.SHORT TERM...
(Through tonight )
Issued at 1247 PM CDT Sat Jul 19 2025

Broad upper-level ridging continues to expand and strengthen over
the region. A hot and humid summer day has already unfolded across
the forecast area, with temperatures currently in the upper 80s and
lower 90s, with heat index values approaching or reaching triple
digits for several areas. A Heat Advisory remains in effect for most
of eastern OK and west-central AR until 8 PM this evening. Be sure
to take frequent breaks and stay hydrated if spending extended
periods of time outdoors through the rest of the afternoon.

A weak area of low pressure across the central Plains will keep
southerly winds somewhat elevated (5-10 mph) tonight. Wind speeds
should be strong enough to prevent any fog from developing, or at
least sustaining, overnight.  The presence of the ridge and
southerly winds will also keep temperatures on the mild side,
bottoming out in the mid-upper 70s.

.LONG TERM...
(Tomorrow through Saturday)
Issued at 1247 PM CDT Sat Jul 19 2025

The overall synoptic pattern doesn`t really change too much through
the long-term period. Upper-level ridging will continue to shift
closer to the area and strengthen next week, maintaining hot
temperatures and rain-free weather. Anticipate daily high
temperatures in the mid-upper 90s, to near 100 degrees and heat
index values between 100 and 110 degrees each afternoon, with
nighttime lows in the mid-upper 70s.

Another Heat Advisory has been issued for tomorrow (Sunday) for most
of the forecast area from noon until 8 PM. Benton, Carroll,
Washington, and Madison counties in AR should stay just below
advisory criteria, but some or all of these counties may need to be
added in the next forecast update if temperatures trend any warmer.
Regardless if in the advisory or not, its going to be unseasonably
hot through the entire forecast period and it will be imperative to
keep cool and hydrated if spending a prolonged period outdoors
during the daytime. Additional heat headlines are likely to continue
through next week.

(00Z TAFS)
Issued at 639 PM CDT Sat Jul 19 2025

VFR conditions expected all sites through the forecast period with
mid/upper level ridge over the region. Surface low over the Central
High Plains has resulted in a strong pressure gradient across the
Southern Plains, which will keep wind from decoupling entirely most
places tonight. Wind becomes gusty by mid morning Sunday most sites,
with gusts to near 20 kt possible. Strong low level jet overnight
will result in LLWS nern OK sites 06-14z.
