.SHORT TERM...
(Today)
Issued at 257 AM CDT Wed Apr 5 2023

Strong cold front has moved into northeast Oklahoma early this
morning, currently located north of a Tulsa, Miami line. At this
time, storms remain elevated behind the front, limiting the tornado
potential. There remains a low chance that additional storms could
develop further south and reside in move favorable environment given
the strong instability/shear profiles. Regardless, some severe threat
will continue as storms move through the remainder of northeast
Oklahoma into northwest Arkansas with damaging wind/large hail
possible. Storms should shift east of the CWA by mid morning with
the severe threat ending.

Otherwise, gusty northwest winds at 25 to 30 mph will continue
this morning behind the cold front with highs only climbing to
around 60 across northeast Oklahoma. The gusty winds should
slowly subside this afternoon, however with a drier air-mass in
place, a limited fire weather threat is expected as RH values fall
into the 20 to 25 percent range north of I-44.

&&

.LONG TERM...
(Tonight through Tuesday)
Issued at 257 AM CDT Wed Apr 5 2023

Surface high pressure will build into the region tonight and with
light winds/clear skies, good radiation cooling is expected. Low
temperatures are forecast to fall to near or just below freezing
in a few locations across far northeast Oklahoma, near the OK/KS
state line. Given the freeze will not be widespread, no headlines
are anticipated at this time.

The cool weather will continue through the remainder of the work
week with mild/pleasant conditions for the Easter weekend as a slow
warming trend develops. Precipitation chances will remain minimal,
except for maybe a few showers over far southeast Oklahoma during
the day Friday.

Models in better agreement for the early part of next week as
surface ridge aloft develops over the southern Plains. Unseasonably
warm/breezy conditions expected with highs back into the lower to
mid 80s Tuesday/Wednesday.  Although low level moisture will begin
to slowly increase during this time, at least a limited fire weather
threat will be possible, especially in areas with ongoing drought
conditions.

.AVIATION...
(06Z TAFS)
Issued at 1221 AM CDT Wed Apr 5 2023

Mostly VFR cigs can be expected across the TAF sites, though a period
of MVFR cigs and vsbys in a period of TSRA that will accompany a cold
front that will move through tonight. Will use tempo groups given the
1-2 hour duration of TSRA. Behind the front, VFR elements will prevail for
the remainder of the valid period. Winds will shift to the W-NW
with gusts up to 25 kts expected for a few hours. Winds will relax
during the afternoon and become less than 10kts after 00z.

This Outlook is for Northwest and West Central Arkansas as well as
much of Eastern Oklahoma.

.DAY ONE...This Afternoon and Tonight.

	AREA...Southeast Oklahoma and Western Arkansas.
	ONSET...After 2 AM.

SEVERE THUNDERSTORM.

	ONSET...After 3 AM.

SIGNIFICANT WINDS.
	RISK...Elevated.
	AREA...Eastern Oklahoma and Western Arkansas.
	ONSET...Ongoing.

DISCUSSION...

Fire weather conditions have improved during the evening as the
dryline retreated. The cold front is now overtaking the dryline from
the northwest. Any ongoing firefighting efforts will be affected by
the wind shift with the front.

Greater coverage of storms are expected into the overnight hours
both ahead of and with the advancing cold front. Storms that develop
ahead of the front, mainly across east-central and southeast
Oklahoma into western Arkansas, would be capable of producing higher-
end severe weather, including very large hail, damaging winds in
excess of 70 mph, and strong tornadoes. Storms that develop along or
behind the front will pose a large hail and wind threat. The severe
threat will wane from northwest to southeast after the cold frontal
passage late tonight into Wednesday morning.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
Activation of the Regional Spotter Network Expected.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday.
WEDNESDAY...High Wind Potential.
THURSDAY...No Hazards.
FRIDAY...Very High Fire Weather Potential.
SATURDAY thru MONDAY...No Hazards.

EXTENDED DISCUSSION...
Low storm chances will persist around daybreak Wednesday morning
over parts of western Arkansas before the cold front exits by mid-
morning. Gusty northwest winds will continue behind the cold
front on Wednesday. With drier air moving into the region, at
least a limited fire weather threat is expected, especially north
of I-44 and west of Highway 75 where ongoing drought conditions
persist.

EMERGENCY MANAGEMENT PLANNING STATEMENT...
Fire fighting personnel may require extra resources across portions
of northeast Oklahoma this afternoon and evening, especially
west of U.S. Highway 75. Emergency managers and first responders
should be prepared for the potential for higher-end severe weather
impacts, including the potential for strong tornadoes. This threat
will be greatest this evening into tonight from southeast
Oklahoma into western Arkansas.
