Well for a few days I’ve been calling for dry weather Monday and Tuesday, and for the most part that continues to be the case. However, a small tropical-type low pressure area will come northward in the western Atlantic on Tuesday and Tuesday night and scrape Cape Cod and the Islands with a shield of rain during this time. I’m not expecting this rain to make it all the way to Boston. It should stay just offshore. Watching it, in case…
As August gets underway, warmth and humidity will be the general rule, along with a daily risk of showers and thunderstorms, but this risk will not be too high, and much of the time any given location will be rain-free. We do, however, have to watch for the possibility of one more batch of tropical moisture near Cape Cod and the Islands late Thursday or Thursday night.
