Updated at 628 AM CDT Sat Oct 11 2025

for much of next week.

    fire weather concerns for the weekend, especially Sunday
    afternoon.

  - Low Rain chances return early next week, mainly for areas
    along and north of I-44.

.SHORT TERM...
(Today)
Issued at 1213 AM CDT Sat Oct 11 2025

Cluster of showers earlier this afternoon produced a swath of 0.25"-
0.50" rainfall totals from BVO-TUL. This has resulted in patchy fog
along and west of Highway 75, which most likely will persist into
early morning with local reductions to 1/2 mile or lower. Otherwise
quiet conditions overnight with lows mainly upper 50s and lower 60s.

South winds will begin to increase to a degree across eastern OK
this afternoon under an expanding upper ridge. Temperatures will
once again warm well above normal with highs in the 80s, to around
90 west of Highway 75.

.LONG TERM...
(Tonight through Friday)
Issued at 1213 AM CDT Sat Oct 11 2025

Further strengthening of the sfc pressure gradient anticipated
Sunday as shortwave trough moves into the Northern Plains and
flattens the upper ridge. With continued well above normal
temperatures, likely a degree or two warmer than Saturday, fire
weather conditions will worsen as RH falls into the 25-35% range in
much of eastern OK. The area of highest concern will be where these
conditions overlap with a corridor extending from the west side of
Tulsa metro and south of US 412 that remains several weeks separated
from the most recent wetting rainfall.

A weak frontal boundary will approach from the north Monday while a
surge of tropical Pacific moisture moves over the plains. The latest
trends favor less of a frontal push south with the corridor of
associated rainfall mainly affecting areas to the northwest of the
forecast area. Rain chances Monday remain confined to areas
northwest of I-44 with generally light amounts anticipated at this
time. Temperatures will be slightly cooler Monday owing more to
increased cloud cover versus an actual airmass change.

Strong upper ridge expected to re-expand back over the Southern
Plains by the middle of next week with a return right back to summer
like conditions through Friday at least.

Light winds and a moist ground from showers yesterday afternoon
has left some light fog at daybreak at KBVO with some fog also
observed at KFYV. Outside of these temporary restrictions, VFR
conditions are expected through the TAF period. Winds will remain
light through much of the day then turn southeast and strengthen
as the pressure gradient increases in response to lee troughing.
