...Dangerously Cold Wind Chill Values Expected Tonight...

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...Southeastern Oklahoma and Northwestern Arkansas.
ONSET...Ongoing.

WIND CHILL.
RISK...Significant.
AREA...Eastern Oklahoma and Northwest Arkansas.
ONSET...After 9 pm.

DISCUSSION...
A band of snow that developed across northeastern Oklahoma and
northwestern Arkansas this morning continues to dissipate this
evening. Little to no additional accumulation is expected from this
activity.

Another area of precipitation is developing across northern Texas and
this precipitation will spread across portions of southeastern
Oklahoma this evening and early tonight. As arctic air spreads toward
the Red River this evening, any precipitation that forms across
southeastern Oklahoma will likely fairly quickly turn to snow. Any
accumulation from this activity will be light.

Temperatures falling into the single digits and lower teens overnight
combined with north wind of 10 to 20 mph will result in dangerously
cold wind chill values from minus 5 degrees to minus 15 degrees.
Frostbite of exposed skin is possible in these conditions in less
than 30 minutes.

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

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday.
TUESDAY...High Wind Potential...Dangerous Wind Chill Potential.
WEDNESDAY...Dangerous Wind Chill Potential.
THURSDAY...No Hazards.
FRIDAY...High Wind Potential.
SATURDAY...Thunderstorm Potential...High Wind Potential.
SUNDAY...Thunderstorm Potential.

EXTENDED DISCUSSION...
Dangerously cold wind chill will persist into Tuesday afternoon
across much of the region as temperatures recover only into the teens
to around 20 degrees with a northerly wind continuing. The arctic
system settles over the region Wednesday morning resulting in very
cold temperatures but the wind will weaken. The coldest temperatures
will be over snow-covered ground in far northeastern Oklahoma and far
northwestern Arkansas.

A strong storm system is expected to develop into the Southern
Rockies late this week. Southerly low level flow will return to our
region ahead of this system, allowing for a warming trend to begin
Thursday and continue through the weekend. The main system will move
through the Southern Plains late this weekend, resulting in showers
and isolated thunderstorms across the area Saturday night and Sunday.
