OKLAHOMA CITY -- Thunderstorms have brought lightning and heavy rain to parts of Oklahoma, causing minor flooding.

National Weather Service meteorologist Bruce Thoren says the storms developed early Monday in west-central and central Oklahoma. Another cluster of storms passed through southeastern parts of Oklahoma.

An Oklahoma Mesonet site in southeastern Oklahoma County has measured 2.56 inches of rain since midnight. The weather service issued a flood advisory for parts of Oklahoma, Cleveland, Pottawatomie, Pontotoc and Seminole counties. Authorities shut down a portion of Interstate 235 in Oklahoma City for a time Monday because of the heavy rain.

Thoren says winds of around 55 mph were measured near Spencer overnight as one storm passed through the area.

He says there are reports of tree damage around Stillwater.

The storms moved out of the state in time for a warm Memorial Day afternoon.
