On and Off Snow

A spray of snow showers off of Lake Erie will stick around the Finger Lakes region through the day and nighttime hours.

West-southwest winds will remain well aligned over Lake Erie for snow showers to continue through the Finger Lakes. The snow will be on and off, and much of what falls will be light. The best chance for some squally conditions will be west of I-390.

Accumulations during the daytime hours today will range from nothing to an inch or so.

The wind will be steady at 10-15 mph with gusts as high as 25-35 mph. The strongest gusts should be north and west of Penn Yan for places like Rochester, Geneseo, and Canandaigua. A few gusts over 35 mph will be possible in those areas.

Temperatures will mostly be in the low 30s today with upper 20s in higher elevations. A few places along and north of I-90 could end up in the mid 30s, though.

As the sun sets tonight, the snow should increase in coverage and accumulate easier. Localized amounts of two or three inches will be possible, especially in the hills south of Syracuse and for areas west of Penn Yan.

Toward dawn Wednesday, winds will turn to the northwest. Lake Erie snows will move south and will be replaced by Lake Ontario snows. A few heavier bursts may be possible across the northern half of the region during the morning commute with a quick additional inch or so.

Morning lows will range from the mid 20s into the upper teens, with the coldest air over higher elevations.

The snow will wind down Wednesday morning with just a few flurries lingering into the afternoon. Some breaks of sun may even be possible.

It will remain cold though, with few, if any, areas reaching 25 degrees tomorrow. Higher elevations may struggle to even reach 20.

More Snow Showers

Quiet weather will last from Wednesday afternoon, through the night, and into early Thursday.

Winds will turn to the south ahead of a small weather system, which should bring temperatures back to near or above 20 by Thursday morning after dropping into the teens or even single digits Wednesday evening.

Light snow will overspread the area Thursday morning as the system swings through. Northern areas are more likely to see steady snow than southern areas, but accumulations should stay around or under an inch.

Lake effect snow showers will set up on west and then northwest winds behind the system.

Snows Thursday night and early Friday will focus due east of the Great Lakes but will swing south during the day. A spray of snow showers off Lake Ontario will continue into Friday night and Saturday. Generally light accumulations are expected in the Finger Lakes, but favored snow belts could see a few inches.

Temperatures will get a jump into the mid 30s on Thursday with low 30s on Friday. Cold air will move back in for Saturday with highs around 20 degrees. Sunday will be no warmer, but skies should turn sunny as high pressure builds in overhead.

If skies stay clear, Monday morning could end up quite cold. However, clouds will be moving toward the region as the next weather system approaches. There remains too much uncertainty with this system to know its details at this time.

The general pattern of chilly temperatures and lake effect snow showers should continue behind that system, through the end of January, and into early February.
