A few snow showers from a weak disturbance will drift through the Finger Lakes on Monday.
This disturbance is caught in the northerly flow behind a nor’easter just clipping the coast of New England with heavy snow.
High temperatures on Monday will be in the upper 30s, but the precipitation that falls today should be mostly snow.
Snow showers will clear out tonight, leaving partly cloudy skies and lows in the 20s. Tuesday will be warmer, with highs into the upper 40s with increasing clouds. A few showers may start to move in late in the day, but most areas will stay dry while the sun is still in the sky.
A weather system will pass by Tuesday night into early Wednesday with some rain showers. This will leave a frontal boundary behind, which will create some interesting weather for the second half of the week.
A sharp temperature gradient will likely set up, with warm air across the Southern Tier and cold air closer to Lake Ontario. Any wobbles in the frontal position could have drastic impacts on the temperatures across the Finger Lakes.
At this time, it looks warmest Wednesday and Thursday night. Wednesday night and Thursday, however, may get cold enough for more snow to fall, mostly along and north of I-90. Several inches may even fall.
A new system will move in with rain showers Thursday night into Friday. This system will remove the front from the region, resulting in a quiet weekend.
