Snow Hole

11:30 PM December 24.

The shadow effect of the North Shore ridge will be felt in Grand Rapids, Warba, and points northeastward toward Ely. As the air flows northwestward up the hill in Duluth, the moisture is rapidly wrung out of the air. This leaves less moisture available for places 30 - 80 miles northwest of the North Shore. Additionally, there is an area of sinking motion downstream from the ridge, which further dries the air and prevents precipitation. These effects may substantially reduce total snowfall in Grand Rapids, Ely, Warba, and areas along and just southeast of the Iron Range. It would not surprise me if total snowfall was as little as 3 or 4" in Grand Rapids.

Well see...
