.KEY MESSAGES... 
Updated at 1107 PM CDT Wed Jul 29 2026

- Dangerous heat will remain the primary concern today. Peak heat
  index values up to 110 degrees remain possible, with limited
  overnight relief. Heat continues to back down Friday with heat
  index numbers lower than heat advisory criteria through the
  weekend 

- Afternoon/evening scattered rain chances increase today through
  the upcoming weekend as a front drifts into the area from the
  north. Repeated thunderstorms may produce locally heavy rainfall
  and localized flash flooding, especially where storms train.
  Additionally, a few isolated strong storms will be possible with
  gusty winds in excess of 40-50mph the main risk.

.SHORT TERM...
(Now through Sunday) 
Issued at 1107 PM CDT Wed Jul 29 2026

Not difficult to find the backdoor front that is to the north and
east of the area moving slowly SW this morning. This front will 
stall today over or very close to the area and provide a corridor 
for sh/ts to develop and move. Most activity will develop during 
the heat of the day, so we should reach heat advisory conditions 
just as storms begin to develop. This should be a rinse and repeat
for Fri as well. But we will begin to see a cold front moving SE 
at at a good pace by late Fri reaching our area by late Sat before
stalling along or near the coast. Plenty of moisture along and 
ahead of the weekend front will help develop a good bit of sh/ts 
through the day as we reach convective temps which will be a bit 
lower over the weekend. Not everyone will get storms each day but 
most locations should get some rainfall at some point through the 
weekend.

.LONG TERM...
(Sunday night through Wednesday) 
Issued at 1107 PM CDT Wed Jul 29 2026

The globals have come into somewhat better agreement with the ECM 
and GFS indicating an ULL over portions of the southeast to start 
the long term. Exact placement is still somewhat off with the latest 
GFS across the deep south and the ECM over the Tennessee River 
Valley. At the surface, not much of a change with the surface 
frontal boundary still meandering over the northern central Gulf 
Coast. In this pattern/solution, expect rain chances to reside into 
the start of the new workweek next week. If the GFS is anywhere 
close to being correct the upper levels will be quite chilly, which 
could lead to some locally stronger cells with small hail during 
peak heating when instability is maximized. 

Going into Wednesday, both the GFS and ECM are roughly the same 
although temporally there are some slight changes. An H5 kicker from 
the north will dig just enough to grab the low in both models, but 
this occurs a bit quicker with the GFS. So the cold core low will 
not hang around very long before it opens up and moves downstream by 
mid week and with ECM only showing the low a bit further away, any 
time issues would be somewhat irrelevant in terms of sensible 
weather. There remains nonzero diurnally driven convection chances 
on Tuesday and Wednesday, however, the signal within the globals is 
a bit weaker as it appears the surface front will begin to decay 
late in the period.

Temperatures will start off somewhat cooler than normal with the 
upper level low over the region and continued rain/cloudiness during 
peak heating. But, if the globals are correct, inversely, as the 
POPs decrease temperatures should begin to increase, especially with 
the heights starting to rise. (Frye)

.AVIATION...
(06Z TAFS)
Issued at 1107 PM CDT Wed Jul 29 2026

VFR for most of the day at all sites. There will be 
better chances of TSRA today to show in this taf set with the 
possibility of MVFR to IFR conditions while the strongest move 
through.

&&

.MARINE...
Issued at 1107 PM CDT Wed Jul 29 2026

High pressure over the southeast gulf will keep a predominantly 
westerly to SW flow regime through the remainder of the week. There 
will be the usual diurnal increase in winds over the eastern waters 
where winds approach and sometimes slightly exceed 15 knots during 
the evening and part of the overnight hours before diminishing. A 
weak front will settle toward the northern gulf Thursday and remain 
nearby through the weekend, bringing increasing thunderstorm 
coverage. Seas will generally remain 1 to 3 feet nearshore and 2 to 
4 feet offshore, although locally hazardous winds, waves, lightning, 
and reduced visibility will occur near stronger storms.

Areas affected...Alabama through Eastern Kentucky

Concerning...Heavy rainfall...Flash flooding likely

Valid 012044Z - 020230Z

SUMMARY...A line of training thunderstorms has formed in a highly
unstable and moisture rich environment from northern Alabama
through Eastern Kentucky. Flash flooding likely.

DISCUSSION...A series of lines of thunderstorm cells are setting
up across northern Alabama and eastern Tennessee this afternoon.
These storms are moving northeastward as the lines they are
embedded in move east, thus allowing for some limited training.
Across Alabama, SPC Mesoanalysis shows SBCAPE values close to
5,000 J/kg near the Mississippi border near Hamilton, Alabama. The
nose of instability extends into central Tennessee and Kentucky
with SBCAPE values around 3,000 J/kg. Southwesterly flow ahead of
the advancing cold front is advecting plentiful moisture
northeastward ahead of the front, allowing the storms to blossom
in coverage as they track off towards the northeast. There are a
few segments where the storms have done a better job merging west
of Knoxville, but it's likely that these storms will congeal into
a solid line or two over the next few hours. For now, the storms
are only producing rainfall rates up to an inch per hour, but as
they organize in this highly unstable and moisture-rich
environment, expect the rates in the strongest cores to rapidly
increase. Rainfall rates will be highly dependent on the speed of
the storms, despite expected high instantaneous rainfall rates.
Local rates will approach 3 inches per hour, with isolated rates
to 4 inches per hour where cell mergers and cold pools locally
slow the movement of any stronger cores.

Urban areas such as Birmingham, Chattanooga, and Knoxville are
likely to be impacted by storms capable of producing heavy
rainfall over the next several hours. These urban areas will have
a greater risk of flash flooding as a result. Meanwhile, low-lying
and particularly flood prone areas, especially into northwest
Georgia, eastern Tennessee, and eastern Kentucky where terrain
becomes a significant factor could also see localized flash
flooding in a few hours as the storms move through.

CAMs guidance suggests there will be a single concrete line of
storms on the western end of any convection associated with the
approaching cold front. However, scattered segments of storms are
likely to continue forming out ahead of the main line, seemingly
at random. Areas that are hit with multiple rounds of heavy rain
in quick succession will also be susceptible to localized flash
flooding into this evening.

* WHAT...Heat index values up to 110 expected.

* WHERE...Portions of southeast Louisiana and southern Mississippi.

* WHEN...From 11 AM to 7 PM CDT Thursday.

* IMPACTS...Hot temperatures and high humidity may cause heat
  illnesses.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Drink plenty of fluids, stay in an air-conditioned room, stay out of
the sun, and check up on relatives and neighbors.

Take extra precautions when outside. Wear lightweight and loose
fitting clothing. Try to limit strenuous activities to early morning
or evening. Take action when you see symptoms of heat exhaustion and
heat stroke.

To reduce risk during outdoor work, the Occupational Safety and
Health Administration recommends scheduling frequent rest breaks in
shaded or air conditioned environments. Anyone overcome by heat
should be moved to a cool and shaded location. Heat stroke is an
