.SHORT TERM...
(Tonight through Saturday night)
Issued at 104 PM CDT Fri Jun 20 2025

Key Message:

- Low chances for isolated showers and storms today and Saturday.

Mid-level high pressure will continue to shift east through the
weekend, leaving South Central Texas on the western edge of this
ridge. Weak disturbances along with high precipitable water values
have allowed for isolated showers and a few thunderstorms to develop
this morning and early afternoon, mainly over the coastal plains.
Isolated activity may develop further west this afternoon. Gusty
southeast wind continues in the west decreasing later this evening.
Any showers or thunderstorms will also end early this evening with
the loss of daytime heating. Mostly cloudy conditions with lows in
the 70s are expected again tonight.

Another day of isolated showers and thunderstorms is expected for
Saturday, with models mainly focused over the western two-thirds of
the area for these rain chances. Further east, PWATs lower on
Saturday which could be contributed to some Saharan dust moving over
eastern Texas. Expect slightly cooler temperatures in the west
tomorrow as cloud cover lingers longest there. Highs may peak in the
upper 80s over portions of the southern Edwards Plateau and Hill
Country with the low to mid 90s elsewhere.

.LONG TERM...
(Sunday through Friday)
Issued at 104 PM CDT Fri Jun 20 2025

Key Messages:

- Near normal highs with above normal low temperatures through the
period.

- Low rain chances continue next week, mainly over the coastal
plains.

A dominant ridge will remain over the eastern US next week with
troughing over the western US. Sunday looks to be drier, but low
precipitation chances quickly return to the forecast each day next
week, mainly for the coastal plains eventually moving into the the I-
35 corridor mid to late week. This is mainly due to persistent
southeasterly flow bringing in moist, Gulf air combined with daytime
heating and possibly some weak mid-level disturbances. Highs will
generally be in the low to mid 90s for the week except along the Rio
Grande where the upper 90s to temperatures up to 102 degrees are
forecast. Overnight lows will mainly be in the 70s.

.AVIATION...
(00Z TAFS)
Issued at 631 PM CDT Fri Jun 20 2025

VFR flight conditions with gusty southeasterly winds should continue
for the next couple of hours before tapering off after sunset and
into the overnight hours for all sites except KDRT. For KDRT Winds
should decouple by 02Z before once again becoming gusty by 09Z. For
I-35 sites expect a period of MVFR conditions overnight and returning
to VFR by early morning with areas of SCT expected, much like we saw
today. For KDRT MVFR conditions are forecast to clear up by late
morning with gusty winds remaining throughout the afternoon.
