Here we are in Mid-August, and we are finally just hitting our stride this summer. Soon festive summer weekends like this will be over, so make sure to make the best of it! High pressure sits over us today with sunshine, light winds, low humidity. Winds will be shifting onshore this afternoon keeping temps in the 70′s at the beach, with some lwr 80′s farther inland. Fair weather cumulus will start to build again with the midday sunshine, while high cirrus clouds will increase from the south during the afternoon as well. Overall, a perfectly fine day, and likely the pick of the weekend.
High altitude clouds will continue to stream up the eastern seaboard and into New England tonight with partly cloudy skies. These clouds are associated with a staled front off the coast, which will luckily stay far enough away for the weekend to remain dry. Gulf moisture is riding along this front in the Southeastern states this weekend providing for some heavy rain there. SW flow aloft with a broad eastern trough is steering these high clouds up through the region for late today, tonight and right through tomorrow.
High pressure slides across New England today. By Sunday it is off the coast and a more SSW develops at the surface. High-midlevel clouds will continue to stream through southern and central New England. Most of the time, thin enough for filtered sunshine…but definitely a more grey look to the sky Sunday. Along the south coast, closer to the front, clouds will be thicker and there is the potential for even a spot shower along the south coast towards the Cape and islands by the end of the day Sunday. Brighter skies will be found across the north. Highs again will be in the lwr 80′s inland and 70′s near 80 at the coast.
The stalled front will push farther off the coast Monday, with increasing sunshine and building high pressure once again with increasing sunshine. The trough across the north east will begin to lift out with moderating warmer temperatures into the 80′s with weak high pressure in place providing for a warmer, more humid mix of sun and clouds for the midweek by Wednesday and Thursday where high temps will be approaching 90 in spots. NW winds aloft over us will help to keep the warmest air just west of New England from penetrating farther into the region. Still, the warmest air of the month will flood in this week which be welcome to those who have been wondering where summer had gone.
We will be tracking a cold front for the end of the week. It will push through sometime late Thursday night or early Friday. Behind this front, much cooler drier air should roll in for the start of the weekend, followed by more ridging and warmer temps to end the month of August. It is a warm signal for the rest of the month of August and part of a warm pattern which will likely last into September. Still plenty of summer left in the tank. We are just hitting our stride!
