AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE LITTLE ROCK AR 457 PM CDT MON AUG 21 2006 .UPDATE... NEAR TERM...RECENT RADAR TRENDS INDICATE SOME DECREASE IN INTENSITY SINCE 21Z. THE STRONGEST ACTIVITY APPEARS TO BE ALONG THE POPE/CONWAY COUNTY LINE...AS RADAR SIGNATURES SUGGEST DAMAGING WIND GUSTS ARE LIKELY. 55 && .PREV DISCUSSION.../ISSUED 314 PM CDT MON AUG 21 2006/ SHORT TERM...TONIGHT THROUGH FRIDAY MAIN CONCERN IN THE NEAR TERM IS COVERAGE...INTENSITY...AND DURATION OF CONVECTION THAT HAS DEVELOPED THIS AFTERNOON. RECENT OBSERVATIONAL DATA INDICATES SCATTERED TO NUMEROUS CONVECTIVE CELLS ACROSS THE WESTERN HALF OF THE FORECAST AREA. ACROSS CENTRAL AND SOUTHERN PORTIONS OF THIS AREA...THE ACTIVITY APPEARS TO BE DRIVEN BY SMALL SCALE FORCING. THE ACTIVITY NOW AFFECTING NORTHWESTERN ARKANSAS IS ORGANIZED AT THE MESOSCALE LEVEL...AND WILL LIKELY AFFECT ALL OF THE NORTHERN CWA BY EARLY EVENING. DAMAGING WIND GUSTS ARE EXPECTED WITH THE STRONGEST STORMS THOUGH EARLY EVENING. MOST OF THIS ACTIVITY IS EXPECTED TO DIMINISH SHORTLY AFTER SUNSET. A WEAK SURFACE BOUNDARY LOCATED ACROSS SOUTHERN PORTIONS OF THE FORECAST AREA WILL MOVE SLOWLY SOUTH THROUGH TUESDAY. SLIGHTLY COOLER...AND MORE STABLE CONDITIONS IS EXPECTED TO SLOWLY FILTER FROM NORTHEAST TO SOUTHWEST ACROSS THE FORECAST AREA THROUGH MID WEEK. LONG TERM...FRIDAY NIGHT THROUGH MONDAY MODELS ARE RATHER CHAOTIC IN THEIR SOLUTIONS IN THE EXTENDED TERM. THERE HAS BEEN LITTLE AGREEMENT BETWEEN THE MODELS FOR THE PAST SEVERAL DAYS AND POOR CONTINUITY BETWEEN MODEL RUNS. OVERALL THE MODELS SEEM TO BE HEADING FOR A SIMILAR SOLUTION...BUILDING A RATHER FLAT RIDGE UP ACROSS THE SERN US LATE IN THE EXTENDED TERM...BUT THEY DIFFER CONSIDERABLY ON HOW THEY GET THERE FROM THE PRESENT PATTERN. FOR THE EXTENDED FORECAST I AM GOING TO USE A BLEND OF THE MODELS AND CONSIDER THE AREA TO BE UNDER A PREDOMINANTLY ZONAL FLOW PATTERN...AND WILL ACCEPT THE SOLUTION OF A RIDGE BUILDING INTO THE AREA FROM THE SOUTHEAST BY SUNDAY AND MONDAY. DURING THE EXTENDED TIME FRAME...ITS LIKELY THAT SEVERAL SHORTWAVES WILL PASS ACROSS THE FORECAST AREA. THE CURRENT EXTENDED FORECAST HAS LOW POPS THROUGH MUCH OF THE PERIOD...AND I WILL GO AHEAD AND LEAVE THIS AS IS. AT THIS TIME RANGE...AND WITH THE MODELS IN A STATE OF DISAGREEMENT...ITS TOO DIFFICULT TO NAIL DOWN ANY AREAS WHERE THERE WILL BE GREATER CHANCES FOR PRECIP. IN ADDITION...THE LOWER LEVELS OF THE ATMOSPHERE WILL LIKELY BE FAIRLY MOIST SO AT THE VERY LEAST DAYTIME HEATING SHOULD PROVIDE AMPLE CHANCES FOR ISOLATED AFTERNOON CONVECTION. ONE OTHER POINT OF CONSIDERATION IN THE EXTENDED TIME FRAME IS A COLD FRONT THAT THE MODELS ARE BRINGING DOWN OVER THE WEEKEND. EARLIER RUNS HAD THE FRONT APPROACHING THE AREA ON SATURDAY...AND NOW THE MODELS ARE GENERALLY PUSHING IT INTO NRN ARKANSAS BY SUNDAY. ONCE AGAIN THE MODELS ARE HANDLING THE FRONT DIFFERENTLY AFTER THIS POINT...AND THERE HAS BEEN CONSIDERABLE VARIATION BETWEEN MODEL RUNS. AT THIS TIME I AM NOT EVEN CERTAIN IF THIS FRONT WILL MAKE IT MUCH FURTHER SOUTH THAN THE AR/MO BORDER. THE GFS AND EUROPEAN MODELS ARE BLOWING THE FRONT RAPIDLY THROUGH THE STATE AND BUILDING THE ASSOCIATED HIGH MUCH FURTHER SOUTH THAN THE DGEX...WHICH TAKES THE ASSOCIATED SURFACE HIGH AND MOVES IT ACROSS THE GREAT LAKES REGION. THE GFS AND EUROPEAN MODELS SEEM TO BE PUSHING THIS FRONT THROUGH MUCH TOO AGRESSIVELY...SO AT THIS POINT I AM GOING TO BE A LITTLE MORE CONSERVATIVE AND BRING IT INTO NRN AR AROUND SUNDAY MORNING AND STALL IT OUT SOMEWHERE ACROSS THE NORTHERN THIRD OF THE STATE...AND GRADUALLY PUSH IT BACK NORTH ON MONDAY. FRANKLY THIS IS A BEST GUESS AT THIS STAGE AND I WOULD NOT BE SURPRISED IF I HAVE TO MAKE WHOLESALE CHANGES TO THIS FORECAST PERIOD OVER THE NEXT SEVERAL DAYS. && .LZK WATCHES/WARNINGS/ADVISORIES...
