      Lake Effect Snow Warnings continue for portions of Upper Michigan

      A Lake Effect Snow Warning is effective for Ontonagon County until 1 pm Thursday afternoon. Houghton and Keweenaw Counties will also continue the Lake Effect Snow Warning until 7 pm tonight.

      Meantime, Lake Effect Snow Advisories continue for Alger and Luce Counties until 7 Thursday night as west-northwest winds keep steady lake effect snow falling in those areas.

      Impressive snowfall amounts were observed across the western Upper Peninsula on Christmas Day. 16.5â?? of new snow were reported in Silver City in Ontonagon County.

      Snow has been piling up east of Marquette as well. 3â?? of new snow has fallen in the past three hours in Grand Marais, with more on the way. Expecting roughly 5-9â?? of new snowfall in the areas mentioned above. However, heavier snow bands could produce up to a foot of new snow into this evening along the Superior shoreline, towards Whitefish Point.

      Elsewhere, high pressure moves into the area, allowing patchy blue sky to break out between mid and high level clouds.

      Partially clearing sky conditions and light winds combine to make for a cold Thursday night/Friday morning. Coldest temperature readings will be seen across the interior west with lows dipping several degrees below zero. Wind chill readings are expected to fall to -15 in the coldest portions of the western interior. The rest of Upper Michigan will also be plenty cold by Friday morning with overnight lows falling through the single digits.

      Warmer air will provide a brief break from the bitter cold as we look into the weekend. Afternoon highs Friday are expected to reach into the mid & upper 20s. Saturday will see highs in the low 30s and many places may break above freezing. There does appear to be enough moisture to spark a few snow flurries. And although the precipitation type is expected to remain as mainly snow, there may be some freezing drizzle/freezing rain Friday into Saturday.

      An impressive arctic blast is expected to bring bitter cold temperatures and lake effect snow to finish out what has been a decidedly cold 2013.
