An Arctic airmass will continue impacting the U.S. this weekend before another round of bitter temperatures occurs at the beginning of the work week.
A Canadian high pressure system centered over the Mid-Atlantic today. This system will allow for cold Arctic air to seep into the U.S. through the weekend.
Unseasonably cold weather continued from the High Plains into the Great Plains Friday. Morning lows struggled to get out of the teens and 20s for most locations, including Grand Forks, N.D., Minneapolis, Milwaukee, Wis., Chicago, and Grand Rapids, Mich. A temperature near Cook, Minn. fell to a bitter 10 degrees earlier this morning. Saturday's lows will not be as extreme, but parts of the northern Plains will still see temperatures dipping to the teens and 20s.
Further east Saturday morning, much of the Eastern Seaboard will see morning lows 5 to 10 degrees below normal thanks to that high pressure system. The Northeast and Mid-Atlantic will see morning low temperatures in the mid-20s and low-30s while the Southeast, with the exception of Florida, will see morning lows in the low-to-mid 40s.
Another system will swing down from British Columbia, Canada on Sunday and drop temperatures very low once again. The Dakotas and Minnesota could see lows drop to single digits and even below zero in spots by Monday morning.
In addition to the cold air, winds will be breezy across the northern tier when temperatures are at their lowest. The highest winds are set to occur across the north-central U.S. This means that wind chills will be in play and will likely be near or below zero for many areas Monday morning.
Remember when going outside in very cold wind chills, covering exposed skin should be your main concern. However, even with your skin covered, wind chills can still be dangerous when exposed to the cold for long periods of time. The best course of action is to stay inside when these conditions exist. If you need to go outside, remember to dress in layers and minimize skin exposure.
