The humidity will rise this weekend as the wind shifts to the south and southwest. Most of the weekend looks dry, but a few showers are possible on Saturday.
Clouds will be stubborn, and showers/thunderstorms will be scattered. It will not be a washout, but be on the lookout for showers anytime from early in the day through the evening. A warm front will be moving through New England. Highs will be near 80 inland, and in the mid 70s at the coast. There will be a 10-15 mph southerly wind. Overall, it does not look like a great beach day.
Scattered showers and thunderstorms are possible in the evening, but odds favor most spots remaining dry. It will be noticeably more humid, and the low temperature will be near 70. Look for low clouds and patchy fog, especially near the coast.
Low clouds and fog will burn off to hazy sunshine. There will be a 10-20 mph southwest breeze. It will be very humid, and the temperature may reach 90° for the first time this year in Providence and Boston. It will be 10-15° cooler near the coast. It does not look like a bad beach day, but you may have to wait a few hours for low clouds to erode. The temperature will fall into the upper 60s to low 70s Sunday night.
An approaching cold front will trigger thunderstorms on Monday. The threat lasts from late in the morning through the afternoon. Skies will be partly to mostly cloudy. Highs will be in the mid to upper 80s inland, and near 80 at the coast. It will be very humid again on Monday.
It looks mainly dry and warm from Tuesday through Thursday. Highs will be in the mid 80s, and lows will be in the mid to upper 60s. It will feel like the Dog Days of Summer. The best chance of a passing shower is on Wednesday.
