Pre-Halloween Snowfall and Heavy Rain Event
Associated with Tropical Moisture from Hurricane Wilma
IR Picture

An early season (pre-Halloween) Snow event occurred on October 24th and 25th giving Central Pennsylvania its first taste of winter. The event started out as as rain when moisture associated with the remnants of Hurricane Wilma and Tropical Storm Alpha streamed up along the East Coast. This tropical moisture was also tapped by a developing East Coast low pressure center that developed in response to an upper level disturbance moving over the region. As colder air moved into Pennsylvania behind the low on Oct 25th much of the rain mixed with and changed to wet snow across Northern and Central Pennsylvania, especially at higher elevations above 1500 feet.
