A routine winter day is forecast Tuesday ahead of a brewing winter storm Wednesday.
That storm, which will skirt past Western New York to the south, could dump a half-foot of snow or more snow across parts of the region over a roughly 18 hour period, with more snowfall farther to the east, National Weather Service forecasters said.
Here's what to expect:
Today and Tonight
Chances for snow showers or flurries this morning in the metro Buffalo area.
Forecasters at the weather service said to expect snow to gradually diminish through the mid-morning.
Otherwise, it'll be mostly cloudy with a daytime high temperature in the mid 20s, forecasters said.
Chances for snow pick up overnight and becoming more likely by dawn Wednesday. Overnight temperatures will be in the mid teens, the weather service said.
An all-day snow throughout the region is expected.
Chances for snow are 100 percent.
Forecasters project that the heaviest snow will fall farther to the east.
For that reason, a winter storm warning was issued for Wyoming, Cattaraugus and Allegany counties.
The rest of Western New York's counties are under a winter weather advisory from 4 a.m. Wednesday to 4 a.m. Thursday.
In the Buffalo metro area, more than 6 inches is possible between about 7 a.m. and 7 p.m., forecasters said.
There's an outside chance it could chase down Buffalo's snowiest day this winter, Jan. 17, when 6.3 inches of snow fell.
Heading into Tuesday, 69.8 inches of snow has fallen at the Buffalo Niagara International Airport. That's about 4.8 inches more than normal by this date in the season.
So far this winter, there's been 40 days of measurable snowfall of more than one-tenth inch. That's about 2 days more than average.
The last winter there were as many measurable days of snow was in 2013-14 when there were 46 such days, weather service data shows.
Although lesser amounts of snow are expected in Western New York, forecasters project up to a foot is possible in those areas under the winter storm watch, south and east of metro Buffalo.
Snow should start tapering off by mid-evening in the metro Buffalo area and scattered snow showers are likely in the late evening.
Overnight lows are forecast to return to the teens.
Chances for snow showers are in the forecast Thursday and Thursday night as well with highs in the mid 20s and lows in the low teens.
Snow becomes likely again on Friday, forecasters said.
