Heavy rain, lightning and damaging winds make their way to the Chicago area Sunday afternoon and evening as a storm system moves through the region.
Parts of McHenry, Boone, Winnebago, DeKalb and LaSalle Counties could see numerous severe storms and possibly a tornado or two between 2 p.m. and 4 p.m. The rest of the Chicago area to the east will likely see less severe weather, but the rain, lightning and gusty winds are expected to strike.
As the system moves in, heavy rain, quarter-sized hail, lightning and damaging winds up to 50 miles per hour could arrive. There is a low risk of tornadoes striking the immediate Chicago area, however. The rain and storm system is expected to move out by midnight Sunday.
As the day progressed, temperatures heated up to the low 80s before rain showers were expected to move in. The warm temperatures will stick around through Monday, but they will drop significantly on Tuesday.
The rest of the week is expected to remain dry, but highs will drop to the low to mid 60s on Tuesday, Wednesday and Thursday.
By Memorial Day weekend, temperatures should increase again to the 70s.
