Welcome back, Winter!
The meteorologists at Plymouth State, including myself, will be bringing you your New England daily snow once again this winter. We won't start our daily forecasts until November, but with our first flakes across Northern New England possible this weekend we had to post a quick note.
Forecast: After a relatively mild day on Wednesday and Thursday, we'll see a return to colder weather this weekend as a Nor'Easter develops off the coast and tracks into Maine. This storm will be charged with some tropical moisture that will make for a wet weekend across most of New England. As the storm exits to the north through Maine, cold air will drain from Canada into New England changing rain over to a wet snow. Most flakes will fall far north and at elevation (think highest elevations of the Adirondacks, Greens, and Whites in northern New York, Northern Vermont, and Northern New Hampshire). Places as far south as Plymouth and below 1000 feet **may** see some wet snowflakes mixing with rain, but I'm not optimistic.
Science Note: The image below is a model prediction of snowfall from the Global Forecast System. Most models use a snow-to-liquid equation to calculate snowfall from liquid water. For example, 1 inch of liquid in a model typically produces ~8-10" of snow. This is one of many reasons why snowfall forecasts are often as "range" of values. The map below is using a ratio that is likely too high for this time of year and snowfall values will likely verify lower than the values you see on this map.
