As you can see, a winter weather advisory is in effect for all of Central New York for tonight.
Tonight's storm is full of moving parts and this means rapidly changing weather conditions throughout Central New York. This starts out as light snow across the region between 6-8pm. Travel conditions aren't expected to be too bad this evening. Steadier, heavier snow develops after 10pm tonight, mixing with and changing to sleet and/or freezing rain after midnight. This is time to expect the most travel trouble.
Eventually a warm front crosses the region, bringing temperatures above freezing by tomorrow morning. Travel conditions will improve, for most areas. The one exception is north and east of Utica, as the cold air is expected to linger with a wintry mix continuing through 7-9am.
Scattered rain showers are expected for most of Tuesday, with a cold front producing a round of heavier rain later in the day. Rain turns to snow tomorrow night, with accumulation expected on Wednesday.
The terrain plays a huge role in where the strongest winds will be tonight. The strongest winds (40 mph) are expected to be on the hilltops south of the Mohawk Valley. The dominant wind direction tonight is south, which is a nearly non existant wind in the Mohawk Valley in the winter. The winds will not be as strong in this area (20 mph gusts).
The extended outlook calls for much colder weather heading into the end of the week and weekend. With it, comes a few chances for snow. We'll have updates on that later in the week.
