A powerful storm system will continue to bring heavy mountain snow, rain, and high winds to the Pacific Northwest and northern California through midweek. Heavy rain and flash flooding potential exists across the central Gulf Coast over the next few days, including the Florida Panhandle. A Slight Risk (level 2 of 4) of excessive rainfall is in effect Tuesday. Read More >
Overview
As with the day before (June 12th), a number of thunderstorms fired up in the afternoon heating over Central and Northern PA. These storms then moved south and southwestward into South-Central PA - arriving rom the northeast. This storm movement was very unusual (and the second day in a row like this) - as our predominant/usual flow pattern over Central PA makes most storms move in from the west or south or even sometimes northwest. But, northeast to southwest moving thunderstorms are rare in Central PA.
