Weather: Lake effect continues for now (12/7/2017)

A lake effect snow warning is in effect in St. Lawrence County and a winter weather advisory is in effect in Franklin county, NY; both go until 7am Friday. Generally, additional accumulation is expected to be light (1-3+") as the lake effect band shifts north and south through Friday midday. The largest amounts (3-7+") will be in southern St. Lawrence county. Still be careful in and out of Tupper Lake along route 3 and 30. The added moisture will keep a chance at snow showers over northeast New York and northern Vermont tonight and Friday morning but accumulation (dusting to 2") and impact will be very little. Last but not least, the more south you go you'll be mainly dry in places like the Upper Valley and southern Vermont; overnight lows everywhere drop into the middle & upper 20s. Friday, lake effect snow gradually ends, light leftovers may linger near Massena into the early afternoon. Elsewhere, skies partially clear with highs getting into the middle & upper 30s.

The weekend will start dry and quiet. Saturday will feature a mix of sun and clouds, highs will be in the mid 30s. Sunday, we're looking at widespread light snow showers. Also, the idea of a coastal storm throwing snow back this way is returning, especially for eastern Vermont & New Hampshire. Timing ot this would be Saturday night & Sunday. We're not expecting big accumulation with the current track of the storm, perhaps 2-4" with the highest amounts east and south. However, if it keeps jogging back west, those totals could go up. Meanwhile, highs on Sunday drop into the upper 20s & low 30s. We keep a chance at passing snow showers Monday. Tuesday is getting more interesting. There are a few pieces of energy that are coming together that will likely give us our first widespread measurable snow. Those who are still waiting for their first inch will probably get that and then some by Tuesday at the latest. It's still too early to dig into possible amounts but shovels and plows may be necessary. Wednesday & Thursday, we keep isolated snow that gradually tapers off and temperatures drop like a rock. Highs will be lucky to get into the 20s both days with lows in the single digits and teens. Feel like December yet?
