Nor'easter pulled into town this afternoon, and we got right down to business in many spots. Snow was flying all around Greater Boston, winds picked up all along the coast, and the sea foam was flying along the beaches.
Then the reports started coming in: radar was showing snow all the way to Concord, NH, but not a flake was flying north of Rt. 2 or in the Merrimack Valley!
As is typical with nor'easters, a pocket of cold, DRY (this is key) air was sucked into the storm, setting up shop in the aforementioned areas. This dry air chewed up the snow as it tried to advance north. The bottom line is we've fine-tuned the heavier snow amounts:
It's slam-city for the suburbs south and west of Boston. Roads are slick and visibilities are poor. Drive safely if you're working the 3rd shift!
Timeline remains the same. We're in the teeth of the storm now in terms of wind and precipitation. After midnight, the wind will be the main concern. Most of the precipitation will slow down, so the morning commute looks better than tonight's.
Wind will still lash the coast/Capes/Islands. Gusts will top 50 in many spots - even after midnight.
By daybreak, there will be less wind, less snow/rain and temps in the low/mid 30s. Watch out for slick spots!
Better all around by tomorrow afternoon. Storm will be pulling away, skies will even be clearing after nightfall. Then, in typical fall fashion, the pattern shifts and the weather warms through the weekend.
