Issued at 239 PM CDT Thu Jun 5 2025

This Evening/Tonight through Mid-Day Tomorrow...

Spotty convection looks to be the order of the day for this rest of
the day, spurred by low level instability and day time heating.
These showers and garden variety thunderstorms are expected to
persist until an hour or two after sunset yielding to benign weather
conditions tonight through mid-day tomorrow.

Mid-Day Friday & Saturday...

A shift in the upper level pattern will allow more vibrant
convection to take hold during the afternoon, especially along
through the northern half of the CWA; where instability is
strongest. There is some uncertainty as to the exact
characterization of this activity, should our northwesterly flow
vector be more robust we should expect a smattering of severe cells.
Should that same flow waver there could be only a few short lived
severe cells. Again sunset will make way for reduced diurnally-
induced instability which will cause our showers/thunderstorms to
dissipate after nightfall. Saturday will see a strengthening of
unstable indcators driving a more widespread area of potential
severe weather encompassing the entire CWA (Marginal 1/5 south of I-
20, and Slight 2/5 North of I-20). In either case there will not be
deep synoptically organized forcing which should keep any severe
impacts relatively localized.

Sunday through Next Thursday...

Broadly speaking, daytime showers and thunderstorms across the CWA
are expected, with the aforementioned instability lingering in the
area. Similarly night time conditions are progged to be relatively
cool (lows in the high 60s to low 70s) and quiet as convection dies
down with nightfall. It should be noted that while at this point we
are not confident enough in severe weather parameters to message
those impacts via the forecast/graphics, don`t be surprised if that
shifts in the coming days especially if upper-level disturbances
overachieve./OAJ/
