Overview

Showers and thunderstorms rolled across Central PA during the afternoon and evening of Tuesday May 27th, as a cold front moved through from north to south. The storms were generally weak, but one storm managed to make some wind damage in Lebanon County. See the radar picture around the time of the tree damage report below.

If no more severe weather occurs before the end of the day this Saturday (5/31), this will be the only severe storm in Central PA during all of the month of May 2008. It is very unusual to have just one severe event in any May.
