An arctic cold front is moving through Michigan this afternoon and evening. The cold front will bring bitter cold, strong gusty winds, and a burst of snow.

The sharp drop in temperatures could cause roads to re-freeze quickly this evening, so be ready for quickly changing road conditions.

The top graphic shows the temperatures at 6 p.m. tonight. Detroit will still be in the upper 20s, but temperatures will fall off rapidly going northwest. Grand Rapids should be down to 19 degrees by 6 p.m., while the western U.P. will have dropped below zero.

Here is the current radar showing snow moving across Lower Michigan.

The arctic cold front will also bring all of Lower Michigan a period of snow showers this afternoon and evening. The snow won't be as heavy as the snow early this morning, but it will be a colder, wind driven snow. So this snow will cover over the roads and freeze the roads this evening. Most areas I'd expect only another one to two inches in the afternoon and evening burst of snow.

This is a wind forecast for 6 p.m. tonight, Sunday, January 4, 2015. Northwesterly winds will be picking up into the 15 to 25 MPH range. The shoreline of West Michigan could be especially nasty with gusts over 30 MPH.

Wind will increase greatly

The final graphic shows the increase in wind expected at 6 p.m. this evening. Most areas will have a 15 to 25 MPH wind by 6 p.m. tonight. The shoreline areas of West Michigan could have wind gusts close to 40 MPH this evening.

So travel conditions are going to deteriorate this evening when snow showers, wind, and cold all gang up on Michigan.

We better get used to this type of winter weather. It looks like winter is coming back with a vengeance all this week.
