   Mesoscale Discussion 0110
   NWS Storm Prediction Center Norman OK
   1218 AM CST Thu Jan 26 2023

   Areas affected...New England into western Maine

   Concerning...Freezing rain 

   Valid 260618Z - 261115Z

   SUMMARY...Freezing rain accumulations appear likely across portions
   of New England and into western Maine as precipitation transitions
   from snow to rain through the overnight hours.

   DISCUSSION...Recent surface observations and MPING reports from
   across far eastern NY and southwest VT show snow transitioning to a
   mix of winter precipitation and freezing rain amid strong warm
   advection in the 850-700 mb layer. Recent ASOS observations from
   eastern NY reported freezing rain accumulations of 0.17 inches with
   this activity, which is expected to spread northeast in tandem with
   the synoptic warm frontal zone. Strong isentropic ascent and
   moisture flux over the warm front, combined with warming mid-level
   temperatures, should yield approximately 1-3 hours of freezing rain
   with accumulations around 0.1 inch possible. The duration of
   freezing rain (and the magnitude of accumulations) will be dependent
   on how quickly the surface freezing line can lift north into the
   region during the 8-11 UTC period.
