Monday and Tuesday we will experience the coldest days since February 10, 2011 with highs in the single digits and low teens with lows near or below zero.
Wind chills could dip to -20. There will be scattered flurries across Chicago and Lake Effect Snow along the shoreline in lower Michigan.
By Wednesday we warm to near 20 and Thursday we will be in the mid-20s ahead of a southern plains storm system. Light snow is possible late Thursday and Friday.
This pattern of cold Arctic air spilling into the region with limited warm days will be with us for much of February. In other words Winter has arrived late, but it's here to stay.
