BOSTON (CBS) – 2021 has been a little overwhelming for snow in southern New England. Boston recorded only 0.3 inches by the end of January. For the first three weeks of the year, the Boston average is more than 10 inches!
It’s still winter and Tuesday is our next chance for flakes. While it’s not groundbreaking, it is at least a measurable accumulation.
The snow should start after 4pm. Tuesday for those in Worcester County. Interstate 495, Route 128, and eastern Massachusetts will have to wait an additional hour for the flakes to arrive. It will sink at a constant rate during the evening and night hours. Most of the accumulation occurs after midnight. The snow showers last until the Wednesday morning commute, but should taper into the morning hours.
Two inches are likely in many cities east of I-495 and expect higher totals in the west. Height will play a role in the totals leaving the Worcester Hills at the top of accumulation. That said, even parts of the southeast fair (counties Bristol and Plymouth) have a chance to see similar values.
The Wednesday morning commute is the slowest travel time. Untreated surfaces are likely to be problematic due to the accumulation of light. Even when plowing and treating main roads and highways, travel becomes difficult as temperatures stay below freezing early on.
A secondary wave will rapidly intensify in the western Atlantic on Thursday. For the coast of Massachusetts, this can result in more oceanic snow showers. A light coating and build-up are likely, but this shouldn’t be a major problem.
The more obvious result will be extreme arctic air mass for Friday and the coming weekend. Winds are expected to lash up to 30 miles per hour. This causes wind chill levels to drop below zero. Some can reach 10-15 degrees below zero by Saturday morning! Windchill notices are possible. It cannot be denied that it will be a bitterly cold weekend!
