In the wake of a vigorous winter storm, cold temperatures and a brisk breeze will usher in another round of lake effect snow for the Great Lakes.  Some areas have already seen well over a foot of snow. https://twitter.com/NWSGrandRapids/status/1194266205902667776 WeatherNation meteorologist Joe Astolfi explains how the process of lake effect snow works. https://youtu.be/iPAwyoSDYh8 . Favored locations downwind of Lake Superior and Lake Michigan---known as the snowbelt---can expect localized bands of persistent snowfall into this evening.  Squalls will be narrow but intense at times.  Expect quick changes in visibility and road conditions if you need to travel in the alert areas. https://twitter.com/NWSMarquette/status/1194584919697018880 https://twitter.com/NWSGaylord/status/1194632090047762432 Some communities in Michigan's Upper Peninsula may pick up another 6" to 12" of snow!  In west Michigan, another 3" to 6" is possible.  A storm system moving in from the west coupled with lake interaction will enhance snowfall Thursday into Friday morning.  Travel may be hazardous for the morning commute. https://twitter.com/NWSGrandRapids/status/1194565509217423360 If you're joining us from cities in the Great Lakes region, make sure to stay up to date with WeatherNation for the latest forecast.  Looking ahead, warmer weather will return by the end of the week and bring an end to the lake effect snow. Stay warm and stay safe!  For WeatherNation, I'm Meteorologist Joe Astolfi.
