Discussion              

Colder air will push into the region today following the passage of a slow-moving frontal system that will then stall out just to the south of here. A wave of low pressure will push along the stalled-out frontal boundary zone later tonight and it could produce a wintry mix in the evening and then some snow late tonight and early Wednesday. After a moderately cold day on Thursday, a strong Arctic front will blast through here on Friday morning and it’ll usher in two-day shot of some very cold air with painful wind chills and lows in the low-to-mid teens by early Saturday.
