.SHORT TERM...
(Today through Sunday)
Issued at 114 AM CDT Sat Jun 29 2024

Nocturnal low stratus continues to expand in coverage across South-
Central Texas overnight. Southeast winds are near 10-15 mph with
temperatures remaining in the lower 80s at the present hour. Should
see lows later this morning in the upper 70s to near 80 degrees.
Another hot end of June day is expected this afternoon with highs in
the upper 90s to near 103 degrees. Humid conditions will allow for
afternoon heat index values to max out near 108-112 degrees for
areas mainly east of the I35 corridor and a Heat Advisory remains in
effect for these locations today. Deep moisture could support a
stray shower in the Coastal Plains today, but overall chances were
too low to mention anything specific in the grids.

Another round of nocturnal stratus is expected tonight with lows
back in the upper 70s to near 80 degrees. For Sunday, low-level
winds remain more southeasterly through the day which may allow
temperatures to be a degree or two cooler in the afternoon. Will
still likely need a Heat Advisory for some portion of the area, but
the size of the area will likely be smaller compared to today`s
advisory.

.LONG TERM...
(Sunday night through Friday)
Issued at 114 AM CDT Sat Jun 29 2024

Subtropical Ridging will remain in control this weekend, and
actually expand further into our region by early next week, resulting
in our hottest area wide temperatures so far this Summer. Key words
there: so far. Heat headlines are expected to continue so as always,
be sure to avoid the heat if you can during peak heating, mainly
between the hours of 11am-4pm, and if you do plan on spending time
outdoors, apply plenty of sunscreen, where light, loose fitting
clothing, and hydrate, hydrate, hydrate. We may see a shower or two
work its way inland by way of the seabreeze on Wednesday afternoon,
but that would only be for portions of the Coastal Plains. Otherwise,
we will maintain the status quo, with hot and dry conditions, and
higher humidity along and east of the I-35 corridor.

You may be wondering about the tropics as well. Unfortunately, very
little moisture in the form of precipitation will be able to work
into our region due to the strength of the Subtropical Ridge, but
that could change by the time the end of next weekend rolls around.
We will just have to wait and see on how things play out over the
Atlantic with what looks to continue to be a very active season.

.AVIATION...
(18Z TAFS)
Issued at 1234 PM CDT Sat Jun 29 2024

Cloud bases have lifted and VFR conditions will continue through the
afternoon and evening. Gusty south to southeast winds will also
persist for all TAF sites. Some isolated showers are ongoing over the
coastal plains and radar trends and hi-res models suggest this
activity will stay east of the I-35 corridor. MVFR cigs will return
to the I-35 sites between 06-08Z and continue through late morning.
We have also added some MVFR cigs to DRT between 09-16Z based on
morning observations along with forecast soundings for Sunday
morning.
