.SHORT TERM...
(Tonight through Thursday night)
Issued at 1234 PM CDT Wed Jul 2 2025

There are notably lower precipitation chances for this afternoon
and evening across Deep South Texas, with around 20-40% chance as
remnant tropical moisture interacts with diurnal instability.
Surface high pressure and mid level ridging begin to build
overhead, and subsidence associated with this feature will bring
an end to our unsettled weather period. While some activity may
develop tomorrow afternoon along the sea breeze, for the most part
most of the region should remain-rain free after this evening.

Our attention will then turn to the return of seasonable heat for
early July, with highs in the low 90s returning tomorrow
afternoon. In combination with lingering moisture, heat index
values will range from 100 to 108 degrees. As many begin the
holiday festivities tomorrow, remember to practice heat safety to
prevent any heat-related illnesses.

.LONG TERM...
(Friday through next Wednesday)
Issued at 1234 PM CDT Wed Jul 2 2025

The 4th of July holiday and weekend will feature generally rain-
free conditions and near to slightly above normal temperatures for
early July as the region remains under the influence of ridging
aloft. High temperatures Friday through Sunday will range from the
mid 80s along the Lower Texas beaches to mid/upper 90s further
inland. In combination with the humidity, heat index values each
afternoon will range 100 to 108 degrees. There will be a minor
(level 1 of 4) to moderate (level 2 of 4) heat risk through the
weekend for across all Deep South Texas, which means the heat will
primarily affect those sensitive to the heat, as well as those
spending a prolonged period of time outdoors without adequate
cooling or hydration. Low rain chances (around 20% or less) return
early next week.
