Very Cold Upper Midwest

Not much change locally. But as large storm heads toward the Northeast, very frigid arctic air has intruded into north-central U.S.

View above is from Duluth, Minnesota, this morning. Below is 1323 UTC surface plot for North Central U.S. Note the very cold temperatures west and north of Lake Superior. Temperatures down to below -30 F in northern Minnesota, and in southern Canada some stations were reporting colder than -40 F. Coldest outbreak that I can remember in quite some time.
