...ADDITIONAL ICING EXPECTED THIS AFTERNOON AND TONIGHT...

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

.DAY ONE...This Afternoon and Tonight.

WINTER WEATHER.
SLEET ACCUMULATION.
RISK...Very Limited.
AREA...Northeast Oklahoma.
ONSET...This afternoon.

ICE ACCUMULATION.
RISK...Limited.
AREA...Along and northwest of a McAlester to Muskogee to Rogers to
            Berryville line.
ONSET...This Afternoon.

DISCUSSION...

The next wave of precipitation, currently over northern Texas and
southwest Oklahoma, will spread across eastern Oklahoma and
eventually into western Arkansas this afternoon and evening.
Temperatures to the northwest of a line from near McAlester to
Muskogee to Rogers to Berryville will remain near or below
freezing as the precip moves across, thus freezing rain and/or
sleet are the expected precip types. Freezing rain and sleet will
become more focused across northeast Oklahoma and far northwest
Arkansas this evening with the heaviest icing generally along and
west of U.S. Highway 75, where between a tenth to two tenths of
additional icing is possible by tonight. Precipitation should begin
to taper off after midnight, with some freezing drizzle likely
lingering after the main precip event is over.

The freezing precipitation is expected to create slick spots on
roadways, especially bridges and overpasses, making travel
potentially hazardous later today into tonight. Some sporadic power
outages are possible as well.

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

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday.
THURSDAY through FRIDAY...Thunderstorm Potential...Heavy Rain Potential.
SATURDAY...Thunderstorm Potential.
SUNDAY through TUESDAY...No Hazards.

EXTENDED DISCUSSION...
Additional rounds of widespread shower and thunderstorm activity
are expected throughout the week. This will result in more
potential flooding and flash flooding through the end of the week,
with highest amounts expected across southeast Oklahoma into
northwest Arkansas.
