The National Weather Service has issued a tornado watch for York and Cumberland counties and southern New Hampshire until 8 tonight.

Currently, a warm front is near the Massachusetts and Connecticut border and is expected to move north into southern New Hampshire and southwestern Maine this afternoon. Chris Kimble, a forecaster with the weather service in Gray, said there will be enough instability and wind sheer in the atmosphere to support rotating thunderstorms. He said the formation of a tornado would depend on how far north the warm front moves.

“We are expecting the best tornaado potential to be along and into the south of the warm front,” Kimble said. “If tornados form, it can do a significant amount of damage if it hits any structures.”

A tornado watch was issued Saturday, but Kimble said there were no confirmed reports of a tornado.
“There was damage, but we are not sure if it was a tornado or strong winds,” he said.
