A Severe Thunderstorm Warning remains in effect for Whiteside County until 4pm Monday afternoon.
A cluster of thunderstorms capable of quarter sized hail has been moving through Whiteside County, with several reports of hail across eastern Iowa and northwest Illinois.
The storm is moving to the northeast/east around 45 mph. It may weaken a little as it approaches western Lee County as the environment is a little more stable. However, an approaching cold front will allow for an increase in storm coverage through the evening. Any strong to severe thunderstorm will be capable of producing large hail and damaging winds.
