Stay hydrated. Thursday may be a scorcher.
A heat advisory goes into effect in the Chicago area starting at noon Thursday until 8 p.m. Temperatures threaten to break the 101-degree record set in 1952 with highs between 100 and 105 degrees.
Increasing humidity will make it feel like 105 degrees to a whopping 110, according to the National Weather Service.
There is a chance thunderstorms will pop up in the afternoon hours, but Chicago won't feel much relief from the heat.
The temperature reached 92 degrees about 4 p.m. Wednesday, but was well short of the record high for June 27 of 101 degrees set in 1971, according to the weather service.
Temperatures are expected to hold in the low- to mid-90s through the weekend.
The heat puts more pressure on an area already dealing with drought-like conditions. Chicago saw only a half-inch of rain in June, about 2.5 inches less than usual.
Orland Park and Orland Hills are among multiple suburbs with odd-even watering restrictions in affect, and some Fourth of July fireworks displays could be in jeopardy if rain doesn't come.
Tinley Park as a precaution rented 4,000 feet of irrigation pipe and 118 sprinklers to saturate the grass where the fireworks will land. Current dry conditions could create a fire hazard, officials said.
"We were considering canceling the fireworks, but we said we want to prevent that from happening, so we rented the irrigation system," said Park and Recreations Director John Curran. "This time we did it a couple weeks in advance and said, 'We're going to be well-prepared.'"
