An anomalous pool of cold air almost literally put Winter above Summer Thursday, as the air which was only a little cooler than normal for much of the day at ground level was much colder than average aloft. This made the atmosphere unstable and allowed showers and thunderstorms to pop up. The lack of haze allowed for great visibility and viewing of storms which included spectacular cloud formations, heavy downpours, lightning, and hail. Not every place saw these conditions, yet some saw them more than once. It all depended on where you were in relation to the storms.

Now to look ahead. The chilly pool of air will be moving away to the east but its western edge still still be over eastern MA and NH on Friday, allowing additional clouds to pop up with another risk of showers and thunderstorms. Activity will not be as widespread as it was Thursday.

The weekend: High pressure dominates with fantastic Summer weather – low to moderate humidity, lots of sun, mild to warm air.

Early  next week: High pressure starts to slip offshore allowing warmth and humidity to increase.

Middle next week: Frontal system and another advancing trough brings a chance of showers and thunderstorms with a cooling trend.

As talked about in the previous blog, a trough of low pressure will slowly traverse the Northeast this week, with somewhat unsettled weather as we transition from warmer and slightly more humid air Tuesday into Wednesday to cooler and a drying trend later in the week. The only change is going to be to add a chance of a few lingering showers to Friday’s forecast. The weekend still looks great! An offshore frontal system will help steer Tropical Storm Bertha to the north then northeast between the East Coast and Bermuda, with the only impact being some increased ocean swells and rip currents later in the week at the beaches.

Well here we are at the end of the first weekend of August. Summer’s rolling along and whether you like heat or not, I bet you are wondering why we haven’t had any prolonged spells of heat. It’s just not the pattern this year. The various atmospheric indices have combined and conspired to produce a southward-displaced jet stream and frequent troughs dropping from Canada into the Upper Midwest, Great Lakes, or Northeast. This has kept heat in check. This same general pattern will continue into the middle of August. But pulling back a bit it’s time to look at the upcoming 7 days for the weather systems and resultant weather during this time.

We’ll continue to have that old frontal boundary sitting offshore early in the week, and a broad but weak trough of low pressure traversing the Northeast from west to east. It will take 4 days (through Thursday) to do this, so there will be daily opportunities for showers and thunderstorms, though it certainly will not rain much of the time, and some nice weather will also take place. By the time we get to Friday, the trough should be exiting to the east and a push of dry, cooler air will arrive. This sets up what looks at this time to be a great weekend as high pressure dominates. Again there is no major heat in sight.

Also, Tropical Storm Bertha will be taking a track between the US East Coast and Bermuda, passing well southeast of New England about midweek. The only impact will be some increased surf and rip current risks later in the week.

Forecast for southeastern New England…

TONIGHT: Variably cloudy. Patchy fog.Lows upper 50s to middle 60s. Wind light variable.

MONDAY: Partly sunny. Isolated showers possible morning-midday. Isolated to scattered showers and thunderstorms possible mid to late afternoon. Highs 72-79 South Coast, southeastern MA, and East Coast beaches, 79-85 elsewhere. Wind mostly SE to S up to 10 MPH.

MONDAY NIGHT: Partly cloudy. Patchy valley fog. Lows 60-66. Wind light S.

TUESDAY: Partly cloudy. Isolated to scattered showers and thunderstorms possible mid to late afternoon. Highs 70s Cape Cod and coastal areas, 80-85 elsewhere. Wind S 5-15 MPH.

WEDNESDAY: Variably cloudy. Scattered to general showers/thunderstorms especially late. Low 65. High 80.

THURSDAY: Partly cloudy. Pop up afternoon showers. Low 60. High 80.

FRIDAY: Partly cloudy. Low 57. High 78.

SATURDAY: Mostly sunny. Low 55. High 80.

SUNDAY: Mostly sunny. Low 60. High 82.

Brief update for now with a full discussion to be posted this evening with The Week Ahead.

Minor change for today – more showers further northwestern than expected, so a little on the wet side this morning, and less so this afternoon.

Approaching trough from the west and still a weakness in the pressure field along the coast will keep the risk of unsettled weather going for much of the coming week through Thursday, but shower activity will just be isolated to scattered with no long-lasting rain. Tropical Storm Bertha will move from the north central Caribbean into the eastern Bahamas today, then curve north to northeast between Bermuda and the US East Coast by the middle of the coming week. This path will keep the wind/rain from the storm well offshore but may increase surf and rip currents at the beaches by later in the week.

Low pressure trough may be slow to leave so some clouds and a shower may hang around even on Friday. High pressure should arrive by the start of next weekend with some nice weather!

Forecast for southeastern New England…

TODAY: Limited sun – lots of clouds. Episodes of showers, possible in any areas this morning but favoring southeastern areas overall through the day. Highs in the 70s. Wind E up to 10 MPH.

TONIGHT: Mostly cloudy. Lows in the 60s. Wind light SE.

MONDAY: Partly sunny. Scattered showers and thunderstorms mainly in the afternoon. Highs middle 70s to lower 80s, coolest in coastal areas. Wind SE to S 5-15 MPH.

TUESDAY: Partly cloudy. Slight chance of showers. Low 61. High 83.

WEDNESDAY: Partly sunny. Scattered showers/thunderstorms. Low 64. High 80.

THURSDAY: Variably cloudy. Chance of showers. Low 64. High 81.

FRIDAY: Partly sunny. Slight chance of showers. Low 58. High 80.

SATURDAY: Mostly sunny. Low 60. High 83.

9:47AM

A frontal system will be just offshore through the weekend and it looks like it will remain east of southeastern New England, keeping this area on the cloudier, cooler side. We’ll also be dealing with areas of rain sliding up along the front, most notably today, which will be the wettest day, coverage-wise, with rain for a good portion of RI, eastern MA, and southern NH to some extent, into the afternoon before the area pushes back to the east and out of the region. Clouds may even break late in the day with a few areas possibly (no promises) seeing some sun before it sets. With temperature and dew point hanging out around each other tonight, we cannot rule out areas of fog forming. It looks like clouds will be the rule Sunday but most of the rain should stay offshore, with another patchy area possibly forming but staying to the west of the region. This should leave southeastern New England in between with just a slight risk of showers.

The front that sits just to the east during the weekend likely dissipates by Monday as a  new trough from the west pushes into the region, but takes 4 days to pass by. What does this mean? It means humid, but not hot, and a daily risk of showers and thunderstorms Monday through Thursday. Details and timing will be worked out as each day moves closer.

Updated forecast for southeastern New England…

TODAY: Cloudy through early afternoon with rain ranging from steadiest and moderate at times in southeastern MA and RI to lighter and more occasional further north and west. Decreasing rain from west to east mid afternoon with all areas rain-free by day’s end, lots of clouds still remaining but some breaking clouds with even some sun possible later on. Highs in the 70s. Wind variable to mostly E up to 10 MPH.

TONIGHT: Mostly cloudy. Patchy fog. Lows in the 60s. Wind light variable.

SUNDAY: Mostly cloudy. Slight chance of showers. Highs in the 70s. Wind E 5-10 MPH.

MONDAY THROUGH THURSDAY: Variably cloudy. Daily risk of showers/t-storms. Overnight lows mainly 60s. Daytime highs middle 70s to middle 80s, coolest Cape Cod.

FRIDAY: Sunny. Low around 60. High around 80.

2:17AM

The next 2 days we will be under the influence of a very weak high pressure area but still in between a frontal boundary and another trough of low pressure to the west. The energy from the west will be enough to set off a round or 2 of pop up showers and possible thunderstorms each of the next 2 afternoons (today and Friday). Most areas will not see anything as coverage will be isolated to scattered, but anywhere that does see something could experience a downpour. The greatest threat for these pop ups will be along and northwest of a line from Providence RI to Boston MA.

By Saturday, the offshore frontal boundary will back up toward the coast, likely increasing the cloudiness over the region. The wildcard is how much rain gets involved, and there will be the chance of areas of rain, but at this stage my guess is that the greatest chance for this rain will be over Cape Cod and southeastern MA and less so elsewhere. Sunday, the boundary, though weak, will likely push further northwestward into the region, and it should be a muggy day with lots of clouds, some sun, and occasional showers and thunderstorms. This may linger into Monday as the front washes out over eastern New England. By Tuesday into midweek, weak high pressure should return and bring fair weather.

Forecast for southeastern New England…

TODAY: Partly cloudy. Isolated to scattered showers and thunderstorms in the afternoon, especially inland areas. Highs 74-82, coolest South Coast. Wind SW 10-20 MPH.

TONIGHT: Partly cloudy. Patchy fog. Lows in the 60s. Wind SSW 5-15 MPH.

FRIDAY: Partly sunny. Isolated to scattered showers and thunderstorms in the afternoon, again mainly inland. Highs 75-83, coolest South Coast. Wind S 5-15 MPH.

SATURDAY: Mostly cloudy. Chance of rain at times, especially southeastern MA. Low 64. High 78.

SUNDAY: Variably cloudy. Episodes of showers/thunderstorms. Low 68. High 82.

MONDAY: Partly sunny. Scattered showers/thunderstorms. Low 68. High 84.

TUESDAY: Partly cloudy. Low 64. High 81.

WEDNESDAY: Mostly sunny. Low 64. High 82.

1:21AM

As July winds down and August approaches we’ll be dealing with the same issue, and that is watching the boundary of cool air to the west associated with a Great Lakes and Midwest low pressure trough, and warmer air to the east associated with upper level high pressure. Where the boundary lies will determine the weather in southeastern New England in the days ahead. For the most part this boundary will be far enough east that the focus of any serious rain will be well offshore, and only a few pop up showers are expected daily the next few days. There are some indications that retrogression (westward movement) of the pattern will take place over the weekend with eventually a better chance of wet weather, but there is still some uncertainty. For now, going to go with some wet weather, favoring the second half, but not a wash out of a weekend.

Updated forecast for southeastern New England…

TODAY: Partly cloudy. Isolated afternoon showers, especially inland. Highs 70s to near 80, coolest coast. Wind variable around 10 MPH with sea breezes.

TONIGHT: Partly cloudy. Lows upper 50s to middle 60s. Wind light variable.

MONDAY: Partly sunny. Isolated PM showers/t-storms. Low 64. High 84, cooler coast.

TUESDAY: Partly cloudy. Low 65. High 85, cooler coast.

10:30PM

Eventful weather Monday. You know all about it by now, so we won’t spend any time going there on the discussion here, however feel free to continue to talk about it in the comments!

Now it’s time to look ahead. And first we have drier air sweeping in behind departing low pressure, that will make a very pleasant Tuesday. Narrow high pressure will hold its ground between a frontal boundary offshore in a trough to the west Wednesday through Friday with fair weather resulting, again with the lack of heat. By the weekend, we may see a squeeze-play as the front offshore tries to back westward and the trough to the west tries to push eastward, resulting in at least more cloudiness. It’s unclear this far in advance if any wet weather will become involved. High pressure may strengthen somewhat by early next week with a more typical feel of early August.

Forecast for southeastern New England…

OVERNIGHT: Variably cloudy with isolated showers mainly far NW of Boston through midnight, then clearing. Drier. Lows 55-63, coolest NW suburbs of Boston through interior southern NH. Wind W 5-15 MPH.

SUNDAY: Variably cloudy. Slight risk of showers interior MA/NH. Low 64. High 82, cooler coast.

MONDAY: Partly cloudy. Low 66. High 84, cooler South Coast.

6:41PM

This Summer’s weather could be a whole lot worse given the lack of high pressure ridging and the number of low pressure troughs coming through. We have seen temperatures not that far from normal overall, and despite some episodes of severe storms, we have not seen too much in the way of very nasty or excessively wet weather. And the coming week will be representative of the Summer up to this point – a bit of storminess, some great weather, and a lack of heat.

The stormy day will be Monday, because a low pressure area has to cut right across New England and this will bring many showers and some thunderstorms. There is a slight risk of some briefly severe storms, but widespread severe weather is unlikely as the timing of the activity will be before maximum  heating and other factors influencing severe storms and allowing them to form and sustain themselves will be mostly borderline. Nevertheless, keep an eye on current conditions during the day Monday should any severe storms develop.

The upper level trough responsible for sending Monday’s low pressure area through here is another one that is deeper than average, like the recent one, and will be hanging around the Great Lakes for a few days while slowly weakening. But dry air on the back side of the departing low Monday night will sweep into southeastern New England on Tuesday, which will be a very nice Summer day with lower humidity and mild air.

A weak area of high pressure will be over the region on Wednesday, keeping the weather fair, as the trough continues to weaken to the west and high pressure starts to build off the Atlantic Coast. This type of set-up is a fair weather one with sea breezes in coastal areas.

Later in the week expect a slow weakening of the trough to the west to continue while a slow strengthening of high pressure takes place offshore. It does not evolve into the classic summertime Bermuda High set up at this point but is enough to bring generally fair and mild to warm weather for the end of the week, though a disturbance may try to get going between these upper level systems to bring at least some cloudiness to the region by next weekend, though so far it looks largely rain-free.

Forecast for southeastern New England…

TONIGHT: Clouds push eastward across the region early then decrease for a while before increasing again from the southwest later. Showers/thunderstorms southwest of Boston before dawn. Areas of low clouds and fog forming as well. Humid. Lows in the 60s. Wind S 5-15 MPH.

10:33PM

The transition day is done, and it was a nice day for many, despite some cloudiness. Some wet weather was still hanging around parts of Cape Cod, but now it’s time for a high pressure area to build in for Friday with pleasantly dry air and mild to warm temperatures, along with lots of sun and a few clouds – a great Summer day!

The weekend will be a split decision. High pressure hangs on Saturday which will be a warm day with fair weather and a slight increase in humidity. By Sunday, a trough from the west will bring unsettled weather with more humidity as well as showers and thunderstorms. This will continue Monday as a deeper trough of low pressure digs into the Midwest and Great Lakes. The trough should start to weaken and lift northeastward into southeastern Canada toward the middle of next week with improving conditions.

OVERNIGHT: Partly cloudy to mostly clear. Lows in the 50s except lower 60s urban areas and immediate coast. Wind N up to 10 MPH.

FRIDAY: Sunny to partly cloudy. Highs around 80, cooler Cape Cod and South Coast. Wind W up to 10 MPH shifting to S.

FRIDAY NIGHT: Clear. Lows around 60, some 50s interior valleys. Wind light S.

SATURDAY: Sun mixed with high clouds. Highs upper 70s to middle 80s, coolest South Coast. Wind SW 5-15 MPH.

SATURDAY NIGHT: Partly to mostly cloudy. Chance of showers and thunderstorms overnight. Lows in the 60s. Wind SW 10-20 MPH.

SUNDAY: Variably cloudy. Episodes of scattered showers and thunderstorms. Highs middle 70s to lower 80s, coolest South Coast. Wind SW to S 10-20 MPH.

MONDAY: Mostly cloudy. Episodes of showers/thunderstorms. Low 66. High 80.

TUESDAY: Partly sunny. Isolated showers. Low 64. High 84.

WEDNESDAY: Partly cloudy. Low 61. High 81.

THURSDAY:  Mostly sunny. Low 64. High 83.

8:44PM

Weather changes will be plenty for the next several days. First a hot and breezy Wednesday not without a thunderstorm threat in the afternoon and evening, especially northwest of Boston where some strong to severe storms are possible. This will be triggered by a cold front sliding in from the Great Lakes and nearby Canada. The details of the thunderstorms will be worked out and updated through comments and on the Facebook page (for those who have access to it).

By Thursday, the front responsible for the storms will also be introducing much cooler air, but the front itself maybe sluggish so clouds and a shower threat will linger especially in eastern areas for a while before improvement arrives. High pressure will bring this improvement as it starts to build in, and then will deliver a couple great days Friday and Saturday, with lower humidity but a warming trend. And then  the next change will be taking place as a trough of low pressure, again rather deep for the time of year, drops out of Canada into the Great Lakes and Midwest and sends increasing moisture this way during Sunday and Monday, at which time some significant shower and thunderstorm activity is likely to develop. The trough should start to lift into southeastern Canada and weaken by next Tuesday with improvement but still some risk of a shower as humidity will likely be on the higher side.

Forecast for southeastern New England…

TONIGHT: Areas of low clouds and fog, especially coastal areas and Cape  Cod. Clear but hazy elsewhere. More humid. Lows 65-70. Wind SW 5-15 MPH.

WEDNESDAY: Any low clouds and fog burning off early then hazy sunshine but developing clouds in the afternoon, some possibly building into thunderstorms and a few areas mainly northwest of Boston, and also a line of storms possibly approaching from the west by evening. Any storms may be strong. Humid. Highs from near 80 Cape Cod and 80s South Coast to around 90 elsewhere. Wind SW 10-20 MPH with higher gusts.

WEDNESDAY NIGHT: Variably cloudy with a chance of showers and thunderstorms. Patchy fog late. Humid. Lows 65-70. Wind variable 5-15 MPH, locally gusty near storms.

THURSDAY: Mostly cloudy with a chance of showers through midday then slow clearing west to east. Lowering humidity. Highs in the 70s. Wind mostly N to NE 5-15 MPH.

FRIDAY: Mostly sunny. Low 59. High 80.

SATURDAY: Mostly sunny. Low 63. High 85.

SUNDAY: Increasing clouds. PM showers. Low 65. High 82.

7:06AM

High pressure builds over the region today into Wednesday allowing more typical July warmth to invade the region, but only briefly, as a cold front will move into the region late Wednesday, putting an end to the short-lived warm spell by Thursday. But it does set us up for a nice Friday and Saturday before the next trough from the west brings shower threats Sunday into early next week.

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

MONDAY: Variably cloudy. Chance of showers. Low 65. High 80.

6:30PM

Just beyond the mid point of July, it really is still early Summer, and we’ve had some very  nice weekends so far this season. This particular weekend may not have been as nice as many of the others but it wasn’t terrible either. But now it’s time to look ahead to the coming week!

On Monday we will find ourselves under the influence of a building high pressure ridge aloft but still low pressure on an old frontal boundary east of the region over the ocean. This means fair weather but air still modified by the cooler ocean. We get rid of that and get a land breeze going Tuesday and Wednesday, which will be much warmer days, almost hot! Almost… Well it may feel  hot to many because we have not had that many hot days so far this Summer.  Will anyone reach 90? If it is going to happen this most likely day is  Wednesday, which will have a moderate westerly wind ahead of an approaching cold front and high pressure aloft. This approaching front may set off isolated thunderstorms mainly well west and north of Boston late Wednesday with a better chance of more organized shower and thunderstorm activity holding off until late Wednesday night or Thursday, depending on the timing of the cold front. This front is expected to move along enough to allow fair weather and mild to warm, drier air to dominate the end of the week. Though it may not be completely cloud-free as some cooler air will be aloft and can initiate cloud development Friday and Saturday. A larger scale trough is expected to approach from the west and the weather may go downhill again before next weekend is over.
