Iowa–Illinois — Bright sunshine spreads across the Mississippi River this morning as warm March air pours into the Quad Cities. Streets in Davenport and Rock Island warm quickly under clear skies, and the day begins with a strong hint of spring.
Temperatures surge to around 76°F today, far above normal for early March. A light southwest breeze moves across the river valley while commuters enjoy dry pavement and clear visibility.
Drivers along Interstate 80, I-74, and US-61 should see smooth travel conditions through the daytime hours. For now, the weather remains quiet and comfortable.
However, meteorologists are closely monitoring a developing severe weather pattern moving toward eastern Iowa and western Illinois.
The warm stretch continues into Tuesday with highs near 72°F, but clouds will begin increasing during the day. Scattered thunderstorms may develop during the afternoon, signaling the start of a more active period.
By Tuesday evening and into the night, storms become more widespread across the Quad Cities region. The National Weather Service indicates an enhanced severe weather risk south of the area, with a slight risk extending across eastern Iowa and northwest Illinois.
Some storms could produce large hail, damaging wind gusts, and isolated tornadoes. Heavy rainfall is also possible, which could lead to localized flooding and reduced visibility for drivers.
Residents should remain weather-aware Tuesday afternoon and evening. Keep mobile alerts active and be ready to move indoors if severe storms approach.
Conditions begin to settle Wednesday, March 11, though scattered rain showers may linger through the day. Temperatures cool sharply behind the storm system.
