Chicago, IL – Residents north of Interstate 80 should prepare for potentially severe thunderstorms beginning early Thursday morning, with storms expected to impact the region between 1 and 7 a.m.
According to the National Weather Service in Chicago, the highest storm coverage is likely along and north of the I-80 corridor. Forecasters say all storms in the area may produce lightning strikes and intense downpours, potentially slowing early morning commutes.
The strongest storms may bring damaging wind gusts capable of toppling tree branches or unsecured outdoor items. Damaging hail is also possible and may dent vehicles or cause minor structural damage. Storms are expected to move eastward at speeds up to 50 mph, increasing the need for overnight alertness.
Officials urge residents to have multiple ways to receive emergency warnings, including at least one method that can wake them overnight. Emergency weather radios and smartphone alerts are recommended.
While the severe weather threat level remains low (Level 1 of 5), the timing and nature of overnight storms increase the risk for surprise disruptions. Those living or traveling north of I-80—including in parts of Cook, Lake, and Will counties—should remain weather-aware through early Thursday.
