Thunderstorms made a run for eastern MA on Wednesday night but ran into issues, specifically some warm air above the ground which capped the atmosphere, and in addition to forcing the storms to die out as they moved closer, kept any from forming in the area during the day. A few downpours and storms did regenerate and move across northeastern MA and southeastern NH, but all the activity is now gone. A second disturbance may send a cluster of showers/storms across northern MA and southern NH during the early morning, but no severe weather is expected. During the day Thursday, sunshine will end up dominant as cloudiness from the first batch of storms is offshore and afternoon storms will be only isolated. The main action, in the form of a line or cluster of showers and thunderstorms, will arrive during the later evening or night, and may hold off in much of eastern MA and RI until after 11PM. This will lessen the chance of any severe weather, which will be much less likely well after the maximum daytime heating. Nevertheless, the atmosphere over eastern MA, southern NH, and RI, will be far less stable than it was during Wednesday, so storms are a good bet.

The cold front responsible for the storm threat will be very slow to exit on Friday, and a wave of low pressure forming on it along with upper level low pressure moving in from the west will combine to cause additional showers and possible thunderstorms during the day – a slightly more pessimistic forecast than previous. By Friday  night, genuinely drier and much cooler air will finally make it to the region, setting us up for another feel-of-fall day on Saturday, as surface high pressure builds in. Another quick turn-around day will occur Sunday as high pressure sinks to the south and the air warms (but not nearly to the levels of the current spell of heat). Another cold front flies across the region early Monday, sending another chilly air mass in for the early part of next week. Temperature moderation will follow by the middle of next week as the roller-coaster pattern continues.

Updated forecast for southeastern New England (southern NH, eastern MA, and RI)…

First I would like to re-post a portion of a comment I made on the previous blog…

Media (news directors want this) puts out forecasts of a cold & possibly snowy winter ahead, as do two of the more popular almanacs. And my scientific view point is skewed today by a reliable long range model forecasting warmer than normal weather overall (not every day) for the balance of 2013, right into the winter. Conflicting indications much? Based on that, and common sense, I won’t be issuing an “official” winter forecast until around the middle of November. Call me a coward, but I’m playing it safe. I just have no idea what the upcoming winter will be like. I prefer to focus on the next 7 days, detailing as much as I can the next few days, and generalizing days 4 to 7. This will continue to be a daily practice and I hope you find it useful.
Now, on to that practice…

Lots of clouds and a period of rain visited much of southeastern New England today, and now a warm front has cleared the region, leaving behind only some lingering cloudiness. But the door has been opened to an air mass more typical of the middle of Summer, and Wednesday will evoke a memory of  the heat in July that was prevalent for much of the month. But how you can tell this is a late Summer heat blast will be by observing that the sun does not rise so early as it did back in July, and of course that it sets much earlier (7PM versus about 8:20PM) and in a more due west direction instead of the northwest as it did in the longest days. In fact Wednesday’s sunset is the final 7PM or later sunset for the year.

A heat advisory has been posted for Wednesday for most of eastern MA except the South Coast through Cape Cod, and for interior southeastern NH. High temperatures in these areas will be in the lower to middle 90s, and the heat index (how it feels combining heat & humidity) will reach or exceed 100.

With the cold front that will put an end to this heat still located far to the northwest of the area, Wednesday night will be a very warm and humid night, uncomfortable for sleeping for some of you. This is why it’s not always a wise idea to take out and pack up the AC before the end of September.

The cold front may be slow enough that we get through the daylight hours of Thursday with no more than the threat of an isolated shower or thunderstorm, and a main line of showers and storms holding off until sometime at night, possibly late at night. At this time, I am going to go with the main action not reaching the region until after the Pats/Jets game, but anybody going to the game should be prepared for stormy weather, in case it does arrive more quickly than currently expected.

Once the cold front gets into the region it will push sluggishly through during the overnight of Thursday and early Friday morning, with its showers and storms finally pushing to the South Coast and Cape Cod. Lingering rain is expected over eastern MA for a portion of Friday morning as a little wave of low pressure forms on the front just gone by, but it may be somewhat unstable during the afternoon as colder air moves in aloft and sets the stage for additional pop up showers in the afternoon to early evening. It will be turning breezy and much cooler with the air drying out. By Friday night and Saturday, the core of this much cooler air mass will be over southeastern New England, and it will feel more like late September or early October.

Looking ahead: A great finish to the weekend, bright and a little milder by Sunday. A reinforcing cold front comes through Sunday night or early Monday, bringing another shot of chilly air to the region for a brief stand before a new warm-up commences.

A week of changes, especially temperature changes, is what we have coming for southeastern New England. A refreshing air mass moved in during Sunday and will be right over the region Monday, starting the new work and school week off on a bright, dry, cool note. But the high pressure area responsible for this shot of cooler air will sink to the south of the region on Tuesday and a very rapid warm-up will ensue, accompanied by some cloudiness Tuesday as the warm air flows in both at the surface and aloft. By Wednesday, enough of the long-lasting heat from the Plains will have been tapped and transported northeastward to bring a burst of mid Summer heat to the region. Very warm air will hold on into Thursday, along with a shot of humidity ahead of an approaching cold front. This front will bring showers and thunderstorms sometime between Thursday afternoon and Thursday night, timing uncertain and based on the timing of the front which will become more clear as that time frame moves closer. The end of the week looks much cooler, but the amounts of fair weather versus a shower threat will depend on the position and movement of an upper level low pressure trough. The Friday through Sunday forecast is very low confidence at this point so please check back for updates.

School’s back in session and September is nearly a week old. For many, this is Fall, but we all know that technically we are pushing through the late Summer with the equinox still many days away. The pattern will be one of mostly dry weather and roller-coaster temperatures (cool today, warmer  weekend, cooler early  next week, warmer mid next week). The only precipitation threat comes during the morning hours of Sunday as a disturbance passes through the region then perhaps at the very end of the forecast period which is too far away to figure out any detail.

Updated forecast for southeastern New England (southern NH, eastern MA, and RI)…

7:20AM

Weather systems are moving along, but the pattern will be quiet since none of these systems are likely to cause any significant weather. One such weak system is moving through this morning with clouds and a few brief showers, but is really just the leading edge of a shot of cooler air which will be with us through Friday night. High pressure that builds in Friday will quickly sink to the south of New England Saturday, allowing a warm-up. By Sunday another weak cold front will slide through, probably early in the day, without a great deal of fanfare, and return a slightly cooler air mass to the region for early next week. Quickly on its heels a warm up follows by the middle of next week.

11:30PM

The cold front is through the region and drier air is now flowing in, and will be in place for a few days. It will still be a warm day Wednesday as high pressure builds in. A secondary cold front will pass through the region Thursday bringing clouds and a risk of passing showers, introducing a cooler and dry air mass that will last through Friday night. Temperatures will moderate on the weekend as high pressure sinks south of the region. Another cold front will approach on Sunday bringing some clouds and possibly a few showers, before a push of somewhat cooler air arrives for the start of next week.

5:34PM

No sense going into great detail about Monday, since it’ll be mainly over by the time most of you read this. You either saw some downpours or you did not. All in all, it was not a total wash out of a day in just about all areas but a few areas did see more persistent shower and storm activity, with localized flooding being the main issue where storms lasted. Are we in for a repeat tomorrow? Yes and no. Though there will be muggy air remaining around tonight through much of tomorrow and showers/storms can pop up at any time, some producing heavy rain, I think we really only have a 3 hour period Tuesday across southeastern New England in which the heaviest and most widespread activity will occur. This is about 11AM to about 2PM for southern NH, east central and northeastern MA, and after 2PM until about sunset for southeastern MA and RI. Once the front interacting with the muggy air pushes to the east and offshore (later Tuesday night), we will see some drier air work in and fair weather which will last through Wednesday. Another cold front will swing across the region from northwest to southeast Thursday, producing clouds and perhaps some passing showers, and introducing a cooler air mass for Thursday night through Friday night, with fair weather. High pressure settling to the south of New England will quickly cause a warm-up over the weekend, and we’ll have to watch another cold front trying to push in from the northwest on Sunday (based on current timing expectations).

Updated forecast for southeastern New England (southern NH, eastern MA, and RI)…

TONIGHT: Mostly cloudy. Scattered showers and a few thunderstorms with local downpours. Areas of fog. Muggy. Lows in the 60s. Wind SW under 10 MPH.

3:20PM

For the next 5 to 7 days we will be stuck in a pattern of humid southwesterly flow between high pressure over the Atlantic Ocean and a mean low pressure trough to the west of New England. Weak frontal systems will try to push through from time to time, responsible for kicking off episodes of showers and thunderstorms, but none of these fronts will make a strong push through the region. I don’t see a big change in this pattern right into the middle of next week. The news here is mixed, since many people have outdoor plans for the long weekend, showers in that case are not so welcomed. But it has been dry in August, so any rain in that regard is welcomed. I believe that most of the shower activity will be north and west of Boston through Sunday and more likely anywhere in the region Monday. By Tuesday it should back off somewhat but the threat will still be there. It remains to be seen how much dry air works in by the middle of next week. I’m leaning away from it making a strong push into the region, at least initially.

Updated forecast for southeastern New England (southern NH, eastern MA, and RI)…

THROUGH SUNSET: Mostly sunny to partly cloudy with only a slight risk of an isolated shower. Temperatures ranging from near 70 immediate coast to near 80 inland locations. Wind SW 5-15 MPH.

8:55PM

In the short term (tonight), a disturbance moving southward from Maine and eastern NH has fired off some showers and thunderstorms and they will be advancing southward into southeastern NH and northeastern MA. I expect them to weaken, but one or 2 cells may hold together enough to produce local downpours and some lightning/thunder. Something to watch out for. Not expecting any severe weather if storms due hold together.

Broad but weak low pressure offshore of southern New England brought cooler air to eastern coastal areas along with some fog and low clouds during Wednesday, and this will expand as low clouds push inland and fog envelops much of coastal NH, eastern MA, and southeastern RI overnight into Thursday. The marine air should prevent showers from forming though there will be some in the warmer air located far west and north of southeastern New England. By Friday, the low pressure area will be far enough offshore so that high pressure building in will develop a land breeze over most of the region and warmer air will arrive on Friday. This should last into Saturday though a few spot showers cannot be ruled out as a disturbance slides through from the northwest. The remainder of the Labor Day weekend will see a slightly increasing risk of showers and a few thunderstorms but no wash-outs are expected. Despite the warm-up on Friday, there is no significant heat in sight through the weekend.

Forecast for southeastern New England (southeastern NH, eastern MA, and RI)…

TONIGHT: Fog spreads and thickens across coastal NH, east coastal MA, southeastern MA, and southern and eastern RI. Otherwise mostly cloudy with isolated showers mainly in southeastern NH and northeastern MA early then dissipating. Lows 59-65. Wind NE to E 5-15 MPH.

THURSDAY: Cloudy coastal areas, mostly cloudy inland. Foggy areas remain, especially near the coast. Highs 65-70 immediate coast, 70-75 inland. Wind NE 5-15 MPH.

FRIDAY: Partly to mostly sunny. Highs 80-85 except 70s some coastal areas. Wind SE shifting to SW 5-15 MPH.

SATURDAY: Partly cloudy. Slight chance of PM showers inland. Low 60. High 80.

SUNDAY: Partly sunny. Isolated showers/thunderstorms. Low 62. High 80.

MONDAY – LABOR DAY: Variably cloudy. Scattered showers/thunderstorms. Low 63. High 77.

TUESDAY: Partly sunny. Isolated showers/thunderstorms. Low 63. High 81.

WEDNESDAY: Mostly sunny. Low 61. High 83.

2:32AM

Broad but weak low pressure sitting just offshore during the next 2 days will add clouds and a shower threat to the weather in southern New England before pulling offshore and allowing high pressure to bring nicer late Summer weather by Friday and much of the Labor Day Weekend, though the next trough from the west is expected to bring a shower and thunderstorm threat by the holiday itself, and delay the onset of a shot of  heat from the Midwest/Plains heatwave. Still looking for some of this to eventually get to the eastern US though it may take a while.

Updated forecast for southeastern New England…

TODAY THROUGH THURSDAY: Variably cloudy with a few episodes of showers and possibly a few thunderstorms. Highs around 80 except cooler coast. Lows around 60. Somewhat humid. Winds primarily E to N 5-15 MPH.

8 days a week! It’s bonus time! An 8 day forecast? Say it ain’t so! Just once in a while, and this time it’s because next weekend is Labor Day Weekend. So let’s attempt to simply explain how weather systems should behave during this time and then forecast the expected resultant weather.

A strong ridge of high pressure will reside in the central USA for much of this week. A 2-part disturbance that came over the top of this ridge will fly across southern New England from northwest to southeast today bringing a couple shower threats and possibly a thunderstorm to a few areas, but much of the region will be rain-free much of the time. Another disturbance is set to arrive on Wednesday and its associated front will hang along the South Coast and be the focus for another wave of low pressure that may prolong unsettled weather into Thursday. By Friday, all of this should be on its way out and a shot of drier air will arrive, resulting in very nice weather into the holiday weekend. The deeper into the weekend we go, we will see the heat from the middle of the country starting to nose its way toward New England with the feel of Summer once again becoming prominent.

Forecast for southeastern New England (southern NH, eastern MA, and RI)…

TODAY: Mostly cloudy morning with weakening area of showers from northwest to southeast across the region then lots of clouds but partial sun and isolated showers or thunderstorms in the afternoon.

MONDAY – LABOR DAY: Partly cloudy. Low 66. High 88.

9:31AM

High pressure remains in control today with another beautiful day capping off a great weather weekend of low humidity, mild air and some cooling sea breezes near the coast.

An unsettled period of weather is expected Monday through Thursday as we’ll be near the boundary of the refreshing air and the northeastern corner of a big central US heat wave.

Nicer weather is expected to return Friday and on into the start of the Labor Day Weekend before the heat in the Midwest starts to shift into the eastern US.

More details on all of this posted this evening in a special extra extended forecast for next week including the entirety of the Labor Day Weekend.

For now, a quick update to the forecast for southeastern New England…

TODAY: Sunny. Highs 75-83, coolest coast. Wind variable, mainly N, 5-15 MPH, but coastal sea breezes as well.

7:34AM

One more very warm to hot day today ahead of a cold front. A disturbance ahead of this front may kick off a few showers or thunderstorms mainly in southern areas this afternoon, and the cold front itself may do the same in any area tonight into Friday. Cooler and drier air flows in for Friday night into the weekend. It warms up a little early next week but being near a frontal boundary next week means that it may be more unsettled.

Who said the heat was done weeks ago? Not I. Climatology says that you do NOT count out hot days at that point in the season. While it’s true we slipped into a cool pattern for the end of July and the first half of August, for the time being we are out of that pattern and the peak of the warm side of the new pattern will take place during the next 2 days as a high pressure ridge dominates the weather across southern New England. No not everybody will reach 90 Wednesday & Thursday, but we will see a few 90+ readings around the area. A cold front will put an end to that as it slides across the region Thursday night, bringing cooler air in for Friday and the weekend. A back-side warmup is expected for next Monday before we slip into a back-and-forth regime as we head down the home stretch of August next week.
