DAYS 1-5 (AUGUST 4-8)<\/p>\n\n\n\n
First, a little on current weather at sunrise this Monday morning. Across the WHW forecast area, the cool spot is Martha’s Vineyard at 46 – the only reporting station in the region under 50. The next-coolest is New Bedford at 52. Everywhere else it ranges from 53 to about 60. Why is this the case? High pressure is centered right over the South Coast region, with calm wind. The further north you go, you are further away from the calm center, and there is a light southwesterly wind keeping the air more mixed, and the temperature up a little compared to the calm locations. This is a short-lived but fascinating fair weather phenomenon to start your week. Canadian wildfire smoke is again a significant player in our current and upcoming weather, with a significant smoke plume aloft currently, and set to last for a couple more days, though showing a gradual thinning trend. Today, there will be some pockets of smoke closer to or at the surface too, reducing horizontal visibility and impacting air quality. Later this week, the plume will depart, but we may not be done with such smoke this summer. Meanwhile, our weather will be dominated by high pressure all week – first, one to the south which makes today the warmest day of the week, and second, a new high from Canada which provides a slight cool-down toward midweek, before that one itself sinks more to the south and east overhead then south of here, allowing a slight warm-up to return later in the week. Other than a few pop up showers or thunderstorms potentially occurring in the hills of southwestern NH and central MA Wednesday afternoon, we are looking at dry weather through the next 5 days. Elsewhere, the tropics are a little more active, but outside the MDR. TS Dexter formed last night from an old non-tropical low off the US Southeast Coast, but will move harmlessly out to sea. A second system is being watched for development later this week, but for the time being is no immediate threat or player in our weather.<\/p>\n\n\n\n

TUESDAY NIGHT: Partly cloudy. Additional smoke aloft. Lows 61-68. Dew point near 60. Wind NE to variable under 10 MPH.<\/p>\n\n\n\n

DAYS 6-10 (AUGUST 9-13)<\/p>\n\n\n\n
High pressure shifts into the western Atlantic and a more southerly air flow gradually develops. Fair weather should hold through the August 9-10 weekend. A better chance at the development of some showers and thunderstorms beginning early next week. Humidity and heat gradually increases, but not to extreme levels.<\/p>\n\n\n\n
DAYS 11-15 (AUGUST 14-18)<\/p>\n\n\n\n
Overall pattern features high pressure off the East coast, promoting warmer, more humid weather with a slightly increased chance of showers and thunderstorms with more moisture moving up from the south, potentially enhanced by any disturbances moving through from the west.<\/p>\n","protected":false},"excerpt":{"rendered":"
