Here we go again.

Chautauqua County and a large portion of Western New York is under a lake-effect snow warning as a clipper system — a fast-moving low pressure weather system — is expected to bring widespread snowfall across the state through 4 p.m. Saturday.

Windy conditions will develop Thursday with gusts between 30 and 45 miles per hour and have the potential to down limbs and cause power outages while impacting visibility. The coldest air of the season is expected on Friday to combine with winds resulting in feels-like temperatures in the single digits to mid-20s during the day, with single digits to below zero Friday night. Travelers should be prepared for rapid changes in weather, visibility and road conditions.

“As some New Yorkers recover from the first major lake effect snowstorm of the season, we will experience more winter weather bringing snow, winds and cold to a larger area starting tomorrow,” state Gov. Kathy Hochul said. “New York State agencies are prepared to respond and will closely coordinate with our local partners across the State — I urge all New Yorkers to monitor their local forecasts and exercise caution.”

The greatest amounts of snow are expected across the higher terrain of Chautauqua and western Cattaraugus Counties. The National Weather Service is expecting total snow accumulations of 10 to 20 inches in the most persistent lake snows. Winds gusting as high as 50 mph will produce considerable blowing and drifting snow.

Areas across the region are already under considerable snowfall. Amounts through early this week included: Cassadaga, 56.5 inches; Dewittville, 49; Mayville, 44; Fredonia, 37.1; Dunkirk, 32.1; Silver Creek, 25.1; Kennedy, 22; Falconer, 19.7; and Bemus Point 18.5.

This new storm will again make travel very difficult. Areas of blowing snow will significantly reduce visibility. The hazardous conditions will impact the morning and evening commutes on Thursday. Gusty winds will down tree branches and cause isolated power outages.

The Thruway Authority is monitoring the forecast and ready to respond with 689 operators and supervisors available. During last week’s storm, portions of Interstate 90 were closed in both New York and Pennsylvania due to poor visibility and road conditions.
