An Arctic cold front is crashing east, bringing falling temperatures and below-zero lows to parts of the Northern Tier and Upper Midwest. The Arctic front brought snow to Minneapolis Monday morning as the temperature dropped 10 degrees in just two hours, from 30 to 20. The high temperature is only forecast at 4 degrees, while lows tomorrow night may plummet to near minus-10.
