.SHORT TERM...
(Tonight through Sunday Night)
Issued at 602 AM CDT Sat Oct 11 2025
Calm conditions persist across Middle TN tonight as a centered
area of high pressure sits just off to our northwest.
Temperatures will cool into the upper 40s to low 50s overnight
with areas of patchy dense fog. The HREF is giving portions of
the southern CWA and along the Plateau a 60% to 70% chance of
visibility dropping below a 1/2 mile with only pockets of dense
fog elsewhere across the CWA. Be cautious of this overnight if
have to travel. Saturday`s forecast continues our dry and warm
stint with less cloud coverage as the low over the Great Lakes
pushes ever so slightly east. Afternoon temperatures will in turn
be a touch warmer, near 80 degrees.

.LONG TERM...
(Monday through next Saturday)
Issued at 602 AM CDT Sat Oct 11 2025
The long term synoptic pattern is a busy and progressive one, though
Middle TN`s position in it all favors continued dry and warming
conditions. A large ridge present over the central US will
gradually build east through the week, keeping rain chances near
0% with a gradual warming trend. With northwesterly flow aloft,
instances of increased high cloud cover will be likely, most
notably mid- week when an upper level disturbance rounds the base
of the ridge, moving through the Ohio River Valley. No rain
expected with this feature, but a temporary slight decrease in
temperature looks to follow it. Overall, temperatures in the long
term will be a few degrees above-normal with highs in the low to
mid 80s, but not too far off from seasonal norms. For context, the
normal high at Nashville for this time of year is 76. With the
prolonged period of no rain, this will likely exacerbate ongoing
drought conditions.
