| Early (Earliest) Snow - October 15-16, 2009 |
A very heavy and wet snow fell across Central Pennsylvania during the daytime on Thursday the 15th and all night into Friday the 16th of October, 2009.
This storm was noteworthy for two reasons:
1) This storm made the earliest measurable snow of any winter season on record in many places.
2) This storm produced a large amount of damage to trees (which also downed power and telephone lines) across much of the northern mountains and even down into State College.
An upper trough digging southward into the eastern U.S. from the Great Lakes helped to enhance a surface low forming over the Gulf Coast States - eventually spinning the storm up off the the North Carolina coast. The storm center then traveled toward Cape Cod and pulled a great amount of moisture into the mountains from the ocean.
Enough cold air was in place for the moisture to fall as snow over the central and northern mountains, but mainly rain in the southern third to half of the state.
