Metro Boston, North Shore and Metro West: It was a slow process on Thursday with respect to getting the clouds to give way to sunshine through the morning but eventually we had a fair amount of afternoon sun and a more comfortable day overall. A pop up shower or two developed late in the afternoon and evening, especially across sections west and southwest of Boston, but these were light and were gone around sunset. Temperatures managed to return to seasonable levels, mainly in the low and mid 80s. A light sea breeze developed along the shore as expected.
Those pop up showers were the result of an upper level trough that has now shifted east of the area. High pressure will be the main weather feature over the next few days as it builds into New England and promises to bring us delightful conditions through at least Saturday night, possibly Sunday as well.
Expect plenty of sunshine and a beautiful day overall on Friday with low humidity and light winds. Afternoon temperatures reach the low 80s across the interior, mid to upper 70s along the coastal plain. Coastal winds turn light onshore in the afternoon, otherwise light and variable.
Other than a few clouds during the evening Friday night is expected to be mainly clear and very comfortable as the mercury falls into the mid 50s inland to the low 60s in Boston. Light and variable winds, becoming calm.
Saturday and Saturday night feature fair weather with a generally partly cloudy sky cover. Winds will be off the ocean once again making it cooler along the shore, highs there in the mid to upper 70s, otherwise in the low 80s across the interior. The overnight lows hovering near 60 degrees.
Now on Sunday there remains a bit of a question on what happens to our south with a low pressure system. Some computer models take this harmlessly out to sea while one or two models hint at a track closer to southeast Massachusetts. With this in mind the sky cover may range from partly sunny to mostly cloudy and this of course will depend on how close the system gets to the coast. For now we are sticking with a partly cloudy day, highs around 75 coast to 80 inland.
Sunday night into early Monday may remain partly to at times mostly cloudy, depending on how close the track of the offshore disturbance gets to us. Lows Sunday night near 60.
Monday may start with clouds but the trend should be for developing sunshine and highs ranging from near 75 on the coast to 80 inland.
Monday night through Tuesday night remain fair and seasonable. Milder, highs in the low to mid 80s. Lows at night in the 60s.
North Shore beach outlook:
Friday: Sunshine and very pleasant. Light onshore breeze with high temperatures in the mid 70s. Water temperatures in the mid 60s. High tide late in the afternoon. High UV Index. There is a moderate risk of rip currents with a 2 to 4 foot surf.
