Rochester, N.Y. (WHAM) - A Winter Storm Warning is in effect for all of Western New York from Saturday afternoon through Sunday Afternoon.
This will be a significant winter storm in the Rochester area. The area of low pressure is already developing over the Great Plains, and will gradually move in our direction between now and Saturday, when it will arrive.
Steady snow will develop during the late morning on Saturday. The intensity of the snow will pick up through the afternoon and early evening. The heaviest of the snow will likely occur Saturday night into Sunday. Travel will become dangerous during the night. By Sunday morning, many areas near Rochester will see between 10 to 15 inches of snow. Totals will likely be on the lower end of the range southwest of Rochester, and on the upper end of the range to the east. The potential will remain for at least some more lake effect snow to follow on Sunday for some towns, especially north of the Thruway. These areas could see another 3 to 6 inches of snow from lake effect.
Blowing and drifting snow will both be problems, especially Saturday night and into Sunday, and possibly beyond. Given the very cold temperatures which will be in place, this will be a very light snow, but plenty of it. With the wind gusting up to 30 miles per hour during that time period, expect the snow to easily blow and drift. Travel will be a problem in open areas because of this.
As the wind picks up, low wind chill will be a problem. The wind chill value will likely drop below zero late Saturday night, and will remain below zero through Monday night. At its lowest, the wind chill will drop as low as the double-digits below zero.
Through Sunday and into Monday, lake effect snow will develop off Lake Ontario, causing the snow to continue for at least some areas.
