.SHORT TERM...
(Tonight through Thursday night)
Issued at 1251 PM CDT Wed Jul 30 2025

Today`s high temperatures are forecast to hit the lower 90s and up
to 102 along the southern part of the Rio Grande after a cool
morning in the 60s over many locations. Satellite images from the
visible, IR, and WV channels are showing high clouds (moisture)
spreading across the eastern half of the local area as an upper level
inverted trough axis moves across Louisiana. The upper level trough
is forecast to move from east to west for the rest of today into
Thursday. Increased moisture arrives to the local area as the trough
axis gets closer to east Texas and the upper level ridge that sits
over South Central Texas early this afternoon pushes to the west for
the next 24 hours. So, no rain expected for the rest of today with
heat index values at or below high temperature values due to a dry
air mass dominating the lower levels.

By Thursday afternoon, the upper level inverted trough moves across
the middle Texas coast and brings a slight chance for showers and
storms mainly over portions of the Coastal Plains. Humidity values
are forecast to increase resulting in dew points in the mid 60s to
lower 70s. Therefore, a top of having a hot day forecast for
Thursday with highs in the mid 90s to 101 and up to 103 across the
southern Rio Grande, the heat index values are forecast to range
from 100 to 105 over some locations across the Coastal Plains and
Rio Grande due to increased moisture.

.LONG TERM...
(Friday through Wednesday)
Issued at 1251 PM CDT Wed Jul 30 2025

Rain chances persist and spread across South Central Texas on Friday
into the first part of the weekend as the upper level inverted
trough moves across the local area. By Sunday, the upper level
trough pushes way to our west while the subtropical ridge builds
back into our area resulting in dry weather conditions. The next work
week looks dry with seasonable temperatures as we enter into the
month of August.

.AVIATION...
(18Z TAFS)
Issued at 1251 PM CDT Wed Jul 30 2025

Current visible satellite shows some high level clouds working into
the area from east to west as an inverted trough makes its way
towards the TX coast. Regardless, VFR cigs are expected at all TAF
sites throughout the forecast period. Southerly winds less then 10
kt are expected until late overnight when the trough approaches
causing winds to switch to the west/southwest through the remainder
of the TAF period for I-35 TAF sites. For KDRT winds will remain
east southeasterly through the period.
