The bad news: The weather system that wreaked havoc across Iowa, Nebraska, and South Dakota yesterday will hit Chicago today. The good news: We aren't going to get the 37 inches of snow that fell in Lead, S.D. Friday.

A cold front heading into the region from those points west will start to bring down some of the warm temperatures we've seen lately, spawning scattered thunderstorms as it does so, according to ChicagoWeatherCenter.com. That heavy weather hit this afternoon and is expected to continue into the evening.

As of 4:04 p.m., the severe thunderstorm warning in effect for portions of Cook, DuPage and Lake counties expired, according to the Chicago Weather Center. Officials reported some flooding, high winds and hail in the metro area.

Officials also reported wind gust up to 40 mph in Arlington Heights, flooding in Kankakee and Chicago, as well as pea size hail in Oak Brook.

The National Weather Service says that high winds, some possibly above 60 m.p.h., is the "primary severe threat" from this storm system, along with the possibility of heavy rain, some hail and lightning.

The rain is expected to leave overnight, ushering in several days of cooler weather with highs in the upper 50s or low 60s and lows in the low 40s. Scattered showers are also in the forecast for Monday and Tuesday.

The sun is predicted to come back on Wednesday, with temperatures peaking in the upper 60s and low 70s.
