.DISCUSSION...
Issued at 1042 PM CDT Sun Sep 21 2025
The combination of abundant moisture, a series of mid-level
disturbances and daytime heating will support low to moderate daily
shower and thunderstorms through the period. The best rain chances
look to be on Thursday as moisture pools (PWATs 2"+) along and ahead
of next cold front. There is some uncertainty if the frontal
boundary will push through Deep South Texas Thursday or stall over
or north of the region. 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.
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) Monday through
Wednesday. Heat indices between 105 to 110 degrees will be likely
Tuesday and Wednesday with some locations reaching near 112. Heat
Advisories may be needed Tuesday and Wednesday. The combination
increasing cloud cover, rain chances and the potential arrival of a
cold front may lead to slightly below normal temperatures by late
week. The Heat Risk will drop to Minor (level 1 out of 4) Friday
through Monday.

VFR is expected at the aerodromes through the next 24 hours. The
PROB30 has been removed, as model guidance now suggests a drier
forecast. However, a highly-isolated convective cell cannot be
entirely ruled out.

Light to moderate winds and generally low seas will prevail
through the period. There is a low to medium (20-60%) chance of

thunderstorms.
