CHICAGO (CBS) -- Increasing clouds tonight, but dry. Lows will be in the low to mid 30s. 

Cloudy and dry to start Saturday, then numerous showers move in from the west by midmorning. Wet snow mixed with rain is possible, but mainly for areas north and northwest of Chicago. Little to no accumulating snow is expected, but up to a third of an inch of rain is possible. Highs will only reach the low 40s on Saturday. Rain chances come to an end Saturday evening.

For Sunday, sunshine in the morning, then increasing clouds in the afternoon. Highs will range from low 40s along the lake to low 50s inland. Shower chances return Sunday evening and linger through at least the first half of Monday.

Overall another unsettled weather pattern is expected for next week with rain chances and highs in the 50s. A few rumbles of thunder will be possible on Wednesday, but the best chance for strong storms looks to remain south of the area at this point. Light showers possible for Thursday for the Cub's Home Opener.
