WINTER WEATHER.
ICE ACCUMULATION.
RISK...ELEVATED.
AREA...NORTH OF A LINE FROM OKEMAH TO TULSA TO MIAMI.
ONSET...ONGOING.

DISCUSSION...
PERIODS OF FREEZING RAIN HAVE LED TO LIGHT ICING ACROSS PORTIONS
OF NORTHEAST OKLAHOMA THIS MORNING...MAINLY ON ELEVATED SURFACES
SUCH AS BRIDGES...TREES AND POWER LINES. PRECIPITATION IS EXPECTED
TO INCREASE IN COVERAGE AGAIN LATER THIS AFTERNOON THROUGH
TONIGHT...WHILE SURFACE TEMPERATURES SHOULD REMAIN AT OR BELOW
FREEZING NORTH OF AN OKEMAH TO TULSA TO MIAMI LINE. ADDITIONAL
ICING IS EXPECTED OVERNIGHT WITH SOME POWER OUTAGES POSSIBLE AS
ICE ACCUMULATIONS UP TO A HALF INCH ARE POSSIBLE THROUGH SATURDAY
MORNING. TRAVEL WILL ALSO BE HAZARDOUS IN AREAS NEAR THE KANSAS
BORDER WHERE TEMPERATURES WILL REMAIN IN THE UPPER 20S.

.DAYS TWO THROUGH SEVEN...SATURDAY THROUGH THURSDAY.
SATURDAY...WINTER WEATHER POTENTIAL.

EXTENDED DISCUSSION...
THE THREAT OF SIGNIFICANT ICING IS EXPECTED TO CONTINUE SATURDAY
AND SATURDAY NIGHT ACROSS PARTS OF NORTHEAST OKLAHOMA. FURTHER
ICE ACCUMULATION ON POWER LINES AND TREES COULD CAUSE POWER
OUTAGES...WITH HAZARDOUS TRAVEL CONDITIONS IN SOME AREAS. FORECAST
STORM TOTAL ICE ACCUMULATIONS IN THE QUARTER TO THREE QUARTERS OF
AN INCH RANGE ARE EXPECTED. AREAS TO THE SOUTH OF A PAWNEE TO
VINITA LINE SHOULD SEE TEMPERATURES RISE ABOVE FREEZING DURING THE
MORNING SATURDAY...ENDING THE THREAT OF ADDITIONAL ICING.

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.
