      Arctic front triggers wind chill warning for western Upper Peninsula

      Wind chill advisories carry us until 10 a.m. EST Wednesday morning for the western half of Upper Michigan. Temperatures across Upper Michigan have fallen into the single digits/teens below zero this morning. But factoring in breezy west winds and it feels more like twenty to thirty below zero in the west. Those steady winds will also create drifting/blowing snow and visibility restrictions through the Keweenaw Peninsula and along the Superior shoreline east of Marquette. Some limited lake effect snow is expected early. But conditions are somewhat dry for now.

      Not much improvement is expected during the day Wednesday. Daytime high temperatures are only expected to reach single digits across a large portion of west/central Upper Michigan. Itâ??ll be warmest south and east to around ten degrees/low teens.

      A new arctic front will drop in out of Canada by Wednesday afternoon and evening. Expect increasing southwest winds ahead of that front. Peak winds to 30-40 MPH will continue to create drifting/blowing snow and reduced visibility along those exposed portions of Upper Michigan through the Keweenaw Peninsula and along our Superior shoreline.

      Snowfall will be kept in check Wednesday night into Thursday. New snow will only amount to an inch to two inches along roughly the northern half of Upper Michigan. However, gusty winds and blowing snow will create white out conditions, especially through the Keweenaw Peninsula and near the Lake Superior shoreline. Visibility into Thursday morning will be reduced to a quarter mile or less.

      In addition, bitter cold temperatures and gusty winds will combine to bring wind chill readings as cold as 30 to 40 below zero Wednesday night and Thursday morning. Exposed skin can become frostbitten in less than 30 minutes under these conditions.

      Wind Chill Warnings will be effective from 3 a.m to noon EST Thursday for Ontonagon, Gogebic, Houghton, Keweenaw, Baraga, Iron, Dickinson and Marquette Counties. Wind Chill Advisories become effective from 6 a.m. to noon EST Thursday for the eastern half of Upper Michigan.

      A Winter Weather Advisory will also be effective from midnight to 11 a.m. Thursday for Northern Houghton and Keweenaw Counties. Meanwhile Alger, Luce and Northern Schoolcraft Counties will be under a Winter Weather Advisory from 2 a.m. to 3 p.m. EST Thursday. By the time we get through this week, we may have broken temperature records that have been in place since the early 1900s!
