.DISCUSSION...
Issued at 200 AM CDT Fri Aug 29 2025

This holiday weekend will be lovely, albeit cooler than normal, for
one last gasp at summertime adventures. Dry conditions linger into
early next week. Surface high pressure hangs over the region until a
cold front pushes through Wednesday, which will break this pattern
of quiet weather, but will potentially usher in even cooler air.

Highs in the upper 70s to low 80s and lows in the mid to upper 50s
are expected to continue through midweek next week. Behind the cold
front on Wednesday, there is a signal for highs to only get up into
the upper 60s and lows in the 40s, starting Thursday. The NBM is
showing a max of a 30% chance that highs get above 70 degrees
Thursday. The LREF is thinking the same with a 20-40% chance of
highs getting above 70 degrees. Looking at the long range models,
temperatures appear to rebound by the following weekend.

Another aspect of this cold front next week is the probability of
showers and thunderstorms. It is still too far out to say for
certain where they will develop and if they will be severe. As of
this forecast, none of the machine learning models are showing ANY
hint that there will be severe weather with the passage Wednesday.
The Euro and GFS show some hint at showers across the CWA Wednesday.
The current forecast shows ~30% chance of showers Wednesday into
Thursday.
