AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE HUNTSVILLE AL 329 PM CDT WED AUG 17 2005 .DISCUSSION... STRONG SHOWERS AND TSTORMS HAVE DEVELOPED ALONG A SFC TROUGH LOCATED ACROSS CENTRAL TN AND NORTHERN AL...MORE ORGANIZED CONVECTION CURRENTLY LOCATED IN NE AL AND CENTRAL TN. AS THIS TROUGH INTERACTS WITH DRIER AIR MOVING INTO THE LOWER MS VALLEY...CONVECTION COULD BECOME MORE ORGANIZED...AND A WATCH ISSUED PER SPC. AS FOR TONIGHT AND THE NEXT COUPLE DAYS...HIGH PRESSURE WILL CONTINUE TO RESIDE OVER THE SOUTHEAST. AS THE CENTER OF THE H5 RIDGE WOBBLES ALONG THE GULF COAST...SHORT WAVES WILL CONTINUE TO ROTATE AROUND IT KEEPING CHANCE POPS IN THE FORECAST. BEST CHANCE OF SHOWERS LOOKS LIKE IT WILL BE THURSDAY AFTERNOON AS A SHORTWAVE MOVES OVER THE REGION. WITH PWS STILL HIGH AND WEAK STORM MOTION...HEAVY RAIN WILL AGAIN BE THE MAIN THREAT. WITH A WETTER MID LEVEL...DOWNBURSTS WILL NOT BE AS BIG OF A THREAT AS THE PREVIOUS DAYS. AS THE RIDGE MAKES A SOLID EFFORT TO BUILD FURTHER TO OUR NORTHWEST ON FRIDAY AND SATURDAY...MODELS TEND TO WASH OUT ANY DISTURBANCES BEFORE THEY MAKE IT TO OUR AREA. THIS WILL KEEP POPS DOWN AND TEMPS IN THE MID TO HIGH 90S FOR MUCH OF THE WEEKEND. MODELS ARE STILL BRINGING A COLD FRONT THROUGH THE REGION EARLY NEXT WEEK...SOMETIME MONDAY MORNING. EVEN WITH THE CONTINUITY OF SEVERAL FORECAST RUNS...CURRENT THINKING IS THAT THEY ARE TOO AGGRESSIVE. TAKING CLIMO INTO ACCOUNT...FRONT PROBABLY WILL SLOW DOWN...IF NOT STALL OUT...WILL WAIT FOR A FEW MORE FORECAST RUNS TO MAKE ANY MAJOR CHANGES TO THE EXTENDED. WITH THAT SAID...DID NOT LOWER THE TEMPS AS MUCH AS GUIDANCE DID...KEPT MAXES IN THE HIGH 80S TO LOW 90S THROUGHOUT THE PERIOD. ALSO...TWEAKED MINS DOWN TO REFLECT A COOL FRONTAL PASSAGE...AND LOWERED DEWPOINTS ASSUMING WE WILL BE IN DRIER NORTHERLY FLOW BEHIND THE FRONT. HOWEVER...WITH THE POSSIBILITY OF THE FRONT STALLING NEAR OUR REGION...KEPT THE POSSIBILITY OF POPS IN FOR NOW. && .PRELIMINARY POINT TEMPS/POPS...
