Meteorologists blame thunderstorms for Friday's cooler weather

It looks like Chicago residents won't be experiencing the scorching heat meteorologists were predicting all week.

Richard Castro, meteorologist with the National Weather Service, blames thunderstorms for the cooler temperatures.

"That's one of those things -- it looks like the entire week we're in line for a spike of extremely hot temperatures today along with humidity, and then thunderstorms -- the fact they've persisted so long really threw a wrench into the idea of how hot it would be," he said.

Chicago may see wind gusts of up to 30 mph on Friday. Castro said things should gradually warm up, but the National Weather Service has canceled a heat advisory.

The National Weather Service is predicting temperatures in the lower 90s for Saturday, and there might be some storms. As for the rest of the holiday weekend, temperatures are estimated to hit between the upper 70s and lower 80s.

When asked if this meant residents can't always count on their weathermen, Castro laughed.

"We work as hard as we can to stay up with things but sometimes, as advanced as our technology is, things still surprise us," he said.
