The area-wide snow has ended, but lake flakes will continue to fly tonight, delivering several more inches of snow through Monday morning. In addition to this, the winds will be gusty out of the northwest, creating brief whiteouts and reduced visibility tonight and Monday, due to the light nature of the snow.
By the time the snow shuts down, most spots will have picked up anywhere from 1-2 feet of snow, heaviest north thanks to Lake Ontario.
The next big threat after difficult travel conditions because of snow will be the cold. This will be the focus for the next 48 hours as wind chills are already running well below zero to start Sunday and will remain in the negatives through Monday afternoon. Arctic air will move across Western New York and will mark some of the coldest air of the season. Wind chill warnings are posted for Livingston, Ontario, and Wyoming Counties through Monday afternoon with Wind chill advisories for Monroe, Wayne, Orleans, and Genesee Counties. Frostbite can occur very quickly with these bitter cold temperatures and it is very important to protect yourself with this type of cold blast. The air over New York will be some of the coldest in the entire Continental United States.
