Heavy Snow — Central Somerset, Maine

2018-11-13 · Central Somerset, Maine

Event narrative

Snow overspread the western Maine mountains early on the morning of the 13th. Snow gradually increased in intensity, with moderate snow developing by mid-morning. In the afternoon temperatures began to warm and snow mixed with rain at times, especially at lower elevations. During the mid-afternoon steady precipitation came to an end, though snow and rain showers lingering into the late afternoon.

Wider weather episode

A rapidly developing low pressure formed off the Mid Atlantic coast and tracked through southern New England. Forcing resulted from an open wave aloft, which limited intensity and duration of precipitation. Despite a track near the coast, a seasonably cold antecedent air mass allowed precipitation to begin as snow before mixing with and changing to rain at the coast into the foothills. Precipitation stayed mainly snow in the mountains.
