The high pressure system that brought mostly sunny skies to the area today is now shifting to the northeast. We will see increasing clouds as we head into tonight and through the morning hours tomorrow as a low pressure system moves into the region. The storm will bring precipitation developing as the day moves along. The precipitation will likely become heavy at times later Thursday evening into Friday morning, with a gusty wind developing as well.
The exact track of the storm will determine precipitation types. At this time it appears the storm will likely move just to the east of the Maine Coastline Thursday night and Friday morning. This track would keep the bulk of the precipitation falling as snow over interior Maine, while closer to the coastline a mixed bag of snow, rain, sleet, and freezing rain might occur. A storm track to the west of the current projections would bring more of a snow/rain mix even inland, while a track more to the east would hold the cold air in all across the state causing mostly snow to fall even near the coastline. There is plenty of moisture with this storm, but again, it just depends on the exact track as to where which precipitation types will fall. In locations where the precipitation remains all snow 10” or more is likely.
High pressure will briefly build into the Northeast later Friday and bring some partial clearing to our area. The next in a series of disturbances aloft will likely cross the Northeast later Saturday. The new storm aloft, will likely bring some snow showers or possibly some steadier snow to Maine later Saturday into early Sunday. Temps will turn colder Sunday, with the cold weather continuing both Monday and Tuesday.
