With the current forecast highs, the coldest high-temperature records are in jeopardy Monday and Tuesday. Grand Rapids and Muskegon are on track to set new record cold days. 

This arctic outbreak is unusual this early in the season. High temperatures will be over 20 degrees cooler than average. 

Accumulating snow is also likely for the beginning of the week. Snow begins Sunday night and could bring several inches of snow by mid-day Monday. Lake-effect snow will develop Monday night and continue Tuesday. 

Weather models are still disagreeing on snow totals, but tend to agree on the lakeshore getting the highest totals, especially near and south of South Haven.
