NWS Huntsville, AL wrote its last area forecast discussion before the first event at Aug 8, 1:32 PM CST, 1 hour 42 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE HUNTSVILLE AL 232 PM CDT FRI AUG 8 2014 .DISCUSSION... THE 19Z SURFACE ANALYSIS...88-D RETURNS AND IR/VISIBLE SATELLITE IMAGERY ALL INDICATE THAT A WEAK FRONTAL BOUNDARY WAS EXTENDING SOUTHEAST OUT OF MIDDLE TENNESSEE INTO NORTHEAST ALABAMA AND INTO WEST CENTRAL GEORGIA. A VORT MAX AT 500 MILLIBARS WAS ANALYZED TO BE MOVING SOUTHEAST OUT OF ARKANSAS AND INTO WEST TENNESSEE. THIS FEATURE WILL MOVE SOUTHEAST TOWARD THE FORECAST AREA THROUGH THIS EVENING. WITH THE FORECAST AREA REMAINING SOUTHWEST OF THE FRONTAL BOUNDARY...A MORE MOIST AND UNSTABLE ATMOSPHERE IS OVER THE AREA. HOURLY LAPS/MSAS LIS WERE AROUND -4 AND PWAT VALUES APPROACHING TWO INCHES ACROSS THE AREA AS OF 19Z. WE WILL CONTINUE TO MONITOR WET MICROBURST POTENTIAL THROUGH EARLY EVENING. HAVE CONTINUED WITH INCREASING POPS FOR TONIGHT AND INTO SATURDAY. THE SECOND 500 MILLIBAR VORT MAX WILL DROP SOUTHEAST OUT OF MISSOURI INTO WEST TENNESSEE BY 12Z SATURDAY. THIS WILL BE THE FOCUSING MECHANISM FOR MORE SHRA/TSRA DEVELOPMENT FOR SATURDAY. WITH PWAT VALUES EXPECTED TO BE SLIGHTLY ABOVE TWO INCHES...EXPECT THAT THERE WILL BE A DECENT POTENTIAL FOR HEAVY RAINFALL ACROSS THE FORECAST AREA. WILL CONTINUE WITH LIKELY POPS FORECAST AREA WIDE. THERE SHOULD BE A LULL IN THE SHRA/TSRA ACTIVITY INITIALLY BY SUNDAY...BUT WILL CONTINUE TO KEEP IN A LOW CHANCE POP FOR THE FORECAST AREA. IN THE SHORT TERM...HAVE SLIGHTLY BUMPED UP TEMPS TO BE MORE IN LINE WITH GUIDANCE NUMBERS. A COLD FRONT WILL TAKE SHAPE OVER THE UPPER PLAINS STATES BY SUNDAY...AND IS PROGGED BY THE MODELS TO SHIFT SOUTHEAST INTO THE LOWER OHIO VALLEY TO NEAR THE OHIO RIVER BY 18Z MONDAY. THE MODELS ARE IN FAIR AGREEMENT INVOLVING MOVING THE COLD FRONT FURTHER SOUTHEAST INTO SOUTHERN MIDDLE TENNESSEE BY 06Z TUESDAY AND SLOWLY THROUGH THE FORECAST AREA BY 00Z WEDNESDAY. HAVE SLIGHTLY UPPED PRECIP CHANCES FOR MONDAY NIGHT AND INTO TUESDAY FOR THE FORECAST AREA. WILL CONTINUE WITH LINGERING SLIGHT CHANCE POPS FOR TUESDAY NIGHT AND INTO WEDNESDAY...TO ACCOUNT FOR THE SLOW MOVEMENT SOUTHEAST OF THE COLD FRONT AND THE UNCERTAINTY THAT THE FRONT WILL NOT MOVE NEARLY AS FAST AS THE MODELS ARE INDICATING. HAVE BACKED OFF SLIGHTLY ON HIGH TEMPS ON WEDNESDAY...WITH SOME COOL ADVECTION OCCURRING IN THE WAKE OF THE COLD FRONT. HAVE REMOVED ANY PRECIP CHANCES FOR THE FORECAST AREA AFTER WEDNESDAY...AS HIGH PRESSURE WILL BUILD SOUTHEAST INTO THE REGION THROUGH THURSDAY AND INTO FRIDAY. COOLER AIR FILTERING INTO THE FORECAST AREA BY WEDNESDAY THROUGH THURSDAY SHOULD AGAIN RESULT IN TEMPS BEING SLIGHTLY BELOW NORMAL FOR MID AUGUST. HAVE LOWERED TEMPS NEARLY A CATEGORY FOR THURSDAY HIGHS AND LOWS AND INTO FRIDAY MORNING...WHICH WOULD BE MORE IN LINE WITH THE ECMWF TEMP GUIDANCE. TT && .AVIATION... /ISSUED 1259 PM CDT FRI AUG 8 2014/ FOR 18Z TAFS...PRIMARY CONCERN FOR BOTH HSV/MSL DURING THE UPCOMING 24-HR PERIOD WILL BE TSRA...WITH MULTIPLE OPPORTUNITIES FOR CONVECTION THIS TAF CYCLE. SHRA/TSRA CURRENTLY DEVELOPING ACROSS NRN ALABAMA WILL INCREASE IN COVERAGE THRU THE AFTN...WITH MORE WIDESPREAD AND SIGNIFICANT IMPACTS COMING BTWN 08/20-23Z AS A MORE ORGANIZED LINE OF STORMS CURRENTLY OVER NRN MISSISSIPPI SWEEPS ACROSS REGION FROM THE WEST. THIS ACTIVITY WILL MOVE EWD EARLY THIS EVENING...LEAVING A DECK OF LOWER STRATUS CLOUDS IN ITS WAKE. ANOTHER DISTURBANCE WILL LIKELY IMPACT THE REGION BEGINNING VERY LATE TONIGHT/EARLY SATURDAY MORNING...AND HAVE REINTRODUCED VCTS/CB BTWN 09/05-12Z. A THIRD AND POTENTIALLY STRONGER DISTURBANCE WILL BEGIN TO IMPACT NW ALABAMA LATE IN THE PERIOD...AND HAVE INCLUDED A SEPARATE VCTS/CB GROUP FOR MSL BEGINNING AT 09/16Z. OUTSIDE OF PRECIP VFR CONDS ARE EXPECTED...BUT BRIEF DROPS TO IFR CIG/VLIFR VSBY WILL BE PSBL IN SHRA/TSRA.
