A cool, rainy night is on tap for Chicago.
The Jet Stream turning the winds off Lake Michigan is bringing showers and thunderstorms into the area that should last through the night.
Some severe storms are possible south of the city as the rain remains throughout the entire area into Friday morning.
Lows will dip down into the lower to middle 60s with winds at around 10 to 20 mph.
The rain pushes eastward by Friday afternoon, but the chance for storms remains throughout the earlier hours. Winds are expected from the north from 15 to 30 mph.
The weekend outlook appears much drier. A seasonal Saturday sees mostly sunny skies, high temperatures in the upper 70s and low humidity levels. Sunshine mixes with more clouds Sunday with afternoon highs in the low 80s and rising humidity levels.
Another round of showers and storms is expected to crop up Sunday night through the morning hours.
