Soupy air is here to stay folks. Today we saw some of the byproducts of that humidity: a dense morning fog bank and a few downpours across Western Mass.
While the downpours were feeble and fleeting, the fog was not. It lurked offshore and occasionally darted into the city during the afternoon. Elsewhere, it was less forgiving: swallowing up the North Shore and the Seacoast of New Hampshire without so much as a warning. Visibilities were down to almost arm’s length by late afternoon.
Expect that fog to expand and continue to be quite dense overnight. Some will wake to a sky that’s socked in. Others, a lighter fog. I’ve been in this business for over 20 years, and I’m not one to attempt to forecast the subtleties of a mass of tiny water droplets. The cloud physics are relatively simple, but the way it moves on the ficklest of wind can be befuddling.
Downpours, on the other hand, are a little more concrete. We will see them sprout tomorrow ahead of a big, juicy front. Most of us will see quick-movers from Worcester to Haverhill and down to Danvers and Boston through the early part of the day. In the afternoon, they’ll be more numerous in those same areas. South of the Pike, the picture isn’t as clear. Most areas should stay dry the closer you move to the Canal. The caveat here: not a lot of sun. Low clouds will be tenacious tomorrow.
The weekend has issues. That same weather system will be upon us with more downpours – and possible flooding rain – on Saturday. Sunday may see a lull from time to time before we bring in more showers in the afternoon. There should be a bit of a temperature slide as well on Sunday as our winds turn more to the east/northeast – an notoriously cooler direction for us.
