A snow event is still on the way to Illinois Saturday afternoon and Saturday night. However, our part of northwestern Illinois will likely miss out on the brunt of the accumulating snow.
The afternoon NAM model takes the low pressure system across Arkansas and Kentucky on its way to Ohio. This would keep the heaviest snow southeast of the Quad Cities.
NOAA’s GFS model is falling in line with that, too, and takes the storm on a similar path.
While we’ll still see some snow in the Quad Cities Saturday and Saturday night, accumulations look to be on the light side.
Here is a map that my colleague, Andy McCray, put together showing where you’ll see the heavier snow (several inches).
Keep in mind that the path of the storm could change again Friday or Saturday. So, if you have travel plans, check the latest forecast before the snow event.
I’ll have an update, plus snow projections, on “Local 4 News This Morning” Friday from 5-7 a.m.
One thing that’s certain is that the coldest air of the season arrives Saturday night into next week.

If you’ve been watching me on “Local 4 News This Morning” in the Quad Cities this week, you know I’ve warning you about the coldest air of the season that’s heading our way Sunday into next week.
Before that arrives, mild temperatures and rain will have us checking the calendar twice to make sure it’s actually January.
In the transition between highs in the 40s on Friday and highs in the teens Sunday and next week, a low pressure system will move from the southern Plains into the eastern Great Lakes Saturday.
The way it looks right now, moderate snow will develop during the day Saturday into Saturday night. The heaviest snow will fall across Illinois with several inches of snow in or near the Quad Cities.
While the storm is still off the Pacific coast and we can sample weather data better when it’s onshore, you’ll definitely want to keep up on the latest forecast later today and Friday.
Once computer models get a better grasp of the intensity of the storm and the path it’ll take, this axis of the heaviest snow could shift west into Iowa or east into Indiana.
