Cold air advection has returned this afternoon ahead of the next blast of arctic air. Late afternoon 850mb temperatures ranged from -20 to -24C with surface temperatures in the single digits in northern Minnesota to the low/mid teens farther south across east central Minnesota and northwest Wisconsin.
Tonight: High pressure builds southeast out of the northern Rockies, reaching southwest Minnesota by daybreak. Some clouds tonight with a few flurries possible, but the main weather story will once again be the temperatures as they fall into the teens, 20s and 30s below zero.
Tuesday: High pressure exits to the southeast while a weak system approaches from the west, this feature could lead to a little bit of snow in parts of the area for Tuesday night but snowfall accumulations should remain under an inch. Highs Tuesday will range from around zero to the single digits above zero with lows Tuesday night ranging from around 10 below to the single digits above zero.
Note: No end to this cold weather pattern with reinforcing shots of cold air likely for mid to late week and probably through the weekend.
