Powerful weekend storm in store with strong winds, lake effect snow

"We're confident there's going to be a lake effect snow band, the challenge is knowing exactly where it will be."

Buffalo, N.Y. (WBEN) - Here we go. A wintry weekend is in store with powerful winds and eventually significant lake effect snow.

The good news? Friday.

"Today should be relatively quiet during the daylight hours," National Weather Sevice meteorologist Kirk Apfel tells WBEN. It's actually above normal temperatures, a high of 40."

Friday night the rain and gusty winds move in. "The worst of it won't be tonight, but we're still looking at gusts up to 60 mph," Apfel says. "The worst of that will be along the thruway from Buffalo south to the PA state line."

Again, the winds will start out of the southeast, not the prevailing direction for Western New York and potentially problematic for weakened trees.

On Saturday, widespread and stronger winds will overspread the area with gusts up to 65 mph during the day. "The worst will be Saturday, but it's going to continue to be very windy Saturday night, and the winds will last into Sunday."

A High Wind Warning is posted for ALL of WNY late Friday through early Sunday morning. A Lakeshore Flood Warning is also posted for the Lake Erie shoreline in Erie and Chautauqua counties.

The Lake Effect ?

Lake effect snow will begin to develop Saturday afternoon. "Pretty much there's going to be some sort of a band in the general Buffalo metro area, either across it or more off to the south, all the way through the weekend," Apfel says. Pinpointing where the band will be located at any given moment is a challenge, Apfel cautions us. "But wherever that band is, you're going to have extremely difficult, if not impossible, travel conditions once the band gets going."

As for accumulations, there is the potential for a foot or more of snow for areas within the snow band from late Saturday through Sunday evening. "It's going to keep going after that, so some areas could get locally higher than that. The wind will also be a factor, causing blowing, drifting and extremely poor visibility within the snow band.

How confident are forecasters?

"We're confident there's going to be a lake effect snow band, the challenge is knowing exactly where it will be."
