A soaking rain is on the way to the Mississippi and Illinois Valleys late Tuesday night through Wednesday night. Many hometowns could easily pick up over an inch of rain.
That’s a given, but here’s where it gets interesting.
The storm will track to south of the Quad Cities and that’ll set up a cold, brisk east-northeast wind of 20-40 miles-per-hour.
This will keep temperatures in the low-to-mid-40s Wednesday. However, this also sets up the potential for even colder air to spill down closer to the surface.
If that happens, the rain could change over to snow in some hometowns. If it comes down heavy enough, it could overcome the warmer, wet ground and begin to accumulate!
This situation will have to be closely watched. The bottom line is that parts of northern Illinois, including areas in and around the Quad Cities, could see accumulating snow.
But, I think the heaviest of the snow will be downwind of Lake Michigan toward Chicagoland and northwestern Indiana.
This winter, we’ve picked up 22.4″ of snow officially in the Quad Cities. That’s 8.5″ below average for this point in winter. At this time last winter, we were at 24.1″.
I’ll continue to monitor the snow threat and keep you updated.
If you don’t like snow, we’ll be in the 60s and 70s for the weekend.
