AREA FORECAST DISCUSSION...CORRECTED NATIONAL WEATHER SERVICE HUNTSVILLE AL 1057 AM CDT WED JUL 23 2008 .UPDATE... DECREASED POPS FOR THE MORNING PERIOD...AND QPF THROUGH 00Z TO FOLLOW CURRENT TRENDS. && .DISCUSSION... TRICKY FORECAST IS UNFOLDING FOR THE REST OF TODAY. THE COLD FRONT THAT IS APPROACHING THE TENNESSEE VALLEY IS CURRENTLY DRAPED ALONG THE OHIO RIVER VALLEY...EXTENDING THROUGH KENTUCKY...MISSOURI...AND INTO SERN KANSAS. DRY AIR ASSOCIATED WITH THIS FRONT IS ALREADY KNOCKING ON THE DOORSTEP IN SRN MIDDLE TN...AND WILL CONTINUE TO WORK INTO THE AREA THIS AFTERNOON. STORM POTENTIAL IS THE TRICKY PORTION OF THE FCST FOR THIS AFTN/EVENING. FORCING ASSOCIATED WITH THE FRONT WILL ALLOW CONVECTION TO DEVELOP ARND MIDDAY. AS OF 15Z...CONVECTION HAS BEEN MAINLY RESTRICTED TO AREAS S OF THE CWA. MODEL DATA IS NOT SUGGESTIVE OF WIDESPREAD CONVECTION THIS MORNING DUE TO WEAK CONVERGENCE...BUT WITH THE HEATING OF THE DAY...EXPECT TO SEE COVERAGE INCREASE ACROSS THE AREA. MAIN QUESTION REVOLVES AROUND EXACTLY WHERE...AND TO WHAT EXTENT THE COVERAGE WILL BE ACROSS THE AREA THIS AFTN/EVENING. WITH PWATS THIS AFTN RANGING FROM 1.5 TO 2...HEAVY RAIN POTENTIAL WILL HAVE TO BE MONITORED...ESPECIALLY IN AREAS THAT RECEIVED SEVERAL INCHES OF RAINFALL WITH THE ACTIVITY YESTERDAY. IN ADDITION...WITH THE DRIER AIR ALOFT PUSHING ITS WAY INTO THE CWA...AFTN MIXING WILL ALLOW DAMAGING WIND GUSTS TO BE POSSIBLE WITH ANY STRONGER STORMS THAT DEVELOP. WILL MONITOR THE SITUATION AND ISSUE MESOSCALE UPDATES IF NECESSARY THIS AFTN. && .PREV DISCUSSION... /ISSUED 545 AM CDT WED JUL 23 2008/ DISCUSSION... /ISSUED 403 AM CDT WED JUL 23 2008/ AS THE NRN STREAM RIDGE PUSHES BY TO OUR NORTH ON THURS...WINDS SHOULD REMAIN LIGHT NRLY. NOW THINKING THAT THERE WILL BE VERY LITTLE CHANCE FOR ANY CONVECTION...WITH VERY DRY AIR ALOFT AND A DECENT SUBSIDENCE INVERSION AROUND THE 700MB-800MB LYRS. FOR THURS NIGHT...A SHORT WAVE IN NW FLOW ALOFT MAY GENERATE DEEP CONVECTION OR MCS ACTIVITY IN THE MID-MISS/LOWER OH VALLEY REGION. THIS FEATURE IS EXPECTED TO CONTINUE TO MOVE THROUGH OUR AREA DURING THE OVERNIGHT HOURS. DONT HAVE HIGH CONFIDENCE THAT RESULTING CONVECTION WILL ACTUALLY SURVIVE ALL THE WAY INTO OUR AREA. NEVERTHELESS...THOUGHT IT WAS WORTHY TO AT LEAST MENTION AN ISOLD CHANCE. A WEAK FRONTAL BOUNDARY AGAIN WILL ENCROACH UPON THE AREA LATE FRIDAY INTO SAT. HAVE LEFT POPS AS IS FOR NOW WITH CHANCE MENTION ON FRIDAY IN THE HIGHER THETA-E AIRMASS...AND HAVE RETAINED A 20 POP FOR NOW ON SAT. LATEST THINKING IS THAT THE PROGRESSION OF EVENTS MAY BE A LITTLE SLOWER WITH THE FRONT STALLING PERHAPS TO OUR NORTH ON SAT...BUT WILL GO WITH PERSISTENCE FOR NOW UNTIL A CLEAR PICTURE EMERGES. THE REST OF THE PERIOD REMAINS A LITTLE MUDDLED...WITH SLIGHT CHANCES FOR CONVECTION EACH PERIOD...AS THE REGION WILL REMAIN PRIMARILY IN A FAIRLY MOIST SWRLY/WRLY FLOW REGIME AMIDST NWRLY FLOW ALOFT. MED RANGE GUIDANCE IS STILL PERSISTENT IN DIGGING AN ERN CONUS TROUGH EARLY/MID NEXT WEEK...AND PUSHING YET ANOTHER SFC FRONT INTO THE TN VALLEY AT THAT TIME. && .HUN WATCHES/WARNINGS/ADVISORIES... AL...NONE. TN...NONE. && PREV DISCUSSION...KDW DISCUSSION...12
