CHAMBERSBURG, Pa. - The Tri-State area weathered some severe storms during June, and the month may go out with yet more thunderstorms, according to the National Weather Service.
Weather Service Meteorologist Rick Winther said Monday the region can expect showers and thunderstorms today as a cold front pushes through the area from the Ohio Valley. Some of those thunderstorms could be severe, he said.
"Just normal, active summertime weather," Winther said.
"You have a very active jet stream just north of the area," Winther said of the band of fast-moving winds in the stratosphere that can affect the weather. He said that "normally migrates into Canada at this time of year."
The jet stream can prevent warm, humid air from moving farther north, allowing a relatively weak disturbance to bring on stormy weather, Winther said.
