.NEAR TERM...
(Today)
Issued at 357 AM CDT Thu Mar 26 2026

Mostly clear skies and dry conditions exist across the local
forecast area early this morning, with temperatures currently
ranging from the m-u 50s in northeast AL to the l-m 60s elsewhere.
Due to a light southerly wind and potential impacts from both
mid-level clouds (related to a weakening vort max dropping into
the Central-OH Valley) and lower-level stratus (developing to our
southwest) temperatures may not fall much before sunrise, with
only a limited risk for fog development near lakes and other water
sources. Over the course of the day, a 500-mb ridge (extending
off a subtropical high over northern Mexico) will build eastward
across the southern Plains and Gulf Coast states, with broad scale
subsidence ensuring warm/dry conditions and limiting clouds to a
scattered-broken coverage of fair-weather cumulus. This, in
conjunction with modest SW flow in the boundary layer, will result
in warm afternoon temperatures ranging from the m-u 70s in higher
terrain to the l-m 80s in the valley.

.SHORT TERM...
(Thursday night through Saturday night)
Issued at 947 PM CDT Wed Mar 25 2026

Warm conditions will continue through Friday until a weak upper
wave moves through the area bringing a cold front through Friday
night into Saturday. With limited moisture and the lack of
stronger synoptic support, we will maintain only low to medium
(20-40%) chances for rain ahead of the front Friday afternoon as
winds veer from the SW to NE. The main concern for the short term
period will be the increasing potential for dangerous fire
conditions and a Red Flag Warning may be needed in future forecast
updates. The combination of afternoon RH values below 30% Saturday
afternoon and gusty NE winds will greatly increase the risk of
wildfires in conjunction with the ongoing severe drought
conditions. Please be mindful of this as we head into the weekend
and check the forecast before doing anything that could result in
an un-contained open flame.

Temps will be noticeably cooler Friday night through Saturday as
lows fall to the upper 30s/low 40s Saturday morning and highs
reach the low to mid 60s Saturday afternoon. Winds should begin to
subside Saturday night with lows again in the upper 30s/lower 40s.

.LONG TERM...
(Sunday through Wednesday)
Issued at 947 PM CDT Wed Mar 25 2026

The primary feature to focus on in the long term will be an upper
level ridge forecast to push eastward from the southern plains
towards the Tennessee Valley through mid week. In return, subsequent
sfc high pressure will allow mostly dry conditions and a gradual warm
up in temperatures. High temperatures are forecast to increase from
the upper 60s/lower 70s on Sunday to the mid 80s on Wednesday.
Overnight lows during this timeframe will drop into the 40-50s both
Sunday and Monday night. Tuesday night will be more mild with lows in
the mid 50s to low 60s. Tuesday evening into Wednesday, a shortwave
trough is forecast to push in behind the ridge as it shifts toward
the Carolinas. This shortwave will allow low chances (30% or less) of
rainfall through our area (primarily north of the TN River).
Confidence is low due to slight model disagreement in the placement
of sfc high pressure, so have continued with blended guidance. If the
sfc high is able to hold its position over the FL peninsula, this
will allow mostly dry conditions through the area as rainfall chances
are kept to our north.

.AVIATION...
(12Z TAFS)
Issued at 639 AM CDT Thu Mar 26 2026

There have been no changes to previous aviation forecast
reasoning as VFR conditions will exist today, featuring a broken
layer of As early this morning and a sct-bkn fair-weather Cu field
later this morning (which should dissipate by 23Z). Sfc winds
will veer to SSW by 15Z and increase to 9G17 kts (before
diminishing once again around sunset). There are some indications
that a lower (perhaps MVFR) stratus layer may return btwn 9-12Z,
but we have not included this in the current TAFs. Patchy BR/FG
may also develop early Fri morning in protected valleys and near
large bodies of water, but should not have an impact at the
terminals.
