DAYS 1-5 (SEPTEMBER 14-18)<\/p>\n\n\n\n
A cold front will complete its trip across our region by moving offshore later this morning \/ midday, putting an end to the last of the showers currently (as of 7 a.m.) over far southeastern MA. While some other clouds may stream across the sky from southwest to northeast in the mid and upper level winds behind the front, the balance of the day is going to feature fair weather, mild air, and the arrival of much lower humidity. Ah! This drier air mass will hang around for a while too, and will actually be a player to some degree in our Saturday forecast, regarding Lee’s passage. First, we’ll enjoy a nice day on Friday as high pressure sits over the Great Lakes and sends us nice Canadian air on a northwesterly wind. As this happens, Hurricane Lee will be making its way northward, accelerating, and weakening, but also expanding in size as it begins the process of tropical to post-tropical transition. Lee will still be at hurricane strength on Friday and on its projected path it will make its closest pass to our region during the first two thirds of the day Saturday, the center still well offshore. An interaction with a low pressure trough to our west will give Lee’s path a little wiggle to the west, just enough to bring its expanded wind field into our area, of course strongest along the coast, especially Cape Cod. The cloud shield associated with Lee will already have started to spread north and northwest into our region later Friday, reaching its maximum Saturday morning to midday. This is also when Lee’s rain shield has the greatest chance of impacting the region. The most likely location to see any appreciable rainfall is Cape Cod. While the rain shield may make its way across the coastal plain and possibly as far as the I-95 and maybe even briefly the I-495 belts, it will also be battling the aforementioned dry air in place over our region, which will eat away at the western edge of it. Essentially, rainfall from Lee will be a non-factor except for on Cape Cod. The other more important factor, already ongoing and continuing through Saturday, will be the rough surf and large ocean swells along the coastline. As previously mentioned, use caution if you have plans that take you sea-side or into the coastal waters during the next few days, through the weekend. Although by Sunday and definitely Monday these conditions will be subsiding. My expectation for Lee is that he will have weakened to a tropical storm during the transition to post-tropical while passing our latitude and make a landfall as an “almost” post-tropical storm on the western side of Nova Scotia later Saturday, before heading off through Atlantic Canada as a gusty wind and rain storm. Keep in mind that well-in-advance nice sunset prediction for our region late Saturday. We may be able to add Friday to that prediction depending on the advancing cloud shield ahead of Lee. But at least one of those is going to produce nicely. Hold me to it! Our weather improves quickly Saturday evening and is stellar for Sunday with fair weather, low humidity, and a tolerable breeze. A trough from the west moves in for Monday with more clouds and the chance of some rainfall again in the region, but at this time it does not look like a heavy rainfall event.<\/p>\n\n\n\n
TODAY: Clouds and showers linger in the Cape Cod region for a while this morning. Otherwise, a sun\/cloud mix. Highs 71-78. DP falling 60s to 50s. Wind W 5-15 MPH.<\/p>\n\n\n\n
TONIGHT: Clearing. Lows 55-62. DP ~ 50. Wind WNW 5-15 MPH.<\/p>\n\n\n\n

FRIDAY: Cloudy. Rain arrives Cape Cod. Lows 57-64. DP lower-middle 50s rising to near 60 Cape Cod. Wind N 5-15 MPH inland, 15-30 MPH coast, higher gusts.<\/p>\n\n\n\n
SATURDAY: Cloudy through midday including rain likely Cape Cod and a chance of rain eastern MA & NH Seacoast, then increasing sun especially western areas during the afternoon and maybe into eastern areas later on. Highs 66-73. DP middle 50s to lower 60s, highest coast, falling again later. Wind N 10-20 MPH inland, 20-35 MPH coast, strongest Cape Cod, including higher gusts through midday, diminishing gradually thereafter.<\/p>\n\n\n\n
SATURDAY NIGHT: Clearing. Lows 50-57. DP falling to 40s. Wind NW 5-15 MPH.<\/p>\n\n\n\n

SUNDAY NIGHT: Increasing clouds. Lows 50-57. DP upper 40s. Wind W up to 10 MPH.<\/p>\n\n\n\n
MONDAY: Mostly cloudy. Showers likely. Highs 67-74. DP rising to near 60. Wind variable to S 5-15 MPH.<\/p>\n\n\n\n
DAYS 6-10 (SEPTEMBER 19-23)<\/p>\n\n\n\n
High pressure establishes control as we count down the final days of summer to the arrival of Autumn (equinox September 23) with a long stretch of mainly fair weather and temperatures near to slightly above normal.<\/p>\n\n\n\n
DAYS 11-15 (SEPTEMBER 24-28)<\/p>\n\n\n\n
While lower confidence further out, the indications are for high pressure to be dominant with a mainly dry pattern and temperatures near to above normal.<\/p>\n","protected":false},"excerpt":{"rendered":"
