National Weather Service Meteorologist David Zaff tells WBFO News the worst of the storm will happen during the daylight hours, with one to two inches of accumulation falling per hour in the city of Buffalo.
"We are looking for the highest snow accumulations over the north towns and along the Lake Ontario shoreline, with the least accumulations from Buffalo south towns," said Zaff.
Heavy snows will cover roads and make travel difficult in some areas. Expect the worst conditions from mid-morning Friday to early evening when snowfall rates may exceed an inch per hour. It is during this time that the bulk of the snow will fall.
Visibilities on the roads will be down to a half-mile or less.
The heaviest snow will fall during the day on Friday. The storm will cause heavy snow conditions mixed with sleet at times on roadways.
The storm warning for Southern Erie, Wyoming, Chautauqua, Cattaraugus and Allegany counties has been canceled. That includes Orchard Park, Springville and the cities of Jamestown and Olean.
The National Weather Service has issued a winter weather advisory until 5 a.m. Saturday for those counties. 4 to 6 inches of accumulation is expected Friday afternoon. Visibilities could be down to a half-mile at times.
Those counties will also experience hazardous driving conditions.
"North to south you will have a variety of weather. Take it slow, maintain a safe distance and use your winter driving skills," said Zaff.
A massive winter snow storm is also hitting the Northeast Friday. Forecasters are predicting it could be a historic blizzard. The storm is expected to dump 3 feet of snow from New York City to Boston and into other New England states.
"The real story is New York City and the Boston area," said Zaff.
More than 3,000 flights have been canceled in some cities. If you have air travel plans its best to check with the individual airline for cancelations and delays. You can go to the Buffalo Niagara International Website for information on flights.
