.KEY MESSAGES...
Issued at 242 PM CDT Sat Jul 4 2026

- The usual summer heat and humidity continues through the 4th of
  July holiday weekend, along with the chance for rainfall.

- Upper ridge axes to our east and west will leave our region in
  an induced area of weak troughing, opening the door for daily
  showers and thunderstorms to continue into early next week.

- Slight forecast uncertainty remains beyond the middle of next
  week with increasing signals that ridging will begin to exert
  greater influence across our region late next week, which would
  mean a trend toward hotter and drier conditions once again.

.DISCUSSION...
Issued at 242 PM CDT Sat Jul 4 2026

A warm and humid day for this 4th of July Holiday. Isolated to
scattered convection has already developed across portions of the
area, as a trough axis has moved into the region in wake of a
departing ridge off the Atlantic Coast. With several hours of peak
heating remaining, expect more convection to develop over the
region. Some of this convection could produced locally heavy
rainfall and downburst winds, which has been highlighted by a
Marginal Risk from the Storm Prediction Center today. It won`t be
a total washout today, so for those outdoors, please take the
appropriate precautions for both heat and lightning safety, along
with other hazards from thunderstorms. Remember, When Thunder
Roars, Go Indoors!

Short-term progs suggest we will see a break in activity this
evening, but rain chances could return early Sunday morning. An
upper ridge is developing over the Southwest CONUS into western
Texas, while long-wave troughing is in place over the eastern half
of the CONUS. This will put our region in northwest flow by
tonight. Models are developing a MCS across southern Kansas into
northeastern Oklahoma and adjacent northwest Arkansas. This MCS is
expected to dive southward overnight, possibly arriving in our
extreme northwestern zones near daybreak. There is some hint that
these storms could diminish, but more storms could redevelop on
the residual outflow boundary, possibly producing damaging winds
as it shifts southward.

Rain chances are expected to remain in the forecast through at
least the first half of next week, as weak troughing will remain
across the region. Although uncertainty remains beyond the middle
of next week, models continue to hint at the return of upper
ridging over the region, which would give us a break from the
rain. It would also bring warmer conditions back into the region
as well. /20/

(00Z TAFS)
Issued at 621 PM CDT Sat Jul 4 2026

For the 05/00Z TAFs, scattered strong to severe thunderstorms
continue across southwest Arkansas and portions of north central
Louisiana, expected to dissipate within the next few hours. High
clouds will prevail for much of the night with quiet conditions
until another round of storms approaches out of southern Oklahoma
in the pre-dawn hours. Storms will introduce MVFR CIGs and brief
gusty winds, continuing into the afternoon across our eastern
airspace. Winds will otherwise be light and variable throughout.
