(Rest of tonight and Thursday)
Issued at 856 PM CDT Wed Oct 1 2025
A few showers that earlier tried to form over the higher terrain
of the Cumberland Plateau and parts of NW Alabama and NW
Mississippi have dissipated with the loss of daytime heating and
and now less instability. After warm conditions to start the month
of October (high temperatures in the 80s - lower 80s higher
terrain to upper 80s warmest spots), area temperatures as we near
9 PM have cooled into the mid 60s to around 70 with light winds.
Strong surface high pressure now situated over the St Lawrence
Seaway should continue building to the SE over the next few days.
A light easterly flow rounding this high will continue across the
Tennessee Valley for the overnight into Thursday. With mostly
clear skies expected and longer autumn nights, low temperatures
should cool into upper 50s to lower 60s. Despite generally dry
conditions the area has been in the past few days, cannot rule out
late night patchy fog in those more susceptible spots.
The easterly flow will bring ever so slightly cooler air across
the Valley. Even with sunny skies, high temperatures on Thursday
should be a tad cooler, from the low/mid 80s. Winds will be from
the east to SE at 5-10 mph.

(Thursday night through Saturday)
Issued at 856 PM CDT Wed Oct 1 2025
The above noted surface high should take up residence off of the
New England coast as well go through the latter portion of this
week. An E-SE flow should continue over much of the SE CONUS as we
go into the upcoming weekend. This should result in daily high
temperatures ranging from the upper 70s to mid 80s. Low temps will
be noticeably cooler ranging in the 50s (lower 50s east, with
mid/upper 50s west). Dry weather should continue for the remainder
of the week. Sufficient moisture necessary to bring rain chances
to the area should remain to our south given a mean E-SE lower
level flow. Thus the dry spell and more noticeable drought
conditions will continue.

.LONG TERM...
(Saturday night through Wednesday)
Issued at 856 PM CDT Wed Oct 1 2025
Our prolonged period of high pressure influenced weather will
gradually come to an end through the long term forecast. At the
start of the period high pressure at the surface and aloft will be
situated off the Atlantic coast. This will induce ESE flow
bringing Gulf Stream moisture from the Atlantic to the TN Valley.
Locally this will result in a gradual increase in dew points back
to the mid 60s through the start of the work week. Unfortunately
with temperatures remaining in the mid 80s this will mean slightly
more humid conditions than we have been having. The increased
moisture will also amount to low rain and storm chances in the
afternoon through the middle of the week. As we enter the end of
the long term forecast uncertainty increases due to an approaching
cold front. It is uncertain at this time if and when the front
may move through our area. Changes to the timing and location of
the front will impact our rain and storm chances through the end
of the week. While we currently retain low rain chances through
Wednesday, should the front be strong enough to move south through
the area, rain chances will likely increase for mid week.
