Tuesday Forecast

7:18AM

DAYS 1-5 (JULY 31-AUGUST 4)
Humidity’s getting ready to make a come-back, to be felt increasing slightly later today but much more noticeably during Wednesday as a warm front passes through. This front may bring a few showers and then trigger a few thunderstorms as it passes. Thursday through Saturday will be very warm and humid days with a daily risk for a few showers and storms as we’ll be in a southwesterly flow around a Bermuda High. Forecast details…
TODAY: Sun/cloud mix. Highs 78-86, coolest coast. Wind light variable with sea breezes.
TONIGHT: Mostly cloudy. Humid. Slight chance of a shower. Lows 66-72. Wind light S.
WEDNESDAY: Mostly cloudy with scattered showers morning. Partly sunny with isolated thunderstorms afternoon. Humid. Highs 82-90. Wind S to SW 5-15 MPH.
WEDNESDAY NIGHT: Partly cloudy. Patchy fog. Humid. Lows 66-73. Wind light SW.
THURSDAY: Partly sunny. Isolated to scattered showers/thunderstorms. Humid. Highs 83-92, coolest South Coast. Wind SW 5-15 MPH.
FRIDAY & SATURDAY: Partly sunny. Isolated to scattered showers/thunderstorms. Humid. Lows from the upper 60s to middle 70s. Highs from the middle 80s to lower 90s, coolest South Coast.

DAYS 6-10 (AUGUST 5-9)
Ridge dominates the East Coast again with more heat and humidity resulting but a slightly lower risk of showers and storms August 5-6 before the threat increases again as the ridge nudges eastward and the heat eases slightly mid to late period.

DAYS 11-15 (AUGUST 10-14)
Ridge is a bit more to the east and trough a little closer to the region early in the period with a better shower/thunderstorm risk, then ridge comes back west yet again with additional heat and humidity toward the end of the period.

Monday Forecast

7:11AM

DAYS 1-5 (JULY 30-AUGUST 3)
Today’s update finds no need again for major changes to the forecast. After coming down a little bit later in the weekend, the humidity remains below the oppressive category early this week as the last couple days of July go by, and then as the Bermuda High takes over again it’s back as we start August, along with the risk of showers and thunderstorms at times. Heat won’t be too high, although humidity compensates for that and makes it feel hotter anyway. Forecast details…
TODAY: Partly cloudy. Highs 78-86, coolest coast. Wind light variable with sea breezes.
TONIGHT: Partly cloudy. Lows 63-69. Wind light SW.
TUESDAY: Variably cloudy. Slight risk of a late day shower. More humid late. Highs 78-85 coast, 85-92 interior. Wind SW 5-15 MPH.
TUESDAY NIGHT: Mostly cloudy. Humid. Slight chance of a shower. Lows 66-72. Wind light SW.
WEDNESDAY: Partly sunny. Isolated to scattered afternoon showers and thunderstorms. Humid. Highs 82-90, coolest South Coast. Wind SW 5-15 MPH.
THURSDAY & FRIDAY: Partly sunny. Isolated to scattered showers/thunderstorms. Humid. Lows from the middle 60s to lower 70s. Highs in the 80s to around 90.

DAYS 6-10 (AUGUST 4-8)
Ridge dominates the East Coast again with more heat and humidity resulting but a slightly lower risk of showers and storms August 4-6 before the threat increases again as the ridge nudges eastward and the heat eases slightly later in the period.

DAYS 11-15 (AUGUST 9-13)
Ridge is a bit more to the east and trough a little closer to the region early in the period with a better shower/thunderstorm risk, then ridge comes back west yet again with additional heat and humidity toward the end of the period.

Sunday Forecast

11:06AM

DAYS 1-5 (JULY 29-AUGUST 2)
Quick and easy update today, WHW readers! No changes to the forecast. High pressure brings a humidity reprieve today and Monday before our friendly Atlantic ridge starts to retrograde (move westward) and return the humidity as July ends and August gets underway. The shower and thunderstorm threat that has been present recently will also take a break for a few days, with the first chance of anything returning being late Tuesday, albeit not a great chance, and then we’ll start to see the daily risk of them, though not likely widespread, by the middle of next week. And although this midweek storm risk is several days away, I have seen some early signs that the pattern may support severe storms where they occur, so something to keep in mind going forward. Forecast details…
TODAY: Filtered sunshine. Less humid. Highs 78-85, coolest coast. Wind light variable with sea breezes.
TONIGHT: Mostly clear. Lows 62-68. Wind light variable.
MONDAY: Partly cloudy. Highs 78-86, coolest coast. Wind light variable with sea breezes.
MONDAY NIGHT: Partly cloudy. Lows 63-69. Wind light SW.
TUESDAY: Partly sunny. Slight chance of late-day showers or thunderstorms. More humid. Highs 78-85 coast, 85-92 interior. Wind SW 5-15 MPH.
WEDNESDAY & THURSDAY: Partly sunny. Isolated to scattered showers/thunderstorms. Humid. Lows from the middle 60s to lower 70s. Highs in the 80s to lower 90s.

DAYS 6-10 (AUGUST 3-7)
Ridge dominates the East Coast again with more heat and humidity resulting. A daily opportunity for isolated to scattered showers and thunderstorms but much of this time will be rain-free.

DAYS 11-15 (AUGUST 8-12)
Ridge slides back east and takes the edge off the heat, but overall pattern still warm/humid, with occasional opportunities for showers/thunderstorms as the Midwest trough gets a little closer again.

Saturday Forecast

9:51AM

DAYS 1-5 (JULY 28-AUGUST 1)
As the July days slip toward their conclusion and August arrives we will go through a period of “pattern readjustment”, or basically our oscillating Atlantic ridge will finish its slip to the east and then start to come back to the west, in turn pushing the Great Lakes & Midwest trough back to the west as well after having allowed it to slip eastward. This eastward displacement of the trough is what is responsible for our current unsettled weather, i.e., the shower and thunderstorm threat as a couple fronts move slowly through the region. The final front in the series is over the area now and will take the entirety of today and this evening to finally make its way offshore, so while this is ongoing we’ll have to be on the look-out for showers and thunderstorms. No, this is not going to turn into a widespread rain event or a washed-out Saturday, but if you have outdoor plans you’ll want to keep an eye on the weather, just in case you have to “get out of the way” as a shower or storm passes through. This is not the type of day to cancel outdoor plans, but we should be aware of what can happen. After this come two quiet and summery days Sunday and Monday thanks to high pressure being in control. This also comes with somewhat lower humidity than what we have seen recently. That humidity starts to make a comeback Tuesday when a shower or storm is possible, especially late, and by Wednesday of next week we’re back in the muggy pattern with a shower and thunderstorm threat. Forecast details…
TODAY: Partly cloudy. Isolated to scattered showers and thunderstorms. Any storms can contain downpours, frequent lightning, and briefly gusty wind, but should not last too long at any one location. Highs 78-84 coast, 84-90 interior. Wind W 5-15 MPH.
TONIGHT: Partly cloudy. Isolated showers and thunderstorms evening. Lows 64-70. Wind light W.
SUNDAY: Partly sunny. Less humid. Highs 78-85, coolest coast. Wind light variable with sea breezes.

MONDAY: Partly cloudy. Highs 78-86, coolest coast. Wind light variable with sea breezes.
TUESDAY: Partly sunny. Chance of showers and thunderstorms late in the day. More humid. Lows in the 60s. Highs from the upper 70s to upper 80s, coolest coast.
WEDNESDAY: Partly sunny. Isolated to scattered showers/thunderstorms. Humid. Lows from the middle 60s to lower 70s. Highs in the 80s to lower 90s.

DAYS 6-10 (AUGUST 2-6)
Ridge dominates the East Coast again with more heat and humidity resulting. A daily opportunity for isolated to scattered showers and thunderstorms but much of this time will be rain-free.

DAYS 11-15 (AUGUST 7-11)
Ridge nudges back east and takes the edge off the heat, but overall pattern still warm/humid, with occasional opportunities for showers/thunderstorms.

Friday Forecast

7:23AM

DAYS 1-5 (JULY 27-31)
July’s final 5 will present a couple transitions, first from humid to less humid as a couple fronts move through the region, then back to more humid at the end of the period as we start to feel westward expansion of high pressure from the Atlantic once again, as this was the expected predominant pattern starting in late July. These transitions come with at least some shower/thunderstorm risk. Forecast details…
TODAY: Partly to mostly sunny. Highs 78-83 South Coast, 83-88 elsewhere. Wind W 5-15 MPH.
TONIGHT: Variably cloudy. Scattered showers and a slight chance of a thunderstorm west to east late. Lows 63-69. Wind SW 5-15 MPH.
SATURDAY: Partly cloudy. Chance of showers early. Isolated afternoon showers/thunderstorms. Highs 77-85. Wind W 5-15 MPH.

DAYS 6-10 (AUGUST 1-5)
Ridge dominates the East Coast again with more heat and humidity resulting. A daily opportunity for isolated to scattered showers and thunderstorms but much of this time will be rain-free.

DAYS 11-15 (AUGUST 6-10)
Ridge nudges back east, but overall pattern still warm/humid, with occasional opportunities for showers/thunderstorms.

Thursday Forecast

7:21AM

DAYS 1-5 (JULY 26-30)
2 cold fronts head through the region, one during today, another by early Saturday, and they will each take the humidity down a peg, so that by the end of the coming weekend it’s noticeably more comfortable than much of this week has been. Each of these fronts will produce a shower and thunderstorm risk. Today’s risk is higher for most of the WHW forecast area, with the second front producing stronger storms west of the region late Friday which probably weaken as they get into the area and pass through during Friday night and early Saturday. Will weak that as it gets closer. Forecast details…
TODAY: Variably cloudy. Areas of drizzle and lingering showers early. Isolated to scattered showers and thunderstorms midday through afternoon. Humid. Highs 77-84. Wind variable becoming SW 5-15 MPH.
TONIGHT: Mostly clear. Patchy fog. Less humid. Lows 63-70. Wind SW to W 5-10 MPH.
FRIDAY: Mostly sunny into afternoon then becoming partly sunny. Highs 78-83 South Coast, 83-88 elsewhere. Wind W 5-15 MPH.
FRIDAY NIGHT: Variably cloudy. Scattered showers and a slight chance of a thunderstorm west to east late. Lows 63-69. Wind SW 5-15 MPH.
SATURDAY: Partly cloudy. Chance of showers early. Highs 77-85. Wind W 5-15 MPH.
SUNDAY: Partly sunny. Lows in the 60s. Highs from the upper 70s to middle 80s, coolest coast.
MONDAY: Partly cloudy. Lows in the 60s. Highs from the upper 70s to middle 80s, coolest coast.

DAYS 6-10 (JULY 31-AUGUST 4)
Ridge backs up into the East Coast again with more heat and humidity resulting. A daily opportunity for isolated to scattered showers and thunderstorms but much of this time will be rain-free.

DAYS 11-15 (AUGUST 5-9)
Same overall pattern continues, starting very warm to hot then heat easing a little after that with more shower/storm chances as the ridge nudges back to the east.

Wednesday Forecast

7:31AM

DAYS 1-5 (JULY 25-29)
A little more tweaking in a forecast that overall isn’t going to change much at all. Today we’re in the same state as yesterday but the ridge in the Atlantic will be nudging back to the east and allowing a weak cold front to the west to get closer later today and then pass through tomorrow, but only isolated shower activity will take place during the day and evening today, however any may be briefly very heavy. Much of our rain threat will come through between midnight and dawn Thursday morning as a wave of low pressure comes up along and just ahead of the front, which will then be sapped of some of its energy so the shower and thunderstorm risk during the day Thursday, though present, will not be that high. Very slightly drier air arrives Friday but it will probably be one of the warmer days, compensating a bit and having the net overall impact as the days before it. Another front whistles through the region Saturday morning with a brief shower threat and then the balance of the weekend will be quite nice, though again only marginally drier in terms of humidity. Forecast details…
TODAY: Partly sunny. Isolated showers and possible thunderstorms, any of which may produce heavy downpours. Humid. Highs 78-87, coolest South Coast. Wind S 5-15 MPH.
TONIGHT: Mostly cloudy. Showers and possible thunderstorms increase from southwest to northeast especially late night. Humid. Lows 67-74. Wind SW 5-15 MPH becoming variable.
THURSDAY: Mostly cloudy with numerous showers early, then partly sunny with scattered to isolated showers and thunderstorms. Humid. Highs 76-83. Wind variable 5-15 MPH becoming W.
THURSDAY NIGHT: Mostly clear. Less humid. Lows 63-70. Wind W 5-15 MPH.
FRIDAY: Partly cloudy. Less humid. Highs 78-83 South Coast, 83-88 elsewhere. Wind W 5-15 MPH.
SATURDAY: Partly cloudy. Chance of showers early. Lows in the 60s. Highs from the upper 70s to middle 80s, coolest coast.
SUNDAY: Partly sunny. Lows in the 60s. Highs from the upper 70s to middle 80s, coolest coast.

DAYS 6-10 (JULY 30-AUGUST 3)
Overall pattern to remain configured with a trough centered Midwest and Great Lakes and ridge off the East Coast with a fairly humid pattern and a few shower and thunderstorm opportunities. Ridge will be expanding more westward and it may turn hotter as August begins.

DAYS 11-15 (AUGUST 4-8)
Same overall pattern continues… May start rather hot then ease after that with more shower/storm chances as the ridge nudges back to the east.

Tuesday Forecast

7:38AM

DAYS 1-5 (JULY 24-28)
A quick update today finds things pretty much the same. Limited showers today as the ridge is at its westward limit for now, and will then wobble back east and let a front get a little closer later Wednesday then pass through the region Thursday, which will have the greatest shower/storm threat as previously mentioned. Now it does appear that a little drier air will sneak in for the end of the week. No, don’t look for a refreshing Canadian air mass. It will still be humid, just not as humid, and the shower threat will drop off considerably as well. Forecast details…
TODAY: Partly cloudy. Isolated showers and thunderstorms mainly well west of Boston. Humid. Highs 78-87, coolest South Coast. Wind S 5-15 MPH.
TONIGHT: Partly cloudy. Patchy fog. Very humid. Lows 64-72. Wind S 5-15 MPH.
WEDNESDAY: Partly cloudy. Isolated showers and thunderstorms may becoming more scattered to general in western areas later in the day. Humid. Highs 78-87, coolest South Coast. Wind S 5-15 MPH.
WEDNESDAY NIGHT: Mostly cloudy. Showers and possible thunderstorms increase from west to east. Humid. Lows 67-74. Wind SW 5-15 MPH.
THURSDAY: Variably cloudy. Numerous to scattered showers/thunderstorms. Humid. Highs 76-83. Wind SW 5-15 MPH becoming W then variable.
FRIDAY: Partly cloudy. Isolated showers. Less humid. Lows from the middle 60s to lower 70s. Highs from the upper 70s to upper 80s, coolest South Coast.
SATURDAY: Partly cloudy. Lows in the 60s. Highs from the upper 70s to middle 80s, coolest coast.

DAYS 6-10 (JULY 29-AUGUST 2)
Still expecting overall pattern to remain configured with a trough centered Midwest and Great Lakes and ridge off the East Coast with a fairly warm and humid pattern and a few shower and thunderstorm opportunities.

DAYS 11-15 (AUGUST 3-7)
Same pattern continues…

Monday Forecast

7:20AM

DAYS 1-5 (JULY 23-27)
No changes to the forecast at this time other than minor timing tweaks, leaning to Thursday as the other day with a better shower/storm risk. Updated forecast details…
TODAY: Mostly cloudy to partly sunny. Scattered to isolated showers and possible thunderstorms. Very humid. Highs 78-86, coolest South Coast. Wind S 5-15 MPH.
TONIGHT: Partly to mostly cloudy. Patchy fog. Very humid. Lows 64-72. Wind light S.
TUESDAY: Partly cloudy. Isolated showers and thunderstorms mainly late day. Humid. Highs 78-87, coolest South Coast. Wind S 5-15 MPH.
TUESDAY NIGHT: Partly cloudy. Patchy fog. Very humid. Lows 64-72. Wind S 5-15 MPH.
WEDNESDAY: Partly cloudy. Isolated showers and thunderstorms mainly late-day. Humid. Highs 78-87, coolest South Coast. Wind S 5-15 MPH.
THURSDAY: Variably cloudy. Scattered showers/thunderstorms. Humid. Lows from the middle 60s to lower 70s. Highs from the upper 70s to upper 80s, coolest South Coast.
FRIDAY: Partly cloudy. Isolated showers. Humid. Lows from the middle 60s to lower 70s. Highs from the upper 70s to upper 80s, coolest South Coast.

DAYS 6-10 (JULY 28-AUGUST 1)
The overall large scale pattern, as mentioned previously, will feature a low pressure trough around the Midwest and Great Lakes and high pressure off the US East Coast. As the strength and position of the ridge fluctuates, it will help determine days with higher shower and thunderstorm threats. A higher threat is expected early and again late in the period with driest weather during the July 28-29 weekend. Temperatures near to above normal.

DAYS 11-15 (AUGUST 2-6)
Not seeing any major pattern shifts during this period as well.

Sunday Forecast

12:33PM

DAYS 1-5 (JULY 22-26)
Once again my observations around social media and out in public confirm that the general public listens and believes the media’s gloom and doom scenarios. Although it feels like a lost cause at times, I will continue to use the style I always do when forecasting and explaining the weather and its expectations. So with this said, we move forward to say that so far the weather is behaving generally as expected and the upper limits of what was possible have not come to pass, which is a good thing, isn’t it? You’d think people would be happy about that instead of being disappointed that wind damage and areas of flash flooding are not taking place in most of the region. So we have our low moving into the northern Mid Atlantic, our wettest weather in eastern portions of southern New England now into the afternoon, then everything transitions to the more scattered to isolated showers set-up, as explained on yesterday’s blog post. There are no changes to that forecast here, and I will still be working on the timing of the greater shower and thunderstorm threat later in the week. In the mean time, onto the details…
TODAY: Mainly cloudy with numerous showers, especially eastern areas, into mid afternoon along with downpours at times, then these become scattered with partial sun developing at times later in the day. Very humid. Highs 74-82. Wind SE to S 10-20 MPH, higher gusts especially coastal areas where a few gusts to or over 30 MPH are possible.
TONIGHT: Partly cloudy. Isolated to scattered showers and possible thunderstorms. Very humid. Lows 68-75. Wind S 5-15 MPH.
MONDAY: Partly sunny. Scattered to isolated showers and possible thunderstorms. Very humid. Highs 78-86, coolest South Coast.
TUESDAY & WEDNESDAY: Partly cloudy. Isolated showers and thunderstorms mainly late day. Humid. Lows from the middle 60s to lower 70s. Highs from the upper 70s to upper 80s, coolest Cape Cod, warmest interior valleys.
THURSDAY: Partly sunny. Scattered mainly afternoon showers/thunderstorms. Humid. Lows from the middle 60s to lower 70s. Highs from the upper 70s to upper 80s, coolest South Coast.

DAYS 6-10 (JULY 27-31)
The overall large scale pattern, as mentioned previously, will feature a low pressure trough around the Midwest and Great Lakes and high pressure off the US East Coast. As the strength and position of the ridge fluctuates, it will help determine days with higher shower and thunderstorm threats. A higher threat is expected early and again late in the period with driest weather during the July 28-29 weekend. Temperatures near to above normal.

DAYS 11-15 (AUGUST 1-5)
Not seeing any major pattern shifts during this period as well.
