Davenport, IA – A widespread freeze is expected across eastern Iowa and northwest Illinois tonight, with temperatures dropping into the mid-to-upper 20s in some areas and low 30s further south, posing a risk to sensitive vegetation.
According to the US National Weather Service Quad Cities office, a Freeze Warning and Frost Advisory are in effect for parts of the region overnight into early morning hours Sunday. The alert covers much of eastern Iowa, including cities like Cedar Rapids and Iowa City, as well as western Illinois communities such as Moline and Rock Island.
Forecasters say overnight lows could reach around 28 degrees in northern areas, including Dubuque and Freeport, while the Quad Cities region is expected to hover near 30 degrees. Southern zones may stay slightly warmer, around 32 degrees, but still cold enough for frost formation.
The cold snap is expected to impact gardeners and agricultural interests the most, especially those with early spring plantings. Officials warn that unprotected plants could be damaged or killed by the freezing temperatures.
Residents are advised to cover or bring inside sensitive vegetation and disconnect garden hoses to prevent freezing. Sprinkler systems should also be turned off overnight.
This marks one of the colder nights this April for the region, following a stretch of milder spring weather. Temperatures are expected to rebound after sunrise Sunday.
