Warm-up to follow cloudy and cool weekend

|

Sluggish low pressure meandering across the southern Midwest played an instrumental role in bringing cloudy and cool weather to the Chicago area this weekend. Persistent cloudiness made sunshine a no-show Saturday, and after a dreary morning, the city managed to eke out less than 20 percent of possible sunshine on Sunday thanks to some breaks in the clouds during the afternoon.
Another batch of low cloudiness and even some fog in outlying areas should blanket the area Monday morning, but a generous dose of afternoon sun should allow temperatures to climb into the 80s, along with increasing humidity. Highs could even hit 90º Tuesday, though more clouds and possible thunderstorms could keep many area readings in the 80s.
After peppering the Chicago area with rain the past few days, showers stayed south of the area Sunday. Several weak “cold-air” type funnels were sighted in central Illinois, but none touched down.
