NWS Huntsville, AL wrote its last area forecast discussion before the first event at Jun 20, 2:38 PM CST, 2 hours 29 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE HUNTSVILLE AL 338 PM CDT THU JUN 20 2013 .DISCUSSION... SHORT TERM: WATER VAPOR SATELLITE DATA AND UPPER AIR ANALYSES CONTINUE TO INDICATE THE PRESENCE OF A STRENGTHENING MID-TROPOSPHERIC HIGH ACROSS THE SOUTHERN/CENTRAL PLAINS THIS AFTERNOON...DOWNSTREAM FROM A STATIONARY UPPER LOW ACROSS WASHINGTON/OREGON. TO THE EAST OF THE RIDGE...A WEAKER MID-LEVEL VORT MAX WILL CONTINUE TO SHIFT EAST- SOUTHEASTWARD THROUGH THE LOWER OHIO/UPPER TENNESSEE VALLEYS THIS AFTERNOON...AND THIS HAS LIKELY PROVIDED THE NECESSARY FORCING FOR THE DEVELOPMENT OF SCATTERED THUNDERSTORMS FROM WESTERN KENTUCKY SOUTHWESTWARD INTO SOUTHWEST NORTH CAROLINA. THE MID-LEVEL WAVE IS PROGGED TO WEAKEN CONSIDERABLY AS IT DROPS SOUTHWARD ACROSS THE AREA TONIGHT IN NORTHERLY FLOW REGIME EAST OF THE CENTRAL PLAINS MID- LEVEL HIGH. HOWEVER...MOST NWP GUIDANCE INDICATES THAT NORTHWEST FLOW IN THE 700-500 MB LAYER WILL INCREASE TO 15-20 KNOTS AS THE WAVE PASSES...AND THIS MAY ALLOW RESIDUAL AFTERNOON CONVECTION TO MOVE SOUTHEASTWARD INTO THE REGION FROM MIDDLE TENNESSEE. ALTHOUGH THE COVERAGE OF STORMS MAY BE A BIT HIGHER IF A COLD POOL CAN ORGANIZE AND SEND A STRONG OUTFLOW BOUNDARY SOUTHWARD...WILL ONLY MAKE A MINOR UPWARD ADJUSTMENT TO POPS FOR THE SOUTHERN MIDDLE TENNESSEE AND NORTHEAST ALABAMA COUNTIES. AS IS TYPICALLY THE CASE DURING THE SUMMER...GUSTY WINDS, LIGHTNING, AND LOCALLY HEAVY RAINFALL WILL OCCUR WITH THE STRONGEST CELLS...BUT ANY ACTIVITY WILL DIMINISH RAPIDLY BY 21/03Z. DURING THE REMAINDER OF THE SHORT TERM PERIOD...A WEAK UPPER LOW IS FORECAST TO BECOME ESTABLISHED ACROSS GEORGIA/SOUTH CAROLINA BY FRIDAY MORNING. THIS FEATURE IS EXPECTED TO SLOWLY RETROGRADE ACROSS THE AREA BY SATURDAY/SATURDAY NIGHT...WHILE GRADUALLY EVOLVING FROM AN INVERTED TROUGH INTO A BROAD WEAKNESS IN THE SUBTROPICAL RIDGE. WILL MAINTAIN A SLIGHT CHANCE POP FOR THE ENTIRE FORECAST AREA TOMORROW...AS MID-LEVEL FLOW VEERS TO NORTHEAST -- POTENTIALLY ALLOWING ANY CONVECTION THAT FORMS ALONG THE HIGHER TERRAIN OF EAST TENNESSEE TO DRIFT SOUTHWESTWARD INTO THE AREA. OTHERWISE...WILL ONLY KEEP A SILENT 10 POP IN PLACE FROM FRIDAY NIGHT-SATURDAY NIGHT...AS WEAK FORCING SHOULD RESULT IN LITTLE THREAT FOR CONVECTION DURING THIS PERIOD. HOWEVER...LOW-LEVEL SOUTHEASTERLY FLOW WILL BEGIN TO INCREASE BY SATURDAY NIGHT AS THE INVERTED TROUGH SHIFTS TO THE WEST OF THE AREA...AND THIS WILL ALLOW DEEPER MOISTURE/CLOUD COVER TO ARRIVE BY SUNDAY MORNING. 70/DD LONG TERM: THE WEAK LOW OVER THE SOUTHEAST WILL EVENTUALLY DRIFT NORTHWARD AND GET REABSORBED INTO THE FLOW EARLY IN THE WEEK, BUT SOME AMOUNT OF WEAK TROUGHING WILL PERSIST OVER THE EASTERN CONUS THROUGH TUESDAY AND EARLY WEDNESDAY. SO BOTH THE GFS AND ECMWF MOS POPS CONTINUE WITH A 20 AT NIGHT, 30 DURING THE DAY, AND THESE VALUES STILL SEEM REASONABLE IN LIGHT OF THE EXPECTED PATTERN. MEDIUM-RANGE MODELS ARE IN AGREEMENT ABOUT A FAIRLY ROBUST SHORTWAVE TROUGH SWINGING ACROSS THE NORTHERN AND NORTHEASTERN CONUS LATE IN THE FORECAST PERIOD. THERE WAS DISAGREEMENT ON DEPTH AND TIMING, BUT 12Z RUNS AND NORTH AMERICAN ENSEMBLES INDICATE GROWING CONSENSUS THAT A FAIRLY LARGE, LONGWAVE TROUGH WILL BE CARVED OUT OVER THE EASTERN CONUS THURSDAY INTO FRIDAY. BASED UPON THIS SOLUTION, DECIDED TO GO WITH A SOMEWHAT WETTER FORECAST WEDNESDAY AND THURSDAY. IF THE TROUGH IS AS ROBUST AS INDICATED, THESE POPS WILL NEED TO BE RAISED FURTHER AND TEMPERATURES WILL NEED TO BE LOWERED. GFS AND ECMWF MOS TEMPERATURES THROUGH THE EXTENDED ARE STRONGLY CLIMO-BASED, AND THIS STILL LOOKS REASONABLE.
