NWS Nashville, TN wrote its last area forecast discussion before the first event at Sep 11, 11:48 AM CST, 37 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE NASHVILLE TN 1248 PM CDT FRI SEP 11 2015 .UPDATE... FOR 18Z AVIATION. && .DISCUSSION... THIS MORNING'S UPDATE REVOLVES AROUND THE APPROACHING COLD FRONT AND THE TIMING OF PRECIPITATION THAT WILL ACCOMPANY IT. SUBSIDENCE AT THE SURFACE IS ALREADY PLAYING A ROLE IN KILLING OFF PRE-FRONTAL ACTIVITY. A FEW SHOWERS/THUNDERSTORMS THAT DEVELOPED OVER WEST TN HAVE DIED OFF BEFORE REACHING OUR WESTERN COUNTIES. THIS SHOULD CONTINUE TO BE THE CASE FOR THE NEXT COUPLE OF HOURS UNTIL THE WEAK SURFACE RIDGE CAN BE CLEARED OUT OF THE WAY AND MORE OF THE SYNOPTIC EFFECTS OF THE UPPER LEVEL TROUGH CAN BE EXPERIENCED. IN ADDITION TO THE UPPER LEVEL HELP...AN OUTFLOW BOUNDARY FROM OVERNIGHT CONVECTION UPSTREAM...AS WELL AS THE ARRIVAL OF THE SURFACE FRONT...WILL HELP TO SPARK SOME CONVECTION THIS AFTERNOON ACROSS THE MID-STATE. WHILE I'M STILL NOT CRAZY ABOUT ANY SEVERE WEATHER BECAUSE OF THE EXTREMELY WEAK WIND FIELDS...THE FOCUSING MECHANISM OF THE OUTFLOW BOUNDARY ACROSS THE EAST AND THE FRONT BREAKING INTO THE WEST THIS MORNING COULD HELP A COUPLE OF THESE STORMS BECOME STRONG LATER THIS AFTERNOON. STRONG GUSTY WINDS WOULD BE THE GREATEST CONCERN. HAVE GIVEN LATEST TIMING THINKING FOR THE BULK OF TODAY'S RAIN IN THE GRIDS...AND DON'T FORGET ABOUT THE WRAP AROUND ACTIVITY SATURDAY DUE TO THIS SHARP UPPER LEVEL TROUGH THAT WILL DIVE INTO THE TENNESSEE VALLEY LATER SATURDAY MORNING. THE SHARPNESS OF THIS SHORTWAVE AND ASSOCIATED VORT MAX COULD ALSO BRING A COUPLE OF RUMBLES OF THUNDER THROUGH NOON...AND POPS WILL LIKELY REMAIN IN THE FORECAST INTO SATURDAY EVENING. UPDATES ALREADY OUT. UNGER && .AVIATION... 18Z TAF DISCUSSION. ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS ARE STARTING TO DEVELOP ACROSS WESTERN PORTIONS OF THE MID-STATE. WILL COVER WITH TEMPOS AS CONVECTION SHOULD BE FAIRLY SHORT LIVED IN ANY ONE AREA. BRIEF WIND GUSTS AND REDUCTION IN VIS ARE ALSO POSSIBLE WITH SOME OF THE HEAVIER STORMS AS THEY MOVE EASTWARD. KCSV WILL LIKELY SEE A MAJORITY OF THE ACTION LATER THIS AFTERNOON AND EARLY THIS EVENING. WINDS WILL CONTINUE TO SHIFT AROUND TO THE NORTHWEST THROUGH THE AFTERNOON AS THE FRONT MOVES THROUGH THE STATE. NO SIGNIFICANT WINDS ARE EXPECTED OUTSIDE OF THUNDERSTORMS. CIGS WILL BEGIN TO DROP OFF AFTER 00Z THIS EVENING WITH EVERYBODY EXPECTED TO REACH IFR TO LIFR AFTER MIDNIGHT. SOME IMPROVEMENT IS EXPECTED TOWARD THE END OF THIS TAF CYCLE...BUT WRAP AROUND MOISTURE WILL KEEP AT LEAST MVFR CIGS AND EVEN A CHANCE OF SCATTERED SHOWERS AND THUNDERSTORMS IN THE FORECAST THROUGH AT LEAST 00Z SUNDAY. UNGER && .OHX WATCHES/WARNINGS/ADVISORIES... NONE. &&
