As forecast for much of this week, measurable snow is expected to spread over parts of the Quad-City Area later Friday night through much of Saturday. Because of that, a Winter Weather Advisory is still in effect starting tonight.
Timing: Light to moderate snow will move into southeastern Iowa and west-central Illinois later this evening, then spread further north and east overnight into Saturday morning. The whole system to push out of the area later on Saturday evening.
Amounts: The most snowfall is expected along and south of Highway 34. This is where as much as 5-7 in. could accumulate. Around 3-5 in. is expected between Hwy. 34 and I-80, including in the metro Quad Cities. Lesser amounts are expected farther north.
Impacts: Because all of the precipitation will be snow, roads are mostly pre-treated now, which should make driving less treacherous. Winds will also be fairly light, reducing the threat of blowing/drifting snow and low visibilities. All in all, we’re just looking at a run-of-the-mill wintertime snow event.
