Good afternoon everyone,

Included with this email is an updated briefing package for the winter storm which will impact the region this evening into mid morning Monday.

Changes:
  • Winter Storm Warning now up for southern Berkshire County.  All other headlines remain the same.
  • Snow totals raised slightly, with a focus of more areas 8-10 in a stretch from N CT, across N RI into E MA. (Note: the bin on the map of 8-12" is closer to the 8-10" range).
What:    
  • Widespread now with accumulations of 6 to 10 inches across much of the region. Snow accumulations of 3 to 5 inches in Franklin and Western Hampshire Counties. Snow accumulations of 3 to 5 inches on Cape Cod, especially the Upper Cape. 
  • Impact to the Monday morning commute.
  • Risk for scattered power outages from northern CT into northwest RI as well as much of eastern Massachusetts due to heavy-wet snow.
Where:
  • Snow across all of southern New England; heaviest snow most likely over Rhode Island and central/eastern MA which includes the I-95 corridor. On Cape Cod and the islands snow is expected to change to rain during the early morning hours. 
When:
  • Snow develops in Connecticut and Western MA between 6 and 8 pm Sunday evening, and in Central/Eastern MA and RI between 8 and 10 pm. 
  • Snow ends Monday morning  between 4 and 6 AM in the west and in Rhode Island, and 6 to 9 AM in Central and Northeast MA. 
  • Heaviest snow generally 1AM to 6 AM Monday

Uncertainty:
  • High confidence in a plowable snowfall. The greatest uncertainty remains in where the band of highest snow totals will set up, as well as how far north the rain/snow line reaches. 
As always, please reach out at any time you have any questions or concerns.
