34. Arctic blast in the Midwest
After being buried under more than a foot of snow, parts of
the Rockies and Upper Midwest were getting their first icy
touch of arctic air on Tuesday. And the rest of the Midwest
and the East are expecting a dose later in the week, with
temperatures forecast as much as 40 degrees below average.
The frigid air was pushed in by a powerful storm that hit
Alaska with hurricane-force winds over the weekend. (AP-PHOTOS)
