Winter Weather Advisory Posted for Light Snow Tuesday PM

 Update:
The winter weather advisory has expanded
Tuesday 1 PM NWS Boston advisories
The forecast below looks to be on track.  Snow begins around 5-6 PM in Massachusetts.  Probably a full school day for the teachers tomorrow.

Previous discussion below.

The National Weather Service in Taunton has posted a Winter Weather Advisory for Central and Western Massachusetts.  This may extend into Northern RI and CT as well as Middlesex and Essex counties in MA.  This runs from 4 PM Tuesday until Noon Wednesday. 
NWS Boston Advisories
This is for snow, sleet and freezing rain.  Snow breaks out from SW to NE around 5-6 PM.  It gets into Worcester and Boston closer to 7

Next there will be some ice on top of this
NWS ice forecast
Yellow means icy spots expected while orange is widespread icing
Ice Storm Impacts
This may get teachers a delay on Wednesday but I won't guarantee that.  It's not something that would be called until the morning.  Next we move to heavy rain Wednesday night.  A nasty severe weather outbreak will occur in the South tomorrow as this low lifts north.  Here is the track
NWS WPC significant low tracks
Here is the project surface chart Thursday AM
WPC surface forecast Thursday AM
Here is the total precipitation through Thursday PM
WPC precipitation through Thursday 7 PM
With a strong low like that to our west we will see strong winds overnight Wednesday into Thursday.  Winds will be about as strong as they were last Tuesday.  That means some downed tree branches and isolated power outages.  I will update as needed tomorrow.  I suspect the winter weather advisories will be expanded.
