ICING POTENTIAL ALONG THE INTERSTATE 44 CORRIDOR AND ACROSS
EXTREME NORTHWEST ARKANSAS.  ANY ICE ACCUMULATIONS THROUGH
EARLY FRIDAY MORNING ARE LIKELY TO BE ONE TENTH OF AN INCH
OR LESS.  HOWEVER THIS IS ENOUGH ICE TO CAUSE SLICK SPOTS

SIGNIFICANT ICE ACCUMULATIONS OF ONE HALF TO THREE QUARTER
INCHES ARE FORECAST FOR AREAS NORTHWEST OF A LINE FROM
NOWATA OKLAHOMA TO STILLWATER OKLAHOMA.  THESE AMOUNTS WILL LIKELY
CAUSE IMPACTS TO THE ELECTRICAL INFRASTRUCTURE RESULTING IN
POWER OUTAGES.  FURTHER SOUTH...ICING AMOUNTS OF ONE
TENTH TO ONE QUARTER INCH ARE MORE LIKELY ALONG THE INTERSTATE
44 CORRIDOR OF NORTHEAST OKLAHOMA.  ANY POWER OUTAGES WITHIN THIS
ZONE ARE MORE LIKELY TO BE ISOLATED AND OF SHORTER DURATION.
TEMPERATURES WILL RISE ABOVE FREEZING FOR ALL OF NORTHEAST OKLAHOMA
DURING THE DAY ON SUNDAY ENDING THE RISK FOR ADDITIONAL ICING.

WIDESPREAD SHOWERS AND ISOLATED THUNDERSTORMS WILL THEN SWEEP
THROUGH THE REGION LATE SUNDAY THROUGH MONDAY...WITH LOCALLY HEAVY
