Don’t forget, last year Boston had 4.3 inches of snow on October 30! Worcester’s first measurable snowfall averages out around November 18th, nearly right on schedule. While the first average measurable snow in Boston is November 29, we do quite frequently see flakes in the air by mid-November. If this feels early for snow, it really isn’t. No organized storms but just a general unsettled pattern which could produce a sprinkle or snow shower here and there. If you miss the snow Saturday night, there are a few more chances of scattered flurries Monday and Tuesday. You would have to be outside or driving at the time to notice it, certainly no evidence left Sunday morning. The snow may even briefly whiten the ground in parts of northern Worcester County.įarther east, towards Route 495, we are talking about some snow mixing in with the rain. The best chance of seeing snow Saturday night would be in the higher elevations of central and western Massachusetts, the Berkshires and Worcester Hills. storm sewers help to prevent flooding on neighborhood streets. Bottom line, to see the first flakes, you will have to be in the right place at the right time. Rainfall runoff, and sometimes small kids' toys left out in the rain, are collected by these drains and the water is delivered via the street curb or drainage ditch alongside the street to the storm-sewer drain to pipes that help to move runoff to nearby creeks and streams. And, temperatures closer to the coastline will likely stay a bit too warm for snow. This is a very fast moving system, lasting only 3-to-6 hours, out of here shortly after midnight. The precipitation will draw some of that colder air down, perhaps just enough to change the rain to snow in parts of our area. The air above ground level Saturday night will be below freezing while the air at the surface will be in upper 30s to low 40s. However, temperatures will not only be cooling due to darkness but also from above. This round will start as rain when it arrives between 7 and 9 p.m.
Clouds quickly return late in the afternoon and a fast moving area of low pressure brings another round of precipitation Saturday night. Saturday is a pleasant day with highs near 60 with abundant sunshine. Not enough for any widespread flooding, but some brief urban and street flooding is likely during the downpours Friday afternoon and evening. Total rainfall should be around an inch for most, perhaps up to two inches in isolated areas.
