Area forecast discussion, Aug 9, 2:20 PM CDT, 3 hours 37 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LITTLE ROCK AR 220 PM CDT THU AUG 9 2012 .DISCUSSION... MAIN CONCERNS THIS FORECAST CYCLE ARE FIRST PERIOD CHANCES OF CONVECTION AND ANY THREAT OF SEVERE STORMS. THEN NEAR NORMAL TEMPS FRIDAY AND INTO THE WEEKEND. THEN THE NEXT CHANCE OF RAIN ON SUNDAY TO MONDAY WITH THE NEXT FRONTAL BOUNDARY. THE WILD FIRE DANGER CONTINUES TO BE HIGH TO EXTREME DUE TO OVERALL DROUGHT AND DRY FUELS. THIS AFTERNOON...THE SURFACE BOUNDARY HAS MADE LITTLE PROGRESS SOUTH AND IS NEAR THE AR AND MO STATE LINE...THEN OVER NE OK. A SURFACE LOW WAS TRYING TO FORM OVER WESTERN AR BUT NOT A STRONG ONE BY ANY MEASURE. NORTH OF THE BOUNDARY...DRIER AND MORE STABLE AIR WITH A NW TO NE FLOW...WHILE SOUTH OF THE BOUNDARY...A S TO SW FLOW WITH DEW POINTS IN THE 60S CENTRAL TO LOWER 70S OVER SOUTHERN LOCATIONS. TEMPS WERE MOSTLY IN THE 90S. AMOUNT OF LIFT WITH FRONT AND UPPER SUPPORT REMAINS KEY TO AMOUNT OF CONVECTION THIS AFTERNOON TO EVENING. JET DYNAMICS ARE MARGINAL WITH MAIN UPPER DIFFLUENCE PUSHED WELL EAST AND LOW LEVEL JET IS WEAK. && .SHORT TERM...TONIGHT THROUGH SUNDAY NIGHT WILL START THE FORECAST WITH A SLIGHT CHANCE MAINLY OVER NORTHERN AR...WHILE A CHANCE CENTRAL AND SOUTH THIS EVENING. AFTER CONVECTION INITIATION WILL HAVE TO FINE TUNE COVERAGE AND AMOUNT WITH POSSIBLE UPDATE. SLIGHT RISK OF SEVERE STORMS WILL BE POSSIBLE OVER THE AREA DUE TO AVAILABLE MOISTURE AND INSTABILITY... ESPECIALLY OVER SOUTHERN AR A BIT LATER THIS EVENING. MAIN CONCERN WILL BE DAMAGING WINDS WITH LESSER HAIL THREAT. AS THE FRONT SAGS SOUTH TONIGHT...CONVECTION CHANCES GO WITH IT AND POP TREND SHOWS THIS. ON FRIDAY SOME LINGERING CONVECTION OVER FAR SOUTHERN AR BUT THIS CONVECTION WILL GRADUALLY DRIFT SOUTH OUT OF AR. A COOLER AND DRIER AIR MASS THEN FILTERS INTO AR AND LOWERS TEMPS A BIT BELOW TO AROUND NORMAL VALUES. THE SURFACE RIDGE THEN GRADUALLY MOVES EAST INTO SUNDAY...WHILE SOME RETURN FLOW COMES BACK TO AR ON SUNDAY. THEN NEXT CHANCE OF RAIN MATERIALIZES LATE SUNDAY AS THE WEAK FRONT LIFTS AS A WARM FRONT AND THE NEXT COLD FRONT APPROACHES FROM THE NW ON MONDAY. && .LONG TERM...MONDAY THROUGH THURSDAY MODELS ARE IN A LITTLE LESS AGREEMENT FOR THE LONG TERM PERIOD THAN HAS BEEN SEEN OVER THE LAST FEW DAYS. NAMELY THE DISAGREEMENT IS IN HOW LONG THE MODELS HOLD ONTO THE PATTERN CHANGE THAT IS CURRENTLY UNDER WAY AS THE MEAN RIDGE SHIFTS WESTWARD. THE GFS HOLDS ON TO THIS PATTERN CHANGE AND BRINGS SEVERAL DISTURBANCES THROUGH THE AREA IN NW FLOW ALOFT. THE EURO BUILDS THE RIDGE EASTWARD BY LATE TUESDAY EVENING. HAVING SAID THAT...TEMPERATURES WILL REMAIN AROUND SEASONAL NORMS THROUGH THE LONG TERM...THOUGH POSSIBLY WARMING TO ABOVE NORMAL READINGS IF YOU BUY THE EUROPEAN. THOUGH SLIGHT TIMING DIFFERENCES ARE PRESENT...MOST GUIDANCE AGREES UPON BRINGING AN INITIAL DISTURBANCE THROUGH ON MONDAY. DID LIMIT RAIN CHANCES TO THE SLIGHT CHANCE CATEGORY B/C OF TIMING DIFFERENCES THOUGH...THEN LEFT SOME SLIGHT CHANCES IN THE SOUTHEAST MON NIGHT AS THE DISTURBANCE/FRONT MOVES OUT OF THE AREA. FOR EACH SUBSEQUENT DAY...HAVE BROAD-BRUSHED 20 POPS IN THE AFTERNOONS AND NO MENTION OF RAIN AT NIGHT. WHETHER YOU BELIEVE THE GFS OR THE WARMER EURO...SUMMERTIME CONVECTION WOULD BE POSSIBLE ANY AFTERNOON AND LIKELY DIE OFF AFTER SUNSET. && .PRELIMINARY POINT TEMPS/POPS...
