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 >

Overview

A strong low pressure system brought a spring snowstorm to the region on Friday, April 13, 2018. Precipitation began as rain, and even a few thunderstorms were reported. Then as cold air filtered into the area, rain changed to snow. Heavy snow was reported across much of western and south central SD, and strong northerly winds resulted in blizzard conditions from blowing snow.
