Thanks Canada

Last week, the pattern featured mild air moving in from our south. This week, the air mass is courtesy of our neighbors to our north, so if you’re look for someone to thank, or blame, for the chillier air, look to Canada. As the chilly air presses in the next few days, highs will struggle to crack the 50 degree mark. As lows dip below freezing for many tonight, a freeze warning is in place just outside Boston, including some of the southern suburbs. If you look at the map below, you’ll notice the freeze warning does not extend all that far inland. Sure, it’ll be just as cold there, however, since the growing season has ended in those interior locations, no warnings are put in place.

Today and tomorrow are dry, then a chilly rain settles in by Thursday afternoon and Thursday night. In fact, the storm that moves in on Thursday doesn’t bring just rain to New England. With a cold air mass in place, the precipitation likely starts as snow in the higher terrain of northwest CT and western MA. Even in the Worcester Hills, some wet flakes/sleet may mix in to start initially. Although I don’t expect much in the way of accumulations from Worcester, east, some accumulating wet snow is possible in the Berkshires and especially across the higher terrain of VT, where at least several inches will fall. In terms of rainfall, we’ll likely pick up at least 0.50-1.00″ of rain with locally higher amounts possible. The rain wraps up Friday morning with a mainly dry afternoon in place as temps near 50.

A couple more scattered showers are possible either Saturday night or Sunday. I do expect near seasonable temps Saturday – Halloween with highs in the 50s then.
