Lake-effect Snow and Whiteout Conditions in the Great Lakes Region; Below-average Temperatures in the East

Heavy lake-effect and lake-enhanced snow will persist downwind of the Great Lakes and produce some whiteout conditions that could cause difficult travel conditions. A coastal low will produce moderate to heavy snow over parts of southern and eastern New England into the afternoon. Below average temperatures are expected across the eastern U.S., particularly with chilly morning temperatures. Read More >

Two rounds of snow are expected Tuesday and Wednesday. The first round on Tuesday will likely drop 1 to 3" mainly over western through central ND, with the highest amounts favored in the southwest. For Wednesday, another 1 to 2" of snow, along with windy conditions, are possible. Combined totals for any one location should generally remain at 3" or less, though locally higher amounts are possible.
An extremely cold air mass (by far the coldest this winter) will bring dangerous to life-threatening wind chills to much of the state Thursday through Saturday. Low temperatures over this time period are forecast in the 20s and 30s below zero. Friday will be the coldest day when high temperatures could be limited to the teens below zero for most areas.
There are medium to high chances for maximum temperatures in the teens below zero on Friday.
