.NEAR TERM...
(Through Monday night)
Issued at 210 AM CDT Mon Sep 8 2025
Weak isentropic ascent associated with a 30-knot 925 mb low-level
jet may result in scattered showers and thunderstorms toward
sunrise across northwest Oklahoma. Severe weather is not expected
with any activity that develops this morning. If convection
develops, it may persist across northwest Oklahoma/near the
Kansas border through much of the morning.
By late this afternoon, daytime heating along and ahead of a
diffuse dryline is forecast to be sufficient to remove any
convective inhibition for robust, surface-based convection across
southwest Kansas, the Texas/Oklahoma panhandles, and northwest
Oklahoma.
Scattered showers and thunderstorms are expected to develop and
move toward the south within the northwest flow aloft. Instability
(~1500 to 2000 J/kg of CAPE) and shear (effective bulk shear ~35
knots) will be sufficient for strong to severe thunderstorms.
Convective-allowing models indicate these thunderstorms may grow
into one or two clusters that will move southward across western
Oklahoma before weakening late evening with the loss of daytime
heating. The convection may make it as far south as western north
Texas as it weakens given a modest low-level jet. Damaging wind
gusts and hail will both be possible given the storm mode (i.e.,
clusters) and magnitude of vertical shear.

.SHORT TERM...
(Tuesday through Wednesday night)
Issued at 210 AM CDT Mon Sep 8 2025
Dry weather is expected during the day Tuesday. The eastern
fringe of an expanding low-level thermal ridge across western U.S.
will result in warmer weather Tuesday afternoon with highs in the
mid 80s to low 90s deg F.
There will be another chance of showers/storms Tuesday night into
Wednesday morning across northwest Oklahoma as remnant convection
from the north and a modest low-level jet may allow some
convection to sustain itself. Severe weather is not expected with
this activity.
By Wednesday, the mid-level ridge and associated low-level thermal
ridge will move farther eastward into the Plains. The mid-level
ridge is forecast to amplify and increase in magnitude. This will
result in warmer weather toward the middle and latter part of the
week with above-normal temperatures becoming more likely.

.LONG TERM...
(Thursday through Sunday)
Issued at 210 AM CDT Mon Sep 8 2025
The mid-level ridge is forecast to remain entrenched across the
Southern Plains through at least Saturday, which will likely
result in continued above-normal temperatures and minimal rain
chances.
The probabilistic temperature forecast (derived from an ensemble
of bias-corrected models) indicates a very high chance of above-
normal temperatures given even the 10th percentile (the colder
end of guidance) has slightly above-normal temperatures Thursday
through Saturday. High temperatures will likely range from the
upper 80s to mid 90s deg F.
By late Saturday into Sunday, the mid-level ridge may weaken as a
trough lifts into the Plains. As a result, there is at least a
low chance of showers and thunderstorms the second half of the
weekend.

.AVIATION...
(06Z TAFS)
Issued at 1052 PM CDT Sun Sep 7 2025
VFR skies continue for the next 24 hours. Winds tonight will
gradually shift toward southerly, then increase toward 10-15 knots
after daybreak tomorrow. Expecting one or several thunderstorms to
move south out of Kansas into northwest Oklahoma during the
afternoon/evening, with WWR and GAG having the highest odds of
being impacted by those storms.
