Storm track / timing still in question
After a quiet day Saturday, Sunday starts off with high pressure exiting to the east and a southwest flow picks up. The region stays dry until late Sunday afternoon into the evening as low pressure advances up the coast. Far southern areas start off with potentially a mix of snow and/or freezing rain (rain along the immediate shorelines) and then precipitation evolves over the rest of the state overnight into Monday.
We're playing a timing game here as a negatively tilted trough is going to intensify the storm as it passes through into the Canadian Maritimes. If the surface low slows, there is a chance for more precipitation. Track also plays a factor in amounts, which could mean less or more.
For now, I am thinking anywhere between a dusting to about 4" of snow, with the higher amounts over eastern Maine.
There is a good bet that the Monday morning commute could be greasy everywhere.
I will update on this Saturday with finer details.
Outlook through Wednesday
After the storm passes through on Monday, an arctic front passes through the region bringing snow showers / squalls and gusty wind on Tuesday. Below normal temperatures resume for Wednesday.
I apologize for the brief update... I will have a more detailed discussion Saturday.
