An outbreak of arctic air will bring the lowest temperatures of the season so far and dangerous cold to the Midwest this weekend, before moving into the East early this week. The latest arctic blast will send thermometer readings to the minus 20s F over part of the northern Plains and the Upper Midwest. The temperature may stay below zero for 48 hours in parts of North Dakota and Minnesota this weekend. AccuWeather RealFeelĀ® temperatures will be life-threatening if people venture out without being properly dressed from the northern Plains to the Ohio Valley.

According to AccuWeather Chief Long-Range Meteorologist Paul Pastelok, “The arctic deep freeze will last two to three days in most places.” Highs from New York City to Washington, D.C., will be below freezing during the first part of the week. Overnight lows will mainly be in the teens. Temperatures will average 10-20 degrees below average in the North Central states and 5-10 degrees below average in the East. Typical highs during the middle of January range from the lower 20s around Minneapolis to the upper 30s in New York City. FULL REPORT
