Snow back in the forecast on Wednesday, followed by very frigid air the rest of the week

The coldest air of the season is on the way, with some spots struggling to reach above zero on Thursday.{ }

A Winter Weather Advisory is in effect for Charlevoix, Antrim, and Kalkaska counties until 7PM Wednesday evening. Expect lake effect snow to around most of the day, with upwards of 2-5 inches of snow accumulating in spots. This will lead to reduced travel and visibility throughout the day.

A Winter Weather Advisory is in effect for Grand Traverse and Wexford counties until 7AM Thursday morning. Expect lake effect snow to hang around all day and continue into tonight, with upwards of 2-5 inches of snow today and another 1-2 inches tonight in spots. This will lead to reduced, if not difficult, travel at times and visibility throughout the day.

A Winter Weather Advisory is in effect for Leelanau, Benzie, and Manistee counties until 7PM Thursday evening. Expect lake effect snow to be consistent today and into most of Thursday with upwards of 2-5 inches of snow today and another 2-3 inches tonight/Thursday in spots. This will lead to reduced, if not difficult, travel at times and visibility through tomorrow.

A Wind Chill Advisory is in effect for Chippewa-Mackinac-Presque Isle-Otsego-Montmorency-Alpena-Crawford-Oscoda-Alcona-Roscommon-Ogemaw-Iosco-Emmet, and Cheboygan counties from midnight tonight until noon Thursday. Dangerous wind chills will drop as low as 30 below zero, which can lead to frostbite in little as 10-15 minutes.

A low pressure system passing through the Great Lakes on Wednesday will crank the lake effect machine back up, and will be followed by the coldest air of the winter so far.

As the low pressure system and associated cold 'arctic' front pass through northern Michigan by midday Wednesday, winds will shift from the west-southwest to the north-northwest. Lake effect snow will be across most of the NW Lower Peninsula for the first half of the day, before becoming more concentrated to the Grand Traverse Bay region and Lake Michigan shoreline by the end of the day as the winds shift. For everyone else, light snow amounts will be associated with the cold front passage. High temperatures on Wednesday will range from the upper teens to the lower 20s (which will be warm compared to the rest of the week).

For Wednesday night, very cold air begins to spill into the Great Lakes. This, combined with skies clearing across the inland areas of both the Upper and Lower Peninsula will plummet temperatures overnight. Low temperatures will fall into the negative single digits to negative teens for majority of the viewing area - the exception will be west of US-131, where lows will fall into the positive single digits. Lake effect snow will continue for those closer to the Lake Michigan shoreline as well.

Thursday will be cold, with some spots not even reaching above zero (this will be most common in the interior spots). Overall, the range in high temperatures tomorrow will be from the negative single digits to the lower teens. Wind chills will be even colder, leading to dangerous conditions outside. Lake effect continues mainly along and west of US-31.

This cold air will continue into Friday and Saturday, with a slight warming trend by the end weekend. Temperatures will climb into the 20s by Sunday, but will lead to another chance of widespread snow.
