.NEAR TERM...
(Through Monday)
Issued at 245 AM CDT Mon Oct 5 2026

A cool, Autumn morning is ongoing across Oklahoma and north Texas
with light winds, clear skies, and temperatures in the 50s and
60s deg F. Temperatures will continue to lower before sunrise
with the potential for low-lying or sheltered areas in northern
Oklahoma dropping into the upper 40s deg F.

Plentiful sunshine and dry conditions are expected today
following the departure of the upper-level trough that affected
the region the last two days. With abundant sunshine this
afternoon, temperatures will rise into the upper 70s (northeast)
to the mid 80s (southwest). The coolest weather will be across
north central Oklahoma, which will be in closer proximity to the
surface high in the Midwest.

.SHORT TERM...
(Monday night through Wednesday night)
Issued at 245 AM CDT Mon Oct 5 2026

A warming trend is expected Tuesday and Wednesday afternoons with
a strengthening low-level thermal ridge and the return to
southerly winds across the Southern Plains. Oklahoma and north
Texas will be on the southeast edge of an elongated ~585 to 586
dam subtropical ridge. High temperatures will generally be in the
80s deg F with western north Texas into southwest Oklahoma in the
low 90s deg F by Wednesday. These temperatures will be ~7 to 10
deg F above-normal for early October. Dry conditions will
continue.

.LONG TERM...
(Thursday through Sunday)
Issued at 245 AM CDT Mon Oct 5 2026

Warm, above-normal temperatures and generally dry conditions will
continue through next weekend. There remains high confidence that
no significant cool down will occur, as indicated by minimal
spread in bias-corrected probabilistic guidance through Sunday.
Highs are forecast to remain in the 80s to low 90s deg F. There
is only a low chance (15%) of showers/storms Friday across parts
of western north Texas in association with an upper-level low in
Texas.

There are some signs of a potential pattern change by early next
week (October 13-15) among deterministic models and some ensemble
members, which could drive a cold front southward into the
Plains. As a result, the temperature spread increases markedly
(~30 deg F) in probabilistic guidance with the potential for an
appreciable cold front passage. Currently, there is a 20% (south)
to 50% (north) chance of high temperatures below 75 deg F on
Tuesday, October 13.
