Severe Weather of 13 June 2007
Storms from the Northeast - Day 2

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.

A Storm Damage Survey Team traveled to Southeastern York and Lancaster Counties, but found no strong evidence of tornadic damage.
Most of the damage appeared to be downburst/straight-line wind damage.
