Washtenaw County school district officials haven't started talking about canceling classes Wednesday due to the anticipated snowstorm, but if the forecast holds true, a decision could be made by Tuesday evening.

Tom Moore, transportation director for the Washtenaw Intermediate School District, said it’s still too early to make a decision for later on in the week. However, if the forecast for the storm is accurate, parents could be getting a call on Tuesday saying school is canceled for Wednesday.

“If it holds true to form, we’ll start seeing those flakes and there’s a possibility that a snow day may be called as early as late Tuesday evening,” he said.

Weather forecasters have predicted 10-15 inches of snow will hit the Ann Arbor area Tuesday night and continue into Wednesday.

Ann Arbor Public Schools spokeswoman Liz Margolis said she hadn’t spoken with interim Superintendent Robert Allen as of 10 a.m. today about the possible storm. She said Allen will begin having conversations with other superintendents from the area Tuesday and said she believes there’s a chance school could be called off Tuesday night.

However, there’s a certain amount of risk when making the decision to cancel classes the night before school, Margolis said.

“I don’t know when it’s slated to start yet — we work off weather services locally and see what the realistic expectation is,” she said. “If we end up calling it in the night before and the storm takes a turn, that’s always the concern.”

Margolis said the latest time Ann Arbor parents would receive a call from the district notifying them school is canceled would be at 10 p.m. Tuesday. The earliest time parents would receive a call on Wednesday morning would be 6 a.m., she said.

Ypsilanti Public Schools spokeswoman Emma Jackson said Superintendent Dedrick Martin was at a breakfast with local legislators this morning, and conversations about canceling school hadn’t yet begun.

“It’s probably unlikely that a decision will be made today on something that may happen by Wednesday morning,” she said. “We’re going to give it a little bit more time.”

All Washtenaw County school districts closed on Dec. 13 after the area received an overnight snowfall of between 4 and 5 inches.

Moore said he was advising districts to take their time when making the decision because weather can change quickly.

“It’s still a little early and, with Michigan being Michigan, wait five minutes and the weather can change,” he said. “We have to see if the forecast comes true.”
