.SHORT TERM...
(Rest of today through Sunday)
Issued at 1102 AM CST Sat Nov 9 2024

Showers continue to move north and east this morning, and obs
sites west of the TN river are now showing some of that precip
reaching the ground. CAMs show showers running into drier air over
the mid state early this afternoon for most of the area before
finally able to break through later in the afternoon and
especially this evening. Areas west of I-65 will likely see
showers put down a tenth to maybe three quarters of an inch of
rain before this evening. As the strong Plains low continues
northward, additional WAA and moisture will move in, and will
allow for some thunderstorms to develop this evening and
overnight. Not expecting anything severe with the lack of stronger
instability but there is decent deep layer shear that could yield
some gusty winds with any stronger updrafts. Southerly winds will
remain strong overnight outside of showers and storms, with speeds
around 10 to 20 mph and gusts as high as 30 mph, especially at
higher elevations. Cold front will push east Sunday, and rain
chances will also increase and push east during the afternoon
hours. Rain chances should come to an end Monday morning and the
front will be completely through the mid state by then also.

.LONG TERM...
(Sunday Night through next Saturday)
Issued at 1102 AM CST Sat Nov 9 2024

After the rain moves through Sunday night, we are still looking at
around a half inch to an inch on the Plateau, and 1 to 2 inches
for the rest of the mid state through the weekend. Drier air will
move in Monday with somewhat zonal flow aloft. A weak shortwave
trough will move into the region Tuesday but looks dry, and
ridging will move in right behind it. The ridge will be short
lived as a stronger trough moves east from the Plains later on
Wednesday, and will bring in our next shot at rain. Ensembles are
not in complete agreement on timing yet, and even the
deterministic solutions are not completely on board with rain
Wednesday into Thursday. But nevertheless that trough will be our
next shot at seeing more needed rainfall across the area. Models
do agree that we will be a little cooler after this trough, with
highs in the 60s Thursday through Saturday and lows in the 40s for
most of the mid state. Drier weather returns Thursday into next
weekend.
