With the "severe" weather out of the way, I did a quick once over
for the wintry potential tomorrow and it does look like we could
be in for a changeover from light rain in the morning to a rain-
snow mix by the afternoon commute. Temperatures and the amount of
precipitation should be such that there shouldn`t be any impacts
tomorrow afternoon/evening, however as we move into the overnight
hours Tuesday night, cold enough air is expected to allow a
changeover to all snow. Now, the timing is going to be key for the
western 2/3 of Middle TN. QPF might shut off prior to the coldest
air reaching the area. For this reason, I`m going to hold pat on
no accumulations for the western 2/3. The Cumberland Plateau could
very well be a much different story. While I`m not going to issue
one right now (I`ll let the midnight shift make the final call on
this after more analysis) there could very well be the need for a
Winter Weather Advisory on the Plateau for tomorrow night.
Snowfall accumulations might be on the order of 1-1.5 inches by
Wednesday morning. Again, more on this later with the full
forecast package.



IFR cigs will push in from the north over the next several hours,
eventually affecting all mid-state terminals. Conditions will
begin to improve by late morning, however, light rain will start
to move in around the same time. As we move into the late
afternoon hours, cold air will filter in and a changeover to a
rain/snow mix, then all snow after 00Z Wednesday.

Winds will be calmer tonight, but as the light rain pushes in late
Tuesday morning, winds will begin to pick up. NW gusts of 22-25
kts will become likely for the rest of the TAF cycle.
