NWS Morristown, TN wrote its last area forecast discussion before the first event at Sep 26, 12:37 PM EST, 38 minutes earlier.
Area Forecast Discussion National Weather Service Morristown TN 137 PM EDT MON SEP 26 2016 .AVIATION... Shower and thunderstorm chances continue to be likely at all TAF sites this afternoon as a cold front pushes through the area. Sped up timing from previous forecast by a few hours. Best window for precip and convection at CHA and TYS will be from 18z through 22Z and 19Z to 23Z at TRI. During this time VFR conditions are expected for the majority but brief MVFR can't be ruled out with any passing thunderstorm. Later tonight, cigs come down due to residual low-level moisture behind the front and will result in MVFR conditions for all sites. Cigs will gradually lift to VFR later tomorrow morning as mixing ensues. && .MRX WATCHES/WARNINGS/ADVISORIES... NC...None. TN...None. VA...None. && SR
