Midweek rain, cool down to mar a mild week

|

Overall, the upcoming week in Chicago will be quite springlike with inland temperatures away from Lake Michigan’s chilly breezes pushing to 70° or higher Sunday and Monday, and again by week’s end.
However, in the interim, a sluggish storm system meandering through the central Midwest to the south of Chicago will bring this area a steady diet of clouds, rain and east winds—providing a temporary setback to the rapidly advancing spring season. Inland readings may drop 20 degrees or more from Sunday’s mid 70s to Wednesday’s middle 50s before rebounding back to the 70s by Saturday as winds return to a southerly direction.
Though the storm’s southern track will bring the Chicago area a damp chill, it will serve to keep severe weather here at bay, confining the most active storms to areas further south—closer to the warm, moist Gulf air needed to fuel the severe thunderstorms.
