   Mesoscale Discussion 2188
   NWS Storm Prediction Center Norman OK
   1142 AM CST Tue Dec 03 2019

   Areas affected...portions of northern NH into ME

   Concerning...Heavy snow 

   Valid 031742Z - 032145Z

   SUMMARY...Heavy snowfall with rates of 1-2 inches per hour will
   continue to impact portions of northern ME into northern NH through
   early evening. The greatest snowfall rates are expected across parts
   of central into northern ME.

   DISCUSSION...Heavy snow associated with an intense coastal low
   offshore of ME will continue to pivot north/northwest through the
   21-00z time frame. Strong isentropic ascent is evident in water
   vapor satellite loops as the warm conveyor wraps around the
   north/northwest sides of the cyclone. Forecast soundings across
   northern portions of ME continue to indicate deep, saturated
   profiles through the dendritic growth zone. This will aid in
   efficient snowfall production, further aided by strong ascent and
   warm advection in the 850-700mb layer. The heaviest snowfall rates
   are expected from central into northern ME through 21-00z. Farther
   west, periods of heavy snow are possible into northern NH, aided by
   orographic influences. Though stronger forcing will be shifting east
   of this area over the next couple of hours.
