Davenport, Iowa – Gardeners across northern Illinois and northeastern Iowa should prepare for a chilly night, as patchy frost could threaten outdoor plants with temperatures dipping to the mid-30s by early Friday.
According to the National Weather Service Quad Cities office, overnight lows are expected to drop between 34°F and 42°F, especially in rural and low-lying areas from northern Illinois into northeastern Iowa. A light frost may form in places like Freeport, Galena, and Decorah, posing a short-term risk to sensitive vegetation.
Daytime conditions remain pleasant across the region, with mostly sunny skies and highs ranging from the mid-60s Thursday to the low 80s by Sunday. Breezy conditions may develop, especially Friday afternoon. Cities like Moline, Rock Island, and Cedar Rapids will see progressively warmer days, with Saturday and Sunday reaching highs near 83°F.
Residents with gardens or potted plants are urged to cover vegetation or bring them indoors overnight. This brief cold snap marks a seasonal transition before a warmer pattern dominates the weekend.
The frost risk diminishes after tonight, but updates will follow if temperatures dip again. Keep an eye on local NWS alerts as growing season risks remain through mid-May.
