1 Inch of Snow? Quad Cities Could See Slippery Roads Along I-80

If you’re enjoying today’s mild weather, don’t get too comfortable just yet. The Quad Cities are in for a quick shift this week, with strong winds, a chance for accumulating snow, and then a fast warm-up right after.

According to the US National Weather Service Quad Cities, south to southwest winds will be the first thing people notice. Gusts today could reach up to 40 miles per hour, making it feel much breezier than the thermometer suggests. Those winds also increase fire danger, especially in dry areas. High temperatures today will vary a lot depending on location, ranging from the mid-30s in northern areas to the lower 50s farther south.

Gusty Winds Today Before Colder Air Moves In

By midweek, colder air settles back into eastern Iowa and northwest Illinois. Wednesday’s high temperatures are expected to range anywhere from 26 to 46 degrees, depending on where the cold air sets up. That temperature spread is important, because it will help determine who sees rain and who sees snow later on.

Forecasters say the biggest concern arrives Wednesday night, when a developing weather system moves through the region.

Snow Possible Wednesday Night, Especially Near I-80

Current projections show rain changing to snow Wednesday night into early Thursday. Some spots could see around 1 inch of snow, though officials stress that the exact location of that accumulation is still uncertain. The storm track has been trending slightly south, which could bring snow closer to the Quad Cities metro.

If snow does fall, travel impacts would most likely be felt along I-80 near Davenport, I-74 through Moline, US-30 near Clinton, and I-280 around the Quad Cities. Late Wednesday commuters and early Thursday morning drivers should be prepared for slick roads if temperatures drop fast enough.

Overnight lows could fall into the upper teens and 20s, allowing any moisture on roads to freeze.

Big Warm-Up Coming to End the Week

The good news? This wintry weather won’t last long. By Thursday and Friday, temperatures rebound quickly, climbing back into the upper 40s and even the mid-60s in some areas. That warming trend should melt any snow that does manage to accumulate.
