The mid-Hudson Valley could see its first snowflakes of the season early Friday.
As rain develops on Thursday, a strengthening coastal storm will help pull colder air southward from Canada.
The air temperature around 5,000 feet above the ground will chill below freezing by early Friday, and that could allow for wet flakes to mix with lingering rain, especially in elevated parts of the region.
But temperatures near the surface are expected to hold in the mid-30s, and ground temperatures will probably be even warmer, probably preventing any snow from sticking to pavement.
In mountainous parts of both western Ulster County and Sullivan County, where temperatures are likely to dip closer to freezing, some wet snow accumulation is likely — and a winter weather advisory is in effect for western Ulster. That’s where some delays on Friday morning can’t be ruled out.
Temperatures on Friday are forecast to rise into the low-40s.
I’ll keep an eye on things as they develop. Otherwise, expect a chilly weekend!
