Eastern and Western Storms

A strong cold front will sweep across the eastern U.S. with gusty winds, showers and thunderstorms, and lake effect snow. A slow moving western system will bring locally heavy rain that could cause flash flooding and heavy mountain snow. Heavy snow and blowing snow is expected across much of the northern 2/3rds of Alaska from two strong weather systems. Read More >

Overview

This strong fall storm system produced storm-force gusts (defined as greater than 47 kt, or 54 mph) on Lake Superior as well as lakeshore flooding along the Bay of Green Bay shoreline. The water level on the Lakes Michigan-Huron system was already at nearly a record high from about a year of anomalously high precipitation. Combined with the prolonged east wind with this storm pushing water to the west, lakeshore flooding affected nearly all of the Bay of Green Bay.
