Issued at 1043 PM CDT Mon Sep 22 2025
The combination of abundant moisture, daytime heating and the
approach of a cold front will maintain unsettled weather across Deep
South Texas through the period. Isolated to scattered showers and
thunderstorms will be possible Tuesday and Wednesday. A cold front
will move into central Texas on Wednesday. The best rain chances
look to be on Thursday as moisture pools (PWATs 2"+) along and ahead
of the cold front. There is a medium (40-70%) chance of showers and
thunderstorms on Thursday. There some uncertainty if the frontal
boundary will push through Deep South Texas or stall over or north
of the region. There is a low to medium (20 to 60%) chance of rain
Thursday night into Friday, especially if the front stalls across
the area. Any showers or thunderstorms that develop have the
potential to produce locally heavy rain that could lead to nuisance
flooding, especially on roadways and low lying areas. Rain chances
will continue into the weekend into early next week.
Hot and humid conditions will continue through midweek with near to
slightly above normal temperatures. The Heat Risk will be Moderate
(level 2 out of 4) to Major (level 3 out of 4) Tuesday and
Wednesday. Heat indices between 105 to 110 degrees will be likely
Tuesday and Wednesday with some locations briefly reaching around 112
degrees. However, heat indices Tuesday and Wednesday are expected to
remain below Heat Advisory criteria advisory. The combination
abundant cloud cover, increasing rain chances and a possible weak
cold front in the area may lead to slightly below normal
temperatures late this week and into the weekend. The Heat Risk will
drop to Minor (level 1 out of 4) Friday through Monday.
