DAYS 1-5 (MAY 5-9)…
All is on track as a broad area of low pressure has spread its canopy of cloudiness across the region. Initial rain from this system will be spotty, light, and mostly northwest of Boston through early afternoon, and then a couple to a few rounds of moderate to heavy rain will cross the region from southwest to northeast later in the afternoon into tonight, with a good chance of some embedded thunder too. There will be no severe storms, however, as that support for that activity will be far to the south, across the Middle Atlantic States. Behind this rain, drier air moves in Monday on the south side of this elongated low, and it will be rather warm, but still unstable enough so that a shower or thunderstorm may pop up during the day. Another disturbance comes along with a risk of additional showers later Tuesday. A shot of unseasonably cool air will follow this for midweek, with a few instability showers Wednesday and dry weather Thursday.
TODAY: Overcast. Areas of fog Cape Cod early. Scattered very light rain mainly northwest of Boston at times through early afternoon. General areas of rain, some moderate to heavy, and a chance of embedded thunder, moving in from southwest to northeast later in the day. Highs 64-72, coolest South Coast. Wind SE 5-15 MPH.
TONIGHT: Overcast through midnight with episodes of rain and possible thunder. Breaking clouds overnight. Lows 57-64. Wind S to SW 5-15 MPH.
MONDAY: Partly cloudy. Isolated showers or thunderstorms possible. Highs 78-86. Wind W 10-20 MPH.
