Ice Storm Warning this weekend

A Winter Weather Advisory has been issued for the remainder of the NBC25 viewing area.

The National Weather Service has issued an Ice Storm Warning for Shiawassee, Genesee, Lapeer, and Sanilac counties.

The Warning takes effect at 5pm today and lasts through 7am Sunday.

A wintry mixture of snow, sleet, and freezing rain will develop in these areas by mid-afternoon, and change to primarily freezing rain overnight.

The rain could be moderate or even heavy at times, creating a coating of ice on roadways between a quarter and a half-inch thick -- especially along and south of I-69.

Although the heaviest ice is expected along and south of I-69, a layer of ice mixed with some sleet and snow will still be thick enough to make travel extremely difficult or impossible in northern sections of the above counties as well.

Also, the ice will be thick enough to snap tree branches and lead to downed power lines.

Therefore, be prepared for the possibility of power outages late tonight and tomorrow morning.

Also, the National Weather Service has issued a Winter Weather Advisory for the remainder of the NBC25 viewing area, including the Tri-Cities and Thumb, from 7pm tonight through noon Sunday.

In some of our western counties -- including Gratiot -- the advisory actually goes from 4pm today through noon tomorrow.

For our northern counties -- including Ogemaw, Gladwin, Arenac, and Iosco -- the advisory actually goes from 1am to 7pm Sunday.

For Clare and Isabella counties, the advisory goes from 7pm tonight through 7pm Sunday.

In these areas, a mixture of sleet, snow, and freezing rain will make travel dangerous from this evening through tomorrow morning.

In addition, snow and sleet will accumulate to 2-4" Sunday morning into the early afternoon in many of these areas as colder air changes the mix to mostly snow and sleet for the latter part of the Advisory period.

Some areas north of Standish could see more than 4" of accumulation.

Also, a period of moderate freezing rain is possible in sections of Saginaw, Gratiot, and Tuscola counties between 2am and 7am which could lead to more substantial ice accumulations in these areas.
