A stretch of dangerous cold starts the week across the Finger Lakes, followed by a slow warmup and several chances for snow as multiple systems move through the region.
Bitter cold this morning
Today begins with some of the coldest conditions of the winter so far. A Cold Weather Advisory remains in effect through 10 a.m. for Cayuga, Seneca, Ontario, Wayne, Livingston, Yates, and surrounding counties.
Wind chills will dip as low as 20 below zero in parts of the Finger Lakes. The National Weather Service warns frostbite can develop on exposed skin in as little as 30 minutes. Officials urge residents to limit time outdoors, dress in layers, and keep pets inside during the morning hours.
Gradual improvement later today
Conditions slowly improve as the day goes on. High pressure over the eastern Great Lakes allows temperatures to recover into the 20s by afternoon. While that’s still cold, it marks a noticeable improvement from the morning wind chills.
Skies stay mostly quiet through Monday night, with no significant precipitation expected.
Winter system arrives Tuesday
Attention turns to Tuesday as a winter weather system moves across western and central New York. Forecasters expect light snow to develop across much of the Finger Lakes during the morning.
As slightly warmer air moves in south of Lake Ontario, some areas in Cayuga, Seneca, Ontario, Yates, and Livingston counties could briefly see a mix of snow, sleet, freezing rain, or rain before colder air returns later in the day. Meteorologists note uncertainty remains on how much moisture this system produces and how long any mixed precipitation lasts.
Areas farther north and east are more likely to stay all snow.
Snow chances increase midweek
Colder air pushes back into the region Tuesday night, setting the stage for lake-enhanced and lake-effect snow. From Tuesday night through at least Thursday night, periods of snow are possible across the Finger Lakes.
The National Weather Service says snowfall could come in waves, with the best chance for more persistent snow southeast of Lake Ontario. While temperatures aloft won’t be as cold as earlier this winter, enough contrast between the cold air and lake waters exists to support accumulating snow at times.
Exact totals remain uncertain, but forecasters say a few inches could fall during any six-hour period under stronger snow bands.
Travel impacts possible through Thursday
With snow showers expected on and off through midweek, travel conditions may change quickly, especially during lake-effect bursts. Drivers should plan for reduced visibility and slippery roads at times.
Temperatures remain seasonably cold through the rest of the week, keeping any snow that falls firmly in place.
