AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE HUNTSVILLE AL 925 PM CDT TUE JUL 31 2007 .UPDATE... ISOLATED AFTERNOON CONVECTION APPEARS TO HAVE FINALLY FLAMED OUT FOR THE NIGHT. MOSTLY CLEAR CONDITIONS PREVAIL ACROSS THE CWA RIGHT NOW...WITH A FEW HIGH CLOUDS NOTED ON IR SATELLITE IMAGERY AND REGIONAL METARS. NAM BUFR SOUNDINGS WERE ACTUALLY HANDLING THIS PRETTY WELL...SHOWING ENHANCED MOISTURE IN THE 25O-400 MB LAYER. YET AGAIN...HAZE IS LINGERING AROUND AND CAUSING VISIBILITIES TO FLUCTUATE BETWEEN 3SM- 6SM ACROSS MOST OF THE CENTRAL TENNESSEE VALLEY. FOR TONIGHT...WE WILL UPDATE THE ZONES TO REMOVE PRECIP WORDING...AND TO ADD HAZE FOR ALL AREAS. VERY MINOR ADJUSTMENTS WILL BE MADE TO THE OVERNIGHT LOWS. EVERYTHING ELSE LOOKS JUST FINE. UPDATED GRIDDED AND TEXT PRODUCTS WILL BE OUT SHORTLY. DL-16 && .PREV DISCUSSION... FORECAST IS PRIMARILY PERSISTENCE FOR THE REST OF THE WORK WEEK. THE REGION WILL FEEL THE INFLUENCE OF SURFACE HIGH PRESSURE MOVING TO OUR NORTH AND WEST AS AN UPPER LEVEL RIDGE SLOWLY DRIFTS ACROSS THE AREA. BEING ON THE FRINGE OF THIS SURFACE HIGH...WITH EASTERLY FLOW AROUND THE SOUTHERN APPALACHIANS...AN ISOLATED SHOWER OR THUNDERSTORM CANNOT BE RULED OUT IN THE AFTERNOON/EARLY EVENING HOURS EACH DAY. HOWEVER...COVERAGE IS EXPECTED TO BE LIMITED. TEMPERATURES FOR THE NEXT SEVERAL DAYS WILL BE A COUPLE DEGREES ABOVE CLIMO FOR EARLY AUGUST. A WEAK SURFACE LOW ACROSS SOUTHERN ALABAMA/MISSISSIPPI WILL DRIFT UNDER THE UPPER LEVEL RIDGE FOR THE NEXT SEVERAL DAYS. AS IT MOVES OUT INTO THE NORTHERN GULF OF MEXICO...IT WILL BECOME MORE ORGANIZED...WITH ENERGY SUPPORT AT UPPER LEVELS...AND BEGIN TO MOVE NORTHWARD IN A WEAKNESS IN THE RIDGE. IT IS CURRENTLY PROGGED TO MOVE NORTH ACROSS ALABAMA OVER THE UPCOMING WEEKEND. HOWEVER... WITHOUT MUCH CONTINUITY FROM RUN TO RUN...HAVE ONLY INCLUDED SLIGHT CHANCE POPS IN THE LOCAL FORECAST FOR SATURDAY AND SUNDAY. IN THE FAR EXTENDED...ANOTHER FRONTAL SYSTEM IS FORECAST TO APPROACH THE REGION AS A LONGWAVE TROUGH DEEPENS ACROSS THE GREAT LAKES AND SOUTHERN CANADA.
