Snow is on the move and it's heading right for Northern Illinois. Luckily for the Stateline, we'll escape the more hefty snowfall totals but will still see some accumulations across the area. Snow moving from the south will enter our region as we go through the afternoon.
By the mid-afternoon hours, 3-4 p.m., snow will gradually begin moving into the region moving north. Areas south of Rockford will see the snow first. These are also the areas I expect to have, if anything, the most impacts for tonight's commute purely because it will have been snowing in those areas longer.
I'd expect some slow downs and quick reduced visiblities at times. There could be some slushy conditions on the roads too, as this snow will fall as the heavy and wet type of snow. Overall, just take it slow out there and allow for some extra time!
That same snow will gradually move north and overspread the rest of the region later this evening and into the overnight hours. Notice that there are no Advisories, Watches or Warnings in effect for our region as those are just south of us.
Snow will fall, sometimes in heavy rates at times overnight into the very early hours Thursday. When all is said and done, most of us will see between 2-3" of snow. Areas west of Rockford closer in Jo Daviess and Stephenson Counties may get only around 1" or so. There could be a few pockets south and east of Rockford that could see isolated amounts near 4" but those totals will be closer to the Chicago area.
The bigger story is what comes after the snow. Beginning Thursday morning when the snow begins to taper off, temperatures will begin to drop. Not to mention that some of the snow that falls overnight will be finish off as lighter and fluffy. This means that on Thursday morning, there is a slight renewed chances in seeing some blowing snow. All of this would be taking place near the Thursday a.m. commute.
High temperatures Thursday will only be in the teens with clearing skies in the later morning hours. Once Thursday night comes around, that's when temperatures will get near 0° and wind chill values will drop below that. At times late Thursday night through Friday morning, wind chills will be between -10 and -20°. This is when you'll need to bundle up appropriately.
With wind chill values that low if you're outside for too long with exposed skin, frostbite can occur in as little as 25-30 minutes. If you are going to be outside for a good amount of time, here is how you can dress for the cold.
1. Keep head warm with a hat
2. Cover face with mask or scarf
3. Wear several loose-fitting and warm layers
4. Coats are a must, especially tightly woven and water repellent ones
5. Mittens are warmer than gloves
6. Wool socks and waterproof boots are good to keep feet warm
Temperatures will begin to rise mid-day on Friday and we'll quickly rebound into the 30's and even 40's by this weekend and early next week.
