The National Weather Service says Montana's swollen rivers could begin hitting flood stage Wednesday, one day after severe storms hit the state.

The storms dumped up to 4 inches of rain in some areas and golf ball-sized hailstones on Tuesday.

Meteorologists said a number of funnel clouds were spotted near Billings from a storm system that moved in Monday night. The National Weather Service received several reports of tornadoes.

The rain caused flash flooding around the Musselshell River in central Montana and the Milk River in northeastern Montana. The Musselshell is expected to crest near the central Montana town of Roundup at more than 3 feet above flood stage.

Meteorologist Amy Schnetzler says flash flooding covered the main streets of Glasgow, in northeastern Montana, with 4 to 5 inches of water.
