.SHORT TERM...
(Today through Sunday)
Issued at 141 AM CDT Sat Jun 7 2025

Key Message:

- Hot and humid conditions today and Sunday could result in Heat
  Advisories for parts of South Central Texas.

Regional satellite imagery shows the center of a 594dm Subtropical
Ridge over south Texas. This ridge will build northward today
through Sunday, leading to hot and humid conditions across all of
South Central Texas. Afternoon highs in the mid to upper 90s outside
of the Rio Grande Plains, and highs in the 100-108 range over the
Rio Grande Plains. Factoring in dewpoints in the upper 60s to mid
70s, it`ll feel like between 103-113 at times, particularly on
Sunday. Fortunately, we won`t have to wait long for relief, as rain
chances increase in the long term period.

.LONG TERM...
(Sunday night through Friday)
Issued at 141 AM CDT Sat Jun 7 2025

Key messages:

- Heat Advisory possible for parts of the area Monday

- Rounds of showers and thunderstorms Monday Through Friday

The Subtropical Ridge drifts to the southwest as the lower level
thermal ridge weakens slightly by Monday. While temperatures and
heat index values decrease slightly most areas, Heat Advisory level
heat index values remain closer to the Coastal Plains and across the
Winter Garden. Thus, a Heat Advisory is possible for those areas. An
outflow boundary from storms over northern Texas may move into the
Edwards Plateau, Hill Country, and our Central Texas counties late
Sunday night into Monday. This could generate isolated showers and
thunderstorms there. This would also provide some extra "cooling"
Monday afternoon there.

Short-waves rotating around an upper level trough and surface
boundaries from convection interacting with a moist airmass maintain
chances for rounds of showers and thunderstorms Monday night through
Friday. The greatest chances are Tuesday night through Thursday as
the upper level trough moves over the southern Plains. Moderate
instability indicates a potential for a few strong to severe storms.
An unseasonably moist airmass with moisture pooling along the
boundaries and cells repeating over the same areas or moving slowly
also indicate a potential for heavy rains. With heavy rains and some
flooding of late, runoff should be more rapid making for an
increased flooding threat. The heaviest rains are expected Tuesday
night through Thursday. Expect POPs to be fine tuned as mesoscale
influences take hold. The increased clouds and periods of rain "cool"
off temperatures to near average with below average highs possible
mid week.
