Areas affected...portions of eastern Maine

Concerning...Heavy snow=20

Valid 241846Z - 242215Z

SUMMARY...Heavy snow will continue across eastern Maine for the next
few hours, with 1 inch/hour snowfall rates possible.

DISCUSSION...Ahead of an approaching stacked cyclone over the Great
Lakes, low-level warm-air/moisture advection over eastern New
England is providing increased ascent amid a sub-freezing
troposphere. Saturation of the dendritic growth zone is supporting
heavier snowfall, which has been observed over NH into southwest ME
over the past couple of hours. Current thinking is that the primary
snowband along the NH/ME border will continue to benefit from
low-level convergence along an axis of 850-700 mb frontogenesis,
which characterizes the nose of the stronger WAA within the
dendritic growth zone. 1 inch/hour snowfall rates will be possible,
as also shown by the consensus of the more recent high-resolution
guidance.
