Chicago Weather Alert: Thunderstorms and Rising Humidity Heading to the Windy City

While Friday brought plenty of sunshine and comfortable conditions to the region, the calm is only temporary. Residents tracking the weather in Chicago should prepare for a shift as a new weather system moves in, bringing a mix of severe storms and muggy conditions.

Midnight Storms and Weekend Outlook

According to the latest updates from the NBC 5 Storm Team, strong thunderstorms are rapidly developing over western Iowa. These systems are expected to track toward the city, with the impact hitting the Chicago area between 2:00 AM and 6:00 AM on Saturday.

The National Weather Service (NWS) has warned that some of these storms could become severe. Key highlights include:

n
• High-Risk Areas: Locations west of the Fox Valley are particularly susceptible to localized damaging winds.
• Saturday Morning: Lingering showers may persist until 9:00 AM, though the majority of the day is expected to remain dry.
• Saturday Evening: A slight chance of isolated thunderstorms remains possible.

Sunday Forecast: Warmth and Uncertainty

As we move into Sunday, the temperature will climb into the mid-80s. While the daylight hours should remain mostly dry, there is a possibility of a few additional storms around midday. It will be a great day for outdoor activities, provided you keep a close eye on the radar for any sudden developments.

The Monday Heatwave and Humidity Spike

Looking ahead to Monday, the weather takes a turn toward the “muggy.” A greater area of rain and thunderstorms is expected to develop, fueled by a significant increase in humidity.

What to expect for early next week:

n
• Humidity Peak: Between Monday and Tuesday, dew points could approach 70 degrees, making the air feel heavy and oppressive.
• Temperature Surge: If precipitation stays away, temperatures could soar toward 90 degrees.
• The Silver Lining: If rain develops early on Monday, it may keep temperatures slightly lower and reduce the risk of severe evening storms.

Mid-Week Relief: Cooling Down

The humidity won’t last forever. After some lingering rain on Tuesday morning, a cooling trend will finally arrive. By Wednesday and Thursday, Chicago can expect a return to drier conditions with temperatures dipping back into the comfortable 60s.
