It took 10 full days of December to get back to the wintry weather of Thanksgiving week, but it’ll be charging back with a vengeance later today, forecasters say.

As much as 14 inches of snow is forecast by Wednesday evening for some parts of the region, according to a lake-effect snow warning posted Monday afternoon by the National Weather Service.

“It’s mainly because we’ll have more of a westerly wind,” said Aaron Reynolds, National Weather Service meteorologist in Buffalo. “The snow will briefly come through Buffalo and settle into the Southtowns and Southern Erie County.”

The wintry blast is expected from early this evening through late Wednesday for southern Erie, Wyoming, Chautauqua and Cattaraugus counties. Forecasts in those areas call for 3-5 inches tonight and Wednesday with an additional 2-4 inches Wednesday night leading to storm totals of 8-14 inches in the “most persistent lake snows.”

With west winds expected to gust up to 40 mph, blowing and drifting snow could reduce visibility to a quarter-mile, according to the National Weather Service.

Northern Erie County, including the Buffalo metro area and points north and east, along with Genesee County, were placed under a lake-effect snow advisory from late this afternoon to early Wednesday morning. Depending on the direction of the wind, portions of these areas could receive about an inch this afternoon and 2-4 more inches of additional accumulation tonight, according to the forecast.

Overnight temperatures are expected to drop into the teens Wednesday and Thursday. Daytime highs won’t escape the 20s this week.
