Crash after crash clogged metro area freeways in the Twin Cities long after the evening rush hour should have ended Monday night. It was all courtesy of a snowfall that caused slick roads, poor visibility and temperatures more reminiscent of late February than the second day of April. The snow was expected to continue through Tuesday evening, with totals reaching anywhere from 6 to 10 inches across southern Minnesota. The Minnesota Department of Transportation reported more than 25 crashes on state and interstate highways — just in the metro area between 8 p.m. and 8:15 p.m. Monday.
