10:33AM

DAYS 1-5 (JULY 30-AUGUST 3)
No big changes as far as what was discussed on the last post. High pressure dominates the last 2 days of July and into the early part of August as the pattern transitions toward one with high pressure more in control. You’ll start to notice a more classic summer feel as August gets underway.
TODAY: Mostly sunny. Highs 72-77 coast, 77-82 interior. Wind NE to N 5-15 MPH becoming variable.
TONIGHT: Mostly clear. Lows 52-57 interior, 57-62 coast/urban areas. Wind light variable.
MONDAY: Mostly sunny. Highs 77-82 coast, 82-87 interior. Wind light S with sea breezes.
TUESDAY: Mostly sunny. Lows from the upper 50s to middle 60s. Highs in the 80s.
WEDNESDAY: Partly cloudy. Isolated afternoon thunderstorms. Humid. Lows in the 60s. Highs in the 80s.
THURSDAY: Partly sunny. Scattered afternoon thunderstorms. Humid. Lows from the upper 60s to lower 70s. Highs from the middle 80s to lower 90s, cooler South Coast.

DAYS 6-10 (AUGUST 4-8)
A pattern of high pressure off the East Coast and a trough of low pressure centered around the Great Lakes will result in humid weather with occasional opportunities for showers and thunderstorms during this period. The greatest shower/storm threat appears to be centered around August 6, but will depend on position of trough and other factors, so much fine tuning will take place in the days ahead.

DAYS 11-15 (AUGUST 9-13)
Similar pattern but stronger high pressure and weaker trough means warmer to hotter and more isolated shower/thunderstorm activity during this period.

1:21PM

DAYS 1-5 (JULY 29-AUGUST 2)
As we go through the last few days of July 2017, a pattern that has been fairly persistent will be on its last legs. But change does not come soon enough to save us from a weekend of below average temperatures, which may be great news to many people that don’t appreciate heat, and not so great news to others who were looking forward to some hot summer weather for the beach and pool time. This is the way of it. The fact remains, the weather is the weather, and no amount of wishing or superstitious behavior will alter what is to take place. However, all is not lost, because half of the weekend will be quite nice, when you consider the consensus of opinion, and that will be Sunday, which will feature more sun and less wind but still dry air. Today is a cloudier, cooler, and breezier day in response to a wave of low pressure moving out south of New England. As it departs, high pressure builds in for Sunday and Monday and July ends quite nicely. Pattern transition will be underway as August begins, starting with an increase in humidity and warm weather Tuesday and Wednesday…
THIS AFTERNOON: Clouds thickest over southeastern MA, RI, and eastern CT where spotty light showers are possible, and even a period of rain over Nantucket and possibly Martha’s Vineyard. Thinner clouds to the northwest. Slow clearing trend starting later in the day. Highs 65-70 immediate coast, 70-75 elsewhere. Wind NE 5-15 MPH except 15-25 MPH along the South Coast, shifting more to the N late.
TONIGHT: Clearing. Patchy fog in low-lying areas. Lows 48-53 interior areas, coolest over valleys/swamps/bogs, 53-58 coast. Wind light N.
SUNDAY: Mostly sunny. Highs 72-77 coast, 77-82 interior. Wind NE to N 5-15 MPH becoming variable.
SUNDAY NIGHT: Mostly clear. Lows 52-57 interior, 57-62 coast/urban areas. Wind light variable.
MONDAY: Mostly sunny. Highs 77-82 coast, 82-87 interior. Wind light S with sea breezes.
TUESDAY: Mostly sunny. Lows from the upper 50s to middle 60s. Highs in the 80s.
WEDNESDAY: Partly cloudy. Isolated afternoon thunderstorms. Humid. Lows in the 60s. Highs in the 80s.

DAYS 6-10 (AUGUST 3-7)
A pattern of high pressure off the East Coast and a trough of low pressure centered around the Great Lakes will result in humid weather with occasional opportunities for showers and thunderstorms during this period.

DAYS 11-15 (AUGUST 8-12)
Similar pattern but stronger high pressure and weaker trough means warmer to hotter and more isolated shower/thunderstorm activity during this period.

5:21PM

DAYS 1-5 (JULY 28-AUGUST 1)
Apologies for very late update. Quick summary: Wave of low pressure passes south of New England tonight and early Saturday with some wet weather favoring the South Coast area and some spotty light rain or drizzle getting a bit further north possibly before it all moves away and leaves the balance of the weekend dry. Temperatures will run below seasonal averages this weekend. The pattern changes starting Monday and Tuesday as we say bye to July and hello to August into a more consistent summer-feeling one. Will go into this more on tomorrow’s post. Quick forecast update now…
THROUGH SUNSET: Partly cloudy with slight risk of isolated showers. Temperatures in the 70s, coolest at the coast. Wind light variable with sea breezes diminishing.
TONIGHT: Mostly cloudy. Chance of light rain mainly far southern areas overnight. Lows 55-62. Wind E to NE 5-15 MPH except 15-25 MPH with higher gusts near the South Coast.
SATURDAY: Mostly cloudy morning with a chance of light rain/drizzle favoring far southern areas. Slow clearing afternoon. Highs 68-77, coolest South Coast. Wind NE 5-15 MPH except 15-25 MPH with higher gusts in the morning, becoming N 5-15 MPH all areas afternoon.
SATURDAY NIGHT: Mostly clear. Patchy valley, swamp, and bog fog. Lows 48-55 interior areas, coolest valleys, and 55-62 coast. Wind light N.
SUNDAY: Mostly sunny. Highs 75-80 coast, 80-85 interior. Wind light variable with sea breezes.

TUESDAY: Mostly sunny to partly cloudy. Lows in the 60s. Highs in the 80s.

DAYS 6-10 (AUGUST 2-6)
Typical early August pattern with higher humidity and a daily risk of isolated to scattered showers and thunderstorms, though the chance may increase later in the period.

DAYS 11-15 (AUGUST 7-11)
A fairly warm/humid pattern with occasional showers/thunderstorms is expected.

7:42AM

DAYS 1-5 (JULY 27-31)
A warm front combo today allows clouds to dominate, along with a risk of showers and later a few thunderstorms. This front pushes through far enough for fair weather to make a return for Friday, and then it will be about how close low pressure comes Friday night and Saturday, and how fast it departs. Staying with the same idea as yesterday for now for the weekend, with high pressure in control by Sunday, and into Monday as well.
TODAY: Mostly cloudy. Scattered showers. Isolated thunderstorms later. More humid. Highs 75-82. Wind S 5-15 MPH becoming SW.
TONIGHT: Mostly cloudy. Scattered showers and a slight chance of thunderstorms early. Patchy fog. Humid. Lows 63-69. Wind light SW becoming W.
FRIDAY: Partly cloudy. Highs 77-84. Wind NW 5-15 MPH shifting to N.
FRIDAY NIGHT: Mostly cloudy. Chance of rain overnight. Lows 62-68. Wind light variable becoming E 5-15 MPH.
SATURDAY: Mostly cloudy. Chance of rain in the morning. Highs 70-77. Wind E 5-15 MPH becoming variable.
SUNDAY: Mostly sunny. Lows in the 50s. Highs in the 70s.
MONDAY: Mostly sunny. Lows from the middle 50s to lower 60s. Highs from the middle 70s to lower 80s.

DAYS 6-10 (AUGUST 1-5)
A warmer pattern with westerly flow aloft and weak weather systems providing a risk of showers and thunderstorms a couple of times.

DAYS 11-15 (AUGUST 6-10)
A similar pattern to the 6-10 day period is expected.

7:14AM

DAYS 1-5 (JULY 26-30)
Making a few adjustments in timing of systems for this update. We still get a great day today courtesy of a high pressure area overhead. However, adding more cloudiness and eventual shower/thunderstorm risk to Thursday’s forecast based on a cold front pushing in more quickly. The biggest change to the forecast comes with Friday/Saturday as it appears enough dry air will push in behind Thursday’s cold front to make Friday a generally nice day, and then the area of low pressure that appeared ready to make Friday nasty may pass a little further south and a little later, bringing unsettled weather later Friday night into part of Saturday, and hopefully moving along enough for a better ending to Saturday and then fair weather Sunday as high pressure returns. One thing seems certain, the weekend will be cool for the end of July.
TODAY: Mostly sunny. Highs 76-83, but cooling back in some coastal areas. Wind W 5-15 MPH morning, becoming light variable with sea breezes in the afternoon.
TONIGHT: Mostly clear. Lows 58-65. Wind light S.
THURSDAY: Variably cloudy. Chance of showers/thunderstorms afternoon to early evening. More humid. Highs 77-84. Wind SW 10-20 MPH.
FRIDAY: Partly sunny daytime. Clouds return at night with a chance of rain late. Lows in the 60s. Highs from the middle 70s to lower 80s.
SATURDAY: Mostly cloudy with a chance of rain morning. Clearing afternoon. Lows in the 60s. Highs in the 70s.
SUNDAY: Mostly sunny. Lows in the 50s. Highs in the 70s.

DAYS 6-10 (JULY 31-AUGUST 4)
The feel of summer returns as a more westerly flow dominates aloft and high pressure retreats early in the period and is replaced later in the period. In between a frontal system may bring a few showers/thunderstorms around August 2 or 3.

DAYS 11-15 (AUGUST 5-9)
Fair and a little drier early in the period then humidity increases and shower and thunderstorm threat returns.

7:23AM

DAYS 1-5 (JULY 25-29)
We had our very cool and wet Monday, but improvement will only be partial today as it will be less wet, but still fairly overcast and cool. Full improvement sneaks in tonight as the sky clears and sets up a beautiful summer day Wednesday as high pressure builds over the region. High pressure slips offshore and humidity starts to increase Thursday, as well as cloudiness later, and this will set up a potentially very wet day Friday as a potent disturbance move in from the west. Still need to work out details of this event as it gets closer.
TODAY: Mostly cloudy. Patchy drizzle. Scattered showers. Highs 63-70. Wind N up to 10 MPH.
TONIGHT: Clearing. Lows 55-62. Wind light NW.
WEDNESDAY: Mostly sunny. Highs 76-83, but cooling back in some coastal areas. Wind W 5-15 MPH morning, becoming light variable with sea breezes in the afternoon.
THURSDAY: Partly cloudy. Chance of showers/thunderstorms at night. More humid. Lows in the 60s. Highs in the 80s.
FRIDAY: Mostly cloudy. Showers/thunderstorms likely. Humid. Lows in the 60s. Highs from the middle 70s to lower 80s.
SATURDAY: Mostly cloudy with lingering showers morning. Clearing afternoon. Lowering humidity. Lows in the 60s. Highs in the 70s.

DAYS 6-10 (JULY 30-AUGUST 3)
High pressure moves in with fair/warmer weather July 30-31. Humidity increases along with some risk of showers/thunderstorms at times August 1-3.

DAYS 11-15 (AUGUST 4-8)
Fair and a little drier early in the period then humidity increases and shower and thunderstorm threat returns.

7:19AM

DAYS 1-5 (JULY 24-28)
Cool and unsettled weather starts the week as a significant disturbance rides along a boundary near the New England South Coast. Plentiful moisture and good focus for it may result in a band of heavy rain, potentially leading to some flooding somewhere near the South Coast during the day today. It will continue cool and unsettled Tuesday as elongated low pressure hangs around to the south. High pressure builds in Wednesday with nice weather returning, including a warming trend which will last through Thursday. The next disturbance may be quite potent and is expected to arrive Friday with a shower/thunderstorm risk.
TODAY: Overcast. Rain likely, heavy at times especially South Coast. Temperatures fall slowly then steady 58-66. Wind NE 5-15 MPH interior, 15-25 MPH coast with a few higher gusts possible.
TONIGHT: Cloudy. Patchy light rain. Lows 56-63. Wind light NE.
TUESDAY: Mostly cloudy. Scattered showers. Highs 63-70. Wind N up to 10 MPH.
TUESDAY NIGHT: Clearing. Lows 55-62. Wind light NW.
WEDNESDAY: Mostly sunny. Highs 76-83. Wind W 5-15 MPH.
THURSDAY: Partly cloudy. Chance of showers/thunderstorms at night. More humid. Lows in the 60s. Highs in the 80s.
FRIDAY: Mostly cloudy. Chance of showers/thunderstorms. Humid. Lows in the 60s. Highs from the middle 70s to lower 80s.

DAYS 6-10 (JULY 29-AUGUST 2)
Improving weather July 29 and fair, warm weather July 30-31. Shower and thunderstorm threat and high humidity the first couple days of August.

DAYS 11-15 (AUGUST 3-7)
Fair and a little drier early in the period then humidity increases and shower and thunderstorm threat returns.

2:09AM

DAYS 1-5 (JULY 23-27)
Can’t give myself credit for a good forecast Saturday as there was much less sun than I had forecast. We will get back into some sunshine today as drier air pushes down from the north, but it will be cooler as well, and this will set up a cool and eventually wet day Monday as low pressure makes a run at southern New England from the west. Improvement will arrive Tuesday but there will still be a shower threat. Still looking for high pressure to bring fair weather and a warm up at midweek although an approaching cold front may bring a thunderstorm risk as early as the end of the day Thursday.
TODAY: Variably cloudy early with a risk of rain briefly along the South Coast, then partly cloudy to mostly sunny. Highs 72-77 coast, 78-83 interior. Wind light variable then NE to E 5-15 MPH.
TONIGHT: Clouding over. Lows 62-67. Wind light E.
MONDAY: Cloudy. Periods of rain. Embedded downpours possible. Humid. Highs 68-75. Wind E 5-15 MPH.
TUESDAY: Mostly cloudy. Chance of showers, favoring the morning. Lows in the 60s. Highs in the 70s.
WEDNESDAY: Mostly sunny. Lows in the 60s. Highs in the 80s, some 70s South Coast.
THURSDAY: Partly cloudy. Chance of thunderstorms evening or night. Lows in the 60s. Highs in the 80s.

DAYS 6-10 (JULY 28-AUGUST 1)
Higher humidity and a shower/thunderstorm risk at times to start the period then drier/warmer for a few days before a shower/thunderstorm threat returns about August 1.

DAYS 11-15 (AUGUST 2-6)
Shower/thunderstorm threats most likely very early and again late period. Temperatures near to above normal.

2:24AM

DAYS 1-5 (JULY 22-26)
This update shows no major changes but will make some adjustments. Essentially a good weekend. The interruption will come as the remains of a thunderstorm complex passes south of the region early Sunday when some rain may get into the South Coast region briefly. We’ll have to deal with a mixture of some high cloudiness and some smoke from distant fires in western Canada which will filter and blot out the sun at times today, but now expecting enough dry air to push in from the north to allow for more sun on Sunday than previously expected, though it will still be a cooler day than Saturday because of a northerly to easterly air flow. Monday looks like the wet day as low pressure makes a more direct run at the region, but timing of the onset of the rain is uncertain. Leaning toward a wetter afternoon than morning at this point. This system will slowly exit on Tuesday and high pressure will return with nice summer weather by Wednesday.
TODAY: Limited sun morning, more sun afternoon. Highs 77-84 South Coast, 85-91 elsewhere. Wind W 5-15 MPH.
TONIGHT: Variably cloudy. Lows 62-70, warmest urban areas. Wind light variable.
SUNDAY: Variably cloudy early with a risk of rain briefly along the South Coast, then partly cloudy to mostly sunny. Highs 75-80 coast, 80-85 interior. Wind light variable then NE to E 5-15 MPH.
MONDAY: Cloudy. Periods of rain, favoring the afternoon and night. Lows in the 60s. Highs in the 70s.
TUESDAY: Mostly cloudy. Chance of showers, favoring the morning. Lows in the 60s. Highs in the 70s.
WEDNESDAY: Mostly sunny. Lows in the 60s. Highs in the 80s, some 70s South Coast.

DAYS 6-10 (JULY 27-31)
Higher humidity and a shower/thunderstorm risk at times July 27-29 then generally warm/dry weather expected for the final days of July.

DAYS 11-15 (AUGUST 1-5)
Another frontal system the first couple days of August should bring a thunderstorm risk otherwise mainly dry and normally warm and somewhat humid summer weather is expected.

2:53PM

DAYS 1-5 (JULY 21-25)
High Summer! We’re in it now and it feels like it today with high pressure in control, moderate but slightly lowering humidity, and very warm to hot air. The weather over the weekend had looked a little iffy but I’m more confident today that we get through the weekend largely rain-free, but not cloud-free. There should still be a fair amount of sun Saturday as dry air keeps most of the cloudiness at bay even though it will try to move in. They should win the battle a little more by Sunday though it looks like the next low pressure area along a front to the southwest and south of the region will dive to the southeast and take the rain with it. By Monday, the next wave will move more to the east northeast and we should get wet then, with this lingering into Tuesday.
REST OF THIS AFTERNOON: Sunshine. Highs 82-87 Cape Cod, 88-93 elsewhere. Wind W 5-15 MPH.
TONIGHT: Mostly clear. Lows 62-70, warmest urban areas. Wind light W.
SATURDAY: Mostly sunny to partly cloudy. Highs 77-84 South Coast, 85-91 elsewhere. Wind W 5-15 MPH.
SATURDAY NIGHT: Variably cloudy. Lows 62-70, warmest urban areas. Wind light variable.
SUNDAY: Variably cloudy. Highs 75-80 coast, 80-85 interior. Wind light variable to NE.
MONDAY: Cloudy. Periods of rain. Lows in the 60s. Highs in the 70s.
TUESDAY: Mostly cloudy. Chance of showers. Lows in the 60s. Highs in the 70s.

DAYS 6-10 (JULY 26-30)
As we head into the home stretch of July, there will be additional changes as we are in a progressive pattern with a ridge in the western US and a northwest flow in the northeastern US. High pressure will bring dry and warmer weather July 26. A front approaches later July 27 and moves through during July 28 with a chance of showers/thunderstorms. High pressure should bring fair weather again thereafter.

DAYS 11-15 (JULY 31-AUGUST 4)
One more front around the first couple days of August should bring a thunderstorm risk otherwise mainly dry and normally warm and somewhat humid summer weather is expected.

7:31AM

DAYS 1-5 (JULY 20-24)
Forecast update.
Discussion added later.
TODAY: Mostly sunny to partly cloudy. Slight risk of isolated thunderstorms. Hazy. Humid. Highs 78-85 South Coast, 86-92 elewhere. Wind SW 10-20 MPH.

DAYS 6-10 (JULY 25-29)
The start of the period will feature below normal temperatures and a risk of showers as low pressure hangs around and high pressure stays to the north. The middle to end of the period will feature a warming trend with dry weather. Late period expected warm and humid with showers/thunderstorms followed by drying again.

DAYS 11-15 (JULY 30-AUGUST 3)
Seasonably warm/drier early period, then increasing heat and humidity as high pressure tries to build off the East Coast. Isolated showers/thunderstorms later in the period.

3:52PM

DAYS 1-5 (JULY 19-23)
The feel of summer is here and will continue for a few days, with some heat (not too high) and humidity (fairly high) through Thursday night before it dries out a little at the end of the week behind a cold front. A little shift in the pattern will bring cooler air by Sunday with low pressure to the south, high pressure to the north, and some unsettled weather.
REMAINDER OF AFTERNOON: Sun and passing clouds. Slight risk of isolated showers. Humid. Highs 78-85 South Coast, 86-92 elsewhere. Wind W 10-20 MPH.

SUNDAY: Mostly cloudy. Chance of showers. Lows in the 60s. Highs in the 70s.

DAYS 6-10 (JULY 24-28)
The first couple days of the period will feature below normal temperatures and a risk of showers as low pressure hangs around and high pressure stays to the north. The middle to end of the period will feature a warming trend, starting drier and turning more humid with time, and a chance of showers/thunderstorms by the very end of the period.

DAYS 11-15 (JULY 29-AUGUST 2)
Seasonably warm/drier early period, then increasing heat and humidity as high pressure tries to build off the East Coast. Isolated showers/thunderstorms later in the period.

9:46AM

DAYS 1-5 (JULY 18-22)
Humidity and July warmth dominates during the next few days. A front pushing through may bring somewhat drier air by Friday and Saturday.
TODAY: Partly cloudy. Isolated to scattered thunderstorms, mainly late day and evening. Humid. Highs 77-86, coolest South Coast. Wind S 5-15 MPH.
TONIGHT: Low clouds near the coast. Partly cloudy interior. Humid. Lows 62-68. Wind light S.
WEDNESDAY: Partly sunny. Isolated afternoon showers/thunderstorms. Humid. Highs 78-85 along the coast to 86-92 interior areas.

SATURDAY: Partly cloudy. Lows in the 60s. Highs from the upper 70s to middle 80s.

DAYS 6-10 (JULY 23-27)
A few episodes of showers July 23-24 with a front nearby. Briefly cooler as well. Warmer with isolated showers and thunderstorms thereafter.

DAYS 11-15 (JULY 28-AUGUST 1)
Trending hotter. Risk of a few showers and thunderstorms at times.

7:22AM

DAYS 1-5 (JULY 17-21)
Again no major changes to the forecast going forward. Humidity returns and eventually some heat during the next several days. A front pushing through may bring somewhat drier air by Friday but I’m not going to guarantee this quite yet.
TODAY: Partly cloudy. Slight risk of an isolated late-day shower. More humid. Highs 77-86, coolest South Coast. Wind light S.
TONIGHT: Low clouds near the coast. Partly cloudy interior. Humid. Lows 62-68. Wind light S.
TUESDAY: Partly cloudy. Isolated to scattered thunderstorms, mainly late day and evening. Humid. Highs 77-86, coolest South Coast. Wind S 5-15 MPH.
WEDNESDAY: Partly sunny. Isolated to scattered thunderstorms. Lows from the middle 60s to lower 70s. Highs from the upper 70s to middle 80s along the coast and the upper 80s to lower 90s interior areas.
THURSDAY: Variably cloudy. Scattered showers/thunderstorms. Lows from the middle 60s to lower 70s. Highs from the lower to middle 80s South Coast, middle 80s to lower 90s elsewhere.
FRIDAY: Partly cloudy. Slight chance of showers. Less humid. Lows in the 60s. Highs in the 80s.

DAYS 6-10 (JULY 22-26)
The large scale pattern is expected to feature a ridge of high pressure over the western US and a weak to moderate northwesterly flow over the northeastern US. This pattern is typically seasonably warm with brief alternating modified heat and modified cooler shots, timing of these not really doable beyond a few days. This pattern also produces opportunities for showers/thunderstorms especially with air mass changes. The greatest risks at this point appear to be mid to late period.

DAYS 11-15 (JULY 27-31)
The late days of July should feature a somewhat similar pattern but trend may be for more heat as the hot ridge from the west flattens. Also continuing to see signs of new high pressure establishing near or off the East Coast which would also translate to a hotter pattern. Mainly isolated to scattered showers/thunderstorms are possible but this would be a largely rain-free pattern.

8:16AM

DAYS 1-5 (JULY 16-20)
There is a fair chance of observing the aurora borealis (northern lights) tonight as energy from a storm on the sun reaches the atmosphere. Looking north, the best chance to observe these will be away from natural lights and obviously under as clear a sky as possible. Do what you can for the first one and hope mother nature cooperates on the second. This update essentially has no changes from yesterday’s, so just a quick forecast and yesterday’s discussion generally applies. From here forward is basically yesterday’s. The weather pattern will undergo the first part of a transition in which a hot ridge of high pressure establishes itself in the western US. What tries to be a passing trough through the northeastern US will shear apart with a piece moving along to the east and the other part dropping to the south and cutting off from the flow over the southern Great Lakes and Ohio Valley when it will then start to drift slowly to the east. This, along with a weak surface high trying to stay established off the East Coast means Monday-Thursday turn somewhat more humid and run the risk of a few showers and thunderstorms at times.
TODAY: Partly cloudy. Highs 77-86, coolest South Coast. Wind S to SW 5-15 MPH.
TONIGHT: Mostly clear. Lows 62-68. Wind light S.
MONDAY: Partly cloudy. Slight risk of isolated showers. Lows in the 60s. Highs from the upper 70s to middle 80s, coolest South Coast.
TUESDAY: Partly cloudy. Isolated to scattered thunderstorms. Lows in the 60s. Highs from the upper 70s to middle 80s, coolest South Coast.
WEDNESDAY: Partly sunny. Isolated to scattered thunderstorms. Lows from the middle 60s to lower 70s. Highs from the upper 70s to middle 80s along the coast and the upper 80s to lower 90s interior areas.
THURSDAY: Variably cloudy. Scattered showers/thunderstorms. Lows from the middle 60s to lower 70s. Highs from the lower to middle 80s South Coast, middle 80s to lower 90s elsewhere.

DAYS 6-10 (JULY 21-25)
The large scale pattern is expected to feature a ridge of high pressure over the western US and a weak to moderate northwesterly flow over the northeastern US. This pattern is typically seasonably warm with brief alternating modified heat and modified cooler shots, timing of these not really doable beyond a few days. This pattern also produces opportunities for showers/thunderstorms especially with air mass changes. The greatest risks at this point appear to be July 21 and again late in the period.

DAYS 11-15 (JULY 26-30)
The late days of July should feature a somewhat similar pattern but trend may be for more heat as the hot ridge from the west flattens. Also continuing to see signs of new high pressure establishing near or off the East Coast which would also translate to a hotter pattern. Mainly isolated to scattered showers/thunderstorms are possible but this would be a largely rain-free pattern.
