Sneaky trough to watch out for
I look at this model loop and see a couple key things to watch for. First, the storm passing to the southeast blowing up as it tracks along Georges Bank into Nova Scotia. Second, the flaring of a inversion band tail that may add a couple of bonus inches over central parts of the state. As we have seen this winter, these inverted troughs have a mind of their own. Some places get little to nothing. A couple miles up the street, a whole different story.
It could be a bit slick in spots for the Wednesday morning commute for all areas but the far north, so plan accordingly.
The western border region with Quebec and DownEast areas have the best chance for 2"+ of snow from this event. Depending on if and where any banding sets up over central areas may bump the totals up into that range, also. For most of southern areas, it appears to be flakes to an 1". If the storm jogs a bit northwest, it could be 1-2" for Portland.
Storm drags down bitter cold from the north
As the storm intensifies over Atlantic Canada and dumps copious snow there, it hauls cold air down from the northwest Wednesday night into Thursday morning. Wind gusts 20-30 mph will drop wind chill values below zero for most locations, and blow snow around in areas which may cause whiteout conditions through midday.
Thoughts on the weekend
One thing is for sure is there will be a storm, and it will likely bring some impacts to the region. Models are again aggressive with warm air overtaking the cold air at the surface, which I have a difficulty believing. With that in mind, it sets up potential for a period of freezing rain over interior areas. I don't want to sound alarmist, but it could be something to be concerned about.
