.SHORT TERM...
(Today through Saturday)
Issued at 1238 AM CDT Fri Jun 27 2025

The forecast for today and Saturday are similar in the short term
period. Increasing cloud cover will build over South Central Texas
early each morning with lows in the 70s. Low chances for isolated to
scattered shower and thunderstorm development remain each afternoon,
though are mainly confined to the coastal plains where precipitable
water values remain highest. Breezy conditions are expected each
afternoon and evening, with the highest gusts out west along the Rio
Grande.

.LONG TERM...
(Saturday night through Thursday)
Issued at 1238 AM CDT Fri Jun 27 2025

A surge of moisture and high precipitable water values moves over
the area on Sunday increasing precipitation chances that afternoon
from the coastal plains into the I-35 corridor. Models vary on how
much isolated to scattered shower or thunderstorm activity will take
place Sunday afternoon, but most guidance has at least some light
rainfall over these areas. Additionally on Sunday, a plume of
Saharan Air Layer (SAL) dust is forecast to move over inland Texas,
mainly from the Hill Country and areas east. This layer of dust is
expected to linger through the middle of next week before it shifts
east Thursday, though another plume of dust may move back over the
area by Friday. The main noticeable impacts of this will be a more
hazy, milky appearance to the sky during the day and slightly more
vibrant sunsets.

While drier conditions are generally expected next week aided by
this forecast layer of dust, low precipitation chances do remain in
the forecast mainly due to any seabreeze activity or thunderstorm
activity that moves in from the north. Temperatures each day remain
hot, mainly in the 90s. Along the Rio Grande, some locations may
reach into the triple digits Sunday into next week.
