Bundle up with be the mantra for Chicago-area parade watchers this St. Patrick’s Day. The day will dawn wintry with a period of wet snow that could accumulate an inch or two on grass areas, especially south and west of the city. Sunshine should return by afternoon allowing inland highs to reach the lower and middle 40s, but fresh east-northeast winds will keep readings in the 30s near the lake. Significantly improving weather is on tap for Sunday as temperatures surge into the lower and middle 50s, though onshore winds will keep lake shore areas closer to 40. Current forecasts peg dry weather for Election Day, though a system passing south of the city could brush far south portions of the metro area with some light snow or flurries. Dry, but chilly weather will prevail for the rest of the week, before temperatures moderate in advance of a weekend storm that could bring showers on Saturday.
