Don`t get discouraged by the start of the weekend. While on and
off rain showers will plague Middle TN tonight and the
north/central portions of the mid-state will see showers and maybe
even a rumble of thunder tomorrow afternoon, the weekend won`t be
a complete loss.

The showers tonight are a culmination of a "warm" frontal boundary
draped across the area and mid-level energy pushing in from the
northwest. This frontal boundary is expected to pull into southern
KY tomorrow morning and stall out, allowing enough time for a
surface low to traverse it tomorrow afternoon. It`s this low that
will open up a chance for the thunder. While counties along and
north of the I-40 corridor will carry the best chance for rain
tomorrow, it does look like areas closer to the AL state line,
while cloudy, may escape most of the rain. Even if they do see
some, it won`t be much and it shouldn`t be all afternoon.

These northern showers may very well linger into the evening and
overnight hours before the rain lets up going into Sunday morning.
Rains chances fall off drastically Sunday and while we`re likely
to remain mostly cloudy, sun could peek through for many Sunday,
at least for a couple hours. This should help push everybody well
into the 50s and with little wind, Sunday shouldn`t be a half-bad

Evening updates out shortly.



The atmosphere is taking a little longer to saturate than
previously thought, so have raised cigs for a good part of the
forecast for most areas. MVFR Cigs and visibilities may hold off
until Saturday morning as this first wave of precip exits the
area. Saturday afternoon another round of showers is expected,
along with a shift from southwesterly winds to northwesterly
winds as a surface low moves across the mid state. Winds are
expected to remain gusty throughout the day.
