Forecast discussion: A frontal boundary near the coast of North Carolina Tuesday morning helped to bring some light snow throughout the day in eastern Massachusetts. Snowfall totals ranged from a coating in Boston to as high as 2 inches in Framingham, in Middlesex County. However, the average amount for this storm was only about an inch.
We will continue to see some light snow showers and flurries continue into the evening, before stopping before midnight. High pressure over the Southeast U.S. will help clear our skies overnight, and bring bright sunshine on Wednesday.
However, we will not be returning to any sultry high temperatures. In fact, a cold dome of air from Canada will come into the region tomorrow night, thanks to an Arctic cold front. The front will be dry, so I am not expecting any precipitation. However a passing flurry is possible. After it passes, temperatures will not reach freezing for highs, and lows will fall into the middle teens.
This trend will continue until the weekend, where I will be watching the computer models carefully. But, the models are developing a possible coastal storm for us this weekend. On Friday, the low develops over eastern Texas and gains strength. By Saturday, overcast skies are expected, as moisture from the system reaches New England. The precipitation will start off as some light to moderate snow, but warmer air will begin to move into the region. So, the precipitation will slowly change over to a mix of sleet and rain, before changing over to plain rain by the late morning on Sunday. It is possible it will return to snow showers by the late evening, before ending early Monday morning. We will then return to drier weather to begin the new workweek.
