DAYS 1-5 (MAY 29-JUNE 2)
A southerly air flow will continue to bring warm and humid weather to the region today and tonight. Some fog and drizzle will be around the South Coast early in the day. A plume of tropical moisture will bring a few downpours to Nantucket first thing this morning otherwise just look for scattered light showers and sprinkles today. Some sun will try to develop, especially north of I-90, where temperatures will climb highest today due to cloud breaks and distance from the South Coast, where a southerly wind is coming off cooler water. A cold front will make its way across the region west to east during the first 12 to 15 hours of Saturday, triggering a few showers and possible thunderstorms. We’ll have to monitor for where a possible line or cluster of showers/storms may form during the late morning and midday hours of Saturday as we gain some daytime heating. Most likely chance for this is near the I-95 belt eastward. Either way, this interruption will be temporary and by later Saturday and definitely Saturday night, we’ll be clearing out and drying out, setting up for a fantastic weather day on Sunday as high pressure moves in. You may or may not recall, the last time June 1 and 2 fell on a Monday / Tuesday, we had anomalous cold, with Boston failing to reach 50 (high temp of 49) both days. This came along with rain/drizzle and a chilly northeast wind. Is that about to happen again? No. But the same 2 days falling on the same 2 days of the week this time around will once again be significantly cooler than average, just not to the extreme of last time, and this time with drier air, courtesy an air mass that originated near the North Pole. It may come along with some rain showers Monday as a disturbance crosses the region, but Tuesday will be a dry day, though we may see some cloudiness arriving as it starts to warm up aloft.
TODAY: Low clouds / fog / drizzle near South Coast and a few showers / downpours near Nantucket early morning, otherwise mostly cloudy to partly sunny with isolated light showers. Humid. Highs 70-77 south of I-90, 78-85 I-90 northward. Wind SW-S 10-20 MPH, higher gusts.

SATURDAY: Mostly cloudy to partly sunny. Scattered showers, possibly a thunderstorm, favoring morning and midday hours west of I-95, midday to mid afternoon I-95 eastward. Gradually lowering humidity. Highs 76-83, cooler South Coast especially Cape Cod. Wind SW shifting to NW 5-15 MPH, higher gusts.
