.SHORT TERM...
(Tonight)
Issued at 158 PM CST Sun Dec 5 2021

Cold front currently across northern KS will move into northeast
OK shortly after 00Z, and short-term guidance remains consistent
with initial storm development along the boundary around 02-03Z.
This activity will continue to organize along the advancing cold
front through the evening, with storms likely exiting the forecast
toward 09Z. Lingering SBCAPE around 750-1000 J/KG and 35-45kts of
deep-layered shear should be sufficient for a few severe storms,
especially across parts of western AR and far southeast OK.
Damaging straight-line winds/large hail remains the biggest
threat, along with a very low tornado threat with any bowing
segments.

&&

.LONG TERM...
(Monday through Sunday)
Issued at 158 PM CST Sun Dec 5 2021

Expect a breezy and much chillier airmass to overspread the area
on Monday. Have continued to use the NBM 90th percentile for
winds/gusts tonight into Monday, and wouldn't be surprised to see
a few gusts push advisory criteria. Monday and Tuesday will
feature below normal temps, with highs mostly remaining in the
40s.

Milder weather returns by Wednesday as mid-level heights rise and
southerly winds pick up. Well above normal temperatures appear
likely for Thursday and especially Friday as south/southwest
winds become gusty ahead of the next cold front. Highs will likely
bounce back well into the 70s for Friday.

A vigorous longwave wave is proggd to move into the Plains over
the weekend, with an associated cold front likely sweeping through
the area by Saturday. Light wintry weather continues to be a
possibility, although the longer range guidance continues to
struggle for any consensus concerning location of colder
air/precipitation. Will maintain the mention of a light wintry
mix mainly for Saturday night into early Sunday, although this
remains a low confidence forecast. We'll continue to monitor this
closely over the next several days.

.AVIATION...
(00Z TAFS)
Issued at 518 PM CST Sun Dec 5 2021

Cold front has entered far NE OK and will make steady progress
southward overnight and likely pushing south of KMLC/KFSM around
midnight. MVFR to low VFR ceilings will likely remain in place
from SE OK through western AR ahead of the frontal passage.
Showers and storms are expected to develop this evening along the
frontal boundary and quickly expand in coverage along the
frontal corridor. Additional prefrontal convection may develop
across portions of western AR, otherwise aviation impacts due to
storms will end within a few hours of the frontal passage. Gusty
northerly winds will continue into the day Monday before gradually
decreasing mid to late afternoon.

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

.DAY ONE...Today and Tonight.

SEVERE THUNDERSTORM.
	RISK...Limited.
	AREA...Southeast of I-44.
	ONSET...After 8 PM.

HEAVY RAIN.
	RISK...Limited.
	AREA...Southeast of I-44.
	ONSET...After 8 PM.

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

FIRE WEATHER DANGER.
	RISK...Limited.
	AREA...Northeast Oklahoma.
	ONSET...Ongoing.

DISCUSSION...
There is a limited risk of severe thunderstorms this evening,
continuing into the overnight hours, across eastern Oklahoma and
western Arkansas to the south of Interstate 44. Thunderstorms are
expected to develop early this evening as a strong cold front moves
into the area. Damaging straight line winds will be the main threat,
with a lower potential for large hail, and much lower threat of
tornadoes.

Prior to the arrival of the front this evening, isolated to
widely scattered thunderstorms may develop across southeastern
Oklahoma and northwestern Arkansas. Severe weather is not expected
with this activity.

South to southwesterly wind will gust to near 30 mph into this
evening. The strong wind gusts along with humidity around 30
percent, will support a limited fire spread threat into early this
evening generally west of U.S. Highway 75 in northeast Oklahoma.
Once the front passes tonight, winds will then shift to the north
and gust to 35 mph.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
Local Spotter Activation May Be Needed.

.DAYS TWO THROUGH SEVEN...Monday through Saturday.
MONDAY...High Wind Potential.
TUESDAY through THURSDAY...No Hazards.
FRIDAY...Thunderstorm Potential.
SATURDAY...No Hazards.

EXTENDED DISCUSSION...
Gusty northerly winds will continue into the daylight hours on Monday,
with a decreasing trend expected toward the evening as surface high
pressure moves into the area.

A low chance of rain will exist Tuesday night across western Arkansas
and adjacent portions of far eastern Oklahoma. Temperatures may be
cold enough in higher elevation areas to support a wintry mix, but
the overall probability of wintry impacts is low at this time.

South to southwest winds will increase Friday ahead of the another
strong cold front set to move through during the weekend.
