» NEW FEATURE ALERT!
I am experimenting with a late evening post focusing solely on the next day’s weather. You can check out what I posted last night for today by clicking here. Be on the lookout for tomorrow’s forecast late tonight.
Tuesday
What: Generally cloudy skies, a late spit of rain
Impacts: None
Some breaks in the clouds this morning will allow for some areas of early sun. However, clouds will eventually win out, with overcast skies for the midday and afternoon hours.
After 4 PM, there may be a few stray spits of rain, persisting until around 9 PM. Most areas will probably not see enough rain to totally wet the pavement.
Temperatures will push into the upper 30s and low 40s late this afternoon, then hold mainly steady through the evening and much of the overnight. South and southwest winds will build late this afternoon and tonight with some localized gusts as high as 35 mph.
Wednesday Daytime
What: Cloudy with gradually increasing showers
Impacts: Minor
Low pressure will move into eastern Canada, leaving a poorly defined frontal boundary over the area. This will serve as a focal point for clouds, drizzle, and gradually increasing showers during the afternoon.
None of the rain is expected to be heavy, but it should become more frequent and steadier as we approach sunset.
Temperatures will not move much, sticking to the upper 30s and low 40s with light south and southwest winds.
Wednesday Evening, Overnight
What: Widespread snow
Impacts: Moderate
A new area of low pressure will develop to our southeast late Wednesday, pulling in colder air and increasing precipitation. Rain will turn to steady snow, which should last through the evening and into the overnight hours.
There may be a band of heavier snow early on during the transition as the cold air first starts to move in.
Snow accumulations will generally be on the order of 2-4 inches. Some areas west of Keuka Lake may see a bit less, while some higher elevations in the eastern half of the region may see up to 6 inches. Also, some enhancement off Lake Ontario may lead to slightly higher amounts in Wayne, northern Cayuga, and Onondaga counties.
Temperatures will fall rather quickly, from the mid 30s at 7 PM to the mid 20s by midnight. This may enhance the chances for icy, slick roads in addition to the falling snow.
Winds will increase overnight as the snow tapers off, coming from the northwest with gusts to 30 mph. Temperatures will reach the mid 10s by dawn.

Thursday
What: Cold, scattered lake effect snow
Where: Lake snows most likely in the northeastern quadrant of the region.
Impacts: Slight
Temperatures will hold steady in the mid 10s throughout Thursday. With wind gusts of 30-35 mph, the wind chill will be closer to 0 degrees. Localized blowing snow will also be likely.
Lake effect will transition to a spray of snow showers over the northeastern Finger Lakes. This includes most of Wayne, Onondaga, Cayuga, and Cortland counties, as well as northern parts of Seneca and Tompkins counties.
Daytime snow accumulations across these areas will be 1-3 inches.
Friday
What: A little sun, a few flurries
Impacts: None-Minor
Winds will swing around to the south early Friday, ending the lake effect and bringing in a window for some sunshine. The window will be brief, with clouds increasing ahead of a weak low pressure system moving through the Upper Great Lakes.
This system may bring some snow showers in the afternoon and evening hours. At this time, the snow looks minimal with little to no accumulation.
Temperatures Friday will start in the low 10s and rise to the mid 20s. The south wind will get a bit blustery in the afternoon with some gusts over 30 mph.
Weekend and Beyond
Temperatures will get a slight boost on Saturday, possibly reaching the mid 30s for a time before colder air marches right back in. Highs will struggle into the low 20s Sunday and Monday, and may get even colder next week.
No major weather systems are expected during this time, but small, quick moving systems will bring occasional snow showers. Areas of lake effect snow showers will also be likely. While snow will be around almost daily, accumulations will generally be minimal.
This deep winter cold seems likely to stick around for the remainder of January and into February. Colder than average temperatures are favored on the models beyond that as well.
