Dangerous to record breaking heat will build across the center of the nation and slowly build eastward this week. Wildfire conditions remain critical for the Southwest and portions of the Great Basin through Monday. For the northern Plains and upper Midwest, severe thunderstorms with the potential for large to very large hail and severe winds are the primary hazards. Read More >

- Hot and seasonable temperatures continue through the Holiday
Weekend.
- Low shower and thunderstorm chances return late this weekend into
early next week.

.UPDATE...
Issued at 541 AM CDT Wed Jul 1 2026
Some streamer showers are showing good organization and a few
heavy echoes at times, so have opted to add a couple hours of Pops
nearby. New cells continue to form, so another reactive update may
be needed in another 30 minutes to an hour to add low chances for
showers to more areas.

.SHORT TERM...
(Today through Thursday)
Issued at 1234 AM CDT Wed Jul 1 2026
A 597dm High remains in control over the eastern CONUS, contributing
to record heat out east and continued dry weather here in south
central Texas. While some seabreeze shower activity cannot be ruled
out today and tomorrow, it`s more likely to be dry as capping and a
lack of forcing keep things in check. Temperatures will climb into
the mid to upper 90s both days with heat indices in the 100-106
range, typical for early July.

.LONG TERM...
(Thursday night through Tuesday)
Issued at 1234 AM CDT Wed Jul 1 2026
The ridge slowly starts to weaken and slide eastward closer to the
eastern seaboard, allowing flow aloft to weaken slightly and turn a
bit more northwesterly by the end of the Holiday weekend. Some low
end rain chances will return with this shift in the jet stream, but
it doesn`t look significant at this distance. After a hotter and
drier stretch the past 2 weeks, most would be welcoming to
additional rainfall during the start of the hottest month of Summer.

.AVIATION...
(12Z TAFS)
Issued at 541 AM CDT Wed Jul 1 2026
A few streamer showers have popped up east of SAT/SSF. Minimal
impacts are expected, but some of the downpours seen on radar
would suggest some MVFR or lower VSBYS should new ones pop up
closer to the VCNTYs. Broad but ragged coverage of MVFR CIGs
continue near all 4 TAF sites, and the plentiful breaks in
coverage should lead to rapid mixing and decreases in coverage
through 15Z. Similar speeds and directions are projected for the
winds over the next day, so we`d anticipate a persisence type of
forecast in the handling of the morning MVFR CIGs going forward.
