.DISCUSSION...

Issued at 1019 PM CDT Thu Oct 23 2025



The main story for the first portion of the forecast period will be 

the approach of a cold front on Saturday. Ahead of the frontal 

boundary dry conditions will prevail through Friday. As the pressure 

gradient tightens ahead of the front, breezy conditions are 

expected on Friday into Saturday, mainly over the Gulf waters and 

along the coast. This will lead to a moderate to high risk of rip 

currents over the weekend. The frontal boundary pushing into

northwestern portions of the CWA will also increase rain chances 

on Saturday into Saturday night (20-40%), primarily along and 

east of I-69E. The Storm Prediction Center had placed Deep South 

Texas in a Marginal Risk for severe weather earlier today, but 

have since pulled us out and we remain in a general thunderstorm 

risk. Will continue to monitor this for potential changes over the

next 24-36 hours. Sunday morning the front will wash out before 

passing through the region, thus temperatures will not be 

affected. 



Dry conditions are expected through the remainder of the forecast 

with temperatures remaining 5-10 degrees above normal through 

Tuesday. Another cold front is expected to push through the region 

late Tuesday/early Wendesday bringing a bit of a relief to the hot 

temperatures. This will be a dry front but temperatures on Wednesday 

and Thursday are only expected to reach near normal or possibly a few 

degrees below normal for this time a year.
