.SHORT TERM...
(Today through Thursday)
Issued at 110 AM CDT WED SEP 17 2025
Additional subtle impulses aloft will drift southward
atop our region today, guided by a low pressure system over
coastal Virginia. In the low levels, a broad pattern of confluence
will continue. This setup will support isolated shower and
thunderstorm activity at times.
As suggested by models yesterday, we`ve a batch of showers and a
few thunderstorms moving south from Tennessee (at 1:10 am
Wednesday) along a low-level axis of convergence and outflow
propagation. This activity should primarily affect areas northeast
and then east of Birmingham through the early-morning hours.
Additional isolated activity is forecast to dot central Alabama
this afternoon. Then, high-resolution models again show a
southward-moving, low-level axis of lift Wednesday evening/night,
with a few CAMs suggesting spotty activity between the 20 and 85
corridors during this time. Overall, afternoon to evening shower
and thunderstorm activity won`t be significant due to limited
coverage and duration, but certainly welcome where it occurs.
The Mid-Atlatic low pressure system will zip northeastward
Wednesday night into Thursday as it is absorbed by a larger
trough to its north. This will allow shortwave ridging to
overspread our region. While the forecast does not include any
shower/thunderstorm chances at this time for Thursday, it`s
conceivable that a few cells could develop along an axis of
somewhat higher PWAT values draped across part of the Gulf Coast
region. A ~10-20% chance may be introduced pending trends.
High temperatures will run between 5-10 degrees above seasonal
normals, with upper 80s to lower 90s forecast for today and more-
so in the lower 90s for Thursday.

(Thursday night through next Tuesday)
Issued at 110 AM CDT WED SEP 17 2025
Above-normal warmth, by a margin of between 5-10 degrees,
continues through late this week, along with nil to very limited
shower/thunderstorm chances. A pattern of troughing is then
progged to develop next week, which should allow us to shave a few
degrees off temperatures with a chance for diurnally driven
showers and thunderstorms, though chances are low at this time
(~20 percent).

.AVIATION...
(06Z TAFS)
Issued at 110 AM CDT WED SEP 17 2025
The only interruption to VFR conditions through the TAF period
will come from isolated showers and thunderstorms. The first
instance could affect ANB through 12z this morning. The second
chance comes this afternoon and evening as isolated activity
develops across central Alabama, focused between 18z-03z. There
isn`t a formal mention in the TAFs, and may come down to
satellite/radar trends given the spotty and brief nature of
activity. Winds will be calm overnight then variable around 5
knots during the day.

.FIRE WEATHER...
D0 to D1 drought conditions are most prevalent across the western
half of Alabama, though locations elsewhere are trending in this
direction. Through the weekend, afternoon RHs as low as the lower
to middle 30s are forecast, along with minimal shower and
thunderstorm chances, and light winds (
