Nuisance Snow Tuesday
Small storm systems continue to move through the Finger Lakes in rapid succession.
Last night, one system clipped the southern parts of the Finger Lakes while this morning a new system is moving in from the west.
Snow will fall throughout the day today as this system moves through. The snow that falls should have little impact on travel.
Roads will remain mostly wet with temperatures climbing above freezing if not there already. High temperatures will reach the mid 30s with a few upper 30s possible.
The snow will not accumulate much with just a fresh thin coating. Some of the snow could mix with or turn to rain in typically warmer locations.
Most areas will see the snow stop by this evening’s commute. A few lake effect flurries will linger along and northeast of an eastern Wayne county to northern Cortland county line. The lake effect will not organize much until it lifts out of the Finger Lakes.
The overnight looks quiet with lows dropping back into the low 20s. Some additional snow may develop off Lake Erie for areas between Buffalo and Rochester towards dawn as southwest winds develop.
Tricky Travel on Wednesday
An arctic cold front will blast through the Finger Lakes on Wednesday with strong winds, snow squalls, and bitter cold air set to flood in.
Snow showers from Lake Erie will cross the region during the morning hours as winds turn towards the west. A few heavier bursts may be possible, especially for areas along and west of I-390.
I then expect heavier squalls as the front moves in during the midday and afternoon hours. These squalls will be the type that results in rapid changes in visibility and travel conditions.
Brief white out conditions will be possible, especially considering winds will gust over 30 mph. A fast inch of snow will accumulate, making roads slick. A flash of lightning or two may even be possible.
Multiple heavy squalls will be possible throughout the afternoon. They will make travel difficult. If you have travel plans in Upstate New York on Wednesday afternoon, be ready for these rapidly changing conditions. Use headlights, slow down, and pull off the road into a parking lot or other safe location if necessary.
Squalls will lessen during the late afternoon only to be replaced with some lake effect squalls both from Lake Ontario and the Georgian Bay off Lake Huron. These will be most likely between 6pm and midnight anywhere in the Finger Lakes.
Deep Winter Cold
By Thanksgiving morning, the snow should have tapered to just a few flurries south of Lake Ontario. Winds look favorable for some enhancement off Cayuga Lake, though, so locally heavier snow will be possible through Thursday morning in and around Ithaca.
Morning lows Thursday will be in the low and mid teens where lake effect lingers with single digits across the Southern Tier. Wind chills will range from near 0 to -10 degrees.
Sunshine will be likely on Thursday outside of any lingering lake effect clouds. Winds will gradually lessen over the course of the day. However, with high temperatures struggling to even get to 20 degrees, wind chills will remain in the single digits or lower.
Early morning Black Friday shopping will turn bitterly cold after a night of mostly clear skies.
As is typical in these scenarios, a wide range of temperatures will develop across the Finger Lakes. Morning lows right along the shores of both the Finger Lakes and Lake Ontario will range from +5 to +10 degrees. Most of the region will end up a few degrees on either side of 0 degrees. Temperatures could drop as low as -10 to -15 degrees in some valley locations of the Southern Tier.
A south wind will increase on Friday and sunshine will be abundant. This will help temperatures rebound with most areas in the upper 20s.
Low and mid 40s are likely this weekend as a moderate strength storm system rolls in. Precipitation from this event looks to be just rain.
