Here's what to expect over the next few days, according to the National Weather Service:
This evening: Lake-effect squalls off Lake Erie to the south of the Buffalo metro area, more lake-effect squalls off Lake Ontario to the north. But for the city itself and the immediate suburbs, it will simply be frigid, with temperatures in the teens. Winds gusting up to 33 mph will make it feel like zero or colder.
Weather radar at 7 p.m. showed bands of squalls sweeping across Niagara and Orleans counties, touching northern sections of Amherst, Clarence and Newstead. Meanwhile, squalls off Lake Erie were hitting North Collins, Springville and Arcade, as well as northeastern Cattaraugus County. Another band was affecting northern Chautauqua County and northwest Cattaraugus County. Snow there was falling at a rate of about an inch per hour.
Later tonight: Two to 4 inches of snow are forecast overnight for Niagara and Orleans counties, where a lake-effect snow advisory is in effect until 7 p.m. Tuesday. Three to 6 inches also are expected in Southern Erie, northern Chautauqua and Cattaraugus counties and Wyoming County, but a full-fledged lake-effect snow warning for these areas is posted only until 7 a.m. Tuesday, a full 24 hours earlier than originally forecast. Heaviest snowfalls are likely in southernmost Erie County and southwestern Wyoming County. Winds will be gusting to 40 mph, creating dangerous whiteout conditions.
Tuesday: Snow showers will produce an inch of snow or less everywhere except Niagara and Orleans counties, where another 2 to 3 inches could fall. It will still be bitterly cold and very windy, with highs only around 20, wind gusts up to 35 mph and wind chills in the single digits or lower.
Tuesday night: Snow showers diminish a bit, but it still will be breezy and chilly, with winds gusting to 30 mph and overnight lows in the low to mid teens.
Wednesday: Cloudy skies and snow showers continue. Temperatures will creep up only as far as the low to mid 20s, but it will feel a lot better. Why? The wind. It's due to calm down considerably.
