Winds turning a bit more into the northwest has caused lake effect snow to shift back south of Syracuse and weaken. The flurries and brief squalls we're expecting will be on and off throughout the afternoon. There is likely to be 1-4" of new snow in the most persistent snow through around sunset.
There is a lot of lake effect activity taking place to our west on all the other Great Lakes so we think it will be an issue for parts of central New York tonight into Saturday. By the evening, a lake effect band will reorganize as winds start to transition back into the west and affect the Syracuse area. The lake snow won't be around Syracuse for long this evening but there could be a quick 1-3." As we mentioned before, winds will be turning into the west and that is why we think this renewed area of snow won't stay near Syracuse long. The lake effect will be a bit stronger as it moves north through Oswego, Lewis and nothern Oneida counties so there could be 3-6" of new snow overnight.
Regarding the weekend, lake effect will be well north of Central New York on Saturday as winds shift into the southwest, moving any lake effect up towards Watertown and Massena during the day. Outside this lake effect there will just be flurries and it will remain a bit chilly.
For Sunday afternoon, snow will become more widespread across the area with this new system, an area of low pressure. This low is not all that strong but it will move almost right over central New York. Signs are this system could bring us a period of squally weather later in the afternoon. Once we hit Sunday evening, winds will shift back to the northwest providing a good setup for another shot of lake effect Sunday night into Monday morning. Temperatures will remain cold throughout the weekend into the beginning of next week.
