Areas of very light snow have moved into the Finger Lakes this morning well ahead of a system is interacting with a strong jet stream to produce a large area of light precipitation.

The weather system itself is very weak and, without looking at the radar, it is hard to even notice it on the weather maps. High pressure moving off the Mid Atlantic coast is helping moisten the atmosphere ahead of the low with its clockwise flow of air.

Another high pressure over the Midwest is likewise helping precipitation form by forming a small clash of air-masses with its northerly winds keeping colder air in place to the north of the storm track. The jet stream is adding some extra energy for the precipitation to form, but the low itself would not be much without these other factors helping it along.

Snowfall amounts will generally be light through Monday morning.

Periods of light snow will likely continue throughout the day and into Sunday night. There will probably be some lulls in the snow, while other times it may pick up a little bit in intensity. All in all, for most of the region, this will add up to no more than a couple inches.

Some areas to the south could see a bit more, while areas close to Lake Ontario may only see a fresh coating.

Some snow showers may linger into Monday before high pressure builds in. This high will only be around for 12 hours or so, as a new system brings some snow in late Tuesday and Tuesday night ahead of a brief push of slightly milder air.
