NWS Huntsville, AL wrote its last area forecast discussion before the first event at Jun 23, 8:16 PM CST, 3 hours 14 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED NATIONAL WEATHER SERVICE HUNTSVILLE AL 916 PM CDT TUE JUN 23 2015 .UPDATE... INCREASED RAIN CHANCES FOR THE LATE EVENING...ALONG WITH MINOR TEMP...DEWPOINT...AND CLOUD COVER TWEAKS. && .DISCUSSION... AFTER ANOTHER HOT/HUMID DAY ACROSS THE TENNESSEE VALLEY...THERE IS A CHANCE THAT SOME OF THE AREA COULD RECEIVE SHOWERS LATER THIS EVENING...AS A CLUSTERS OF CONVECTION NOW AFFECTING PARTS OF WESTERN AND MIDDLE TENNESSEE APPROACHES. EARLIER...HIGH TEMPERATURES ACROSS THE AREA WERE AS HIGH AS 98 AT MUSCLE SHOALS AND HUNTSVILLE. SLIGHTLY HIGHER MOISTURE VALUES OVER NW ALABAMA ENABLED HEAT INDICES TO REACH 105 FOR A COUPLE HOURS AT THE MUSCLE SHOALS AIRPORT...PRODUCING HEAT ADVISORY CONDITIONS. FROM CHECKING A FEW OBSERVATIONS AROUND THE REGION...A FEW OTHER SITES WEST OF I65 CAME CLOSE TO 105 HEAT INDICES ALSO. SLIGHTLY COOLER TEMPERATURES WERE NOTED FOR OUR CENTRAL AND EASTERN AREAS...BUT WITH HIGHS STILL IN THE LOW/MID 90S. BEFORE THE HEAT RETURNS TOMORROW...A CLUSTER OF SHOWERS AND THUNDERSTORMS TRACKING TO THE SE 10-15 MPH OVER WEST/MIDDLE TENNESSEE APPROACHES THE FORECAST AREA. A FEW SHOWERS AND STORMS HAVE ALREADY AFFECTED PARTS OF OUR SOUTHERN MIDDLE TENNESSEE COUNTIES AND A FEW PLACES IN ALABAMA NORTH OF THE TENNESSEE RIVER. MODEL OUTPUT FROM THE RAP AND HRRR BOTH INDICATE THAT THE MID-TN ACTIVITY...SHOULD IT HOLD TOGETHER...WILL BEGIN AFFECTING THE AREA LATER THIS EVENING... SAY IN THE NEXT 1 TO 2 HOURS. THE NEW NAM WAS NOT AS WET...SUGGESTING THE SYSTEM SHOULD FADE AS IT REACHES THE FORECAST AREA. MAIN IMPACTS FROM THIS SYSTEM (FROM CURRENT RADAR TRENDS) SHOULD IT MAINTAIN INTENSITY ARE WIND GUSTS TO 50 MPH...SMALL HAIL...FREQUENT LIGHTNING...AND LOCALLY HEAVY RAIN. THE MODELS WERE IN GENERALLY GOOD AGREEMENT ENDING THE ACTIVITY AFTER MIDNIGHT...AS IT PUSHES FURTHER SOUTHWARD AND/OR DISSIPATES. ONLY MADE MINOR TWEAKS TO TEMP/DEWPOINT/SKY GRIDS FOR THE OVERNIGHT...MAINLY AN UPDATE TO CURRENT TRENDS. TEMP TRENDS WERE MAINLY DOWN A DEGREE OR TWO IN SOME SPOTS. FROM NEW DATA COMING IN...SEE LITTLE REASON TO CHANGE ON-GOING THINKING ON A WIDER AREAL COVERAGE OF HEAT ADVISORY CONDITIONS ON WED. RESIDUAL MOISTURE FROM ANY RAIN THAT OCCURS TONIGHT...WILL CERTAIN HELP IN THIS DEPARTMENT TOMORROW. RSB && .AVIATION... /ISSUED 635 PM CDT TUE JUN 23 2015/ FOR 00Z TAFS...WILL CONTINUE WITH VFR CONDITIONS THROUGH THE FORECAST PERIOD FOR HSV AND MSL. ISOLATED SHRA/TSRA TRYING TO SLOWLY DEVELOP ACROSS THE AREA...BUT AM NOT CONFIDENT ENOUGH AT THIS TIME TO ADD SHRA/TSRA MENTION TO THE FORECAST FOR HSV AND MSL. TT && .PREV DISCUSSION... /ISSUED 345 PM CDT TUE JUN 23 2015/ LOW PRESSURE SYSTEM MOVING OUT OF THE GREAT LAKES REGION AND INTO THE NE US HAS A WEAK COLD FRONT EXTENDING SW THROUGH THE OH VALLEY AND INTO THE CENTRAL PLAINS STATES. OUT AHEAD OF THIS...MULTIPLE OUTFLOW BOUNDARIES WERE NOTED ON VIS SATELLITE AND RADAR IMAGERY TODAY FROM THE MCS THAT MOVED THROUGH IL YESTERDAY. THE NAM AND HIRES ARW/NMM MODELS DEVELOP SHOWERS/THUNDERSTORMS OVER THE MO/IL/KY AREA THIS AFTERNOON AND DROP THEM S/SE INTO THE TN VALLEY THIS EVENING WITH ACTIVITY TAPERING OFF AFTER MIDNIGHT. THE MAIN THREAT WITH ANY STORMS THAT FORM WILL BE WIND GUSTS AROUND 40 MPH...HEAVY RAIN AND FREQUENT LIGHTNING. THE MAIN STORY CONTINUES TO BE THE HOT TEMPERATURES AND HEAT INDEX VALUES EXPECTED OVER THE NEXT TWO DAYS. GUIDANCE HAS BEEN FLUCTUATING BACK AND FORTH ON WHICH DAY WILL BE THE HOTTEST...WEDNESDAY OR THURSDAY. TEMPS THE PAST FEW DAYS HAVE BEEN FAIRLY CONSISTENT AND TOPPING OUT AROUND 98 DEGREES. THIS WILL BE THE CASE FOR WEDNESDAY/THURSDAY AND COULD SEE TEMPS A DEGREE WARMER WITH THE ADVERTISED HIGH PRESSURE SYSTEM CENTERED OVER THE AREA BOTH WEDNESDAY AND THURSDAY. THE ONLY CONCERN WILL BE THE DEWPOINT TEMPERATURES AND WHETHER OR NOT THEY MIX DOWN BELOW 70 DEGREES DURING THE AFTERNOON HOURS. OVER THE WEEKEND WE HAD MORE DRY AIR ALOFT AND WITH THE HOT TEMPERATURES WE WERE ABLE TO MIX DOWN SOME OF THIS DRIER AIR DOWN TO THE SURFACE WHICH KEPT HEAT INDICES BELOW CRITERIA. FORECAST SOUNDINGS KEEP PWAT VALUES AROUND 1.7 TO 1.8 INCHES WED/THUR AND WITH THE HIGH OVER HEAD THERE IS LITTLE IN THE WAY OF DRY AIR ADVECTION TO DECREASE THESE VALUES ANY. AS WITH TODAY THE MOISTURE FROM DECAYING MCSS OVER THE MIDWEST SHOULD HELP TO KEEP HIGHER DEWPOINTS AROUND. SO...THE NEXT TWO DAYS WILL LIKELY FOLLOW A SIMILAR TREND AS TODAY WITH DEWPOINTS HOLDING IN THE LOWER 70S AND TEMPS IN THE UPPER 90S TO NEAR 100 DEGREES. THIS WILL ALLOW FOR HEAT INDICES TO REACH ABOVE 105 DEGREES FOR NORTH CENTRAL AND NORTHWESTERN ALABAMA ON WEDNESDAY AND HAVE ISSUED A HEAT ADVISORY BASED ON THESE VALUES. GUIDANCE HAS COME IN WARMER FOR THURSDAY WITH TEMPS IN THE MID TO UPPER 90S AND DEWPOINTS IN THE LOWER 70S. BELIEVE THAT WE COULD REACH HEAT ADVISORY CRITERIA AGAIN ON THURSDAY BUT WITH SOME GUIDANCE SHOWING INCREASED CLOUD COVER AND A FEW SHOWERS DEVELOPING EARLY AFTERNOON...THERE IS ENOUGH UNCERTAINTY TO HOLD OFF. THE HIGH PRESSURE SYSTEM DISSIPATES AND SHIFTS EAST THURSDAY INTO FRIDAY WHILE A LOW PRESSURE SYSTEM AND UPPER LEVEL TROUGH DROPS SE OUT OF THE NORTHERN PLAINS TOWARDS THE TN VALLEY. THIS SYSTEM WILL BRING SOME MUCH NEEDED RELIEF FROM THE HEAT AND SOME WELCOMED RAIN. THE FORCING ASSOCIATED WITH THE FRONT AND THE UPPER LEVEL SYSTEM SHOULD ALLOW FOR MORE WIDESPREAD SHOWERS/THUNDERSTORMS TO FORM ON FRIDAY. SHEAR INCREASES ON SATURDAY AS THE FRONT NEARS THE AREA AND WE COULD SEE MORE ORGANIZED STORMS DEVELOP ON SATURDAY WITH A FEW POTENTIALLY STRONG THUNDERSTORMS. HIGH TEMPERATURES ON FRIDAY WILL RETURN TO NORMAL WITH VALUES NEAR 90 AND THEN DROP INTO THE LOW TO MID 80S ON SATURDAY. THE GFS AND ECMWF DIFFER IN THE TIMING OF WHEN THE FRONT MOVES THROUGH THE AREA...BUT IT SHOULD BE SOUTH AND EAST BY SUNDAY. WE WILL REMAIN IN NORTHERLY/NORTHWESTERLY FLOW INTO EARLY NEXT WEEK WHICH WILL KEEP TEMPS BELOW NORMAL IN THE MID 80S. STUMPF && .HUN WATCHES/WARNINGS/ADVISORIES...
