DAYS 1-5 (JUNE 4-8)…
A split weekend. Though not totally sunny today, the feel of summer will be there as dew points are up around 60 or in the lower 60s. However, with weak pressure gradient, even though the air mass is warm, there will be a sea breeze near the coast, making it cooler there. Look for low cloudiness in some locations to start the day, even some areas of fog around Cape Cod and the Islands, with that burning away and then some pop up fair weather clouds during the day. A broad area of low pressure will track through the Great Lakes and eventually north of New England Sunday and Monday. The approach of this low will be the reason why Sunday’s weather will be overcast with periods of rain, and though any rain is needed, this particular rain is poorly timed in terms of outdoor activities, many of which are planned graduation ceremonies. By Monday, drier air will arrive and only a few instability showers are possible in the westerly flow on the back side of the low. On Tuesday, another disturbance will come along and produce the chance of a few showers and thunderstorms, but at this moves by, it will sharpen up the trough over the northeast and pull down some cool air from Canada by the middle of next week.
TODAY: Areas of low clouds favoring eastern MA and NH Seacoast and some fog especially Cape Cod and Islands early into mid morning, otherwise sun mixed with clouds. Highs 65-70 outer Cape Cod and Islands, 70s other coastal areas but warmest late morning then cooling, 80-85 interior locations. Wind light variable with sea breezes developing.
TONIGHT: Increasing clouds. Lows 55-60. Wind light SE.
SUNDAY: Overcast. Patchy rain areas in the morning favoring locations west and north of Boston. More widespread areas of rain arriving during the afternoon with a slight chance of embedded thunder. Highs 65-72. Wind SE 5-15 MPH.
SUNDAY NIGHT: Mainly cloudy with numerous to scattered showers. Lows 55-62. Wind SW 10-20 MPH.
MONDAY: Partly sunny. Isolated showers and a slight chance of thunderstorms. Highs in the 70s. Wind W 10-20 MPH with higher gusts.
TUESDAY: Variably cloudy. Late day or evening showers and thunderstorms possible. Lows around 60. Highs around 80 except cooler South Coast.
WEDNESDAY: Partly sunny and windy. Lows in the 50s. Highs around 70.
DAYS 6-10 (JUNE 9-13)…
Mainly fair but below normal temperatures June 9-11. Shower risk increases as temperatures moderate toward the end of the period.
DAYS 11-15 (JUNE 14-18)…
Another cool-down early to mid period with a shower threat to start, then drier weather. Brief wet weather may introduce warmer air by the end of the period.
