Winter Storm in Northern Oxford, Maine

Precipitation began around midday on the 3rd as mostly snow with colder surface air locked in the interior. Upsloping easterly flow allowed the heaviest snow to fall through the Mahoosucs. Eventually steady snow tapered to upslope snow showers, which continued for most of the day on the 4th. Snowfall totals ranged from 8 to 12 inches.

Early on the 3rd a stalled frontal boundary was draped across southern New Hampshire and near the coast of Maine. Low pressure slowly developed along the southern end of the front and rode north along the Appalachians through the day on the 3rd. Low pressure occluded during the evening on the 3rd, with a secondary low pressure developing south of Nantucket. The bulk of the precipitation came with the initial push of warm air advection, winding down early in the morning on the 4th. However an inverted trough hanging back to the northwest of the low center extended light snow through much of the day on the 4th.
