(Wednesday, December 16th, 2020) Get your shovels/snowblowers ready because a significant snowfall is likely between late Wednesday afternoon and mid-morning Thursday.
Quiet with clouds increasing quickly Wednesday.
Snow should overspread the region between about 2 and 6 pm.
Roads will start getting slick around the evening ride home for many as the snow will stick pretty quickly. Highs will be in the mid 20s.
Newest data is suggesting a slight shift to the north with this developing storm.
This means a very significant snowfall for us here in the Southern Tier of NY and Northern Tier of PA!
The nor’easter will develop near the Mid-Atlantic Coast late Wednesday/early Wednesday night and then move northeast off the New England Coast late Wednesday night/Thursday.
Snow will become moderate to heavy here in the Southern Tier after 8 or 9 Wednesday evening and fall at 2 to 3” per hour at times during the overnight!
Snow should taper off quickly after 8 or 9 Thursday morning as the storm pulls away from the New England coastline.
Travel will be very difficult late Wednesday night through the Thursday morning commute.
Snow accumulations will range from about 12 to 20” with locally higher amounts when all is said and done by late Thursday morning!
A Winter Storm Warning has been issued for all of the Southern Tier as the confidence for high impact/very significant snowfall is very high. It would take a significant shift in the storm track to make this storm a low impact system for us, which we don’t see happening at this point.
The weather will be chilly, but quiet to end the week with highs in the 20s to low 30s as high pressure builds back in.
