.SHORT TERM...
(Through tonight)
Issued at 1143 AM CST Wed Jan 14 2026

Fire weather concerns highlight the forecast this afternoon, with
strong and gusty northwesterly winds and relative humidities
expected to fall into the 25 to 35 percent range behind the cold
front. The weather conditions will lead to widespread elevated to
locally near critical grassland fire spread rates through the
afternoon, all in combination with the persistently dry
conditions. A Wind Advisory has also been issued for the rest of
the day, given multiple Oklahoma Mesonet and ASOS sites recording
near to above 40 mph gusts late this morning. Wind speeds will
trend downward through the evening as the surface ridge
approaches, with light west to southwesterly winds returning to
parts of the area by daybreak Thursday. With good radiating
conditions overnight, expect temperatures to be noticeably cooler,
including some teens in parts of far northeast Oklahoma and
northwest Arkansas.

.LONG TERM...
(Tomorrow through Wednesday)
Issued at 1143 AM CST Wed Jan 14 2026

With consistent northerly winds aloft, dry cold fronts remain
expected to move through the region every couple of days, with
gusty post-frontal winds signaling an uptick in fire weather
concerns. Friday remains likely to be one of these heightened fire
weather days, following a Thursday night cold frontal passage.
Northwesterly winds behind the front on Friday should be fairly
similar to today, with gusts near 40 mph especially along and
north of I-40. Afternoon relative humidities across much of
eastern Oklahoma will fall into the 20 to 30 percent range. Near
critical grassland fire spread rates are currently forecast west
of Highway 75 in northeast Oklahoma. Given the fuel states, a Red
Flag Warning may be necessary.

Another cold front will follow quickly on the heels of the
Thursday night/Friday one, set to move through Saturday with
another increase in northwesterly winds, continued low relative
humidities areawide and locally near critical fire weather
conditions possible. Below normal temperatures will prevail for
the weekend, despite a return to southwesterly winds on Sunday.

Yet another shot of cold air will move through the region Sunday
night and into Monday, with some model discrepancies regarding how
much of it will move into the area as opposed to a glancing blow
to the northeast.

Once we get toward the middle part of next week, more westerly
flow aloft looks to take hold, which would signal warmer
conditions.
