Storm Details

Overnight Update:  Scattered light rain or isolated freezing rain will be possible well south of the turnpike.  Occasional freezing rain (with some snow in spots) will continue across northern sections with additional ice accumulation.

9pm:  Lucas county has been added to the Winter Storm Warning due to the icy conditions.

7pm:  we have received official National Weather Service spotter reports of a tenth to a quarter inch ice accumulation across parts of southern Michigan.

EVENING UPDATE:

There will be a lull in the precip across NW Ohio at times this evening.  Snow has changed to freezing rain in many locations.  Temps will rise a slight amount later this evening, allowing some plain rain across NW Ohio and freezing rain in SE Michigan & near the state line.  Ice accumulation will be a real problem for the northern sections of our viewing area.

This rain will turn back into a mix around daybreak, then back to light snow.  There will be a break in the precip during the day.  Another system will spread another round of snow in late in the day into the night.  A daytime accumulation of 1-2" is possible, with additional accumulations Monday night.

Morning post:

Some snow, or a mix of sleet and snow, will move into the area late this morning into early this afternoon.  A light accumulation of snow and sleet is possible.  The precip will change to freezing rain during the afternoon, and a glaze of ice is likely--especially the northern half of the area.

The precip will turn to non-freezing rain as temps hit the mid 30s by late afternoon or early evening.  Southern Michigan and areas near the state border could see the freezing rain last into the mid/late evening.

We'll have periods of steadier rain overnight with lows just above freezing.  The rain will turn more scattered after daybreak, with colder air returning.  A mix or snow will be around in the morning to midday.

A winter storm warning is in effect for Fulton, Hillsdale, Lenawee, Monroe & Williams counties.

A winter weather advisory is in effect for most everywhere else.
