Expect winds gusting as high as 60 mph Sunday night, bringing the possibility of downed trees and power lines, the National Weather Service reported in issueing a high wind warning.
The warning, which affects Cortland County and much of Central New York and the Southern Tier, calls for sustained winds of 20 to 30 mph.
The high temperature will be near 40 Sunday, but dropping to 12 Sunday night, rising to 18 on Monday before falling to 2 degrees Monday night.
With the expected wind, that will bring wind chill factors as low as 6 below zero Sunday night and Monday, and 17 below on Monday night.
Coming with that will be snow -- perhaps 2 inches by Monday night.
Travel will be difficult, particularly for high-profile vehicles, forecasters said. Widespread power outages are expected.
During the worst of the storm, the National Weather Service advises staying away from windows and on the lower level of your home. Avoid travel, too.
