131 FXUS64 KMRX 170543 AFDMRX Area Forecast Discussion National Weather Service Morristown TN 1243 AM EST Tue Jan 17 2017 .AVIATION... VFR conditions currently across the terminals. Southerly winds ahead of an approaching cold front should keep fog from forming tonight. These winds will have a downsloping component and expect VFR conditions will continue during the overnight hours with a small chance for MVFR ceilings at KCHA near sunrise. Current radar imagery indicates widespread showers and a few thunderstorms across Western and Middle Tennessee. The main aviation challenge will be the timing of the precip. For now, it appears that showers will move in around daybreak and persist throughout much of the day. Instability values will increase enough by 20-22z for a few thunderstorms and have mentioned VCTS in the TAFs. Southerly winds will increase after 15z with some gusts into the 20 kt range. && .MRX WATCHES/WARNINGS/ADVISORIES... NC...None. TN...None. VA...None. && $$ MA
