.SHORT TERM...
(Thursday through Friday)
Issued at 124 AM CDT Thu Jun 26 2025

Persistence continues to be the best rule of thumb weather wise,
at least during the short term as our region remains under weak
high pressure ridging aloft with the center of the ridge remaining
across the Ohio and Tenn Valleys. Will await diurnal heating for
the development of isolated to scattered storms today but the
difference today is that drier PWATs have moved into our region
from the east. PWATs near or below 1.5 inches encompasses most of
our region attm with the exception of our far SW zones and our
far eastern zones. As we go through the day, these two areas
should see the best storm coverage and therefore, is the dividing
line between isolated convection and scattered convection.

Likewise for Friday, higher PWATs should be across our far
northwest zones in advance of a weak upper level shear axis across
the Southern Plains and across our southeast half in advance of
an inverted upper level trough across the Southeast U.S. and this
is where we will place diurnally driven pops.

Concerning temperatures, did not stray far from NBM high temps
today and Friday and we should see just enough mixing down of
afternoon dewpoints a degree or two to keep Heat Advisory worthy
heat indices at bay. Still cannot rule out a few locations
meeting or exceeding the 105 degree threshold but widespread
critical indices are not likely across our region through at least
Friday.

.LONG TERM...
(Friday Night through Thursday)
Issued at 124 AM CDT Thu Jun 26 2025

For the upcoming weekend, downstream ridging weakens and appears
to relocate across our region of the country albeit in a very weak
state. This ridge tries to very slowly retrograde westward in the
early and middle part of next week and that would introduce weak,
upper forcing to the north and east of this ridge axis. The end
result would be increasing rain chances, especially in the Tue-Thu
timeframe.

For now, will follow the NBM`s lead of gradually increasing pops
through the end of the Long Term as this trend is highly dependent
on the retrograding ridge. Did not stray far from NBM temps but
higher rain chances mid to late next week would obviously play a
hand in tempering temperatures which would buck the NBM`s
temperature trend next week.

.AVIATION...
(12Z TAFS)
Issued at 641 AM CDT Thu Jun 26 2025

For the ArkLaTex terminals, fair to partly cloudy this morning
with no BR. Winds will start off calm or VRB03KT and will soon
prevail S/SW for much of the day 5-10KT. Upper level low over FL
rolling in the easterlies, on approach may clip KMLU/KELD late
today. Closer in to this upper low, most of our terminals will
see late convection pulsing each day through the weekend. Then a
weak cold front will bottle up all the activity early next week.
In this heat the downpours will gust the winds every time. /24/

.SPOTTER INFORMATION STATEMENT...
Issued at 124 AM CDT Thu Jun 26 2025

While diurnally driven convection will likely result in thunderstorms
capable of producing strong wind gusts, the need for Spotter
activation resulting from widespread severe thunderstorms is not
likely through tonight.
