Discussion…

High pressure retains control of the weather today, but as its center will have slipped off to the south the door is open for a warmer air again, and you’ll notice that today with a southwesterly wind. This will continue into the weekend but with an increase in humidity. A cold front will slowly approach the region by late in the weekend, but both days will carry a chance of afternoon showers and thunderstorms, though they will be on the isolated to scattered side, with many areas likely to remain rain-free. That front will be in the area Monday and there may be some additional showers around, and another front will approach Tuesday with yet another chance of showers and thunderstorms. Sound like a wetter pattern? Not really. The area’s drought has been upgraded to moderate to severe and this will remain in place for a while.

The vast majority of this 5-day period will be rain-free. Temperatures near to above normal through mid period cooling to near to below normal late in the period.

DAYS 11-15 (AUGUST 31 – SEPTEMBER 4)

A front or disturbance should be passing through around September 1 with a shower risk, otherwise high pressure will be in control the majority of the time with mostly dry weather. Temperatures warm up to start the period, then cool down mid period before warming up again.

DAYS 1-5 (AUGUST 20-24)

Discussion…

High pressure will control the weather the next 3 days, starting out with a coolish morning today. You will notice a warm up and a slight increase in humidity as we progress toward and into the weekend. The risk of a pop up shower or thunderstorm is very remote on Saturday, but there will be a better chance of showers and thunderstorms developing during Sunday afternoon as a cold front approaches. This front will still be in the vicinity Monday when more cloud cover and additional shower activity is possible.

DAYS 6-10 (AUGUST 25-29)

A weak trough passes with a chance of a shower or thunderstorm August 26 and a stronger cold front moves through around August 28 with a shower and thunderstorm threat. The vast majority of this 5-day period will be rain-free with overall temperatures near to above normal, though a nice shot of cooler air may be here for the end of the period. As far out as I can tell I don’t see any East Coast threats from the tropics at this time.

DAYS 11-15 (AUGUST 30 – SEPTEMBER 3)

High pressure is expected to be in control with generally fair weather and near to above normal temperatures for much of if not all of this period.

DAYS 1-5 (AUGUST 19-23)

Discussion…

High pressure will be the main player in the weather for a good part of this 5-day period, but not the only player. A weak trough will pass through the region from west to east today and be enough to trigger some cloud development and a possible pop up shower in a few locations. This actually brings in a slight reinforcement of cooler/drier air through early Thursday, which will result in that hint of the coming autumn in the air to start the day Thursday. But you’ll very much know it’s still summer as we move through the next several days to a return of a little more heat and humidity, especially by the weekend. By Sunday, we’ll put the chance of a shower or thunderstorm back into the forecast as a cold front approaches the area. Another reminder to be cautious with any outdoor open flame as we’ll be seeing fire danger higher than average due to long term dry conditions.

SUNDAY: Partly cloudy. Chance of a shower or thunderstorm, mainly late in the day. Highs 83-90. Dew point middle to upper 60s. Wind SW 5-15 MPH.

DAYS 6-10 (AUGUST 24-28)

The cold front that moves into the area at the end of the coming weekend will hang around next Monday (August 24) with a risk of showers and still humid air. High pressure builds in with generally fair weather and near to above normal temperatures for the middle of the period before an approaching front brings a shot of high humidity and a chance of showers and thunderstorms around the end of the period. With some medium range guidance predicting the potential for a tropical system off the East Coast by late in the period we should also pay attention to that. It may end up as no threat at all, but you don’t discount anything this far in advance in hurricane season.

DAYS 11-15 (AUGUST 29 – SEPTEMBER 2)

High pressure is expected to be in control with generally fair weather and near to above normal temperatures for much of if not all of this period.

DAYS 1-5 (AUGUST 18-22)

Discussion…

A trough passing through the region overnight and very early this morning triggered some showers and even a few rumble of thunder in the region, but it now moving offshore and opening the door for a much nicer day as a drier westerly air flow arrives. High pressure builds in with great summer weather for the remainder of this period, starting out seasonably warm with fairly low humidity for August. You’ll then notice a bit of an increase in heat and humidity as we get to the start of the weekend. One thing to keep in mind, despite some recent showers, the overall pattern remains very dry, and the drought will continue to worsen. Fire danger will be high as well. If cooking outside, be sure not to use grills near brush that can easily ignite, and never leave a grill or especially an open flame unattended.

Details…

Discussion…

The maritime air feel of the weekend lingers as we start the new week today, but we’ll start to lose that as low pressure pulls away from the region. A brief wind shift to a more southerly direction by evening precedes a trough / cold front which may kick off a few showers and even a thunderstorm as it crosses the region late tonight and early Tuesday. Behind this comes a drier westerly air flow and fair weather. The high pressure area that builds in by the middle of the week will stay around into late week too with some great late summer weather resulting.

Details…

DAYS 6-10 (AUGUST 22-26)

Higher humidity and showers/thunderstorms August 22-23 weekend, and a frontal boundary hanging nearby may keep some showers around into August 24 before high pressure builds in and returns fair weather to the region for the remainder of the period.

DAYS 11-15 (AUGUST 27-31)

High pressure is expected to be in control with generally fair weather and near to above normal temperatures for much of if not all of this period.

Discussion…

The second of two low pressure areas will pass south of New England during the next 24 hours (through early Monday) before moving out to sea. This, combined with high pressure to the north, will keep a cool northeasterly air flow going across the region, and this second low pressure wave will be close enough to cause some rainfall mainly over the South Coast and southeastern MA, though patchy light rain is possible elsewhere, from this evening through early Monday before that chance drops off as the wave moves away. We will also continue to see rough surf especially along east-facing and north-facing shores into Monday, so use caution of being near or in the water there. With the evolution of these low pressure waves as they are, things are moving right along and a cold front I once expected to arrive late Tuesday will now be offshore by midday Tuesday. “Cold front” is only used in a sense, because it will actually be warmer behind that front, as the air mass will be of continental origin, and not modified by our ocean nearby but by sun-heated land that the air mass has been passing over. So once that front goes by, we’ll have a return to more of the feel of summer through midweek, but without the humidity spiking too much. By Thursday, a very weak frontal boundary will be in the region, likely dissipating, and will probably result in more decorative clouds in the late summer sky than anything shower threat, which will be minimal as it looks right now.

MONDAY: Mostly cloudy. Risk of rain far eastern MA favoring Cape Cod early. Isolated light showers possible anywhere late morning through afternoon. Highs 70-77. Dew point lower to middle 60s. Wind NE to N 10-20 MPH coast and 5-15 MPH inland morning, variable up to 10 MPH midday, S up to 10 MPH mid afternoon on.

DAYS 6-10 (AUGUST 21-25)

High pressure brings dry weather and low to moderate humidity August 21. Higher humidity and showers/thunderstorms possible for the August 22-23 weekend, and a frontal boundary hanging nearby may keep some showers around into August 24 before high pressure builds in and returns fair weather to the region at the end of the period.

Discussion…

Our weather here in southeastern New England this weekend and Monday will be influenced by high pressure to the north and a couple waves of low pressure moving to the east and passing south of the region, the first of which has become our latest tropical system of the season, Tropical Storm Kyle, which is destined to pass harmlessly southeast of the region. The second wave of low pressure will not develop into a tropical system and while passing by a little closer than the first one, it will still be too far south to bring any appreciable rainfall to the region, with mainly dry weather being dominant. The most significant impacts of this synoptic set-up will be cooler weather, lower humidity (though not too dry), a noticeable breeze from the northeast to east, and some fairly rough surf along the shoreline, especially east-facing coastal areas, where boating, surfing, and swimming should be done with extreme caution. It won’t be the greatest beach weekend by typical standards anyway. Looking a bit ahead, this pattern lets go by Tuesday when a weak cold front crosses the region during the morning and midday with a threat of a shower or thunderstorm and a shot of muggy air. This front moves offshore during the day and drier air arrives. By Wednesday, that front is dissipating offshore while high pressure builds in with nice mid August summer weather.
