Lake Effect Snow Through Friday for Western New York
Lake effect snow will continue across western New York through midday Friday. Snow may temporarily diminish on Wednesday before low to mid level moisture returns, allowing for potentially higher snow rates Wednesday evening into Thursday. A sharp cutoff between little snow and significant accumulations may take shape. Having said that, an intense lake effect snow band is likely to develop in a southwest to northeast orientation. Snow accumulations of 10-16 inches are expected with locally higher amounts in excess of 18 inches. Hourly snow rates could be several inches with visibilities less than 1/4 mile and wind gusts in excess of 35-40 mph at times.

A Look Ahead
By Friday, a large cold front will be offshore except for across portions of Florida; scattered showers may develop behind the front along the Gulf Coast. A fast moving area of low pressure will bring snow to portions of the Great Lakes; snowfall amounts of 1-2 inches are forecast. Into the weekend, flurries may develop across portions of the Northeast and Ohio Valley on Saturday. Across the Northern Plains and Midwest, there will be the potential for some light snow on Sunday in association with an area of low pressure. As this area of low pressure tracks eastward, snow will be possible across portions of the Great Lakes and Northeast early next week.
