Arctic 48 hours, thaw begins Friday

Cold enough for ya?

Many Minnesotans have had enough of winter's cold at this point in the season. Close your eyes and take a long nap, until Friday afternoon. You'll wake up in a much milder weather pattern.

In the meantime, brace yourself for arctic air for 48 more hours.

A gush of milder air changed snow to rain last night in Boston just as the city was closing in on the all time single season snowfall record.

Meanwhile winter storm warnings are flying for a big swath of states in the central and eastern United States.
