NWS Jackson, MS wrote its last area forecast discussion before the first event at Jun 29, 2:40 PM CST, 4 hours 45 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE JACKSON MS 340 PM CDT TUE JUN 29 2010 .SHORT TERM...TONIGHT THROUGH THURSDAY NIGHT...LATEST SURFACE ANALYSIS HAS THE NEARLY STATIONARY FRONTAL BOUNDARY EXTENDING FROM NORTHEAST TEXAS ACROSS SOUTHEAST ARKANSAS AND INTO NORTHEAST MISSISSIPPI. THIS BOUNDARY WAS HELPING TRIGGER NUMEROUS STORMS OVER OUR DELTA REGION THAT WERE NOT MOVING MUCH. ALTHOUGH THE INTENSITY OF THE STORMS IS EXPECTED TO REMAIN LIMITED THIS EVENING...SOME LOCALLY HEAVY RAINFALL WILL BE POSSIBLE. ELSEWHERE CONVECTION WAS MORE ISOLATED OVER THE CWA THIS AFTERNOON THAN EXPECTED. A WEAK OUTFLOW BOUNDARY FROM MORNING CONVECTION ALONG THE GULF COAST HAS MOVED INTO CENTRAL MISSISSIPPI AND WAS HELPING SET OFF SOME CONVECTION. THE 18Z JAN SOUNDING INDICATED LESS INSTABILITY TODAY THAN YESTERDAY ALONG WITH A WEAK CAP AT 800 MB. MOST OF THE CONVECTION WILL DISSIPATE SHORTLY AFTER SUNSET BUT THE PROXIMITY OF THE STALLED FRONT MAY STILL SET OFF SOME ACTIVITY IN THE NORTH WHILE SOUTHERLY FLOW BRINGS ADDITIONAL CONVECTION UP FROM THE GULF THROUGH THE NIGHT. WATER VAPOR IMAGERY/RUC ANALYSIS SHOWS A LARGE AMPLITUDE RIDGE ALOFT CENTER OVER THE CENTRAL CONUS THAT IS EXPECTED TO SHIFT EAST DURING THE SHORT TERM. AS THE RIDGE SHIFTS EAST IT WL HELP STRENGTHEN THE SURFACE HIGH CENTERED OVER THE NORTHERN PLAINS AND HELP PUSH THE STALLED COLD FRONT FARTHER SOUTH INTO OUR AREA. THE GFS BRINGS THE DRIER AIR NORTH OF THE BOUNDARY A LITTLE FARTHER SOUTH INTO OUR AREA WEDNESDAY THAN THE NAM/ECMWF. THE GREATEST POPS WILL BE CARRIED ALONG AND SOUTH OF THE BOUNDARY THROUGH THURSDAY WHICH SHOULD MEANDER BETWEEN HIGHWAY 82 AND THE INTERSTATE 20 CORRIDOR. DEEP MOISTURE IN PART DUE TO THE CIRCULATION AROUND TROPICAL STORM ALEX WILL CONTINUE OVER THE SOUTHERN HALF OF OUR AREA. THE ABUNDANT CLOUD COVER AND RAIN CHANCES ARE EXPECTED TO LIMIT INSOLATION WEDNESDAY AND THURSDAY AND BRING ABOUT NEAR NORMAL AFTERNOON HIGHS. THE LATEST GFS GUIDANCE CAME IN A LITTLE TOO WARM FOR WEDNESDAY. HAVE CUT MAX TEMPS A COUPLE OF DEGREES AT MOST SITES. THE GFS TRIES TO DEVELOP A SURFACE LOW OVER SOUTHERN MISSISSIPPI THURSDAY THAT THE UKMET HINTS AT BUT FARTHER EAST. THE NAM AND ECMWF ARE STRONGER WITH THE HIGH PRESSURE TO OUR NORTH AND DO NOT SHOW THE SFC LOW. HAVE LEANED TOWARD THE NAM/ECMWF FOR THURSDAY WHICH TRANSLATES INTO CONTINUED LOWER POPS FOR THE NORTHERN HALF OF OUR CWA. /22/ .LONG TERM...FRIDAY THROUGH TUESDAY...THE MODELS DEVELOP A LARGE UPPER RIDGE OVER THE ERN U.S. FRIDAY. THE EURO CENTERS THE UPPER RIDGE FARTHER N...MAINTAINING A WEAK UPPER TROUGH ACROSS THE NRN GULF WHILE THE GFS POSITIONS THE RIDGE CENTER FARTHER N AND DEVELOPS A WEAK WAVE THAT SKIRTS ALONG THE SRN EDGES OF HIGH PRESSURE TO APPROACH THE FORECAST AREA FROM THE EAST FRIDAY AFTERNOON. ALTHOUGH THE GFS DEVELOPS A STRONGER CLOSED LOW SYSTEM AT LOW LEVELS...THEY BOTH MAINTAIN LOW LEVEL TROUGHING NEAR THE COAST THAT WILL MAINTAIN THE BEST RAIN CHANCES OVER SRN ZONES. MEX POPS REMAIN HIGHER FRIDAY NIGHT IN RESPONSE TO ASCENT ASSOCIATED WITH THE ARRIVAL OF THE UPPER LOW. WILL MAINTAIN RAIN CHANCES INTO FRIDAY NIGHT BUT LOWER MEX POPS...ESPECIALLY NRN ZONES...FOR THAT PERIOD DUE TO UNCERTAINTY OF STRENGTH OF THE UPPER LOW COMPARED TO EURO/GFS ENSEMBLE SOLUTIONS THAT SUGGEST STRONGER RIDGING. CONFIDENCE IN THE HOLIDAY WEEKEND FORECAST IS REDUCED AS MODEL DIFFERENCES CONTINUE...THE GFS HOLDING ON TO UPPER TROUGHING OVER THE REGION WHILE THE EURO HOLDS ONTO STRONGER RIDGING. ALTHOUGH THE GFS LOOKS TOO STRONG WITH THE LOW CENTER IT DEVELOPS FOR SRN ZONES...SCATTERED POPS DO NOT LOOK UNREASONABLE FOR SRN ZONES SATURDAY AND SUNDAY PER THE GFS SOLUTION CONSIDERING THE AIR MASS WILL REMAIN MOIST AND SEA BREEZE EFFECTS MAY CONTRIBUTE TO HIGHER POPS SOUTH. CUT MOS NUMBERS SLIGHTLY FOR NRN ZONES LEAVING MORE ISOLATED ACTIVITY THOSE AREAS AS THE EURO AND GFS ENSEMBLE SHOWING STRONGER RIDGING...AS WERE THE LAST PERIODS OF THE SREF. CUT MEX NUMBERS A LITTLE MORE FOR MONDAY WHEN ALL MODELS SUGGEST THAT DRIER AIR WILL BEGIN TO WORK IN FROM THE EAST. ADJUSTED MEX TEMPS SLIGHTLY WARMER TO ACCOUNT FOR LOWER POPS AND IN CONSIDERATION OF LESS INTENSE TROUGHING THAN DEPICTED BY THE GFS. GENERALLY FOLLOWED THE HIGH GFS ENSEMBLE SOLUTIONS...ESPECIALLY FOR AFTERNOON HIGHS. ALSO DECREASED WINDS FRIDAY INTO THE WEEKEND A BIT TO REFLECT A SLIGHTLY MORE RELAXED PRESSURE GRADIENT. /03/ && .AVIATION...ISOLATED TO SCATTERED SHOWERS AND STORMS WILL CONTINUE TO BE POSSIBLE THIS AFTERNOON...ESPECIALLY ACROSS THE DELTA REGION...I.E. KGLH AND GWO. THIS ACTIVITY WILL REDUCE BOTH CEILINGS AND VISIBILITIES TO AT LEAST MVFR/IFR STATUS WHEN IT'S OBSERVED. THIS ACTIVITY WILL BEGIN TO DISSIPATE THROUGH THE EVENING AS DAYTIME HEATING IS LOST. VFR CONDITIONS ARE THEN EXPECTED TO PREVAIL AT MOST LOCATIONS OVERNIGHT...WITH ANOTHER ROUND OF ISOLATED MVFR/IFR CEILINGS AND/OR VISIBILITIES POSSIBLE AROUND DAY BREAK WEDNESDAY MORNING DUE TO PATCHY FOG AND LOW STRATUS. /19/ && .PRELIMINARY POINT TEMPS/POPS...
