Good morning everyone,

Here is our latest thinking on the second half of the ongoing winter storm. 

Watches/Warnings/Advisories:

NEW: 
1) Winter Weather Advisory expanded to include Washington, Kent, SW Providence, Bristol, and Newport counties in RI; Bristol and Plymouth counties in MA
2) Wind Advisory for Cape Cod, Nantucket, and Martha's Vineyard through 1 PM. 
3) Coastal Flood Advisory for eastern Essex and Plymouth counties and Nantucket this afternoon

What we expect:

Today into early Tuesday
  • Continued/ongoing snow in interior western/central MA will spread into eastern MA, northern CT and RI tonight. Lighter, more manageable snows expected in central and western MA and northern CT/RI. However, snow is expected to increase in intensity tonight into Tuesday across eastern and northeast MA, with 1-2"/hr snowfall rates possible in these areas. 
  • Impacts to the Tuesday morning commute are possible. 
Winds and Minor Coastal Flood Potential:
  • Winds will gust to 40-50 mph along coastal areas, with the highest gusts over Cape Ann, outer Cape Cod, and the coastal waters off eastern MA.
  • Storm surges of up to 2 feet are expected, but astronomical tides are low. A Coastal Flood Advisory has been issued for up to a foot of inundation above ground level possible for Eastern Essex, Eastern Plymouth, and Nantucket. 
Storm Total Accumulations:
  • In today's briefing we are showing only new snow expected today into Tuesday. We expect an additional 3-6 inches across the interior high terrain during the day today. By Tuesday morning interior locations can expect a Monday/Tuesday total of 8-12" with lesser amounts to the south and east. The heaviest snow may come Tuesday morning over far eastern MA. 
Confidence :
  • Confidence is moderately high for this second round of heavy snow Monday night/Tuesday period in eastern MA. How far west these snowbands extend is still uncertain, which could affect who sees those highest snowfall totals.
