Snow fell across a wide section of Oklahoma Wednesday night and early Thursday, causing hazardous conditions on roadways and a number of traffic accidents. One person was killed in a crash on an icy highway in the northeastern part of the state.

The National Weather Service said the storm system produced up to 3 inches of snow at locations in central, northern and southern Oklahoma. A freeze warning was in effect for much of the region, with temperatures expected to dip into the 20s by Thursday night.

The wintry blast is unusual for this time of year in Oklahoma.

Weather service meteorologist Cheryl Sharpe said the forecast low in Oklahoma City Thursday evening was 24 degrees, just one degree warmer than a record low set in 1965.

"The clouds will break up today and it will be clear tonight," she said. "That will allow the air to cool more than if it were cloudy."

Several multi-vehicle accidents were reported on the Interstate 40 crosstown freeway in Oklahoma City between Interstate 44 and Interstate 35. Accidents were also reported on the heavily traveled Broadway Extension. Morning traffic was backed up in several areas, and cars could be seen skidded off to the side of some roads. No serious injuries were immediately reported.

Eastbound Interstate 244 in Tulsa was closed for about two hours because of a traffic accident.

A woman was killed about 3:45 a.m. in a crash on Oklahoma 51 near Mannford.

Sharon Wright, 59, died after losing control of her car, which then rolled down an embankment and landed on its top, according to the Oklahoma Highway Patrol.

The cause of the crash was still under investigation, but it was snowing at the time and the road was icy, the OHP said.

Relatively warm ground temperatures prevented the snow from sticking on many roadways, but some raised bridges and overpasses were icy.

Will Rogers World Airport in Oklahoma City and Tulsa International reported no delays in arrivals or departures.

A gradual warming trend was expected in the state later this week and next, with high temperatures in the 50s Friday and reaching the 60s on Sunday. There was also a chance of precipitation in the forecast for next week.
