A heat advisory has been issued for the Chicago region as temperatures could climb Thursday to a record-breaking 100-degrees-plus.

The advisory goes into effect at noon and remains into place until 8 p.m., according to the National Weather Service’s Chicago office.

The weather service estimates that Thursday’s high could range from 100 to about 105 degrees, and the heat index could hit up to 110 degrees.

The all-time high for June 28 is 101 degrees, which was set in 1952.

Chicago has had 14 days reach the 90s this year so far, with May 27 being the warmest day at 97 degrees.

Prolonged exposure to the heat and physical activity could lead to sunstroke, heat cramps and heat exhaustion if the proper precautions are not taken, the weather service said in a statement.

Wearing light and loose fitting clothing, drinking plenty of water and rescheduling strenuous activities to the early morning or evening can help reduce the risks of sunstroke, heat cramps and heat exhaustion, the weather service said.

Hot weather may not seem as dire as an impending hurricane, but it can be. For those with no air conditioning, this presents a problem.

Heat causes more fatalities in the United States than any other weather event, according to the National Weather Service, killing more people annually than floods, lightning, tornadoes and hurricanes combined.

Chicago-area residents should find that cool spot and make themselves at home for the long haul.

Meteorologists in the Romeoville office of the National Weather Service are predicting a steady stream of dry, hot air blowing through for the next week, possibly even for the rest of the summer.

For the time period of May through June 25, Chicago is tied with 1911 for the hottest average temperatures, said meteorologist Stephen Rodriguez. It has been the ninth warmest June in Chicago.

A dome of hot air that has been “cooking” the Midwest will settle overhead, hiking temperatures to the mid-90s, Rodriguez said.

On Thursday, it could reach 100 degrees.

A weak cool front will bring some relief by Friday, but it will still be in the 90s Friday through early next week.

There is only a slight chance of rain Thursday night through the weekend.

“The relief on Friday will come in terms of humidity, some drier air trying to work its way in,” Rodriguez said.

Temperatures could continue to be above normal for the next three months, with precipitation below normal, he said, according to the one- to three month outlook.
