      Lake Effect Snow Warnings Issued for Keweenaw Peninsula

      The latest clipper will sweep southeastward into the northern Great Lakes today (Wednesday). Behind the system, lake effect snow, strong winds and blowing snow are expected for much of west/central Upper Michigan.

      The worst conditions are expected over the western counties through the Keweenaw Peninsula Wednesday afternoon into early evening. A lake effect snow warning has been issued for northern Houghton and Keweenaw Counties effective from noon Wednesday through early Thursday morning.

      Lake effect snow advisories will remain in effect for Gogebic, Ontonagon, southern Houghton, Baraga, Marquette and Alger Counties from noon Wednesday through early Thursday.

      Peak wind gusts of 35-45 MPH are expected, especially over the exposed portions along the Lake Superior shoreline and through the Keweenaw Peninsula. Blowing/drifting snow, reduced visibility and frequent white out conditions are expected initially in our western counties Wednesday afternoon. However, significantly reduced visibility along with blowing and drifting snow will spread as far eastward as Alger County through late Wednesday afternoon and evening.

      The heaviest snowfall is expected over the Keweenaw Peninsula, where 4-8â?? of new snow is possible. Elsewhere, much of north/central Upper Michigan can expect 3-6â?? of new snow.

      Again, new snow accumulation combined with gusty winds and blowing snow will lead to frequent white out conditions, making for difficult travel weather for our western counties by mid afternoon. Hazardous driving conditions will spread eastward through Baraga, Marquette, and Alger Counties by late Wednesday afternoon/evening, lasting through Wednesday night.

      Warnings and advisories are set to expire at 5 a.m. EST Thursday for the entire viewing area. Drier air and westerly winds mean gradually improving weather conditions early Thursday. Strong winds and lake effect snow will linger longest over the Lake Superior shoreline east of Marquette, perhaps into early Thursday afternoon.
