.SHORT TERM...
(Today through Wednesday)
Issued at 125 AM CDT Tue Jun 9 2026

Increasing clouds build overnight with warm lows around the mid 70s
by sunrise. A few showers may develop this morning, mostly favored
out west where wind in the low levels remains strongest. Later
today, conditions are generally expected to be drier than the over-
preforming showers and storms of yesterday. This afternoon, some
seabreeze showers or storms may again develop but activity should
remain isolated and limited to mainly the coastal plains. Morning
cloud cover will break up in the afternoon with highs in the upper
80s to mid 90s. Any shower or storm activity will diminish with the
sunset. Lows tonight and highs Wednesday will be similar to those of
today, with some slightly more breezy conditions expected Wednesday
afternoon.

.LONG TERM...
(Wednesday night through Monday)
Issued at 125 AM CDT Tue Jun 9 2026

Expect mainly hot and dry conditions late week with the exception of
any seabreeze showers or thunderstorms in the afternoons/evenings
over the Coastal Plains. The subtropical ridge will suppress
widespread precipitation development during this time, but this
feature does weaken as we head into the weekend due to broad
troughing amplifying over the central and eastern US. Moisture
increases over the area again late this weekend as ridging breaks
down bringing slightly higher rain chances Sunday and Monday.

Conditions will likely continue to feel humid late week due to high
soil moisture. With widespread highs in the 90s each day late week
into the weekend, heat index values may reach as high as 105-110
degrees at times depending on the location. We`ll mainly see cloudy
mornings with some clearing of skies in the afternoons. This pattern
keeps low temperatures slightly above normal each night contributing
to moderate heat risk over much of the area during the long term
period.

.AVIATION...
(12Z TAFS)
Issued at 548 AM CDT Tue Jun 9 2026

Ceilings are mostly MVFR with intermittent IFR in the San Antonio
area. All terminals will return to VFR by around noon. There is
around a 20% chance for showers or thunderstorms during the
afternoon, but the probability is too low to include in the TAFs.
Low ceilings will develop again late tonight.
