.DISCUSSION...
Issued at 137 AM CDT Thu Aug 20 2026

High pressure will persist, with only slight shifts on the location
of the center. This will keep us hot and dry through the period. Our
only hope of rain will be seabreeze convection in the afternoons,
but chances of this are very low (<10%).

High temperatures will range from 90 along the coast to around 105
over the Brush Country. Heat index values will slowly increase to
110-114 by Friday, with isolated locations (mainly in the inland
Coastal Bend) reaching 115. For now, have not issued a Heat Advisory
for today, but we will need to watch and potentially issue a short-
fused Advisory. By Friday, expect Heat Advisories may be necessary
daily through the weekend. Take frequent breaks and remember to stay
hydrated, check those backseats, and avoid long exposure in these
temperatures. For more information be sure to check out
weather.gov/heatsafety.

.AVIATION...
(06Z TAFS)
Issued at 137 AM CDT Thu Aug 20 2026

Overall forecast remains generally unchanged with VFR conditions
expected through the TAF period, with only very low chances for
MVFR visibility at VCT and ALI. Winds will diminish overnight
before 20 knot gusts return Thursday afternoon.

&&

.MARINE...
Issued at 137 AM CDT Thu Aug 20 2026

Light to moderate (BF 2-4) onshore breezes will continue through the
period, with occasional fresh (BF 5) breezes possible during the
late afternoon/evening hours. Seas are expected to remain around 2-3
feet. Rain chances will remain near zero.

&&

.FIRE WEATHER...
Issued at 137 AM CDT Thu Aug 20 2026

The potential for elevated fire weather conditions over the Brush
Country and portions of the western Coastal Plains are expected to
continue into next week, with relative humidity values dropping into
mid 20s each afternoon. With ERC values in the 75-89th percentile,
low humidity, dry to critically dry fuels, and hot temperatures, a
few locations across the Brush Country could see critical fire
weather conditions today into next week.
