Mesoscale Discussion 0159
   NWS Storm Prediction Center Norman OK
   0216 AM CST Mon Mar 04 2019

   Areas affected...eastern MA...southeast NH and coastal portions of
   southern ME

   Concerning...Heavy snow 

   Valid 040816Z - 041245Z

   SUMMARY...Heavy snow will continue across eastern portions of MA and
   spread northward across southeast NH into southern portions of
   coastal ME. Snowfall rates around 1 inch per hour will be common,
   though rates up to 2 inches per hours are possible locally.

   DISCUSSION...Heavy snow will continue across eastern MA early this
   morning and rates will increase with northward extent into
   southeast/coastal NH and coastal portions of southern ME. Forecast
   soundings continue to show a saturated profile through a deep
   dendritic growth zone. Modest forcing for ascent associated with a
   weak shortwave trough ejecting over the Mid-Atlantic region and a
   band of 700mb frontogenesis over the region, in conjunction with a
   deepening surface cyclone moving offshore south of Long Island, will
   help maximize snow rates through 12z. Generally rates of 1 inch per
   hour are expected, though locally up to 2 inches per hour is
   possible, especially from eastern MA into southeast NH.
