Don't be fooled by last week's sunny warmth. The down side of summer weather heads to Chicago this week, bringing rain, thunderstorms and possibly isolated tornadoes.
Saturday night looks to remain dreary and cool, but the rain will most likely hold off until Sunday. Temperatures will stay in the 60s in most of the Chicago area, but areas near the lake can expect to see temperatures in the 50s as a cold front moves in.
The first thunderstorms will hit the Chicago area Sunday morning, but severe weather isn't expected.
The second round of storms will arrive Sunday night and Monday morning. These storms have the potential to bring severe weather, including damaging winds, heavy rain, large hail and lots of lightning.
Isolated tornadoes are also possible Sunday night and Monday morning, but the risk remains slight for now.
The rest of the week is expected to be dry with temperatures in the in the 60s and low 70s.
