O’FALLON, Mo. (KMOX) – The decision to cancel classes is a tough one to make according to Fort Zumwalt School Superintendent Dr. Bernard Dubray who says while the precipitation totals and timing are never certain, one thing is.

“It’s just a tough call. At this point we’re talking about snow north of I-70 and ice south of I-70. Highway 70 splits our school district,” Dr. Dubray said.

Fort Zumwalt School District is closed today.

But Dr. Dubray said he actually had three decisions to make: Close school for the entire day, just cancel after school activities, or dismiss children early. But one thing he does know is that parents expect him to make the right decision and hold classes if they can.

In Edwardsville, Superintendent Ed Hightower says he doesn’t like to cancel classes in the middle of the day and begins his decision making at 3 a.m. when buses are sent out on a test run of the worst roads in the district.

Hightower along with dozens of schools also canceled classes today for children in their districts.
