NWS Jackson, MS wrote its last area forecast discussion before the first event at Jul 27, 1:50 PM CST, 3 hours 41 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON MS 250 PM CDT WED JUL 27 2011 .SHORT TERM...THE PRIMARY CONCERNS WILL BE OUR CHANCES OF RAINS WITH LOCALLY HEAVY DOWN POURS FROM SLOW MOVING THUNDERSTORMS...FOLLOWED BY HEAT INDEX VALUES AS WELL AS POPS AND TEMPS. LATEST SATELLITE IMAGERY SHOWS THE MEAN RIDGE WAS CENTERED OVER THE MIDSOUTH REGION...WHILE THE ARKLAMISS WAS UNDER A WEAK AREA OF THE UPPER RIDGE WITH AN INVERTED TROUGH TO THE WEST. VAPOR IMAGERY SHOWED SOME MIDLEVEL DRYING EXTENDING SOUTH TO AROUND TOWARD HIGHWAY 84 GOING TO INTERSTATE 20 IN CENTRAL MISSISSIPPI. A WEAK DISSIPATING LOW LEVEL BOUNDARY WAS ALSO NOTED ACROSS THE CENTRAL PORTION OF THE ARKLAMISS REGION. AREA RADARS HAVE BEEN PICKING UP SOME ISOLATED TO SCATTERED CONVECTION TRACKING WEST IN LOW LEVEL EASTERLY FLOW. THE MAIN AREA OF CONVECTION WAS NOTED ALONG THE COASTAL AREAS. THIS WAS BEING ASSISTED BY SOME ISENTROPIC LIFT FROM THE EAST. FOR THE REMAINDER OF THE AFTERNOON EXPECT THE BEST CHANCES OF RAIN TO STAY SOUTH OF INTERSTATE 20. WITH SO MUCH PRECIPITABLE WATER WILL LOOK FOR THE POTENTIAL FOR SOME LOCALLY HEAVY DOWN POURS. WILL PUT IN PRE-EVENING WORDING FOR THE ZONES. ALSO REDUCED POPS SOME IN THE SOUTH FOR THE PRE-EVENING WORDING. FOR TONIGHT THROUGH FRIDAY NIGHT...EXPECT THE CONVECTION TO GRADUALLY DIMINISH AFTER SUNSET. THERE WILL BE THE POTENTIAL FOR ISOLATED SHOWERS GENERALLY ALONG AND SOUTH OF INTERSTATE 20 OVERNIGHT. LOWS WILL BE IN THE LOWER TO MIDDLE 70S. OTHERWISE FOR THE PERIOD EXPECT A SERIES OF WEAK DISTURBANCES TO CROSS THE REGION FROM THE EAST. THE MODELS KEEP DECENT CHANCES OF RAIN AROUND FOR THURSDAY...BUT TRY TO DRY POPS OUT ON FRIDAY SOME. THE EURO AND SREF MODELS KEEPS SOME DECENT QPF COVERAGE FOR FRIDAY. WITH PRECIPITABLE WATER BEING AROUND 2 INCHES FOR THE PERIOD...AM INCLINE TO KEEP AT LEAST SCATTERED POPS ON FRIDAY PER THE EURO AND SREF MODELS. SHORT RANGE MODELS SHOWS THAT THE MEAN RIDGE CENTER WILL ROTATE TOWARD THE GULF COASTAL REGION ON FRIDAY-FRIDAY NIGHT. THIS IS WHY THE MODELS CUT DOWN POPS SOME. THE NATIONAL AND LOCAL WRF MODELS KEEPS THE BEST CHANCES OF RAIN IN THE SOUTH FOR THE PERIOD...WHICH SEEMS REASONABLE. HEAT INDEXES WILL BE ON THE RISE SOME THROUGH THE SHORT TERM AS THE MEAN RIDGE CENTER PUSHES TOWARD THE REGION FROM THE APPALACHIANS WITH VALUES OF 105-108 DEGREES. FOR RIGHT NOW WILL NOT ISSUE ANY HEAT ADVISORIES FOR THE PERIOD. AS FAR AS TEMPS ARE CONCERN USED A BLEND OF ENSEMBLES...GMOS AND MAV GUIDANCE. HIGHS WILL BE IN THE LOWER TO MIDDLE 90S ON THURSDAY AND FRIDAY. WITH THIS HUMID AIRMASS LOWS WILL BE IN THE LOWER TO MIDDLE 70S./17/ ./PREVIOUS LONG TERM...SATURDAY THROUGH WEDNESDAY...MODEL CONSENSUS SHOWS AN EASTERLY WAVE/POSSIBLE TROPICAL LOW ROUNDING THE HIGH AND OVER THE WESTERN GULF WATERS. THIS FEATURE WILL LIKELY BE TOO FAR WEST OF OUR CWA TO IMPACT OUR WEATHER BUT DAYTIME HEATING SHOULD AGAIN LEAD TO A DECENT COVERAGE OF SHOWERS AND THUNDERSTORMS WITH THE GREATEST POPS BEING CARRIED ACROSS THE SOUTHERN HALF OF OUR CWA. AFTERNOON HIGHS SHOULD BE NEAR NORMAL IN THE LOWER 90S AT MOST SITES. SATURDAY BOTH THE HIGH SURFACE AND ALOFT WILL TRACK WEST ACROSS OUR CWA. DRIER AIR ALOFT WITH PWS JUST BELOW TWO INCHES IS PROGGED TO MOVE NORTH INTO OUR AREA FROM THE SOUTH. TEMPERATURES WILL TOP OUT SEVERAL DEGREES WARMER SATURDAY. DUE TO INCREASED SYNOPTIC SUBSIDENCE AND LOWER PWS...COVERAGE OF CONVECTION WILL LIKELY BE LESS BUT ISOLATED MAINLY AFTERNOON AND EVENING STORMS WILL BE POSSIBLE. SUNDAY AND MONDAY THE MID LEVEL HIGH LOOKS TO STRENGTHEN AND BECOME CENTERED OVER THE SOUTHERN PLAINS WHILE SURFACE RIDGING PERSISTS OVER OUR CWA. GRADUALLY WARMER TEMPERATURES AND LOWER POPS WOULD BE THE NORMAL RESULT BUT THE GFS AND TO A WEAKER EXTENT...THE ECMWF...SHOW A POTENT SHORTWAVE IN THE NORTHWEST FLOW ALOFT THAT MAY ENHANCE CONVECTION IN THE NORTHWEST LATE SUNDAY AND SUNDAY NIGHT AND THEN ENHANCE CONVECTION OVER THE SOUTHERN PORTIONS OF OUR CWA MONDAY. THE GFS IS SHOWING PWS IN EXCESS OF TWO AND A QUARTER INCHES OVER OUR CWA BY MONDAY. CLOUDS AND RAIN MAY LIMIT INSOLATION BUT WL CONTINUE TO MENTION HIGH HEAT INDEX VALUES DURING THE PERIOD IN THE HWO AS FORECAST VALUES STILL EXCEED 105 SUNDAY AND MONDAY AFTERNOONS. TUESDAY AND WEDNESDAY THE MID LEVEL HIGH LOOKS TO WEAKEN AND FLATTEN ACROSS THE SOUTHERN STATES. WARMER THAN NORMAL TEMPERATURES ARE EXPECTED ALONG WITH ABOVE NORMAL HUMIDITY LEVELS. DIURNAL RAIN CHANCES WITH GREATER COVERAGE ACROSS THE SOUTHERN HALF OF THE CWA WILL BE MOST LIKELY. /22/ && .AVIATION...VFR CONDITIONS CONTINUE AT MOST TAF SITES THIS AFTERNOON. SCATTERED SHOWERS AND STORMS ARE DEVELOPING AS EXPECTED. SITES THAT OBSERVE ANY OF THIS ACTIVITY WILL EXPERIENCE A BRIEF PERIOD OF MVFR/IFR CEILINGS AND/OR VISIBILITIES. KJAN...KMEI...AND KHBG HAVE THE BEST CHANCES FOR SEEING SCATTERED CONVECTION...WHICH COULD LINGER INTO THIS EVENING. FOR TONIGHT...VFR CONDITIONS ARE EXPECTED ONCE AGAIN. HOWEVER AS HAS BEEN THE CASE THE PAST SEVERAL MORNINGS...TOWARDS DAY BREAK THURSDAY ANOTHER BOUT OF MVFR/IFR CEILINGS AND/OR VISIBILITIES WILL BE POSSIBLE AT SOME SITES DUE TO LOW STRATUS AND PATCHY FOG. /19/ && .PRELIMINARY POINT TEMPS/POPS...
