.DISCUSSION...
Issued at 1103 AM CDT Fri Jul 4 2025

Recent radar imagery has a broken line of showers and
thunderstorms moving northeastward toward the TX/LA state line,
with the heaviest band being north of the I-20 corridor. These
weak showers will continue to develop and move eastward across the
region today. Exact timing and coverage remains uncertain, as
the driving force behind the showers are extremely weak. Like the
typical summer afternoon storms, these will gradually diminish
through the evening, with East Texas likely being the last to dry
up. The overnight hours are looking to stay dry enough after the
showers die for firework shows to continue as planned.

The upper-level ridge that has stayed in place overhead in recent
days will begin to lose amplitude and progress eastward beginning
on Saturday. But the intensifying high pressure over the Desert
Southwest will replace the effects of the ridge in portions of
East Texas by the end of the weekend. The lack of widespread rain
and cloud cover, along with the southwesterly flow at the
surface, will begin another warming trend for the Ark-La-Tx.
Afternoon highs for next week look to be in the mid to upper 90s,
which will cause widespread heat indices of 100+. Several areas
will be flirting with Heat Advisory criteria and will likely be
the main weather concern for early next week.

Long-range guidance is suggesting that the typical afternoon
thunderstorms will still be in play despite the high pressure
dominating the forecast. However, the strength of the high
pressure out west looks to be enough to largely inhibit
convective development for areas west of I-49. This may change
later in the week, as models are beginning to hint at a shortwave
trough riding the upper-level flow through parts of the Missouri
Valley. There are plenty of "if"s in that scenario that would
need to be in place to bring some relief from the heat. But
overnight lows in the 70s will have to do for the time being. /57/
