Forecast: Couple Humid Days Before Drier Air Returns; Sunday Is Best For Beach-Lovers

It was muggier last night with clouds and a flow of milder air from the south.

This morning we are watching an area of rain to the south. It appears most of the heaviest rainfall will stay south of Boston, where there is a flood watch posted.

A warm front bringing the rain serves as the dividing line between the comfortable air 24 hours ago and the more humid air now in place. This boundary is the focal point for the rainfall, and because of the tropical nature of the air to the south, the showers can be heavy.

In addition to the rain, I can not rule out a thunderstorm with gusty winds or even a small tornado or spin-up. Such an occurrence is most likely over the south coast, but even there, it's not very probable.

By the evening commute the rain should have ended, and I expect a warm and muggy night ahead.

Saturday brings a cold front and drier air. This may kick off another round of showers and storms in the afternoon or evening, and some of them could be strong. Once the front leaves the region the air will dry out and you'll no longer be bothered by humidity.

Sunday is the pick of the weekend with abundant sunshine and warm temperatures. It will be a great beach day.
