Our First Winter Storm: What To Expect

Let me start off by saying this forecast can still change a little, but no matter what happens, the weather is going to create plenty of problems Wednesday night and Thursday, possibly even into Friday.

Model runs are coming into agreement that Thursday's winter storm will stay just to our south. I've outlined what to expect the next couple days with our Winter Storm Impact Forecast.

Things kick off Wednesday with evening showers. A few snowflakes will mix in as we go through the night. There's even enough energy in the atmosphere that we could get a rumble of thunder early on.

That rain/snow mix eventually switches over to all snow on Thursday. When it switches will determine how much snow we get. The National Weather Service is expecting our precip to be all snow by late morning, although the timing could be off by a few hours.

Now the big question... how much snow? Initial forecasts are showing heavier amounts staying to our northwest, but we are really close to getting some big snow totals. Right now, I'm going 4-6" in the Rockford Metro, with heavier amounts to the northwest.

Effective Wednesday Night and Thursday
The biggest concern with this system will be Thursday night into Friday, as winds gusts are expected to pick up somewhere in the 40-50mph range. Because this is going to throw a lot of snow around, the National Weather Service has issued WINTER STORM WATCHES for most of the Stateline and WINTER STORM WARNINGS for Jo Daviess County and all of southern Wisconsin.

If this storm moves, even a little bit, it could impact snow totals, but the strong winds are coming regardless, so be careful if you're doing any traveling the next couple days!

More updates as we get them! -BA
