Official National Weather Service forecasts for the Upper Peninsula — all fifteen counties, from the Mackinac Bridge and Sault Ste. Marie west along US-2 to Escanaba and Iron Mountain, and up the Keweenaw through Houghton to Copper Harbor.
Every Michigan region shares one system — the same maps, the same live radar, the same climate record. The Keweenaw is the snowiest place east of the Rockies that anyone lives in — 200 inches is an ordinary winter and the record season passed 390. Lake Superior never warms enough to stop feeding it, the same lake holds summer in the fifties on the shore, and the November gales that sank the Fitzgerald come through here every year.
