COMMENTARY
The Summer Solstice occurred at 6:07AM EDT so it’s now officially summer by astronomical standards, lagging behind almost everyone else’s definition of the start of summer, and proving, though probably to no real benefit, once again why it doesn’t do us good to rush the seasons. Interesting how we’ve decided to ignore the real in favor of the made-up, but that’s how we do it in society I suppose.
DAYS 1-5 (JUNE 21-25)
A disturbance that passed south of the region overnight exits early today with no more than few rain drops around Nantucket, but a frontal boundary coming down from the north along with a developing sea breeze will set up a wind convergence area and may trigger a few showers and maybe even a thunderstorm this afternoon and very early evening anywhere from the Boston and Worcester metro areas southward. High pressure will control the weather Friday but a light onshore flow will keep it on the cooler side of average. The weekend will be somewhat unsettled but not a washout. I would not cancel any plans at this point. We’ll see a warm front pass through the region by Saturday night, and ahead of it we’ll see abundant cloudiness and patchy rain, but a good amount of this rain may peel off to the east and push through southeastern areas from Saturday morning to early afternoon, leaving much of the region rain-free. Humidity spikes by early Sunday and by later Sunday a cold front will be moving through the region bringing a fairly widespread shower risk. Drier air arrives Monday but one additional disturbance passing through may still trigger a few showers, but that being 5 days away is far from a certainty. Forecast details…

DAYS 6-10 (JUNE 26-30)
Expecting mainly dry weather for this period but will watch for small disturbances coming along a weaker jet stream in a general west to east flow. Temperatures near to above normal.
DAYS 11-15 (JULY 1-5)
Much of this period looks dry with minimal shower and thunderstorm threat but always need to watch for disturbances with the jet stream not too far to the north. Temperatures generally above normal with a high pressure ridge in the eastern US.
