  northern Burnet and Llano Counties.

- Increasingly hot and dry weather expected Tuesday-Friday.

.SHORT TERM...
(Tonight through Monday night)
Issued at 1207 PM CDT Sun Aug 3 2025

Northwesterly flow aloft continues today but without any mid-level
forcing for afternoon convection, the threat for rain and storms is
low (less than 10%). Expect a seasonably hot afternoon with highs in
the upper 90s to lower 100s.

Another chance at showers and storms arrives with a shortwave
disturbance rounding the eastern periphery of the subtropical ridge
to our west. Some morning convection appears possible given the
latest 12Z CAMs, and PoPs were expanded compared to what the NBM
populated. PoPs are expected to linger into the afternoon and evening
hours, with some locally heavy rainfall possible once again,
primarily along and east of I-35. Our area is not outlooked for any
excessive rainfall by WPC and most storms should be more transient in
nature than the convection we`ve seen the last couple days. Storms
may linger through late Monday evening before weakening after sunset.

.LONG TERM...
(Tuesday through Sunday)
Issued at 1207 PM CDT Sun Aug 3 2025

For the most part, the long term period looks hot and dry with the
exception being over the Coastal Plains, where seabreeze showers and
storms are possible, particularly on Tuesday when the ridge hasn`t
gotten a firm hold of our region yet. By Wednesday and beyond, hot
and dry conditions are expected with just a few showers possible over
southern Lavaca and DeWitt counties each afternoon. Highs will climb
into the upper 90s to around 100 each day, with mornings in the 70s.
There are some signs that the ridge may break down and push back west
by the weekend, opening the door for north to northwest flow again,
but there is some disagreement among medium range guidance on this
solution.

.AVIATION...
(00Z TAFS)
Issued at 629 PM CDT Sun Aug 3 2025

Mainly VFR conditions through tonight and Monday. Isolated to
scattered SHRA/TSRA activity is forecast Monday afternoon through
portions of the eastern Hill Country, I-35 corridor, and Coastal
Plains, although timing and exact placement is low confidence.
Therefore, continuing with PROB30 TSRA at AUS for large timing
window Monday afternoon, and have also included in the SAT/SSF TAFs.
Gusty wind speeds and erratic directions are expected in TSRA
activity and behind associated outflow boundaries.
