.UPDATE...
Issued at 633 PM CDT Sun Sep 7 2025
High pressure is set up to our north and that has brought great
weather today. That quiet weather will continue into the overnight

not expected to be a concern tonight. Lows will chilly falling
into the 40s for most.

.SHORT TERM...
(Rest of today through Monday)
Issued at 1141 AM CDT Sun Sep 7 2025
After quite the foggy start to the day, northerly winds have
picked up enough to help clear things out. Cold air advection
continues today over Middle TN though the trough that has been
over us for several days now is becoming less amplified as it
shifts east. Have brought afternoon temperatures below NBM
guidance again today to account for continued CAA, though today
will be warmer than yesterday with much more sunlight present.
Highs will warm into the mid to upper 70s this afternoon with a
steady northerly wind. Dew points temperatures will progressively
fall through today, too, making for a very pleasant and
comfortable afternoon. Lows will drop into the upper 40s/low 50s
tonight under clear skies. Areas of patchy fog will be possible
again, though not as widespread as winds will stay near 5mph
overnight. Monday looks great with temperatures warming into the
low 80s and passing high clouds during the afternoon.

.LONG TERM...
(Monday Night through next Sunday)
Issued at 1141 AM CDT Sun Sep 7 2025
The long term forecast looks hot and dry. Temperatures will
eventually return to the upper 80s to low 90s by the end of this
week. There will be a weak disturbance aloft that moves through
Tuesday, but at this time, only an increase in cloud coverage looks
to accompany it. A large ridge building across the western US will
keep surface high pressure near or over us the whole week. As this
feature continues its trek east, temperatures will gradually
increase each day and keep rain and storm chances to nearly 0%.
This is not good news for our growing drought conditions, and
relief does not look to come around anytime soon. The CPC has our
area outlined for continued below-normal precip beyond the 7-day
forecast period.
