– Lake effect snow warnings in effect for counties east of Lake Ontario and the Tug Hill into Saturday evening.
– Lake snow moves into Syracuse tonight and remains close through sunrise Saturday.
– Snow retreats back to the north of Syracuse Saturday morning and eventually tapers in the afternoon.
– Everyone has the chance for light snow Sunday afternoon into Monday morning.
Lake effect on the move tonight and tomorrow morning:
For a while Friday night our winds will turn into the west-northwest. That will cause lake effect snow to move close to the Syracuse area with some moderate to briefly heavy snow. We expect that to happen between 8 and 10 pm.
Lake effect snow warnings remain in effect for Lewis, Jefferson, northern Oneida, and Oswego counties until Saturday evening.
Lake effect snow warnings are now in effect for Wayne and northern Cayuga counties through 7 am Saturday due to this southerly shift in the snow band.
Two to five inches of snowfall overnight is likely for the Syracuse area. Five to ten inches of new snowfall is expected extending from the southern shore of Lake Ontario in Wayne County and Cayuga County. There will be locally higher amounts, especially closer to the lake by Saturday morning.
Around sunrise Saturday morning our winds will shift again taking the lake effect back north to Jefferson County by Saturday afternoon. The lake effect snow should fall apart late Saturday afternoon and finally come to an end.
Outside the lake effect, we will see some sun but it will be chilly. Temperatures will reach the mid 20s but with the wind, it will feel more like the teens.
More widespread snow to end the weekend:
Our next chance for widespread snow will be on Sunday. A weak cold front will cross New York and generate light snow for Sunday afternoon and evening. This system doesn’t have a lot of moisture associated with it so we aren’t expecting much in the way of snowfall, a general trace to two inches is expected.
Busy weather pattern continues:
After a cold weekend, warmer air will work back into central New York for Tuesday and Wednesday.
We also are expecting a stronger and more complex system to pass through during this time period. This system will bring a mix of precipitation.
The center of this system will move through the Midwest overnight Monday and into Michigan early Tuesday morning. By Tuesday afternoon, it looks like we start to see some snow before winds shift from the southeast to the south, bringing in milder air and a changeover to rain. At the same time, this system does look to deepen and strengthen as the center travels over the Great Lakes.
While this system does look to have a good deal of moisture associated with it, it is too early to say how much of each type of precipitation we see. Temperature will be key.
As the low moves through eastern Canada Wednesday night, our winds shift back to the northwest which will bring colder air back into central New York along with snow showers for Thursday.
