...MAJOR WINTER STORM TAKING SHAPE ACROSS EASTERN OKLAHOMA AND
NORTHWEST ARKANSAS...

THIS OUTLOOK IS FOR NORTHWEST AND WEST CENTRAL ARKANSAS AS WELL AS
MUCH OF EASTERN OKLAHOMA.

.DAY ONE...TODAY AND TONIGHT.

WINTER WEATHER.
SNOW ACCUMULATION.
RISK...ELEVATED.
AREA...NORTHEAST AND EAST CENTRAL OKLAHOMA...NORTHWEST ARKANSAS.
ONSET...MID TO LATE MORNING.

ADDITIONAL ACCUMULATIONS IN LATER PERIODS.

ICE ACCUMULATION.
RISK...SIGNIFICANT.
AREA...SOUTHEAST OKLAHOMA AND WEST CENTRAL ARKANSAS.
ONSET...THIS MORNING.

SIGNIFICANT WINDS.
RISK...LIMITED.
AREA...EASTERN OKLAHOMA AND NORTHWEST ARKANSAS.
ONSET...ONGOING.

DISCUSSION...
A COLD AIRMASS HAS OVERSPREAD THE REGION TONIGHT...WITH THE FREEZING
LINE CURRENTLY RUNNING FROM JUST NORTH OF FORT SMITH INTO PUSHMATAHA
COUNTY. THE FIRST WAVE OF PRECIPITATION IS CURRENTLY UNDERWAY
ACROSS SOUTH CENTRAL OKLAHOMA...AND THIS ACTIVITY WILL EXPAND IN
COVERAGE THROUGH THE MORNING HOURS AS IT LIFTS NORTHEAST ACROSS MUCH
OF THE AREA. PRECIPITATION MAY BEGIN AS RAIN IN FAR SOUTHEAST
OKLAHOMA AND WEST CENTRAL ARKANSAS...BUT EXPECT A TRANSITION TO
FREEZING RAIN AND SOME SLEET AS THE COLDER AIR DEEPENS. AREAS
FARTHER NORTH UP TO THE INTERSTATE 44 CORRIDOR WILL LIKELY SEE A
MIXTURE OF SLEET AND SOME SNOW. TEMPERATURES WILL NOT WARM
TODAY...SO ANY PRECIPITATION WILL RESULT IN HAZARDOUS ROADS AND
HIGHWAYS.

ANOTHER ROUND OF WINTRY PRECIPITATION WILL SPREAD INTO THE AREA
LATER THURSDAY NIGHT INTO FRIDAY...BRINGING THE BEST CHANCES OF
SIGNIFICANT ACCUMULATIONS. SIGNIFICANT ICE ACCUMULATIONS ARE
EXPECTED ACROSS SOUTHEAST OKLAHOMA AND WEST CENTRAL ARKANSAS...WHERE
AROUND A HALF INCH TO AN INCH OF ICING WILL BE POSSIBLE. THIS WILL
RESULT IN MAJOR TRAVEL IMPACTS AND POWER OUTAGES. THE AREAS ROUGHLY
BETWEEN THE INTERSTATE 40 AND 44 CORRIDORS MAY SEE AROUND 3 TO 6
INCHES OF SLEET AND SNOW ACCUMULATIONS...WITH SOME LOCALLY HIGHER
AMOUNTS POSSIBLE. IF SLEET REMAINS THE DOMINANT PRECIPITATION TYPE
THROUGH THE NIGHT...THEN THE SNOWFALL TOTALS WILL BE LESS.
REGARDLESS...WIDESPREAD TRAVEL ISSUES ARE LIKELY.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
SPOTTER REPORTS OF PRECIPITATION TYPE...ACCUMULATIONS AND TRAVEL
CONDITIONS WOULD BE APPRECIATED.

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY.
FRIDAY AND SATURDAY...WINTER WEATHER POTENTIAL...DANGEROUS WIND
CHILL POTENTIAL.
SUNDAY...WINTER WEATHER POTENTIAL.
MONDAY AND TUESDAY...DANGEROUS WIND CHILL POTENTIAL.
WEDNESDAY...NO HAZARDS.

EXTENDED DISCUSSION...
A MIX OF MOSTLY SNOW AND SLEET WILL PERSIST INTO EARLY FRIDAY...WITH
ADDITIONAL ACCUMULATIONS LIKELY ACROSS NORTHEAST OKLAHOMA AND
NORTHWEST ARKANSAS. A MIX OF FREEZING RAIN AND SLEET WILL BE ONGOING
EARLY FRIDAY AS WELL ACROSS SOUTHEAST OKLAHOMA AND WEST CENTRAL
ARKANSAS. THE WINTRY PRECIPITATION IS EXPECTED TO PUSH EAST OF THE
REGION DURING THE AFTERNOON.

SATURDAY WILL GET OFF TO A VERY COLD START...WITH MORNING WIND CHILL
VALUES BELOW ZERO FOR MOST OF THE AREA. ANOTHER ROUND OF LIGHT
SNOW... SLEET OR FREEZING DRIZZLE IS EXPECTED TO DEVELOP LATE
SATURDAY AND CONTINUE INTO SUNDAY. ADDITIONAL LIGHT ACCUMULATIONS
WILL BE POSSIBLE WITH THIS PRECIPITATION.

YET ANOTHER SHOT OF ARCTIC AIR WILL PUSH THROUGH THE REGION SUNDAY
NIGHT INTO MONDAY. DEPENDING ON HOW MUCH SLEET AND SNOW COVER
EXISTS...TUESDAY MORNING LOWS COULD FALL INTO THE SINGLE
DIGITS...POSSIBLY NEAR ZERO IN A FEW LOCATIONS.

EMERGENCY MANAGEMENT PLANNING STATEMENT...
EMERGENCY MANAGERS NEED TO BE PREPARED FOR PROLONGED TRAVEL ISSUES
AND POTENTIAL POWER OUTAGES ACROSS THE REGION. SHELTERS MAY BE
NEEDED DUE TO THE VERY COLD WEATHER EXPECTED OVER AN EXTEND PERIOD.
