(Today through Tuesday)
Issued at 1216 AM CDT Mon Jul 27 2026

Water vapor imagery and upper air observations show the subtropical
ridge commandeering our regional weather remains strong. Surface
high over the Gulf will move slightly west today under weak easterly
flow aloft. This brings a marginally more conducive wind direction
for hotter temperatures. Thus, highs today are expected to be about
1-2 degrees warmer with peak heat indices in the 101 to 107 range
over the Coastal and Rio Grande Plains and the I-35 corridor. Some
cirrus may uneventfully cycle over the area as the ridge continues
to spin about. No rain is forecast. Tuesday is expected be similarly
hot and dry. Conditions both days may briefly reach Heat Advisory
criteria for localized spots in the Coastal Plains, but at this time
the lower coverage and longevity of higher heat for Monday and
Tuesday suggests low confidence in Heat Advisory issuance for today
or tomorrow.

.LONG TERM...
(Tuesday night through Sunday)
Issued at 1216 AM CDT Mon Jul 27 2026

Hot and rain-free weather continues through the week with the
subtropical ridge staying near the area. Temperatures are forecast
to steadily rise as the airmass warms, with highs entering the 100-
105 range in more widespread fashion by late week. Heat indices may
climb more into the 105-110 range especially at lower elevations mid
to late week. This could necessitate issuance of heat related
products.

Hot and dry conditions may continue into Saturday, but a shift in
the weather pattern ushered by the ridging moving farther favors a
change in conditions over South Central Texas this weekend. As the
eastern periphery of the ridge lines up with the Plains, northerly
flow will be favored aloft. This may bring a weak front or trough
into our area this weekend, accompanied by rain chances and a
potential cooldown to below average temperatures towards the start
of August if the front remains intact.

.AVIATION...
(06Z TAFS)
Issued at 1216 AM CDT Mon Jul 27 2026

All terminals are starting VFR. Our overall weather pattern has
not changed significantly over the past 24 hours. We expect this
will result in a repeat of low ceilings tonight even though none
of the models are showing this. We have included MVFR ceilings in
the Austin and San Antonio areas starting in the next few hours
and lasting until late morning. DRT will remain VFR. All terminals
will be VFR through the afternoon and evening. MVFR ceilings will
redevelop after midnight Monday/Tuesday.
