.NEAR TERM...
(Rest of today and tonight)
Issued at 141 PM CDT Wed Jul 23 2025

Other than seasonably hot and humid conditions, the potential for
widely scattered showers and thunderstorms will return across the
western two-thirds of the forecast area this afternoon and evening.

Multiple satellite channels capture a trio of mesoscale vortices
across the Plains early this afternoon, with the features
currently lifting northward near Haskell, TX and eastward across
the New Mexico/Texas border likely to influence precipitation
chance across our area over the coming hours. As heating begins to
maximize, coupled with the aforementioned features and weak
upper-level ascent, widely scattered convective development seems
plausible by ~3-4 PM.

Within a hot and well-mixed boundary layer (fostering steep lapse
rates), a few strong-to-severe thunderstorms will be possible with a
risk for damaging downburst wind gusts. While precipitation chance
will continue into the late evening, especially across northern
Oklahoma, thunderstorm intensity (and risk for strong wind) is
expected to wane concurrent with boundary layer stabilization.

Afternoon and evening temperatures look to run near seasonable
average (mid to upper-90s) across the area today. A few heat index
values nearing 105-degrees will be possible in the moisture axis
across south-central Oklahoma, though most locations should avoid
advisory-level conditions.

.SHORT TERM...
(Thursday through Friday night)
Issued at 141 PM CDT Wed Jul 23 2025

Dangerously hot and humid conditions will return for most of the
area by Thursday along with another afternoon and evening period of
shower/thunderstorm potential (especially north).

While the local upper air pattern looks to remain somewhat
nebulous on Thursday, more focused surface features are currently
anticipated to emerge by the afternoon. This includes an inverted
surface trough extending across portions of West Texas into
western Oklahoma, along with influence from a weak front across
northern Oklahoma. As another weak upper system advances eastward,
scattered afternoon and evening convection is again expected,
especially in vicinity of the aforementioned surface front. Once
again, with hot surface conditions and weak wind shear, multi-cell
thunderstorms with a risk for strong to severe wind gusts are
likely into the mid-evening.

Ambient temperatures look to escalate on Thursday in response to the
surface features discussed above. Triple-digit conditions are likely
from western-north Texas into portions of north-central Oklahoma.
Combined with a lingering moisture axis, especially with eastward
extent, >105-degree heat indices are likely for most locations
into the early evening. A Heat Advisory has been initiated for
most of the area from 1 PM to 8 PM on Thursday.

Thursday will likely be the beginning of a prolonged period with
heat headline potential, with dangerously hot conditions extending
into Friday (and beyond). While scattered rain showers and perhaps a
thunderstorm or two may be ongoing near daybreak Friday across
northern Oklahoma (tied to remnant activity from the prior evening),
daytime conditions appear likely to feature dry surface weather

.LONG TERM...
(Saturday through Tuesday)
Issued at 144 AM CDT Wed Jul 23 2025

The upper high "heat-dome" strengthens this weekend as well as
surface moisture with 70s dewpoints fairly widespread except perhaps
across northwest Oklahoma.  Will see dangerous heat & muggy
conditions with heat indices of 105 to exceeding 110 degrees this
weekend mainly in southeast Oklahoma where afternoon excessive heat
warnings may be needed. Our heatwave will continue into early next
week as the upper high builds further into the Central Plains &
Midwest.

.AVIATION...

Issued at 124 PM CDT Wed Jul 23 2025

VFR conditions are expected at all terminals through the period.
There is a low (around 30%) chance for thunderstorms across the
western and central terminals. Otherwise, southerly winds will
prevail through the period, veering slightly by tomorrow morning.
