we are monitoring convective trends in Tennessee along an east-west boundary. Cold
pools continue to generate and redevelop thunderstorms a bit further S with
time. These are thriving on a high precipitable water (~1.9inch) and moderate cape
(1500-2500 j/kg) environment. The ohx hodograph is rather linear with
a deep west-southwest-east-northeast flow through low to middle levels and west-east through high levels
of the tropopause. This is allowing for training of storms to occur with
very heavy rainfall. The latest rap solution suggests a gradual southerly
progression of the mesoscale convective system clusters into our southern Tennessee and northern Alabama counties.
We have gone with "good chc" probability of precipitation in southern Tennessee into northwestern al, and lower
chance probability of precipitation further S of the Tennessee River. Dew points have risen back into
the l-m70s this evening. This along with thickening middle-high level
cloud cover from thunderstorms will keep temperatures a bit warmer than earlier
forecast as well.

for 06z tafs... scattered rain showers and possibly a thunderstorms and rain will remain possible
over the next few hours. VFR conditions should prevail until areas of
MVFR conds due to br develop by 09-12z. VFR conditions are expected
on Wednesday. Isolated-scattered rain showers and thunderstorms and rain are again possible during the afternoon
and evening, but the probability remains too low to include in
prevailing forecasts.
