Subtracting Today, Adding This Weekend
Posted by Chris Lambert
Temps today start off below freezing, and that means Thursday's snowmelt refroze overnight, slickening the sidewalks and driveways this morning with black ice. Give that sun a couple hours to work, and temps jump above freezing, the ice thaws out and snow resumes it's subtracting mode. With high temps near 50 this afternoon, shrinking snow piles is the theme of the day.
Just because temperatures near 50 today, doesn't mean it won't snow soon. This is New England, just wait a day, you know Mother Nature changes her mind quite often and quite abruptly.
Change start working in tonight as a weak cold front slides in. Clouds increase, and perhaps a bit of snow and rain breaks out after midnight. I wouldn't surprised to see minor accumulations north and west of Route 128 early Saturday morning. Then some breaks of dry weather enter from Saturday morning, into the early afternoon. After that, more rain and snow redevelop Saturday afternoon. At first, it's mainly rain inside 495, but as winds turn north, and sunset approaches, temps cool, and rain turns to snow. By Saturday night, we're tracking an ocean storm just far enough offshore to send the brunt of the storm out to sea, but close enough to produce some steady snow overnight, into early Sunday morning. If this sounds like a complicated forecast, that's because it is. Snowfall accumulation is tough to pin down, but I'd plan on several inches of snow by Sunday morning, and that'll be enough to get those shovels and plows back out.
Cold air rushes in Sunday afternoon, but the core of the cold is short-lived and that means next week looks fantastic for skiing on school vacation week!
