Overview
A widespread rainfall of 1.5 to 3.5 inches occurred over a 24 hour period between Sunday afternoon (24 Jan 2010) and Monday afternoon (25 Jan 2010). A powerful storm moved north through the Great Lakes, and brought very warm air up into Pennsylvania for the 4th weekend in January of 2010. High temperatures on the 24th and 25th were in the mid 40s to near 60 degrees. The rainfall was generally an inch to an inch and a half over the western mountains, to nearly 4 inches in the higher elevations to the east of State College. Places to the southeast of a York to Reading line received less than an inch from the entire storm. The extremely heavy rain caused small creeks and streams to flood very quickly, and even the larger rivers rose over flood stages or very close to flood levels.
