Area forecast discussion, May 23, 3:08 AM CDT, 1 hour 54 minutes before
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NASHVILLE TN 308 AM CDT FRI MAY 23 2014 .DISCUSSION....THE FRONT RESPONSIBLE FOR SCATTERED THUNDERSTORMS OVER OUR NORTHERN COUNTIES THURSDAY AFTERNOON THROUGH THIS MORNING WAS LOCATED JUST SOUTH OF THE KY STATE LINE. THIS FRONT WILL CONTINUE TO PUSH SLOWLY SOUTHWARD TODAY WITH A 20-30 PERCENT CHANCE FOR THUNDERSTORMS ACROSS THE AREA. THERE WILL BE SOME POTENTIAL FOR STRONG TO BRIEFLY SEVERE STORMS TODAY...MAINLY ALONG AND SOUTH OF I-40. ALTHOUGH THE SEVERE POTENTIAL APPEARS A LITTLE LESS THAN YESTERDAY...FORECAST SOUNDINGS SHOW CAPES GREATER THAN 2 KJ/KG ON THE SOUTH SIDE OF THE BOUNDARY THIS AFTERNOON. DAMAGING WIND GUSTS WILL BE THE MAIN CONCERN. A FEW STORMS MAY LINGER INTO THE EVENING OVER OUR SOUTHWEST COUNTIES. OTHERWISE...SLIGHTLY COOLER AND DRIER AIR WILL BE PUSHING IN FROM THE NNE TONIGHT. SATURDAY WILL PROBABLY BE THE NICEST DAY OF THIS FORECAST PERIOD. SURFACE HIGH PRESSURE OVER THE GREAT LAKES WILL EXTEND DOWN INTO TN WITH SEASONABLY WARM TEMPERATURES AND TOLERABLE HUMIDITY LEVELS. WE CANNOT RULE OUT AN ISOLATED THUNDERSTORM OVER OUR SOUTHWEST COUNTIES WHERE MOISTURE WILL BE A LITTLE GREATER. FOR SUNDAY INTO MEMORIAL DAY...TEMPS WILL WARM AGAIN AS THE COOL SURFACE HIGH PRESSURE LIFTS AWAY AND UPPER HEIGHTS RISE. THERE WILL BE A SMALL CHANCE FOR THUNDERSTORMS EACH DAY AS MOISTURE AND INSTABILITY GRADUALLY INCREASES. TEMPS WILL PUSH WELL INTO THE 80S...PERHAPS REACHING THE FIRST 90 OF THE YEAR FOR SOME LOCATIONS. IN THE EXTENDED FORECAST...MODELS SHOW MAJOR DIFFERENCES. THE ECMWF BRINGS A CUTOFF LOW SLOWLY EASTWARD FROM THE PLAINS STATES TO THE MID SOUTH THROUGH THE WEEK...RESULTING IN UNSETTLED AND POSSIBLY VERY WET CONDITIONS. THE GEFS POINTS TO A GREATER INFLUENCE FROM A NORTHEAST TROUGH AND AN ASSOCIATED BACKDOOR COLD FRONT. THIS SCENARIO WOULD BRING A SHOT OF COOLER AND DRY WX MID TO LATE WEEK. GIVEN THE UNCERTAINTIES...INCLUDING VARIABILITY WITHIN EACH MODEL ENSEMBLE SUITE...WE WILL CONTINUE TO USE AN ALL MODEL BLEND YIELDING GRADUALLY LOWERING TEMPS AND PERSISTENT LOW POPS. 13 && .PRELIMINARY POINT TEMPS/POPS...
