Severe Weather Hazards: The primary threats include damaging winds, large hail, and the potential for tornadoes, particularly during evening storm rounds on Thursday. Heavy rain and possible flash flooding are also concerns.
Extreme Heat & Humidity: Thursday will see highs in the 80s, but extreme humidity will push heat index values to a dangerous 90 to 100+ degrees, posing a risk of heat-related illnesses.
Multi-Day Event: The severe weather pattern began Wednesday evening and is expected to continue with multiple rounds of storms through Thursday.
Why this matters: This combination of severe weather and extreme heat creates hazardous conditions for residents, impacting outdoor activities, travel, and personal safety. Staying informed and prepared is crucial to mitigate risks.
The current weather system affecting the Quad Cities is characterized by a persistent flow of warm, moist air creating an unstable atmosphere conducive to storm development. A First Alert Day has been issued through Thursday due to the high likelihood of impactful weather. After an initial round of strong storms on Wednesday evening, Thursday will see morning, afternoon, and evening storm rounds. The most significant threat of tornadoes is anticipated with the evening rounds, as a front moves through the region. This front is expected to trigger the final, most intense storms of the period.

Seek Shelter: In case of severe thunderstorm or tornado warnings, have a plan to move to a sturdy indoor shelter, ideally a basement or an interior room away from windows.
Prepare for Power Outages: Charge electronic devices, have flashlights and extra batteries ready, and ensure you have a way to receive emergency alerts.
Stay Cool: During periods of extreme heat, limit outdoor activities, stay hydrated by drinking plenty of water, and seek air-conditioned environments. Never leave children or pets unattended in vehicles.
Secure Outdoor Items: High winds can turn loose objects into projectiles, so secure anything that could be blown away.
