LIGHT ICING IS OCCURRING THIS MORNING ACROSS PORTIONS OF NORTHEAST
OKLAHOMA AND NORTHWEST ARKANSAS. ICING IS MOST LIKELY ON ELEVATED
SURFACES SUCH AS BRIDGES...TREES AND POWER LINES...AND COULD
POTENTIALLY CREATE HAZARDOUS DRIVING CONDITIONS. AN ISOLATED AND

EXPECTED TO DECREASE IN COVERAGE TOWARD MIDDAY WHILE TEMPERATURES
RISE SLIGHTLY ABOVE FREEZING IN MOST AREAS. MORE ICING IS
EXPECTED TONIGHT INTO SATURDAY MAINLY ALONG AND NORTH OF I-44 AS
TEMPERATURES ONCE AGAIN FALL BACK NEAR FREEZING OR SLIGHTLY BELOW

EXTENDED DISCUSSION...

ANOTHER ROUND OF MORE SIGNIFICANT ICING IS EXPECTED SATURDAY AND
SATURDAY NIGHT NORTH OF I-44 WHEN PRECIPITATION COVERAGE AND
INTENSITY INCREASES AHEAD OF A STRONG UPPER LEVEL STORM SYSTEM.
ICE ACCUMULATION ON POWER LINES AND TREES...AS WELL AS ELEVATED
SURFACES SUCH AS BRIDGES COULD CAUSE POWER OUTAGES AS WELL AS
HAZARDOUS TRAVEL CONDITIONS. FORECAST STORM TOTAL ICE
ACCUMULATIONS IN THE QUARTER TO THREE QUARTERS OF AN INCH RANGE
ARE EXPECTED.

THUNDERSTORM POTENTIAL WILL SUNDAY INTO MONDAY WHEN THE MAIN UPPER
STORM SYSTEM LIFTS NORTHEAST INTO THE PLAINS. AT THIS TIME...IT
DOES NOT APPEAR THAT THE TRUE WARM SECTOR WILL SURGE NORTH INTO
THE REGION...THEREBY LIMITING INSTABILITY AND THE OVERALL SEVERE
THREAT. POCKETS OF LOCALLY HEAVY RAINFALL ARE POSSIBLE...BUT
FLOODING IS NOT EXPECTED TO BECOME A MAJOR THREAT.

EMERGENCY MANAGEMENT PLANNING STATEMENT...

FORECAST ICE ACCUMULATIONS FOR AREAS NORTHWEST OF INTERSTATE 44
WOULD LIKELY RESULT IN SCATTERED POWER OUTAGES THAT COULD EXTEND
INTO MULTIPLE DAYS.  PREPARATIONS FOR SUCH POWER OUTAGES SHOULD
BE MADE ALONG WITH EMPHASIZING PROPER GENERATOR SAFETY PROCEDURES.
