Chicago will get a brutal heat this week. Temperatures on Tuesday feel like 100 degrees. The National Weather Service says the city might see a historic stretch of 90-degree days in years. The muggy conditions add to the discomfort. Storms could hit and may drop torrential downpours and strong gusts. Forecasters say the storms may last only briefly. Thunder chances rise by evening. Police reported a gunfire incident near East 47th Street early Saturday after a robbery attempt failed. Further information have been released.
