A Messy Monday Ahead For Maine

First Call Outlook


After a dry and bitter cold weekend, the state can expect snow to start the work week. Guidance continues to teeter back and forth on ideas, but some models are finally catching up to the idea that the cold air over the region this weekend will be difficult to move before the precipitation shield arrives in the wee hours of Monday.

Southern Maine can expect 1-2″ on the ground by daylight Monday. Snow appears to move northeastward. By early afternoon, the Bangor area appears to have a couple inches on the ground. Heading onto the evening, most eastern areas are likely to see 2-5″. Northern Maine gets into the game overnight with 1-4″ at the surface by the wee hours of Tuesday.

I am still concerned about the formation of a secondary low in the Gulf of Maine that may occur in the Penobscot Bay area. If this does indeed happen, snowfall totals are likely to increase for southern Hancock County, and for Washington County from the Air Line (Route 9) south.

My other concern is for potential mixing to occur along the shorelines. If that does indeed happen, there appears that a couple inches of snow will fall before the change over occurs. Shoreline towns from Portland to Eastport may see a period of sleet, with a slight chance of freezing rain mixed in. It appears that it will be brief (1-2 hours) and likely to change back to snow before ending.

This is the first call assessment on the storm. Expect more updates on the specifics on Saturday.
