   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.
