.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.
