF MULTICELL LATE AFTERNOON AND EARLY EVENING THUNDERSTORMS. STILL EXPECT STEEP LOW LEVEL LAPSE RATES TO DEVELOP THAT WOULD BE SUPPORTIVE OF DAMAGING DOWNBURST WINDS IN STRONGER STORMS FOR LATE THIS AFTERNOON AND INTO THE EARLY EVENING. BELIEVE THE POSSIBILITY FOR GREATER SHOWER/THUNDERSTORM COVERAGE MAY OCCUR OVER EAST LOUISIANA AND SOUTH MISSISSIPPI WHERE WEAK FORCING FROM THE TROUGH SHOULD PROVIDE ENHANCEMENT. ALSO SOME COASTAL CONVECTION SHOULD PROVIDE SOME OUTFLOW BOUNDARIES IN ORDER TO TRIGGER SOME CONVECTION IN OUR SOUTHERN COUNTIES FOR LATE THIS AFTERNOON AND EARLY THIS EVENING. CONVECTION SHOULD DIMINISH QUICKLY AFTER SUNSET...TO BE FOLLOWED BY A QUIET REMAINDER OF THE NIGHT. SUNDAY SHOULD NOT BE A WHOLE LOT DIFFERENT THAN TODAY IN TERMS OF THUNDERSTORM LOCATION AND COVERAGE. THE WEAKENING BOUNDARY IS NOT EXPECTED TO BE AS ACTIVE AND HAVE PLACED LOWER POPS ACCORDINGLY. FORECAST HIGH TEMPS SUNDAY ARE TRICKY WITH MAV/MET GUIDANCE SUGGESTING UPPER 90S MAY BE MET IN THE DELTA REGION...WITH MID 90S ELSEWHERE. WILL KEEP LOW TO MID 90S AREA WIDE...AS LOW LEVEL TEMPS DO NOT FAVOR UPPER 90S. /#17/ LONGTERM... SUNDAY NIGHT THROUGH MONDAY NIGHT...WARM/HUMID CONDITIONS TYPICAL OF JULY TO PERSIST. THE SFC FRONT THAT HAS AFFECTED THE AREA OVER THE PAST FEW DAYS WILL WASH OUT...HOWEVER A WEAK SHEAR AXIS ALOFT WILL LINGER. THIS WILL MAINTAIN SLGT CHC/LOW END CHC POPS ACROSS THE AREA DURING THE AFTERNOON AND EVENING HOURS. TUESDAY THROUGH SATURDAY...OPS MED RANGE GUIDANCE AND ENSEMBLES CONTINUE TO BE IN GENERAL AGREEMENT WITH THE EVOLUTION OF THE UPPER PATTERN THROUGH NEXT WEEK. WEAK RIDGING ALOFT LOOKS TO BUILD IN OVER THE INTERMOUNTAIN WEST WHILE THE EASTERN CONUS WILL BE INFLUENCED BY WEAK TROUGHING. WILL BE CLOSELY MONITORING A LARGE AREA OF MOISTURE/DISTURBED WX OVER THE WESTERN CARRIBEAN. TROPICAL CONSEQUENCES ARE UNCERTAIN AT THIS POINT...VIEW THE LATEST TWOAT FROM THE NHC FOR MORE INFO...HOWEVER THIS FEATURE IS EXPECTED TO MOVE INTO THE GULF OVER THE NEXT FEW DAYS AND SPREAD A PLUME OF HIGH PW AIR (2-2.5 INCHES) INTO THE REGION AROUND MIDWEEK. CURRENT POP FORECAST HANDLES THE SITUATION QUITE WELL...WITH VALUES IN THE HIGH CHC RANGE TUE THROUGH THU. BULK OF THE AFOREMENTIONED MOISTURE PLUME SHOULD EXIT TO OUR EAST BY FRIDAY...HOWEVER THE AREA WILL STILL BE INFLUENCED BY TYPICAL SUMMERTIME AFTERNOON/EVENING CONVECTION AND HAVE STOOD PAT WITH CLIMO POPS. TEMP WISE...A BIT OF A TRICKY FORECAST IN THIS REGARD. AM EXPECTING FAIR AMOUNT OF CLOUDS AND SHRA/TSRA ACTIVITY THU THROUGH THUR. THUS HAVE KEPT HIGHS BELOW AVG IN MY SOUTH AND CLOSER TO AVG ELSEWHERE. CERTAINLY COULD BE COOLER IF CONVECTION OVERSPREADS THE REGION EARLY IN THE DAY. BY WEEKS END...TEMPS SHOULD RETURN TO VALUES TYPICAL OF JULY. /GAGAN/ && .AVIATION...WITH CURRENT INSTABILITY TRENDS EXPECT VCTS AT KMEI AND KHBG...BEFORE ENDING AFTER SUNSET. MOST STATIONS SHOULD DROP DOWN IN THE MVFR RANGE ALONG...OR SHORTLY AFTER...MIDNIGHT. TEMPORARY IFR REDUCTIONS WILL BE POSSIBLE AS WELL TOWARD DAWN ALTHOUGH IM ONLY CONFIDENT AT PINPOINTING KGWO AND KGLH FOR AT THIS TIME. OTHERWISE...EXPECT VCTS SHOWERS AND STORMS COMING IN ON MAINLY SUNDAY AFTERNOON FOR MAINLY KMEI AND KHBG WITH A LOW CHANCE AT KJAN. /#17/ && .JAN WATCHES/WARNINGS/ADVISORIES... MS...NONE. LA...NONE.
