First day of summer in Chicago brings near-record heat and threat of severe weather – NBC Chicago

The summer solstice brought warm temperatures back to the Chicago area, with near-record heat possible.

After a few days of cooler temperatures, Tuesday’s highs are expected to hit the 90s, but an excessive heat warning will stay away due to low humidity.

In the city itself, the high temperature forecast for O’Hare is expected to reach 99 degrees, which would be just below the record high of 101 degrees set in 1988.

While the heat will be well above normal, the good news is that last week’s oppressive humidity won’t return this week – at least not yet. The only place in the Chicago area currently under some sort of heat advisory is in Kenosha County, where those readings could potentially hit 105 degrees, according to the National Weather Service.

According to the Storm Prediction Center, there’s a marginal chance of severe weather — that’s level one in five — in the Chicago area, starting around 8 p.m. Tuesday, with the main threats damaging winds and hail the size of a penny.

Heat-related illnesses can strike quickly when the mercury soars, and there are specific symptoms that experts say you need to watch out for during periods of scorching weather.

If you must be outdoors for a while, watch for signs of heat stroke and heat exhaustion.

Here are the signs of heat stroke to look out for:

  • An extremely high body temperature
  • Dizziness and nausea
  • Throbbing headaches, strong and rapid pulse
  • Red, hot and dry skin
  • Irrational behavior
  • rapid breathing

According to doctors at Rush University Medical Center in Chicago, here are the signs of heat exhaustion to watch out for:

  • Low blood pressure
  • Dehydration
  • Extreme weakness
  • Fainting or lightheadedness
