   Mesoscale Discussion 0026
   NWS Storm Prediction Center Norman OK
   1156 PM CST Fri Jan 12 2018

   Areas affected...Portions of ME...NH...VT...western MA...far
   northwestern CT/NJ...and central/eastern NY/PA

   Concerning...Winter mixed precipitation 

   Valid 130556Z - 131200Z

   SUMMARY...A wintry mix of freezing rain, sleet, and snow will spread
   eastward behind a cold front overnight. Freezing rain rates around
   0.05 inch per hour may occur in the heaviest showers.

   DISCUSSION...A surface cold front will continue moving southeastward
   across the remainder of New England and the Mid-Atlantic as a
   shortwave trough develops northeastward across these regions
   overnight. Sub-freezing temperatures behind this front will support
   a several-hour period of light to locally moderate freezing rain
   across much of New England into central/eastern NY and PA. Freezing
   rain rates around 0.05 inch per hour could occur in the heaviest
   precipitation bands, and this seems most likely across parts of
   northern NH into ME as well as portions of central/eastern PA based
   on radar trends, recent surface observations, and short-term model
   guidance. A changeover to sleet should occur fairly quickly as a
   remnant low-level warm nose erodes/cools with the approach of the
   shortwave trough, with locally moderate sleet rates of 0.10-0.15
   inch per hour possible. Finally, sleet will transition to snow as
   the low/mid levels cool further and the entire atmospheric column
   falls below freezing. Snow rates approaching 1 inch per hour may
   occur mainly across northern VT into central NY/PA around 09-12Z.
