Chicago Weather: Dangerous Heat Sunday, Followed By Possible Storms

CHICAGO (CBS)-- We're expecting some brutally hot weather on Sunday, with potentially dangerous heat and humidity possibly making it feel like it's 100 degrees outside.

It will be mainly clear, warm and muggy Saturday night, with lows in the lower to middle 70s, but Sunday will bring hot and steamy conditions.

Sunday's temperatures will be in the 90's but will feel more like 100 degrees with humidity. Rain returns to the forecast Sunday evening, when thunderstorms and downpours are possible. There is a marginal risk for severe weather for areas in northwest Illinois.

Rain chances linger into Monday, but then we can expect a return to more seasonable warmth next week with highs in the lower to middle 80s.
