Forecast confidence continues to increase for accumulating snow Monday night into Tuesday, with a plowable snowfall for most of the region.  Also, confident snow begins after the Monday PM commute, along with the heaviest snow occurring late Monday evening and overnight.  In addition, forecast confidence is highest for the heaviest snow to fall across western portions of MA/CT, where a winter storm watch has been posted.

Forecast confidence is lower on the duration of the steadiest/heaviest snow, which may begin to lessen as early as the Tuesday morning commute. Accumulating snow remains likely Tuesday, but perhaps lighter snowfall rates than Monday night. Also, duration of the snow may be reduced across the coastal plain of RI and MA, as snow may mix with or change to rain Tuesday. 

Nonetheless, snow covered roads & low visibility Monday night into Tuesday will make for difficult travel, especially during the Tuesday morning commute.  We hope to have more clarity on these details in later forecasts, so make sure to check back for updates.
