Low pressure over northern Illinois will drift east through the weekend, accompanied by showers and cooler temperatures beneath a broad upper-level disturbance. Vertically stacked low pressure will become nearly stationary over the central Great Lakes, resulting in persistent cloudiness into Monday.
After a lull in the showers Sunday morning, areas of rain will develop by afternoon and continue Sunday night, especially north of I-70, along with breezy and cool temperatures in the 50s.
Clouds will linger on Monday, with a few early showers, before skies begin to clear late in the day. Seasonably cool weather and partly cloudy skies will prevail through the week. High pressure midweek will direct northwesterly winds into Ohio, lowering temperatures to the upper 30s in the mornings and holding afternoon readings to the 50s.
