It will be an active January weekend, just not in the typical sense. A pair of upper-level systems merged across the Plains today. Parts of the Midwest and Plains experienced periods of heavy snow and significant icing today. The eastern Dakotas, Iowa, and Minnesota experienced blizzard conditions. The system will move through the Ohio Valley, Great Lakes, and Mid-Atlantic into the weekend. The whole array of wintry precipitation is on the table. But for the Bluegrass, it will be just rain Saturday.
All of the wintry weather will remain to our north. But don't worry, we'll get in on winter. The cold front associated with this strong system will open the freezer door. The core of the coldest air will remain near the Canadian border. Much colder air will seep southward through the Southeast.
Like it or not much, much colder will arrive by Sunday. Temperatures will struggle to climb out of the 20s. It will be a blustery day too with wind chills in the teens throughout the day. This Arctic air mass will linger into the start of the week. Lows will be in the teens with highs struggling to reach freezing through Tuesday. These will be some of the coldest temperatures that we have experienced this winter.
