The picture is becoming clearer on our coastal low for Wednesday night and Thursday. Throughout Tuesday, our latest weather model runs continue to show a shift to the east (or out to sea). This will mean 2 things... 1) colder air will be in place across our region and 2) less moisture will be available. So with that, this system looks like a light snow event at best. Really, just a taste of winter weather for our region.
Location will play a part in this system, as it will not be a widespread snow. It looks as though the farther south or east in VT you are, the better shot you have at getting some snow. This also holds true for interior NH. Overall, snow totals look to be light ranging from a trace for areas west of the Green Mountains, 1-2" for areas east of the Greens, and up to 3" or so along the Green Mountain spine, as well as the northern White Mountain region.
With this "colder" change, it also appears as though less "mixed precip" will occur. There is still some warm air getting into the mid levels of the atmosphere. This would mean some changeover to sleet, or even plain old rain showers as daytime temperatures climb to the upper 30s to near 40 on Thursday afternoon. Again, overall amounts will be light with less than .10" of rainfall, mainly in the warmest valleys of VT and NH.
