OXFORD, Ohio (AP) _ Bad weather today forced the Ku Klux Klan to cancel a march set for Saturday to protest the suspensions of two boys who wore Klan robes to high school for Halloween and shouted racial slurs.

''I talked to the imperial wizard,'' said police Lt. Bob Holzworth. ''He indicated for safety reasons, they decided to call off the march.''

The National Weather Service issued a winter storm warning for the southern half of Ohio, with 4 to 6 inches of snow forecast by Friday night. High temperatures Saturday are to reach only the teens, with wind chills below zero.

Earlier, Klan officials had expected 500 members and sympathizers in Oxford for the march.

The southwestern Ohio town, the home of Miami University, has a population of about 20,000. About 50 of the school's 1,100 students are black.

Ernie Edwards of Morrow, who said he represented a Klan group called the U.S. Knights, obtained a city permit to march to counter a protest by black residents a week after the Halloween incident.
