"A clipper system brought 2 to 6" of wet snow for most of central NY late Monday night into this morning.
NWS forecasters issued a winter weather advisory for those three counties from 4 a.m. through 9 p.m. Wednesday.
We will have to deal with an Arctic air mass (temperatures in the teens and low 20s), gusty winds, some accumulating lake snow and blowing and drifting tonight through Wednesday.
The big story will be heavy lake effect snow on the backside of this clipper. The lake effect snow will continue Wednesday, Wednesday night, even into early Thursday.
A batch of intense snow squalls are likely to sweep across Upstate this morning, followed by heavy lake effect snow.

The eastbound 210 Freeway exits at Osborne Avenue, Wheatland Avenue, Sunland Boulevard, and La Tuna Canyon Road are also closed. In Los Angeles, the Burning index rating, a daily reading of fire danger, is now at 296, according to fire officials, a record.
Lake-effect snow showers Thursday will slowly shift into the primary snow belt as winds become more from the northwest, rather than more northerly in the morning. We'll see falling temperatures through the rest of Tuesday.
A winter weather advisory for snow means meteorologists believe periods of snow will cause primarily travel difficulties. Central New York could get 6 inches of snow in this round; areas to the west and north could get more. The wind chill may possibly reach minus 3 degrees by evening.
Friday: Mostly cloudy with chance of snow showers.
After Wednesday we're not quite in the clear from the cold and snowiness. Plan on hard travel conditions, including during the morning and evening commute on Tuesday.
