Mesoscale Discussion 1835
   NWS Storm Prediction Center Norman OK
   1057 AM CST Sat Dec 05 2020

   Areas affected...Central Massachusetts...New Hampshire...western
   Maine

   Concerning...Heavy snow 

   Valid 051657Z - 052300Z

   SUMMARY...Heavy snow will continue to develop today with the
   heaviest rates of 1-2 in/hr expected from New Hampshire into western
   Maine.

   DISCUSSION...Temperature profiles are on the warm side over much of
   the area as of 17Z, but precipitation has changed to snow especially
   above 1000 ft. As deep frontogenetical forcing northwest of the
   surface low persists and shifts slowly north, the heavier
   precipitation will continue to cool the column, with rain changing
   to snow, especially in the higher elevations of NH into western ME.
   Hourly liquid-equivalent rates of 0.10 to 0.25 have already been
   measured near the bright-banding areas, suggesting 1 to 2 in/hr
   rates will be possible.
