Damaging Winds and Torrential Rains
September 18th, 2012

A complex and powerful low pressure system moved across the region on Tuesday, September 18th bringing damaging winds and widespread heavy rainfall. A low pressure system originating in the deep south approached the region from the southwest during the day as a strong cold front approached from the Great Lakes region. These systems merged and moved across the northeastern United States. Moisture was transported into the region on a very strong low level jet. Rainfall totals ranged from just over an inch up to around 7 inches with the highest amounts in the eastern Catskills. Despite instability being very limited, the winds field was so strong that showers and low-topped thunderstorms were able to transport stronger (damaging) winds to the surface.
