.SHORT TERM...
(Through tonight)
Issued at 115 PM CDT Mon Aug 24 2026

The scattered showers and thunderstorms around the region this
morning have largely dissipated and shifted east with the
departing mid level wave. Surface analysis shows a weak frontal
boundary hanging out around northern Oklahoma extending westward
into west central Oklahoma as a surface low becomes centered over
central Oklahoma. Another weak mid level disturbance is also noted
on water vapor imagery moving across southern Kansas toward the
local region around the periphery of the stubborn upper ridge. Hot
conditions persist, especially south of the weak boundary, where
a Heat Advisory continues this afternoon. Persistent showery
conditions and cloud cover have kept temperatures in check for the
most part across the north and east, so will run with the current
configuration of the advisory for now, while monitoring trends.

Later this afternoon and evening, low shower and thunderstorm
chances will develop again across eastern Oklahoma into western
Arkansas along the stalled frontal boundary and in response to
the approaching vort max. Severe weather is not expected with this
activity, but a few stronger storms could develop, with locally
damaging wind gusts the main threat. Any storms that do develop
will likely wane into the overnight hours as the influence of the
mid level wave exits the area, though a few showers could linger
across portions of southeast Oklahoma.

.LONG TERM...
(Tomorrow through Monday)
Issued at 115 PM CDT Mon Aug 24 2026

A lull in activity is expected through much of Tuesday, with
overall warmer conditions areawide anticipated. The frontal
boundary will lose some of its definition by Tuesday afternoon,
but a small temperature gradient will exist form north to south
across the frontal zone. Temperatures in the triple digits can be
expected from I-40 south, with upper 90s more common across the
north. Have opted to catch the low hanging fruit with a Heat
Advisory for tomorrow south of the boundary. Will hold off
issuance for now across the north with more uncertainty in
boundary influences for those locations. The advisory may need to
be extended further north with later forecast packages. Potentially
more active weather returns by Tuesday night into Wednesday. A
more potent mid level shortwave will drop southeast out of the
High Plains. A complex of thunderstorms is forecast to develop
well northwest of the forecast area Tuesday evening and track
southeastward through the night Tuesday. This complex may reach
portions of northeastern Oklahoma early Wednesday morning.
Additional showers and storms will be possible during the day
Wednesday, with focus shifting south and east with time as the
vort max moves across the region. A reinforcing shot of cooler low
level temperatures will also arrive in the wake of this system
with more normal temperatures expected Wednesday into Thursday.

Upper ridging is forecast to become more centered over the
Southern Plains as we head into the weekend. This will bring
another period of hot and dry weather over much of the area.
Temperatures will trend back well above normal, with little in the
way of rain chances through the last half of the forecast period.

(00Z TAFS)
Issued at 557 PM CDT Mon Aug 24 2026

VFR conditions should prevail through the period, with perhaps
brief reductions in visibility due to the ongoing showers. Given
the low chance of on-station impacts from such, will keep the VCSH
mention at the W AR terminals and also add them to the NE OK sites
for the first 2 to 3 hours of the period. Gusty winds at the E OK
sites may linger past 00Z, with a downward trend by mid evening.
MLC should see a period of gusty southwesterly winds beginning by
mid morning and continuing until the surface boundary pushes
through the site mid to late afternoon.
