Minnesota has a case of the chronic cold.
Dangerous subzero temperatures and whipping winds just won't let up, with another string of far-below-zero readings expected Sunday night through Tuesday, rivaling the deep freeze earlier this month.
The persistent cold puts this month on pace to be in the top five coldest Januarys in about the past three decades, sparking a rare number of school closings due to the cold.
Already, Winona and Rochester public schools have called off classes Monday because of windchills expected from minus-40 to minus-55. Other districts, such as Minneapolis, St. Paul, Edina and Robbinsdale, plan to decide by Sunday night.
If they cancel, it will be the fourth time since Jan. 6.
"I've never seen anything like this," said Ruth Dunn, the spokeswoman for the Burnsville-Eagan-Savage School District. "Two [canceled days] would be rare. But four? It's really a disruption to families' schedules, but I think parents understand it's for students' safety."
In a rare step, Gov. Mark Dayton shut down schools statewide Jan. 6 — the first time a governor had ordered schools to close since 1997. State leaders said it was for the safety of students during a 62-hour spell of subzero temps. Then, several schools canceled class the next day and again last Thursday.
Monday's forecast is a bit of déjà vu.
