Areas affected...portions of New Hampshire and Maine

Concerning...Heavy snow 

Valid 040543Z - 041145Z

SUMMARY...A band of heavy snow with rates near 1-2 inches per hour
will lift northward across western and coastal Maine and New
Hampshire over the next several hours.

DISCUSSION...A large area of precipitation is ongoing across New
England tonight within an area of strong warm advection aloft on the
east side of a midlevel upper low centered over the Great Lakes
vicinity. A band of strong 850 mb frontogenesis will lift north with
time into early morning, providing ascent through a deep saturated
layer aloft. Near-surface temperatures may hover close to freezing
across portions of the region, though most of the vertical
temperatures profile will remain sub-freezing supporting snow. Given
strong forcing and a dendritic growth layer around 2.5-3 kft deep,
snowfall rates are expected to increase to 1-2 inches per hour over
the next 1-2 hours and persist into early morning.
