The radar

The Northeast Alabama radar (KHTX), 114 km from the middle of the area, began a volume at 20:55 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Peachtre/Fal Fld, GA (KFFC), launched 12:00Z, 8.9 hours before the alert went out and 129 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

.DISCUSSION...
(This afternoon through Monday)
Issued at 123 PM CDT TUE AUG 11 2026

This afternoon:
Elongated ridging extends from over the Southern
Plains southeast to across much of the Florida Peninsula while two
shortwaves are moving southeast over the Ohio River Valley and
Central Appalachian regions. Surface high pressure is centered
across the far southeast portion of the state with some weakness
in the ridging across the northern and eastern counties, where
shower and thunderstorm activity has already developed and is
currently increasing as of early afternoon. Expect chances for
showers and storms to be best across the northeast and eastern-
central counties with lowest chances southwest. High temperatures
will range from the upper 80s far east to the mid 90s far
southwest. Winds will be from the west to southwest from 4-8 mph.

Tonight:
The mid-level ridging will consolidate more over the Northern
Gulf Coast region tonight while surface high pressure remains
centered just to our southeast. Expect lingering shower and storm
activity to decrease through the evening with fair skies overnight
with light southwest winds 2-4 mph. Low temperatures will range
from the lower 70s far east and northeast to the mid 70s west and
southwest.

Thursday:
Mid-level ridging will remain centered over the Northern
Gulf Coast on Thursday while surface high pressure builds more
over the southern and western portions of the area, resulting in
isolated shower and storm activity expected across the eastern
third of the area with lowest chances west. High humidity will
persist and with higher temperatures, will result in heat index
values reaching 105 degrees in portions of our western and central
counties. A Heat Advisory will be in effect from 1 pm through 9
pm.

Long Term:
The long-term portion of the forecast will feature
strengthening mid-level ridging as it becomes centered over
Central Mississippi by this weekend. Surface high pressure will
migrate further northwest, becoming centered across the Lower
Mississippi River Valley Region by early in the weekend. This
pattern will result in minimal chances for widely isolated shower
and storm activity primarily confined to the far east and
southeast portions of the forecast area. Concerns for persistent
heat stress will increase with a multi-day episode of heat indices
exceeding 105 degrees and potentially approaching 110 degrees in
some spots though the weekend and into early next week. Some spots
may fall back into D0 drought category if these conditions do
persist into middle next week.

.AVIATION...
(18Z TAFS)
Issued at 1207 PM CDT TUE AUG 11 2026

Expect VFR conditions to continue into early afternoon, except
where clouds build that will support chances for showers and
storms with best potential across the eastern portion of the
area, near BHM, EET and AUO where PROB30 groups are maintained
from 20z to 01z. This potential is too low to include at MGM and
TCL for this issuance. Showers and storms will gradually decrease
through the mid to late evening hours with VFR conditions
returning overnight.

Note: AMD NOT SKED for AUO due to a weather observation outage.

05

&&

.FIRE WEATHER...

Humid conditions will keep minimum relative humidity values near
or above 50% through Thursday. As ridging builds Friday,
conditions will turn slightly drier, with MinRH values dropping
into the mid 40 percent range in the southwest. By the weekend,
MinRH values will further decrease to near 40% across western and
southwestern counties. Winds will remain light through the
period. While isolated to scattered showers and storms will
persist through late week, the activity will become very isolated
and more confined to eastern areas over the weekend. Elevated
fire weather concerns will remain low over the next seven days.
