.KEY MESSAGES...
Updated at 1137 AM CDT Wed Aug 5 2026

- Scattered afternoon showers and storms each day. Highest chances
  over the Cumberland Plateau with low chances west of the
  Plateau.

- No severe weather is expected, but a few storms may produce
  gusty winds and heavy downpours.

- Gradually getting warmer and more humid with heat index values
  climbing over 100 most days this weekend through next week.

&&

.SHORT TERM...
(Rest of today through Thursday)
Issued at 1120 AM CDT Wed Aug 5 2026

The key messages tell it all with an unremarkable forecast for
typical August weather.

An upper level low that has been set up for several days over the
eastern part of the state will keep scattered showers and
isolated storms going today and again Thursday, especially along
and near the Plateau. No severe storms are expected with weak
lapse rates. Most activity will die off with sunset. Areas of fog
will form overnight, especially for locations that receive rain.
Otherwise, temperatures will be near normal.

&&

.LONG TERM...
(Thursday Night through next Wednesday)
Issued at 1120 AM CDT Wed Aug 5 2026

The upper low will weaken and get swept away by the weekend. We
will then be within a bridge zone between a strong Bermuda high
and a strong, hot western ridge. This will keep our temperatures
seasonably warm - maybe a degree or 2 above normal. This pattern
will also keep conditions humid with pop-up showers and storms
each afternoon. For the most part, chances/coverage will continue
to be highest (30 to 60 percent) for the Plateau and generally
low (20 to 30 percent) for areas west of the Plateau. No severe
storms are expected, but gusty winds and heavy downpours will
occur with some storms. Heat risk levels will be in the 2-3 range
(out of 4) with peak heat index values pushing mostly into the
100-105 range.

&&

.AVIATION...
(18Z TAFS)
Issued at 1137 AM CDT Wed Aug 5 2026

Isolated to scattered showers and storms will bubble up over the
area this afternoon. Brief cig/vsby impacts are expected at CSV
and SRB, but probs are very low elsewhere. Outside these small showers
and storms, conditions will be VFR with light winds.

For tonight, mainly VFR, but CSV and SRB will have episodes of fog
and stratus, down to LIFR at times.

Daytime Thursday will be a repeat with mostly VFR and a low chance
for afternoon showers and storms.
