June 1st, 2006 Severe Thunderstorms and Flash Flooding

Overview

After being spared for the most part over the last two days of thunderstorms that stayed mainly over the higher-terrain of Central PA, York County saw thunderstorms erupt in the afternoon that repeatedly developed over the same spot in southeastern York County near the towns of Fawn Grove and Brogue. This same area had been hit by torrential rains and flash flooding back in Mid June of 2003!

Reflectivity from 2258z (658pm EDT) with a nearly stationary thunderstorm over extreme southeast York County, PA. This storm produced over 5 inches of rain, and flash flooding in an area that got hit by flash flooding just a few years ago.

KCCX WSR-88D Three Hour Precipitation Estimate from 2000z through 2300z for Southeastern York County. Note the red colors indicating possibly over six inches of rain in three hours! These estimates were deemed to be too high, as they were most likely contaminated by hail, and a KCCX precipitation-algorithm setting that was incorrect. But, this does help to pinpoint the area of greatest rainfall, which is exactly where the flash flooding occurred.
