Jet Stream Brings Two Very Different Junes to the Western & Eastern U.S. | NOAA Climate.gov | Chris' Regional Geography | Scoop.it

"During June, the jet stream developed kinks in its air current that served to shuttle moisture-packed frontal systems and their associated thunderstorms toward the East Coast while leaving the West high and dry.  These kinks are called troughs and ridges. A ridge is a large area of above normal atmospheric pressure that pushes the jet stream northward of its usual position.  A trough is a low-pressure area that allows the jet stream to dip southward.  Since early June, the eastern half of the U.S. has been sandwiched between two ridges: one over the West and the other over the western Atlantic, creating a trough in between. "
