A strong cold front swept across east central New York Wednesday, December 1st,  bringing strong and gusty winds and heavy rains to the area. With the passage of the cold front, winds quickly shifted from the south-southeast to the west, and temperatures rapidly dropped from the 50s into the 30s. Rain mixed with and changed to sleet across the Mohawk Valley in the wake of the cold front, resulting in some minor traffic accidents.
Ahead of the cold front, a very strong south to southeast low level jet resulted in wind gusts up to 55 mph, and with the passage of the front there were wind gusts up to around 50 mph. These strong wind gusts downed trees and power lines, resulting in power outages.
Generally, 1 to 3 inches of rain fell across the area with higher amounts of 5 to 7 inches across the higher terrain of the eastern Catskills. Moderate to major flooding was reported in western Ulster and Greene Counties. River flooding occurred in the eastern Catskills, southern Adirondacks and Mohawk Valley. In addition, urban and small stream flooding also occurred across the local area.
According to the Albany International Airport, three planes, including one international flight on route from Newfoundland to Newark Liberty International Airport, were forced to land at the Albany International Airport due to the extreme weather conditions along the East Coast.
