8:00 Update: Given current trends to our west and the latest data this evening, we’ve adjusted the forecast slightly. The main band of accumulating snow will most likely set up from the Quad Cities to the southeast.
We’ve also lowered amounts slightly. Isolated areas of up to 2″ of snow are still possible in parts of Knox, Stark, Henry, & Bureau counties in Ilinois.
Original Story: Parts of the QCA will see quick accumulations of snow late this evening and overnight.
A fast-moving area of low pressure will push across Iowa into Illinois tonight, bringing some rain initially, then a brief wintry mix, finally periods of snow.
As of this afternoon, it looks like a band of 1-3″ of snow is possible from around Iowa City & Cedar Rapids eastward into Illinois. The heavier amounts (more toward 3″) will be further into Illinois.
Most of the snow will fall after 10:00 PM and wrap up before Sunday morning.
Brief periods of heavy snow and slippery roads are possible.
