AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE HUNTSVILLE AL 1225 PM CDT TUE JUL 10 2012 .UPDATE... FOR 18Z TAFS && .DISCUSSION... /ISSUED 1046 AM CDT TUE JUL 10 2012/ WEAK DIFFUSE SFC BOUNDARY REMAINS FAIRLY STAGNANT ACROSS THE LOWER OH VALLEY WWD INTO THE SRN PLAINS THIS LATE MORNING...WITH CONVECTION DEVELOPING INVOF THE FRONT ITSELF. THIS BOUNDARY IS XPCTED TO REMAIN NEARLY STATIONARY BASED ON THE LATEST/INTERMEDIATE GUIDANCE. WITH ABUNDANT MOISTURE IN PLACE ALONG AND S OF THE FRONT...ADDITIONAL CONVECTION SHOULD BEGIN TO DEVELOP ACROSS THE NRN/ERN HALF OF THE FORECAST AREA LATER TODAY. IN FACT...SOME CONVECTION HAS ALREADY DEVELOPED ALONG THE ERN TN PLATEAU LEADING INTO EXTREME NE AL. AS WITH MON...PRECIP MAY BE SLOW TO DEVELOP SWD GIVEN THE WEAK FLOW PATTERN IN PLACE ACROSS THE REGION. IN ANY CASE...SCT SHOWERS/TSTMS LOOK REASONABLE FOR NRN AL...WITH PERHAPS CONVECTION TRENDING MORE IN THE LIKELY CAT ACROSS SRN MID TN. AFTERNOON TEMPS SHOULD ALSO BE MORE SEASONAL...GIVEN THE DEVELOPING PRECIP COUPLED WITH INCREASING CLOUD COVER. MORNING FORECAST HAS BEEN UPDATED TO REFLECT THESE ONGOING WX TRENDS...ALONG WITH REFRESHING SOME OF THE CURRENT/HOURLY GRIDS. OTHERWISE...NO FURTHER/MAJOR CHANGES ARE XPCTED ATTM. 09 && .AVIATION... FOR 18Z TAFS...SCT/NUM SHOWERS/TSTMS CONTINUE TO DEVELOP ALONG A WEAK SFC BOUNDARY DRAPED W TO E ACROSS THE AL/TN STATE LINE. CONVECTION HAS YET TO AFFECT THE TWO MAIN TERMINALS...ALTHOUGH THE PROB WILL EXISTS INTO THE EVENING HRS AS THE FRONT DRIFTS SWD. GENERALLY VFR CONDS ARE XPCTED FOR MUCH OF THE PERIOD...ALTHOUGH AMD/UPDATES MAY BE REQUIRED PROVIDED ANY OF THE PRECIP APPROACHES ONE OF THE TAF SITES. 09 && .PREV DISCUSSION... /ISSUED 359 AM CDT TUE JUL 10 2012/ LATEST WATER VAPOR IMAGERY AND H5 RUC ANALYSIS INDICATE RIDGING PREVAILS ACROSS MUCH OF THE INNER MOUNTAIN WEST...WITH BROAD CYCLONIC FLOW ACROSS THE GREAT LAKES STATES AND NORTHEAST. AT THE SURFACE...A STALLED BOUNDARY IS DRAPED FROM EASTERN OKLAHOMA INTO THE CAROLINAS BY WAY OF MIDDLE TENNESSEE. THE MAJORITY OF THE PRECIPITATION IN THE SOUTHEAST IS ASSOCIATED WITH THIS BOUNDARY ATTM...HOWEVER EARLIER WARM SECTOR DIURNALLY- AND OUTFLOW-DRIVEN THUNDERSTORM COMPLEXES DEVELOPED. THE MAIN STORY FOR TODAY...AND REALLY THE REST OF THE WEEK...WILL CENTER ON WET UNSETTLED WEATHER. LACKING IN UPPER LEVEL SUPPORT...THE STALLED FRONT WILL MAKE LITTLE IN THE WAY OF SOUTHWARD PROGRESS TODAY...INSTEAD HANGING JUST NORTH OF THE CWFA. GIVEN THIS EXPECTED SCENARIO...DECIDED TO REDUCE RAIN CHANCES FOR MUCH OF THE AREA...WITH THE SLIMMEST CHANCES IN THE SOUTHEAST PORTION OF THE CWFA. SOUNDINGS SUGGEST THAT THE STRONGER STORMS THIS AFTERNOON...WHERE SPURRED BY OUTFLOW OR DIFFERENTIAL HEATING BOUNDARIES...WILL BE CAPABLE OF GUSTY WINDS AND FREQUENT LIGHTNING...IN ADDITION TO LOCALLY HEAVY RAINFALL. DIURNALLY DRIVEN THUNDERSTORMS WILL LINGER INTO THE EVENING...WITH ADDITIONAL SHOWERS/THUNDERSTORMS EXPECTED AS CONSIDERABLY GREATER MOISTURE TRANSPORT MOVES INTO THE AREA FROM CENTRAL MISSISSIPPI. MODELS ARE NOT IN TOTAL AGREEMENT WITH HOW THEY HANDLE THIS LOOSELY ORGANIZED CYCLONIC CIRCULATION...BUT MOST SUGGEST THE HIGHEST RAIN CHANCES /AS WELL AS RAIN TOTALS/ WILL BE IN THE WESTERN HALF OF THE CWFA. THE SYSTEM WILL CONTINUE TO MOVE NORTHEAST INTO THE CWFA ON WEDNESDAY...WITH BUFR SOUNDINGS SHOWING A VERY SATURATED ATMOSPHERE FOR ALL OF THE TENNESSEE VALLEY. THE WET WEATHER SHOULD CONTINUE ON WEDNESDAY NIGHT AND THURSDAY...AND MODELS CONTINUE TO SUGGEST THAT SOME LOCATIONS MAY SEE AROUND 3 INCHES OF RAIN BY THE END OF THE DAY THURSDAY. THE STALLED SURFACE FRONT WILL FINALLY LIFT NORTHWARD BY THURSDAY EVENING IN RESPONSE TO A SHORTWAVE MOVING THROUGH THE UPPER PLAINS. AS THIS OCCURS...THE TENNESSEE VALLEY WILL AGAIN FIND ITSELF IN THE WARM SECTOR...WITH A VERY OPEN GULF SPILLING AMPLE HEAT AND MOISTURE INTO THE AREA. DIURNALLY ENHANCED CONVECTION WILL RULE THE FORECAST THIS WEEKEND...ALONG WITH HIGHS AGAIN CREEPING INTO THE LOW 90S GIVEN INCREASED SUNSHINE AND A BUILDING UPPER RIDGE ACROSS THE LOWER PLAINS/SOUTHEAST STATES.
