Those areas will see anywhere from a "dusting" to 3 to 5 inches, Zaff said, depending on the location. Lake-effect snow flurries will continue today and into the overnight hours. "It will be one semi-continuous band between now and Friday".
Those counties are expecting heavy lake effect snow and very hard travel.
Unsafe winter driving conditions from near zero visibility in bursts of heavy snow and blowing snow are expected in the snow squalls.
Lake effect snow is better organized today and continues through the start of Friday. Lake effect from Lake Ontario might dump significant snow in northern Herkimer and Hamilton counties as well as Jefferson and Lewis counties.
The weekend should start quiet with clouds increasing Saturday in advance of a cold front which is slated to move through Saturday night with some snow showers and flurries.
Southwest winds have created a lake effect snow band that stretches from Watertown, northeast into northern Vermont. A winter storm watch is also in effect for locations east of Lake Ontario, including Watertown, New York. The best precipitation chances next week come Thursday with snow, about 24 hours later than our previous forecast.
Locations from the coastal mid-Atlantic to parts of eastern New England, however, could see snow or a rain/snow mix Friday into Saturday.
We may feel more Arctic air by the middle of next week. This is not unusual since those cities typically see their first measurable snow from the end of November to mid-December.
The relatively mild weather we've seen over the last couple of days is going away.
Wednesday night: Partly cloudy skies early will give way to cloudy skies late.
Some light accumulations in the system's path are not out of the question, but details remain uncertain.
