The main concern overnight is the impact of the wind shift
following the cold frontal passage on any ongoing fire fighting
efforts across northeast Oklahoma. The wind shift should begin to
impact Osage County around midnight, spreading to I-44 by 2 am.
Although wind speeds and gusts have decreased significantly from
this afternoon, occasional gusts near 25 mph will still be
possible near the Kansas border this evening, with the frequency
of such increasing behind the cold front. Relative humidities
remain low this evening and should not notably improve until
after the frontal passage. A Fire Danger Statement has been issued
to address these concerns. The overall forecast remains well in
hand and no additional product updates are planned this evening.

.LONG TERM...
(Tomorrow through Friday)
Issued at 159 PM CDT Fri Mar 31 2023

The strong upper level low responsible for today's severe/fire
weather will continue to move off to the east toward the Great
Lakes region Saturday. Surface high settles over the area with
lighter winds and cooler temperatures for the weekend. South
winds return on Sunday with only limited moisture return resulting
in some deterioration in fire weather conditions, though
certainly not to present extent. By later Sunday a disturbance off
S. California will be picked up in zonal flow and bring a chance
of showers and thunderstorms mainly S of I-40 during the
afternoon/evening. There are signals in the data that a cluster of
strong/severe storms moving near the Red River Valley during that
time.

By early next week another powerful upper level low is forecast
to move onshore and eventually eject into the plains by around
Tuesday. All indications point to another significant storm system
with both severe weather and fire weather concerns ramping up for
next Tuesday, with threats being de-lineated by eventual position
of dry line.

Behind that system it does appear a stretch of relatively quiet
weather with below normal temperatures will persist from mid to
late next week, with low rain chances possible mainly for
southern areas.
