You can stop dreaming about a white Christmas: Snow Saturday and Sunday will guarantee a White Christmas across Western New York, and it will stay around for a while, too.
But the latest weather advisory cautions about blowing snow and slippery road surfaces.
After seeing 2 to 4 inches of wet snow throughout the area earlier today, snow and blowing snow is part of the National Weather Service's updated winter weather advisory issued Saturday evening through 10 a.m. Monday for Niagara Falls, Medina, Rochester, Newark, Buffalo and northern Erie County, Batavia, Geneseo and Canandaigua areas.
Slippery road conditions are in the mix for Christmas Eve night with poor visibility and snow accumulations of 3 to 6 inches forecast.
Winds gusting as high as 35 mph will cause blowing and drifting snow in some areas, the weather service said.
Most of the region will have a break in the snow overnight into the first half of Sunday, with a low overnight around 25. A light snow will fall overnight Sunday into Christmas Day, said National Weather Service meteorologist Aaron Reynolds. Sunday's high will be 31, but the light snow will be widespread Sunday night.
"As you wake up in the morning, there should be a couple inches of snow on the ground," Reynolds said of Monday, and he added, "On Christmas Day, the lake-effect should get going south of the city."
Southern Erie County, Cattaraugus and Chautauqua counties should get the brunt of that storm, he said. Winds will be gusting to 30 to 35 mph.
The high on Christmas Day will be in the low to mid-20s, then the temperature plunges, with highs in the teens the rest of the week, he said.
