.SHORT TERM...
(This evening through Tuesday)
Issued at 1243 PM CDT MON SEP 22 2025
The southern humidity has mostly returned that we`re used to
during this time of the year, as southeasterly flow and moisture
advection have increased dewpoints into the upper 60s and lower
70s at midday. A weak easterly wedge was still present over
Central Georgia, but is weakening overall as the surface ridge
begins to retreat to the north and east from the Carolinas. An
upper level shortwave along with 500mb trough axis is currently
moving east and will traverse the Ohio River Valley through the
rest of the day today. Widespread coverage of showers and storms
will remain off to our north as a result, but isolated to
scattered storms will remain in the forecast for a good portion of
our forecast area. CAMs are indicating best coverage across
western and northwestern counties through this afternoon, and PoPs
have been updated into the chance category as a result. Elsewhere,
isolated development is forecast as temperatures rise into the
lower 90s with additional humidity to factor in. What will be a
bit of a change today compared to the past several days will
include fairly breezy southerly winds as a pressure gradient sets
up across the region. We can expect prevailing winds around 10mph
with a few gusts up to 20mph, especially for counties along the
U.S. Highway 278 corridor.
Following another mild night in the 60s as winds diminish overall,
the upper trough axis will lift to the north and east, keeping our
area mostly dry, except for a few isolated to scattered showers
and storms during the afternoon on Tuesday. Surface ridging will
broaden westward from the southwest Atlantic, keeping much of the
central Gulf Coast dry and hot. A pocket of dry air aloft will
also keep a lid on convective development despite southerly
surface flow. Temperatures could be a degree or so warmer overall,
topping out in the lower 90s with a few pockets of mid 90s.

.LONG TERM...
(Tuesday night through next Sunday)
Issued at 205 AM CDT MON SEP 22 2025
Next big weather maker for central Alabama comes in the form of an
upper level trough that is forecast to dig into the eastern CONUS
the middle to end of this week, and an associated surface cold
front passage. These features should bring some much needed rain
to our area. Time period for highest chances of showers and storms
will be from Wednesday afternoon through Thursday night. Looks
like just about all of central Alabama will get some rain during
that time frame, with average amounts expected to be around an
inch to an inch and a half. Will need to watch details on
mesoscale features, especially in the Wednesday afternoon to
Thursday afternoon time frame. There`s obviously bound to be some
instability around. If the upper trough can muster a strong enough
surface low to enhance shear levels, then there`s a non-zero
chance of some severe storms.
Temperatures behind the front will still be slightly above
seasonal averages, rather than significantly above like we`ve seen
recently.

(00Z TAFS)
Issued at 650 PM CDT MON SEP 22 2025
We have a low chance for a few showers or tstorms scrap the NRN
TAF sites, during the evening, but chances are too low to mention
and pinpoint in TAFs. Will be monitoring for any needed amendments.
Otherwise, look for VFR TAFs outside of isolated convection with
off/on mid/upper clouds. Winds will be generally light/variable
overnight, with S-SW winds during the day with mixing 5-8kts.
There is a slight chance for afternoon TSRA again on Tue across
the NRN 1/3 of the state, but chances are too isolated to pinpoint
for TAFs ATTM.

.FIRE WEATHER...
MinRH values will continue to stay in the 30-40% range through
Tuesday, with scattered shower and storm chances remaining in the
forecast. Higher rain chances are expected starting on Wednesday,
perhaps lasting as late as Friday, as a cold front moves across
the region. A wide range of RH values are expected during the day
on Wednesday from northwest to southeast, as showers and storms
move into northwest Alabama during the afternoon. Northwest
counties will see RH values of 60+ percent, while RHs are expected
to mix into the upper 30s to lower 40s along and south of the
I-85 corridor.
