.DISCUSSION...
Issued at 215 PM CDT Sun Jul 12 2026

Today through Saturday night: A frontal boundary sinking into the
region from the north is yielding more scattered to widespread
showers and storms across the CWA. Due to the very humid and
unstable environment across the region, in addition to some steep
mid-level lapse rates (6-6.3 C/km), isolated severe storms will be
possible, with damaging wind gusts being the primary concern with
the most intense storms. Heavy downpours and frequent lightning
can both be expected with any of today's convection, and have
added a limited threat HWO graphic to account for some flash flood
potential as moisture convergence will peak along the I-20
corridor this evening. I

While this frontal boundary will eventually washout, due to the
overall troughing/low pressure pattern over the region, combined
with the continued humid and unstable airmass each day, solid
chances for showers and storms will remain in the forecast into at
least Wednesday.  While severe storms currently aren't forecast
after today, given the again overall setup across the region, a few
storms could become intense enough Monday through Wednesday to
produce some gusty winds.  Once again, both heavy downpours and
frequent lightning can be expected with any convection.

Finally, Thursday into the start of next weekend, ridging aloft will
again reassert itself over the region.  While this will lessen the
overall rain chances across the forecast area, the trade-off
currently looks to be a return to hot humid conditions as highs
areawide eventually climb back into the middle 90s Saturday. This
also currently looks to bring back some concern for increased heat
stress yet again during this extended portion of the forecast.
