NWS Huntsville, AL wrote its last area forecast discussion before the first event at Jul 13, 10:15 AM CST, 10 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE HUNTSVILLE AL 1115 AM CDT TUE JUL 13 2010 .UPDATE... EXPANDED LIKELY COVERAGE TO REST OF ALABAMA COUNTIES. && .DISCUSSION... MORE CONVECTION WAS AFFECTING THE TENNESSEE VALLEY THIS MORNING...AS A LINE OF SHOWERS/THUNDERSTORMS SWEEPS ACROSS NW ALABAMA. THIS LINE AS OF 11 AM EXTENDED FROM LAWRENCEBURG TN...TO THE QUAD CITIES AND EAST WEST OF RUSSELLVILLE. OTHER ACTIVITY WAS FORMING...WITH THE STRONGEST STORMS WEST OF SCOTTSBORO AND DECATUR. THE LOCAL SOUNDING FROM THE REDSTONE ARSENAL HAD 1.5 INCHES OF PRECIP WATER...DRIER THAN YESTERDAY'S PLUS 2 INCH READINGS. HOWEVER 2.2 INCHES PW AMOUNTS WERE NOTED NORTH OF HERE AT NASHVILLE...IN DEEPER MOISTURE. THE INFRARED/WATER VAPOR LOOP CONFIRMS THIS...WITH A VORT MAX MOVING ACROSS NE MS/TN BORDER. EXTENSIVE CLOUDS THUS FAR HAVE KEPT TEMPS DAMPED IN THE MID 70S OVER NW ALABAMA...WITH MID/UPPER 80S TOWARD FT PAYNE. NEEDLESS TO SAY...CONDITIONS ARE BECOMING MORE UNSTABLE OVER OUR EASTERN AREAS. THUS...SEVERE T-STORM WATCH #464 WILL BE ACTIVE FOR THE LOCATIONS EAST OF THE QUAD CITIES UNTIL 6 PM. HAVE ALREADY MADE CHANGES TO THE FORECAST FOR THIS AFTERNOON... MAINLY REGARDING RAIN CHANCES. HAVE INCREASED POPS TO LIKELY FOR THE REMAINDER OUR ALABAMA COUNTIES...AND THE CATEGORICAL FOR OUR TENNESSEE COUNTIES. HAVE LEFT TEMPS AS IS FOR NOW...AS A DECREASE OF CLOUDS WILL ALLOW TEMPS TO WARM BACK INTO THE 80S. && .AVIATION... /12Z ISSUANCE/ THOUGH TIMING IT IS A TRICKY PROSPECT...IT APPEARS PRETTY LIKELY THAT SHRA/TSRA WILL IMPACT BOTH TERMINALS AT SOME POINT TODAY. FIRST WAVE WILL PROBABLY MISS BOTH SITES...BUT MIGHT GET CLOSE TO KMSL SO WILL START OFF THE TAF WITH VCSH. FCST BRINGS IN SHRA PREVAILING AROUND MIDDAY WITH VCTS AND CB...WITH A 4-HR TEMPO FOR MVFR VISBY AND CIGS DURING THE AFTN. STRAY SHRA/TSRA CANNOT BE RULED OUT AFTER MID-AFTN...BUT THAT IS TOO TOUGH TO TIME THIS FAR OUT...AND WILL JUST INCLUDE A CB MENTION. SKIES SHOULD BEGIN TO CLEAR AROUND SUNSET...AND WITH LIGHT WINDS...THAT SHOULD SET THE STAGE FOR PREVAILING MVFR VISBY AT BOTH SITES AFTER MIDNIGHT. WILL INCLUDE IFR VISBY AT KMSL BASED ON USUAL CLIMATOLOGICAL TRENDS. && .PREV DISCUSSION... /ISSUED 338 AM CDT TUE JUL 13 2010/ SHORT TERM...THROUGH THURSDAY... CONDITIONS ARE QUIET AND SKIES ACTUALLY MOSTLY CLEAR ACROSS THE CENTRAL TENN VALLEY THIS MORNING. FOR MUCH OF YESTERDAY AND NOW TODAY...CONVECTION HAS SEEMED VERY CONTENT TO REMAIN BURIED IN WSWLY FLOW JUST ACROSS THE BORDER IN WRN/MID TN. THERE IS A WEAK W-E ORIENTED CONVERGENCE AXIS FROM NW AL INTO THE CAROLINAS...BUT SFC ANALYSIS IS OTHERWISE UNREMARKABLE. A FAIRLY ROBUST TROUGH--THE MAIN PLAYER IN THE 1ST 24 HRS OF THE FCST--EXTENDS FROM THE LWR GRT LKS BACK INTO THE RED RIVER VALLEY. IT IS TOUGH TO BE TOO OPTIMISTIC ABOUT RAIN CHANCES TODAY GIVEN HOW SPARSE THE ACTIVITY HAS BEEN TO THIS POINT AND HOW CONCENTRATED IT HAS BEEN JUST TO THE NORTH. DESPITE THE TROUGH POISED TO SWING THRU THE AREA LATE TODAY AND THE EXPECTED MOISTURE AVAILABILITY...GFS MOS POPS ARE SURPRISINGLY LOW /ONLY AROUND 60 PCT/. EVEN THE TYPICALLY- WET LOCAL WRF IS RELATIVELY DRY FOR TODAY. GIVEN THESE FACTORS AND UNIMPRESSIVE MOISTURE TRANSPORT...WILL GO NO HIGHER THAN THAT GFS MOS FOR POPS...TAPERING TO CATEGORICAL POPS ACROSS SRN MID TN AND CHANCE POPS S AND E OF HSV. WILL STICK CLOSE TO MOS CONSENSUS FOR HIGHS AS WELL IN ANTICIPATION OF DECENT SUNSHINE. THIS LIKELY MEANS A MORE UNSTABLE ENVIRONMENT COINCIDENT WITH STILL-DECENT DEEP LAYER SHEAR. SPC DAY 1 OUTLOOKS THE AREA IN A SLT RISK FOR MAINLY WIND DMG WHICH APPEARS QUITE REASONABLE. THE TROUGH SHOULD BE CROSSING THE AREA LATE AFTN/EARLY EVENING SO CONVECTION WILL LINGER INTO THE EVENING HRS...BEFORE MOSTLY DISSIPATING/EXITING THE CWFA. THE MIDDLE OF THE WEEK WILL BE A RETURN TO THE HEAT AS THE 596+ DAM HIGH ROLLS EWD...ENDING UP CENTERED OVER THE MID-SOUTH THURSDAY. STILL COULD SEE A FEW SHRA/TSRA WEDNESDAY AMIDST THE N/NW FLOW...BUT HOT CONDITIONS WILL STILL BE THE RULE WITH HIGHS AT LEAST IN THE MID 90S. MORE SUBSTANTIAL SUBSIDENCE WILL SET UP THURSDAY UNDER THE HIGH. SOUNDINGS INDICATE ENOUGH OF AN INVERSION TO REMOVE POPS FROM THE FCST...AND MOS CONSENSUS CONSISTENTLY BRINGS HIGHS INTO THE UPR 90S. UNFORTUNATELY...THE LOWER LEVELS WILL STILL BE QUITE MOIST DURING THIS TIME FRAME...SO EVEN DIURNAL MIXING WILL NOT LOWER THE HIGH DEWPOINTS BY MUCH. HEAT INDICES LOOK MARGINAL ATTM FOR A HEAT ADVISORY WEDNESDAY...BUT CONFIDENCE IS HIGHER FOR THURSDAY. FEEL IT IS TOO EARLY TO ISSUE AN ADVY ATTM...BUT WILL BEGIN TO ADDRESS THE HEAT SITUATION IN THE MORNING HWO. LONG TERM...FRIDAY THROUGH MONDAY... THE WORST OF THE HEAT WILL NOT LAST LONG...AS A POTENT UPPER LOW OVER ONTARIO DROPS A SHORTWAVE INTO THE MID-MS VALLEY...CAUSING THE RIDGE TO ERODE AND RETROGRADE INTO THE SRN PLAINS. SCTD SHRA/TSRA SHOULD RETURN FRIDAY-SATURDAY AS THE TROUGH AXIS PIVOTS THROUGH THE AREA...AND WHILE IT WILL NOT EXACTLY FEEL COOL...HIGH TEMPS WILL RETREAT BACK INTO THE LOWER-MID 90S. HOWEVER...DESPITE A DIVERGENCE IN MODEL SOLNS...THERE IS GOOD AGREEMENT THAT RIDGING WILL BUILD BACK INTO THE AREA EARLY NEXT WEEK. && .HUN WATCHES/WARNINGS/ADVISORIES... AL...NONE.
