- Mostly dry weather with above normal temperatures this week.

.SHORT TERM...
(Through tonight )
Issued at 1126 AM CDT Tue Sep 30 2025
An upper level low passing across the area will contribute to
partly to mostly cloudy conditions through this evening. Most of
the moisture is centered at or above 600 hPa, with much drier air
below that, so areas of virga showers or sprinkles are possible,
but measurable rain at the surface is unlikely. High temperatures
will peak in the low to mid 80s. Skies will clear out this
evening allowing for somewhat cooler temperatures overnight,
generally in the mid 50s to low 60s.

.LONG TERM...
(Wednesday through Tuesday)
Issued at 1126 AM CDT Tue Sep 30 2025
Upper level ridging rebuilds across the area Wednesday,
strengthening into Friday. This will allow for temperatures to
rebound slightly. A few areas may reach 90 F in eastern Oklahoma
Thursday to Friday, with mid to upper 80s elsewhere. A transient and
weak upper level wave will brush the area Thursday, with perhaps a
couple of afternoon showers in the higher terrain of northwest
Arkansas, but otherwise dry conditions are anticipated.
Upper level ridging retreats slightly over the weekend as a system
impinges on the area from the southwest. But as it never really gets
very close, dry conditions will most likely persist. If models
trended closer with the system, we could introduce a slight chance
of showers across eastern OK, but for now this seems unlikely. Lower
level thermal profiles only cool slightly, so temperatures may drop
a couple of degrees, but will remain well above normal for this time
of year.
Towards the end of the forecast period ensemble guidance diverges. A
large subset of guidance shows a continuation of the current regime.
A smaller subset allows a trough to finally push into the area
bringing cooler conditions as well as a chance of rain showers.
Mostly leaned towards the warmer solution, but at least hinted at
the potential pattern shift towards day 7.
