.DISCUSSION...
Issued at 159 PM CDT Wed Jul 30 2025

Coverage of showers and thunderstorms is doing better than this
time yesterday with lots of daytime heating left to go with
movement from NE to SW across much of our Four-State area.
Speaking of heating, we are seeing more than just isolated heat
indices over 110. Therefore with current obs reflecting such and
added compressional heating expected on Thursday ahead of the
cold front, this upgrade continues through early Thursday evening.
It is likely the following 24 hour period will see some relief
from the heat with another partial heat advisory likely into
Friday as the cold front arrives midday across our northern
fringe.

All the while, the PoPs will continue to increase in coverage
with multiple rounds of activity likely to continue through the
daylight hours on Friday and Saturday for our southern half. The
SPC continues a General Risk into the weekend, but with this kind
of heating, gusty winds to severe levels may show up at a few
more ASOS sites in the next day or two. So we will look to see
better temperatures, much closer to averages or even below for
this coming weekend. The NBM numbers will be nice to see, if only
for a couple of days. For now this brutal summer continues as the
cold front is slowly edging across the plains at this time. So if
thunder roars, go indoors as these storms will sport that late
summertime easterlies component of enhancement against the grain
so to speak. Rain cooled air falling into this extreme heat can
add a booster shot to the mix of gusts, especially if any dry air
aloft is utilized.

Our 18Z sounding has our PWAT getting back toward 2 inches and
the DCAPE remains over 1000, which is down a bit from yesterday.
We had a lot of sinking air under much cirrus this morning
inhibiting the cu field, but as mentioned we are already seeing
an uptick in convective activity from this time yesterday. We
will hang to some decent PoPs through the weekend and into early
next week, before the heat dome resumes it`s position over the
midSouth. So while August gets a brief break in the heat, the heat
advisory criteria will return by the middle of next week. All
right ahead of back to school timeframe here in our Four-State
area. Also, to note as we edge into Cape Verde season, the NHC is
not expecting anything to spin up in the next 7 days. /24/

.AVIATION...
(18Z TAFS)
Issued at 101 PM CDT Wed Jul 30 2025

Late cu field is starting to increase quickly across mainly the
eastern half of our airspace but cu is trying to fill in across
our western half as well. Also seeing some isolated storms pop
across our eastern and far northern airspace as well. As we go
through the remainder of the day and into the evening, storm
coverage probably warrants a VCTS mention across all our terminal
locations with the exception of the TYR terminal. Kept this going
through 03z, after which we should be left over with just some
cirrus and debris AC scattered to broken decks. Added the
possibility of a brief window of MVFR VSBY restrictions at the
LFK terminal near sunrise on Thursday but otherwise, VFR
conditions will continue outside thunderstorms this
afternoon/early evening.
