Winter Storm Watch issued for Wednesday into Thursday across SE Michigan

A Winter Storm Watch has been posted for all of SE Michigan for Wednesday afternoon through Thursday afternoon.

The next 36 hours will be tranquil and pretty close to normal for late February temperatures, but a big dose of winter is headed our direction for Wednesday and Thursday. This storm will have a big impact on drivers starting with Wednesday’s afternoon commute through both drives on Thursday, but some big questions still exist when it comes to snowfall amounts.

Let's get the easy stuff out of the way first. Tonight, skies will be mostly clear. Temperatures will drop to the mid 20s for lows.  Tuesday will be dry and slightly milder as highs reach 40 degrees under partly cloudy skies.

Then we get to the meat of the forecast. Wednesday morning rain will start falling at the Ohio state line just after daybreak. That precipitation will gradually spread north through the morning, continuing to rain on the east side, and all snow in our western areas. Obviously the exact location of that line is still up in the air. At some point late Wednesday night, the colder air will win out and all areas will see snow. That snow will continue through the day on Thursday leading to accumulations that should look like this:

Some newer data is suggesting that temperatures may be even warmer than what we’re expecting. I want to see a couple more model runs before I jump on that bandwagon however. So we’ll break down the numbers coming up tonight on Local 4 News at 11. No matter where that rain/snow line sets up, I’m highly confident that all three commutes during this storm (Wednesday PM, Thursday AM/PM) will be a headache… especially the ones on Thursday. So plan ahead.

The rest of the forecast will be dry and close to average into the weekend and early next week.
