AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE HUNTSVILLE AL 1042 AM CDT FRI JUN 29 2007 .UPDATE... LATEST WATER VAPOR IMAGERY AND RUC ANALYSIS SHOWING UPPER RIDGING ELONGATED FROM THE CENTRAL GULF COAST EWRD THROUGH THE WESTERN ATLANTIC...WITH A QUASI-STATIONARY UPPER LOW OVER TX/OK. A SW-NE SHEAR AXIS AND SFC FRONT EXTEND ACROSS THE MID MISS/OHIO VALLEYS... WITH THIS BOUNDARY SLOWLY SINKING SOUTHWARD. CLOSER TO HOME...LATEST OBS SHOWING TEMPERATURES IN THE MID 80S TO NR 90...AND DEWPTS IN THE UPR 60S/LWR 70S. CONDITIONS THROUGH EARLY EVENING WILL BE VIRTUALLY A CARBON COPY OF THE PAST SEVERAL DAYS. SUSTAINED DEEPER MOISTURE AND HIGH CONDITIONAL INSTABILITY WILL PROVIDE ANOTHER ROUND OF DIURNALLY DRIVEN CONVECTION DURING PEAK HEATING. THE INCREASINGLY DIFFUSE SFC FRONT WILL ALSO DRIFT INTO THE AREA LATE TODAY...PROVIDING AN ADDED FOCUS FOR DEVELOPMENT. WITH THIS IN MIND...OVERALL PCPN COVERAGE MAY BE A TAD HIGHER THAN IN RECENT DAYS...AND WILL THUS MAINTAIN THE CURRENT 40% CHANCE. LATEST SOUNDING DATA ONCE AGAIN INDICATES THE POTENTIAL FOR ISLTD PULSE STORMS TO CONTAIN MICROBURSTS. BASED ON CURRENT TRENDS...WILL ADJUST HIGHS UPWARD ALL AREAS FOR THIS AFTERNOON. UPDATED TEXT/GRIDS OUT BY 16Z... MR && .PREV DISCUSSION... /ISSUED 405 AM CDT FRI JUN 29 2007/ SHORT TERM (THROUGH SUNDAY)... THE SFC FRONT WILL MOVE SLOWLY TO THE SOUTH...AND PROVIDE A FOCUS FOR SHOWER AND THUNDERSTORM ACTIVITY ACROSS THE TENNESSEE VALLEY THROUGH SATURDAY. THE FRONT WILL BECOME DIFFUSE AS IT MOVES INTO THE NORTHERN ALABAMA AREA...WITH ANY ASSOCIATED SFC CONVERGENCE BECOMING WEAK. HOWEVER...POOLING OF LOW LEVEL MOISTURE AND SUFFICIENT DAYTIME HEATING WILL ALLOW FOR SCATTERED CONVECTION TODAY AND SATURDAY. STILL BELIEVE THAT ACTIVITY WILL MOSTLY BE DIURNALLY DRIVEN...SO KEPT POPS HIGHER IN AFTN/EVENING TO REFLECT GREATER INSTABILITY DURING DAYTIME HEATING. 00Z NAM/GFS FCST SOUNDINGS INDICATE GUSTY WINDS UP TO 50 MPH...AND PERHAPS SMALL HAIL WILL BE POSSIBLE IN STORMS TODAY AND SATURDAY. ENVIRONMENTAL FLOW WILL BE QUITE WEAK AGAIN...SO SLOW MOVING STORMS WILL BE CAPABLE OF PRODUCING HEAVY RAINFALL WHERE THEY OCCUR. ISOLATED AMOUNTS GREATER THAN 1.5 ARE CERTAINLY POSSIBLE. FOR SUNDAY...GFS ADVERTISING A LITTLE MORE RESIDUAL MOISTURE IN THE WAKE OF THE FRONT...AND RELATIVELY STRONG SHORT WAVE MOVING THROUGH THE AREA DURING DAYTIME HEATING MAXIMUM. THIS WILL LEAD TO DEVELOPMENT OF SCATTERED STORMS AGAIN ON SUNDAY AFTERNOON...SO INCREASED POPS A LITTLE ESPECIALLY IN SOUTHERN AREAS ON SUNDAY. WOULDNT BE SURPRISED TO SEE MORE STRONG WINDS AND MAYBE SOME SMALL HAIL IN STORMS AGAIN ON SUNDAY. LONG TERM (MONDAY THROUGH FRIDAY)... ELECTED TO GO WITH GFS/ECMWF BLEND FOR LONGER RANGE. 00Z GFS SHOWS GOOD DRY PUNCH OF AIR ON MONDAY AS AREA WEATHER BECOMES DOMINATED BY POLAR HIGH MOVING ACROSS THE LAKES REGION. DRY WEATHER EXPECTED TO CONTINUE THROUGH WEDNESDAY. KEPT TEMPS A LITTLE ABOVE GUIDANCE GIVEN PROPENSITY FOR THIS DURING THE ONGOING DROUGHT SITUATION. MODELS ARE SHOWING SOME CONSISTENCY IN DEVELOPING A WESTERN CONUS RIDGE/EAST CONUS TROUGH LATE IN THE PERIOD AND DRIVING A SFC FRONT AGAIN THROUGH THE OHIO AND TN VALLEYS BEGINNING ON THURSDAY. MOISTURE RETURN INTO THE REGION AROUND THE WESTERN AND NORTHERN FLANK OF A GULF HIGH PRESSURE SYSTEM...COUPLED WITH YET ANOTHER IN A SERIES OF POTENTIAL FRONTAL PASSAGES WILL GENERATE SOME SHOWER/TSRA ACTIVITY FOR THE MID SOUTH AGAIN THURSDAY THROUGH FRIDAY...AND PERHAPS LASTING INTO THE WEEKEND.
