Overall, there have been no significant changes to forecast
reasoning for the near term period since the update earlier this
morning. A gradual increase in the coverage of generally
thin/translucent cirroform clouds is anticipated to continue this
afternoon and overnight, related to strengthening diffluent flow
aloft to our west (between a weak mid-level trough currently
dropping into the Lower MS Valley and a convectively-induced vort
max across eastern KS/western MO). However, this should have no
impact on highs temperatures this afternoon as surface
observations indicate readings in the u70s-l80s. Overnight lows
will indeed be a bit warmer compared to last night (m50s-l60s),
but this will largely be due to a subtle increase in boundary
layer dewpoints today. With a light easterly breeze predicted to
continue for much of the overnight period, any brief development
of patchy mist/fog should be confined to sheltered valleys.

.SHORT TERM...
(Tuesday through Wednesday)
Issued at 1030 AM CDT Mon Sep 8 2025
A shortwave from a departing upper trough over the Midwest and
Great Lakes regions looks to move over the Tennessee and Ohio
valleys Tuesday and into midweek, but upper ridging will build
quickly behind it over the Mississippi River Valley for later in
the week. This shortwave feature may bring some cloud cover to the
region Tuesday morning and into the afternoon, but no appreciable
moisture is anticipated with it. Meanwhile, surface high pressure
will largely remain dominant through at least midweek. Although
the aforementioned high spanning from the northeast down into the
ArkLaTex shifts east a bit, another high pressure will quickly
dive down over the eastern US from Wednesday into Thursday.
Overall, the days without rain will continue through midweek (and
beyond, but please see the discussion below for long term
details). The main story through midweek will be an upward trend
in temperatures. Highs are forecast to increase into the mid to
upper 80s by Wednesday, with lows in the upper 50s to around 60
degrees for most locations; although, northeast Alabama and
portions of southern middle Tennessee will be slightly cooler. The
good news is, with dew points in the 50s/60s, it will not be as
humid!

.LONG TERM...
(Wednesday Night through Sunday)
Issued at 1047 PM CDT Sun Sep 7 2025
The upper high/ridge will continue to push east toward the late-
week period and will keep temperatures on the rise as we head into
the weekend. The moisture-rich airmass will remain to our south so
the dry forecast will persist, but the summer heat is not quite
done with us yet. In fact, temps will approach the mid 90s in
western locations by Friday as the H85 high becomes more centered
over the eastern CONUS. The good news is that with dewpoints
limited to the 50s and lower 60s, heat indices will remain below
the 100 degree mark so we do not anticipate any heat related
headlines at this time.
