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

.DAY ONE...Today and Tonight.

POOR VISIBILITY.
RISK...Limited.
AREA...Eastern Oklahoma and northwest Arkansas.
ONSET...Ongoing.

DISCUSSION...
Patchy fog and light drizzle will continue across eastern Oklahoma
and northwest Arkansas through mid morning before lifting.

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

.DAYS TWO THROUGH SEVEN...Friday through Wednesday.
FRIDAY...Thunderstorm...Winter Weather...High Wind Potential.
SATURDAY...Winter Weather and High Wind Potential.
SUNDAY...No Hazards.
MONDAY...High Wind Potential.
TUESDAY...Winter Weather Potential.
WEDNESDAY...No Hazards.

EXTENDED DISCUSSION...
An arctic cold front will push through the region late Friday night
into Saturday morning, ushering in a very cold air mass. Isolated
thunderstorms will be possible ahead of the front Friday night, a few
of which could be marginally severe across far southeast Oklahoma
with a threat for large hail. In addition, locally heavy rainfall
will also be possible.

The precipitation will transition Saturday morning from rain to a
wintry mix to quickly snow as colder air filters into the area
behind the arctic front. Travel impacts will be possible with the
potential for accumulating snow greatest along and north of I-40.
A north wind will gust at 30 to 35 mph behind the front.

In addition to the potential travel impact from accumulating snow,
dangerous wind chills are likely Saturday night into Sunday morning.
Wind chills in the single digits are expected as temperatures drop
into the teens across much of the area with north winds around 10 mph.

Gusty south winds will develop on Monday as quick moving upper trough
approaches. This system will bring a limited threat for wintry weather
across northeast Oklahoma and northwest Arkansas on Tuesday.

EMERGENCY MANAGEMENT PLANNING STATEMENT...
The exact track and strength of Saturday`s storm system will
determine where the heaviest snow falls and how much accumulation
there will be. Forecasts will continue to be refined in the coming
days, so continue to monitor this situation. Some areas of
northeastern Oklahoma and northwestern Arkansas could experience
significant winter weather impacts given the snow potential, cold
temperatures, and strong wind.
