Published: August 18, 2025 | Category: Weather / Chicago

Chicago is heating up — and it’s not just the temperature. A Severe Thunderstorm Watch is in effect across much of the area until 6 p.m., as a wave of potent storms heads this way. Get ready for gusty winds, hail, and potentially sharp downpours.

Storm Timeline

  • Early afternoon (12–3 p.m.): Isolated downpours may begin stirring.
  • After 3 p.m.: Scattered thunderstorms expected to move in with force.
  • 6–10 p.m.: Most pronounced threat window — damaging winds, heavy rain, sudden flooding.

National Weather Service highlights potential for straight-line wind damage and even brief tornadoes. Hail is possible—especially in stronger cells. Combine that with hot, humid conditions (temps near 90 °F and heat index hitting 100+), and the atmosphere is primed to punch hard.:contentReference[oaicite:0]{index=0}

How to Stay Safe

  • Keep an eye on weather updates after 5 p.m.
  • Avoid low-lying zones prone to flash flooding.
  • If you see hail or suspect wind damage, seek sturdy shelter indoors.
