.NEAR TERM...
(Today)
Issued at 133 AM CDT Thu Oct 2 2025

Not as concerned about fog this morning, however cannot rule out
some patchy fog in the usual spots. With Imelda well off into the
Atlantic, the ridge of high pressure that has been anchored in
place the past few days up in the Great Lakes down to the MS
Valley, will be able to slide eastward. This will allow for it to
be better established across the Southeast today. The building
heights and plentiful amount of sunshine will give way to daytime
highs above seasonal norms, ranging from the low 80s (NE AL) to
upper 80s (elsewhere). For reference the normal high for the start
of October is 81 degrees at KHSV and KMSL. The pressure gradient
increase will get east/northeasterly winds to 5-10kts with gusts
up to 15kts.

.SHORT TERM...
(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.

VFR conditions will prevail at KHSV and KMSL through the TAF
period. Easterly winds will quickly pick up after sunrise and
become ~10kts with gusts up to 15kts. Winds will weaken with
sunset but remain elevated overnight.
