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

.DAY ONE...This Evening and Tonight.

WINTER WEATHER.
SNOW ACCUMULATION.
RISK...Limited.
AREA...Northeastern Oklahoma and Northwestern Arkansas.
ONSET...After Midnight.

DISCUSSION...
Another surge of arctic air will spread from the Central Plains into
the Southern Plains late tonight. Lift over this arctic air will
result in areas of snow to form across northeastern Oklahoma and
northwestern Arkansas. Light accumulations of less than half an inch
are possible over these areas by sunrise Monday.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
Spotter Activation Not Expected.

.DAYS TWO THROUGH SEVEN...Monday through Saturday.
MONDAY...Winter Weather Potential...Dangerous Wind Chill Potential.
TUESDAY and WEDNESDAY...Dangerous Wind Chill Potential.
THURSDAY...No Hazards.
FRIDAY and SATURDAY...High Wind Potential.

EXTENDED DISCUSSION...
The area of snow will likely expand across more of northeastern
Oklahoma and northwestern Arkansas Monday morning. Total snow
accumulations of up to one to one and a half inches are possible
before the snow tapers off by late Monday afternoon. Although the
precipitation will end across northeastern Oklahoma and northwestern
Arkansas during Monday afternoon, a light wintry mix of precipitation
is expected to organize across far southeast Oklahoma into west
central Arkansas late Monday afternoon into Monday night. Light
accumulations of snow are possible there, and light icing is also
possible near the Red River Monday night.

Strong north winds behind the cold front will produce dangerously
cold wind chill values Monday night into Tuesday across northeast
Oklahoma and northwest Arkansas. Wind chills between zero and 15
below are expected. Wind chills across southeast Oklahoma and west
central Arkansas will range from zero to 5 above. While it will be
even colder temperature wise Tuesday night into Wednesday morning,
winds will be lighter during this time as the arctic high pressure
settles over the region. Wind chill values will be from zero to 5
degrees above zero.

A strong upper level storm system will take shape over the
southwestern U.S. late this week, allowing strong southerly wind to
develop across the Southern Plains ahead of it. Warmer weather along
with a chance of showers and thunderstorms is expected as this system
shifts east toward our area late next weekend.
