A light snowfall is expected in the Finger Lakes on Sunday as a broad area of disturbed weather triggers the development of a weak low along the Mid-Atlantic coast.
Snow showers will begin to move in from the southwest during the second half of Sunday morning. A few pockets of freezing rain may mix with the snow, and areas along and north of I-90 could see some regular rain as well.
The snow will be spotty and light into the early afternoon. The low will begin to develop by the mid-afternoon, leading to an increase in coverage and intensity of the snow. Pockets of moderate snow will be possible within the larger area of light snow.
The steady snow will only last for a few hours and should pull east by the early evening. Flurries will linger, but with little to no additional impact.
Most of the Finger Lakes should see around an inch of accumulation. Some areas along and north of I-90 may not even reach that threshold if rain does mix in. The best chance for over an inch will be in the higher elevations through the Southern Tier and into Central New York.
Higher snow amounts over two inches should stay southeast of the region, closer to the center of the small low pressure.
Travel conditions should not be impacted much by the snow. Temperatures should stay near or slightly above freezing, even as the sun sets, and the snow rates will never become too burdensome. Still, as usual, untreated, lesser-traveled roads, especially in higher elevations, may get a bit slick.
A few light rain or snow showers will be possible into Monday, but with few impacts. Check back Monday morning for a full look at the weather over the week ahead.
Happy New Year, Drew!
