This update is just some tweaks and slightly raised snowfall amounts.
Snow begins just before and during of tomorrow morning’s commute. Snow becomes heavy by mid- to late-morning, and continues as such through the afternoon hours and into the evening commute before tapering off in the mid to late evening.
Both commutes will be impacted significantly, as well as the time in between. Slick and snow covered roads are likely, making driving hazardous – especially on untreated roads. Travel will be very poor throughout the day. Schools are already in the process of declaring closures for tomorrow.
This is a relatively high confidence forecast. The exact location of the western extent of heavy snow is still up in the air, though. This could shift a little bit west or east, but is still highly unlikely to change the situation of a widespread heavy snow, especially as it concerns CT/RI/eastern and central MA/southeastern NH. This will lead to a bit higher uncertainty for western and northern New England including southwest and northern/central NH, Vermont, northwest MA, etc.
Other Storm Hazards
Winds will be an issue in coastal Massachusetts – with wind gusts in the 30s (40s in southeast MA) causing visibility issues as well as some blowing snow; a blizzard warning is actually out for southeastern coastal MA and the south coast islands. Further inland, interior eastern MA may see this to a lesser extent.
Stay off the roads except if in an emergency tomorrow. Stay safe!
