Chicago Weather Alert: 110°F Heat Index Today, Severe Thunderstorms Likely Tonight

Stay safe Chicago! A dangerous heat wave is gripping the city today, with a heat index soaring to a scorching 110°F (43°C). This extreme heat poses significant health risks, prompting urgent warnings from the National Weather Service (NWS). But the sweltering heat isn't the only weather concern; severe thunderstorms are expected to roll in tonight, bringing the potential for damaging winds, hail, and heavy rainfall.

Dangerous Heat: Take Precautions Now

The NWS has issued an Excessive Heat Warning for the Chicago metropolitan area, urging residents to take extreme caution. The combination of high temperatures and humidity will create a dangerously high heat index, making it easy to suffer from heat exhaustion or heatstroke.

Here's what you need to know to stay safe:

• Stay Hydrated: Drink plenty of water throughout the day, even before you feel thirsty. Avoid sugary drinks and excessive alcohol consumption.
• Limit Outdoor Activities: If you must go outside, do so during the coolest parts of the day (early morning or late evening). Take frequent breaks in shaded or air-conditioned areas.
• Check on Vulnerable Populations: Pay special attention to elderly individuals, infants, young children, and those with chronic health conditions who are more susceptible to heat-related illnesses.
• Wear Light Clothing: Loose-fitting, light-colored clothing will help you stay cooler.
• Never Leave Children or Pets in a Parked Car: Temperatures inside a parked car can rise rapidly, even on a mildly warm day. This is especially critical during extreme heat.
• Know the Signs of Heatstroke: Symptoms include high body temperature (above 103°F), confusion, rapid heartbeat, and seizures. Seek immediate medical attention if you suspect heatstroke.

Severe Thunderstorms Expected Tonight

While the extreme heat will be the primary concern today, a significant weather shift is anticipated tonight. The NWS forecasts a high probability of severe thunderstorms, capable of producing damaging winds exceeding 60 mph, large hail, and torrential rainfall.

Prepare for the Storms:

• Stay Informed: Monitor weather reports closely throughout the day and night. Download a reliable weather app and sign up for weather alerts from your local authorities.
• Secure Loose Objects: Bring any outdoor furniture or decorations inside to prevent them from becoming airborne during the storms.
• Charge Your Devices: Ensure your cell phones and other electronic devices are fully charged in case of power outages.
• Have a Plan: Know where you will go if you need to seek shelter during the storm.

This combination of extreme heat and the threat of severe weather necessitates careful preparation and vigilance. Staying informed and taking the necessary precautions will help you and your family stay safe during this challenging weather event.
