Freezing drizzle made driving a dangerous venture this morning in the Oklahoma City area and threatened other parts of the state.

Police, Oklahoma Highway Patrol and other law enforcement and emergency personnel were heading from one accident to another as the number of crashes continued to rise.

Officers were responding to several multiple-vehicle accidents, and some involving overturned automobiles.

The bad news from National Weather Service forecasters: there's more on its way, with snow and ice possible.

Scattered light rain or drizzle formed in a swath from southern Oklahoma through the center of the state.

Forecasters said southwestern Oklahoma appears to be the most likely area for ice accumulation, with lesser amounts in west-central, central and south-central sections of the state, according to the weather service.

Highs today will be in the 30s and 40s. The Panhandle tonight will have a chance of snow and freezing rain with lows dipping into the 20s and 30s.

The precipitation is forecast to fall as rain on Saturday, but a surge of cold air will trigger a decline in temperatures Saturday night and Sunday and possibly result in a mixture of rain and snow, forecasters said.

Still, no significant snow accumulation is forecast, as temperatures are expected to moderate on Sunday.

A winter weather advisory will be effective until 6 p.m. today for Blaine, Caddo, Canadian, Cotton, Clevleland, Comanche, Garvin, Grady, Kingfisher, Lincoln, Logan, McClain, Murray, Oklahoma, Payne, Pontotoc, Pottawatomie, Seminole, Stephens and Tillman counties.

A winter weather advisory means that areas for freezing drizzle may cause travel difficulties.

A winter storm watch is effective from late tonight to late Saturday night for Beaver, Cimarron and Texas counties.

A winter storm watch means there is a potential for significant snow, sleet or ice accumulations, causing travel problems.
