.SHORT TERM...
(This evening through Friday)
Issued at 347 PM CDT Thu Aug 1 2024
Heat will remain the primary sensible concern for most, though the
probability of scattered thunderstorms continues to increase for
portions of northern Oklahoma this evening/tonight. While the upper
ridge axis has retrograded some today, a combination of mesoscale
factors: low-level thermal ridge axis expanding across the area,
pre-frontal compressional warming/"torching" and moisture pooling
in vicinity of a weak front has promoted a corridor of
>110-degree heat indices across western-central into northern
Oklahoma. In addition, as surface winds are weak near the front,
wet-bulb globe temperature risk is 'extreme' across much of this
area. Accordingly, an Excessive Heat Warning continues here until
9 PM this evening. Heat indices (and ambient temperatures across
southwest Oklahoma/north Texas) of >105-degrees are expected
elsewhere, where a Heat Advisory also continues through 9 PM.
The probability of scattered thunderstorms continues to increase
(now 30-40%) in vicinity of the surface front this evening. Given
the current location of the front, from ~Arnett-to-Red Rock, the
northern one-third of the forecast area is favored for
thunderstorms through early Friday morning. An environment
characterized by weak (15-25 knots) deep-layer shear should
promote generally disorganized (single/multi-cell) storm modes
this evening. Still, amidst a hot and dry (well-mixed) boundary
layer, a few severe-caliber (60-80 mph) downburst events are
likely with stronger storms through sunset. Any concern for severe
weather should diminish shortly after sunset, though gusty winds
and perhaps a few instances of small hail are possible through
daybreak Friday across northern/north-central Oklahoma.
Friday will represent a transitional day of sensible impact, with a
bifurcation of heat across the area (warmer south). The weak
frontal boundary will continue to slowly drop south, towards the
Red River Valley, through the day. Local compressional warming
will again foster a corridor of locally higher ambient
temperatures (>105-degrees) across the southern one-half of the
forecast area. This necessitates another day with a Heat Advisory
(from 1-8 PM) here. Further north, a "cooler" afternoon (high
temperatures in the upper-90s with lower humidity) is expected.
A corridor of scattered rain showers and thunderstorms may
ultimately continue in vicinity of the front through the
afternoon on Friday across central Oklahoma, though
predictability/probability remains low (20-30%), especially after
the mid-morning hours. Additional, diurnally-driven, scattered
convective chances are also possible near and south of the Red
River Friday evening. Severe weather concern is low on Friday.

.LONG TERM...
(Friday night through next Wednesday)
Issued at 347 PM CDT Thu Aug 1 2024
Heat concern will escalate into next week, with no evident sign
of precipitation beyond early Saturday morning. Warm/seasonable
weather is likely this weekend in the wake of the frontal passage.
While triple-digit heat is likely both days, drier conditions
behind the front will prove key to help avoid widespread
>105-degree heat indices and heat headlines (though small/targeted
coverage cannot be discounted). Ensemble/cluster data show (with
high confidence) a western CONUS upper ridge expanding eastward
early next week. This will foster a return of widespread triple-
digit heat and likely heat headlines.
Outside of a low chance (10-20%) for showers and a storm early
Saturday morning across southwest Oklahoma/north Texas, the extended
period looks to feature mostly dry weather.

.AVIATION...
(06Z TAFS)
Issued at 1106 PM CDT Thu Aug 1 2024
Scattered showers and thunderstorms are expected across northern
into central Oklahoma tonight into tomorrow morning. The most
likely terminals to see storms are KPNC, KSWO, KOKC, and KOUN.
Brief reductions in visibility, small hail, and gusty winds are
possible in the most intense storms.
A weak wind shift will slowly move southward tonight into
tomorrow morning. Winds will shift from the south to northeast or
east-northeast behind the boundary. Additional storms may develop
near the boundary tomorrow afternoon, but the probability is too
low to include in the TAFs.
