NWS Jackson, MS wrote its last area forecast discussion before the first event at Jun 15, 2:22 PM CST, 4 hours 11 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON MS 322 PM CDT FRI JUN 15 2012 .SHORT TERM...TONIGHT THROUGH SUNDAY NIGHT...THE THUNDERSTORM ACTIVITY SHOULD DISSIPATE BY SUNSET OR SOON THERE AFTER THIS EVENING ..LEAVING MOSTLY CLEAR SKIES FOR THE AREA OVERNIGHT. UPPER AND SURFACE HIGH PRESSURE RIDGING WILL STRENGTHEN ON SATURDAY...BUT PWATS WILL STILL REMAIN AROUND 1.5-1.6 INCHES SATURDAY AFTERNOON MAINLY FOR AREAS ALONG AND WEST OF I-55. THE GFS IS NOT INDICATION THE DEVELOPMENT OF ANY CONVECTION ON SATURDAY...BUT AFTER LOOKING AT THE LOCAL AND NCEP WRF HI-RES MODELS...EXPECT THERE TO BE AT LEAST ISOLATED DEVELOPMENT ALONG AND WEST OF I-55 IN THE AFTERNOON BEFORE MUCH DRIER AIR BUILDS IN DURING THE LATE AFTERNOON AND EVENING. EXPECT ANY STORMS THAT DO DEVELOP TO REMAIN BELOW SEVERE LIMITS...BUT AN ISOLATED STRONG STORM CANNOT BE RULED OUT. DRIER AIR WILL CONTINUE TO ROTATE AROUND THE RIDGE ON SUNDAY WITH PWATS FALLING TO AROUND AN INCH OVER MOST OF THE AREA...EXCEPT FOR THE SOUTH WERE PWATS WILL REMAIN AROUND 1.5 INCHES. EXPECT ISOLATED CONVECTION MAINLY FOR AREAS ALONG AND SOUTH OF THE HWY 84 CORRIDOR SUNDAY AFTERNOON. STUCK PRETTY CLOSE TO GUIDANCE THROUGH THE PERIOD...BUT DID RAISE POPS SLIGHTLY ON SATURDAY TO INDICATE ISOLATED STORMS ALONG AND WEST OF I-55. DID NOT MAKE ANY CHANGES PAST SUNDAY NIGHT...SO WILL ATTACH THE PREVIOUS LONG TERM BELOW. /15/ .LONG TERM...A DRY VARIANT OF A TYPICAL SUMMERTIME PATTERN FOR THE LOWER MISSISSIPPI VALLEY REGION WILL TAKE HOLD AT THE START OF NEXT WEEK...PROBABLY LASTING THROUGH MOST OF NEXT WORK WEEK. ALOFT THE TURBULENT WESTERLIES WILL BE WELL NORTH OF THE AREA WHILE WEAK SUGGESTIONS OF A TROUGH TO OUR WEST BRING BETTER CHANCES OF INCLEMENT WEATHER IN PLACES THAT GENERALLY NEED IT MORE THAN HERE. UPPER LEVEL RIDGING WILL BUILD INITIALLY ATOP OUR AREA ON SUNDAY AND MONDAY...BUT THEN WILL REALLY BECOME A HOT FORCE TO OUR NORTH AS THE ANOMALY CENTER BLOSSOMS OVER THE OHIO VALLEY AND CENTRAL APPALACHIANS. IN OUR NECK-OF-THE-WOODS...THE GULF WILL REMAIN QUITE MOIST BUT PERSISTENT SOUTHEAST LOW LEVEL FLOW VECTORS WILL KEEP BEST MOISTURE SHUNTED WESTWARD INTO TEXAS AND THE SOUTHERN PLAINS. CONSIDERING THAT AND THE AFOREMENTIONED UPPER LEVEL WEAKNESS IT COULD BE RATHER WET FOR MANY OUT IN THE THAT DIRECTION NEXT WEEK...BUT REALLY ONLY OUR SOUTHERN AND SOUTHWESTERN AREAS HAVE THE ONLY DECENT CUMULATIVE SHOT AT A STRAY AFTERNOON SHOWER OR STORM. FORTUNATELY...WITH SUBSIDENCE FROM RIDGING ALOFT NOT TOO STRONG OVER THE ARKLAMISS AND FLOW FROM THE SOUTHEAST...TEMPERATURES FROM THE RESULTING REGIME SHOULD BE ONLY SLIGHTLY ABOVE SEASONAL AVERAGES AT WORST. MODEL CONSENSUS STILL HINTS BROADLY AT SOME SORT OF LOW PRESSURE DEVELOPMENT IN THE GULF LATER NEXT WEEK...WHICH IS QUITE CONCEIVABLE CONSIDERING TEMPORARILY FAVORABLE MJO PHASING. WITH THAT LOOSELY IN MIND...ALONG WITH MODEL CONSENSUS SUGGESTIONS OF AN INCOMING TROUGH OR WEAK FRONT...RAIN CHANCES WILL PROBABLY BE GOING UP AGAIN BY THE END OF NEXT WEEK. /BB/ && .AVIATION...A FEW TSTMS HAVE DEVELOPED OVER CENTRAL MS AND ISOLATED TSTMS WILL BE POSSIBLE THIS AFTN AND EARLY EVNG GENERALLY ALONG AND SOUTH OF I-20. ELSE...VFR CONDITIONS WERE BEING OBSERVED AT ALL TAF SITES AND WILL PREVAIL AREAWIDE THROUGH SATURDAY. HOWEVER...PATCHY AREAS OF LATE NIGHT/EARLY MORNING FOG WILL BRING BRIEF MVFR RESTRICTIONS AGAIN SATURDAY. DRIER AIR MOVING INTO THE AREA SATURDAY WILL PRECLUDE TSTM CHANCES AT THE TAF SITES THEN. /22/ && .PRELIMINARY POINT TEMPS/POPS...
