Light snow showers will develop in eastern Iowa before sunrise on Monday. The snow showers will continue to develop and push east into northern Illinois and southern Wisconsin throughout the morning. Even though this system is very limited with moisture, minor snow accumulations are likely. Precipitation estimates remain below one-tenth of an inch. The result will be light coating of snow, perhaps up to an inch in spots. South of Interstate 88 may only see a dusting.
The intensity of the snow will be light, but a quick burst of moderate snow is not out of the question. With a brisk southwest wind—sustained between 10 and 20mph and gusting up to 30mph—there may be some short-lived visibility issues. Also with gusty wind comes the concern of blowing snow. Although the accumulations will be minor, blowing snow may cause icy patches on some roads. High temperatures will reach the lower 30s by Monday afternoon while any lingering snow showers should clear the area by then, if not sooner. Patchy (freezing) drizzle may develop late afternoon and early evening in advance of an approaching cold front.
