Areas affected...Parts of southern Maine

Concerning...Heavy snow=20

Valid 241047Z - 241445Z

SUMMARY...Band of heavy snow with 1-1.5 in/hr rates to continue
across parts of southern Maine through around 14Z.

DISCUSSION...Within the left exit region of a robust mid/upper-level
jet streak and to the north of a surface low just offshore of
coastal Maine, strong low-level frontogenesis and convergence is
yielding strong mesoscale and large-scale forcing for ascent over
southern Maine. Here, a cold/saturated profile, substantial lift
within the DGZ, and light winds within the DGZ will favor a
continuation of heavy snowfall rates (around 1-1.5 inches per hour).
These heavy rates should continue through around 14Z, before the
left-exit region ascent moves offshore.
