Final Days Of Summer

7:30AM

The last 7 days of Summer before the Autumnal Equinox (next Monday after 10PM) will feature a variety of weather but in a rather quiet pattern. Things look very much like described in the previous post, the small system coming through today with the shower threat, then dry and cool air mass for midweek including the reinforcing front setting up a couple very cool mornings at the end of the week, but high pressure also bringing nice weather for the end of the week and most of, if not all of, the weekend, which will feature a warm up after a chilly start. The next front will be due on Monday with a shower threat.

SOUTHEASTERN NEW ENGLAND FORECAST…

TODAY: Mostly cloudy with episodes of scattered showers ending west to east during the afternoon with clearing starting from the west late day. Highs in the 60s. Wind S up to 10 MPH.

TONIGHT: Clearing trend continues eastward. Lows in the 40s to around 50. Wind W up to 10 MPH.

WEDNESDAY: Mostly sunny. Highs in the 60s. Wind NW 5-15 MPH becoming variable late.

THURSDAY: Partly cloudy. Low 44. High 66.

FRIDAY: Mostly sunny. Low 40. High 65.

SATURDAY: Mostly sunny. Low 38. High 70.

SUNDAY: Partly cloudy. Low 50. High 78.

MONDAY: Mostly cloudy. Chance of showers. Low 55. High 72.

The Week Ahead

6:28PM

After a fairly decent weekend other than a period of rain late Saturday, it’s time to look ahead to the coming week.

This week will feature a mini warm up to start, a brief showery episode, a cool interlude, and then a more substantial warm up to end.

High pressure will hang out and give a nice day Monday, less breezy and a little milder than Sunday was. Clouds will roll in Monday night ahead of a fairly fast moving and small low pressure and frontal system from the west, which will bring a chance of showers the first part of Tuesday before it departs, and allows a cooler and dry air mass into the region Tuesday night through Thursday. In fact a second cold front will reinforce the cool air Wednesday night and Thursday. High pressure that slides in from the northwest will park itself over New England then elongate as we head into the end of the week. As upper level high pressure also tries to build over the East Coast a warm up will result. By the end of next weekend there should be low pressure in the Great Lakes which will probably send an increasing southwesterly wind into the region with even more warm air arriving as the final hours of Summer are rolling by.

SOUTHEASTERN NEW ENGLAND FORECAST…

TONIGHT: Partly cloudy to mostly clear – high clouds exit early. Lows upper 30s deep valleys far inland with patchy frost possible, 40s elsewhere except around 50 urban areas. Light north wind dropping off to calm.

MONDAY: Mostly sunny to partly cloudy – high clouds arrive late. Highs upper 60s to around 70.  Wind light variable.

MONDAY NIGHT: Increasing clouds. Showers around by dawn. Lows in the 50s. Wind S under 10 MPH.

TUESDAY: Mostly cloudy with showers in the morning. Sun returns west to east during the afternoon. Highs middle to upper 60s. Wind S 5-15 MPH shifting to W.

WEDNESDAY: Mostly sunny. Low 47. High 66.

THURSDAY: Partly cloudy. Low 43. High 61.

FRIDAY: Mostly sunny. Low 37. High 68.

SATURDAY: Partly cloudy. Low 44. High 73.

SUNDAY: Partly sunny. Low 55. High 77.

Weekend Update

10:04AM

A double-barrel weak system comes through today and tonight with clouds and limited rainfall. The bulk of rain from the southern system will remain offshore though some is still possible this evening over  RI and southeastern MA, especially Cape Cod / Islands. The northern part of the system will send a band or 2 of weakening showers/light rain eastward across the remainder of the region and not all that much rain will fall. The bulk of it will be between 6PM and 9PM, bulk being a relative term. Overnight it’s all departing. Sunday, a cool northwesterly flow takes over with plenty of sun and the feel of Fall (even though it’s still technically Summer). High pressure hangs on for Monday with more sun and a little bit of a warm-up. A weak and fast moving system will bring wet weather to the region the first half of Tuesday before it gets out of the way for another cool high pressure area Tuesday night and Wednesday. This high will park itself over the region during midweek then start to settle southward. This will begin a transition toward a warmer pattern again.

SOUTHEASTERN NEW ENGLAND FORECAST…

THROUGH MIDDAY: Most sun from the I-95 corridor southeastward, less northwest. Temperatures climb into the 60s. Wind E 5-15 MPH.

MID AFTERNOON TO SUNSET: Clouds win out, some light rain or showers arriving especially north and west of Boston, then some rain possible RI to Cape Cod late day. Highs 65-72. Wind E 5-15 MPH.

TONIGHT: Mostly cloudy start, showers/rain ending west to east. Clearing overnight. Lows 48-55. Wind variable 5-15 MPH shifting to NW.

SUNDAY: Sunny to partly cloudy. Highs 65-70. Wind NW 10-20 MPH.

MONDAY: Mostly sunny. Low 45. High 70.

TUESDAY: Cloudy with showers through early afternoon then clearing west to east. Low 50. High 66.

WEDNESDAY: Mostly sunny. Low 43. High 66.

THURSDAY: Partly sunny. Low 47. High 69.

FRIDAY: Mostly sunny. Low 49. High 72.

Some Small Systems

5:20PM

3 small systems will impact the weather in southeastern New England during the next 7 days, one this evening, one Saturday evening, and one early Tuesday, based on current timing.

The first one is a cold front passing by this evening but with limited shower activity, however still serving to push some muggy air out of the region and replace it with cooler and drier air by Friday into Saturday.

The second system will be a weak double barrel low pressure area passing by Saturday night from southwest to northeast. The first low will move through the eastern Great Lakes and keep most of its moisture north and west of here. The other low will move out south of New England and it currently looks like the greatest chance of wet weather from that will be occurring over RI and southeastern MA. All of this will be offshore by Sunday which will be another cooler, dry day, with this weather lasting through most of Monday as well, though with a bit of a warm-up later Monday.

The third system looks like a weak low pressure area moving through early Tuesday of next week with a shower threat and another shot of cooler and drier air following it.

SOUTHEASTERN NEW ENGLAND FORECAST…

THROUGH EVENING: Mostly cloudy. Scattered showers. Humid. Temperatures falling slowly through the 70s. Wind SW 10-20 MPH with higher gusts.

Patience In Blog & Weather

3:25PM

A quick note to all the readers here, whether you are just a lurker or a regular comment contributor: As you can tell I’ve been trying out several different blog styles. These are provided by WordPress, and are limited. I am likely to get some others in the next few days so the trials will go on for a while. Please have patience while I see what works best for all. It’s possible that we end up back on the old boring set-up as well. But I think giving the different styles a try is worth it first!

As for the weather, the humidity is coming back, or is actually back now, just not as noticeable as it was on a light easterly wind and with limited sunshine Wednesday with areas of low cloudiness from the ocean. But the wind will turn southerly ahead of a cold front tonight and Thursday and you’ll feel the humidity more, especially as it warms up Thursday with lots of clouds and some limited sun. The front will slice through the region Thursday night, with showers and thunderstorms, then clear the coast on Friday, which will end up a bright and drier day. The weekend should be mostly decent, but a weak system coming along from the west late Saturday to first thing Sunday will cause an interruption to the nice weather with lots of clouds and some risk of showers. Fair and pleasant weather returning for the end of the weekend will continue Monday. Another weak system may be in the vicinity early Tuesday of next week with another shot of dry air following this.

FORECAST FOR SOUTHEASTERN NEW ENGLAND…

THROUGH SUNSET: Lots of clouds but dissipating again somewhat to allow more sun before it goes down. Temperatures around 70. Wind light E.

TONIGHT: Partly to mostly cloudy. Lows around 60. Wind light E shifting to S.

THURSDAY: Mostly cloudy to partly sunny. Highs from 70 South Coast and Cape Cod to 75-80 interior areas. Wind S 10-20 MPH.

THURSDAY NIGHT: Mostly cloudy. Showers and thunderstorms pushing west to east across the region, ending by dawn, arriving and ending latest on Cape Cod. Lows in the 60s. Wind S to SW 10-20 MPH with higher gusts.

FRIDAY: Partly cloudy to mostly sunny. Highs 70-75. Wind W 10-20 MPH.

SATURDAY: Sun to clouds. Few showers at night. Low 55. High 70.

SUNDAY: Clouds to sun. Few showers Cape Cod early. Low 57. High 70.

MONDAY: Partly cloudy. Low 53. High 69.

TUESDAY: AM showers, PM sun. Low 55. High 67.

WEDNESDAY: Mostly sunny. Low 47. High 66.

Edging

11:31PM

Southeastern New England will sit on the edge of a couple waves of low pressure through Wednesday, close enough for some cloudiness but rain should remain mostly offshore. The air flow between low pressure to the south and high pressure to the north will be easterly, and may bring in enough low level moisture for some low clouds and perhaps some drizzle for a time Tuesday night or early Wednesday. By Thursday, we’ll get rid of those lows and be in a southerly flow ahead of an approaching cold front. Current timing suggests this front will come through early Friday with a threat of showers, then introduce a drier and cool air mass for the weekend followed by a slight warm-up heading into early next week.

Astronomically high tides associated with the Full Harvest Moon may be enhanced by the easterly flow through Tuesday night, resulting in some minor coastal flooding in areas prone to it.

SOUTHEASTERN NEW ENGLAND FORECAST…

OVERNIGHT: Some clouds. Lows in the 50s. Wind light E.

TUESDAY: Partly sunny. Highs upper 60s coast to middle 70s well inland. Wind light E.

TUESDAY NIGHT: Mostly cloudy. Patchy coastal drizzle late. Lows in the 50s. Wind light NE.

WEDNESDAY: Mostly cloudy to partly sunny. Patchy drizzle early. Highs middle 60s coast to lower 70s inland. Wind NE 5-15 MPH.

THURSDAY: Partly sunny. Chance of showers/thunderstorms at night. Low 56. High 76.

FRIDAY: Partly cloudy. Chance of showers eastern areas early. Low 55. High 69.

SATURDAY: Partly cloudy. Low 45. High 65.

SUNDAY: Mostly sunny. Low 43. High 67.

MONDAY: Partly cloudy. Low 48. High 69.

The Week Ahead

3:45PM

The September heat is gone, though the overall pattern is still mild to warm. However, compared to last week, this coming week will feel much more pleasant. It starts wonderfully with high pressure centered north of the region Monday, delivering pleasant air on a northeast wind that has not spent much time passing over water, but rather eastern Canada, so it will be on the dry side. This high retreats a little bit Tuesday and Wednesday as a smaller low pressure area to the south tries to push to the north. Expect increasing cloudiness Monday night and Tuesday, decreasing by later Wednesday. The question is, does any rain from the low make it into the area. For now, the thinking is that there is a risk of some in southern sections, but probably not very much. A warm-up is slated  for the end of the week and a series of cold fronts will then try to push in from the west, bringing some risk of showers, especially Thursday. Next weekend looks dry and pleasant at this time as high pressure should be moving into the region. One caution is that we may need to watch the last of the fronts moving offshore in case it slows down.

SOUTHEASTERN NEW ENGLAND FORECAST…

TONIGHT: Clear. Lows in the 50s most areas, some upper 40s interior valleys. Wind light N.

MONDAY: Sunny but some high clouds moving in late. Highs 68-74, coolest East Coast. Wind NE 5-15 MPH.

MONDAY NIGHT: Increasing clouds. Lows in the 50s. Wind light NE to E.

TUESDAY: Mostly cloudy. Chance of light rain South Coast. Highs 66-73, coolest South Coast. Wind E 5-15 MPH.

WEDNESDAY: Decreasing clouds, increasing sun. Low 52. High 71.

THURSDAY: Partly sunny. Chance of showers. Low 56. High 78.

FRIDAY: Partly cloudy. Chance of showers. Low 58. High 79.

SATURDAY: Partly cloudy. Low 56. High 72.

SUNDAY: Mostly sunny. Low 50. High 70.

A Sliced Weekend

3:34PM

9:27AM Saturday morning edit to remove the Friday night forecast portion.

Heat and humidity came back in on Friday with sunshine & a few clouds, along with that hazy look that we did not see a whole lot of during the middle of the Summer. This air mass will continue to be with us in southeastern New England into Saturday, but will be pushed out of here by a cold front that crosses the region from northwest to southeast Saturday afternoon and evening, accompanied by showers and thunderstorms. With this front cutting into the very warm and muggy air mass, and sufficient instability, some of the storms may be strong to severe.  There will also be areas that escape the worst of this and end up with very little action with the front. Once this front clears the region overnight, it will set up a couple very nice days Sunday and Monday. Toward Tuesday and the middle of next week, the weather may go downhill as an area of low pressure forming along the stalled front once its to our south will try to toss clouds and some wet weather back into this area.

FORECAST FOR SOUTHEASTERN NEW ENGLAND…

SATURDAY: Partly sunny and hazy. Heavier clouds with a risk of showers and thunderstorms northwest to southeast mid afternoon through early evening. Any storms may be strong to severe. Muggy. Highs in the 80s, may hit 90 in a few locations, some upper 70s South Coast / Cape Cod. Wind SW 10-20 MPH with higher gusts.

SATURDAY NIGHT: Variably cloudy with a good chance of showers and thunderstorms early, but ending northwest to southeast. Drying late. Lows around 60. Wind W 5-15 MPH.

SUNDAY: Partly cloudy. Highs in the 70s. Wind NW 10-20 MPH.

MONDAY: Mostly sunny. Low 53. High 73.

TUESDAY: Increasing clouds. Low 54. High 72.

WEDNESDAY: Mostly cloudy. Chance of rain. Low 56. High 75.

THURSDAY: Variably cloudy. Low 55. High 73.

FRIDAY: Mostly cloudy. Chance of rain. Low 55. High 70.
