.SHORT TERM...
(Rest of today through Sunday)
Issued at 1120 AM CDT Sat Jul 4 2026

The 12Z OHX upper air data showed a "worked over" atmosphere with
much less convective energy after yesterday`s widespread storms.
Conditions should stay quiet into the early afternoon, then we
will see 20-30 percent coverage of scattered storms late this
afternoon and evening. Along with much less coverage than
yesterday, the intensity will be lower with just isolated gusty
winds and downpours. We will need to keep eyes to the skies and on
radar, but most celebrations and fireworks should be in good
shape.

The Heat Advisory for some triple digit heat index values lasts
until 8 PM. It is not as hot today as it has been, but still
warmer than usual, so just be careful and stay hydrated.

Through the rest of the weekend, conditions will be very warm and
humid, but not unusually so. We will not post heat headlines for
Sunday with highs expected to reach the more typical upper 80s and
lower 90s and peak heat index values around 100. The strong ridge
will be gone and a series of disturbances will be coming in from
the west northwest. This will set us up for scattered showers and
storms, mainly in the afternoon and evening hours. We are not
under a severe outlook, but a few strong storms with gusty winds
will be possible- a pretty common scenario for summertime.

.LONG TERM...
(Sunday Night through next Saturday)
Issued at 1120 AM CDT Sat Jul 4 2026

Through the week ahead, our area will be in a weak mid/upper level
trough pattern with a diffuse surface boundary near the area.
This will lead to scattered showers and storms each day, mainly in
the afternoon and evening hours. There will be a couple of
stronger waves that will enhance coverage at times. The greatest
coverage of showers and storms is indicated Monday and Friday
with low to medium coverage between these systems.

Highs through the week will be mostly in the mid 80s to low 90s
and lows will be in the upper 60s to mid 70s. No organized severe
wx threat is apparent at this time, but a few storms with damaging
wind gusts and heavy downpours cannot be ruled out during the peak
heating times each day.

.AVIATION...
(00Z TAFS)
Issued at 606 PM CDT Sat Jul 4 2026

VFR conditions expected to prevail this evening. Scattered showers
and storms may impact terminals, with highest chances for KCKV
this evening. Low to medium confidence on fog for KCSV and KSRB
overnight. Higher chances for scattered showers and storms
tomorrow afternoon, but coverage and timing still not confident
enough for predominant mention in the forecast. Left PROB30 for
now to end off the TAF period.
