Area Forecast Discussion National Weather Service Nashville TN 719 PM CDT Sat Apr 29 2017 .DISCUSSION... Have continued low pops through the evening hours for eastern areas, as mainly isolated convection continues. Believe loss of daytime heating should be the death knell for these few storms over the next few hours. && .AVIATION... 00Z TAF DISCUSSION. Looking at VFR conditions through the TAF period, with some wind shear overnight, strong southerly winds tomorrow, and chances for showers and thunderstorms moving in from west to east from mid afternoon through the overnight hours. Winds will calm down slightly overnight but still be around 10 knots gusting to 20 knots. Wind shear will move into the forecast during this time with a strong low level jet around 2kft off the surface around 40 to 45 knots. Just after sunrise, winds will pick up to be sustained around 15 to 20 knots with gusts over 30 knots by the late morning/afternoon. Chances for showers and thunderstorms will first impact KCKV after 21Z Sunday, and likely after 00Z for KBNA. Therefore just have shra and vcts for KCKV after 21Z for now. && .PRELIMINARY POINT TEMPS/POPS...
