Notes from Rich:
What is the 'Regular’ Schedule.
Weekdays: Morning updates each day before 8AM, Evening Updates before 7PM.
On Weekends: Perhaps a bit later. I like to sleep in.
Every Thursday morning I post the daily forecast through the weekend.
Upcoming Site Update Schedule Changes:
The late day forecast and the every Thursday Weekend Outlook e-mail may both be a bit later this evening.
A partly sunny day today, but clouds will be on the increase as the next system begins to approach the region. Showers return tonight through Friday morning. Some of the thunderstorms may be strong to severe tonight. The weekend is looking mostly dry, but a chance for showers does exist on Saturday. More on that in tonight’s every Thursday Weekend Outlook e-mail blast.
I have begun displaying travel maps for the Independence Day holiday. You can find them in the bottom NEWs Section.
A fairly typical late June weather pattern continues today with warm temperatures, scattered afternoon showers, and a few thunderstorms. A more widespread round of rain arrives tonight into Friday morning, followed by the potential for some strong to severe thunderstorms Friday afternoon if enough sunshine develops. After that, seasonably warm weather continues through much of next week with daily chances for afternoon showers and thunderstorms.
Check out the enhanced "Todays Weather at a Glance" section above.
From the Weather Channel:
Good Morning. Our thoughts are with the people of Venezuela, which is reeling this morning from an extraordinary natural disaster. Yesterday evening, twin earthquakes, the first registering 7.2 magnitude and the second 7.5 (making it the country's strongest quake in over a century) struck within seconds of each other, toppling buildings from the coastal state of La Guaira to the capital city of Caracas. As the sun rises today, it will illuminate a catastrophe. Last night, President Delcy Rodriguez announced that over 32 lives had been lost, and over 700 people had been injured, but warned that those numbers didn't include areas close to the quake's epicenter, where dozens of buildings collapsed. Venezuela's disaster occurred during an active 24-hour period for seismic activity worldwide.
A 5.6-magnitude earthquake shook Northern California earlier in the day, and a 6.9-magnitude quake struck off Japan's coast shortly after the Venezuelan quakes. Seismologists confirm these global events are unrelated coincidences, but they are a good reminder to always have a plan and go-bag ready if you live in earthquake-prone areas.

Key Messages:
- Expect similar highs as yesterday this afternoon with scattered showers and isolated thunderstorms.
- Widespread rain moves in tonight followed by a chance of thunderstorms Friday afternoon.
- Seasonably warm with chances of showers or thunderstorms most days beginning this weekend.
What has changed since the last Forecast Update?
No significant updates were needed this morning as the forecast remains on track. Forecasters made routine updates to the short-term forecast grids and aviation forecast.
What this means for you:
Today will be another warm day with many locations staying dry, but a few afternoon showers and thunderstorms could become briefly strong with gusty winds and small hail. Expect widespread rain tonight into Friday morning, with rainfall amounts generally between one quarter and three quarters of an inch, although isolated areas could receive up to 2 inches. Friday afternoon could bring a risk of severe thunderstorms, especially across New Hampshire and western Maine.

**What Has Changed**
No significant updates were needed this morning as the forecast remains on track. Forecasters made routine updates to the short-term forecast grids and aviation forecast.
**Key Messages**
1. Expect similar highs as yesterday this afternoon with scattered showers and isolated thunderstorms.
2. Widespread rain moves in tonight followed by a chance of thunderstorms Friday afternoon.
3. Seasonably warm with chances of showers or thunderstorms most days beginning this weekend.
**Discussion**
**Key Message 1 Description**
Most locations will remain dry today, but a weak area of low pressure will bring scattered afternoon showers and isolated thunderstorms. Compared to yesterday, a few more showers and storms may drift out of the mountains, although coverage will still be fairly limited.
Forecast guidance indicates moderate atmospheric instability, technically referred to as MUCAPE (Most Unstable Convective Available Potential Energy), between 1000 and 1500 joules per kilogram. Combined with effective wind shear of 25 to 30 knots, a few stronger thunderstorms could develop with gusty winds and small hail.
High temperatures will be similar to yesterday. Most lower elevation areas will reach the middle 70s to lower 80s, while higher elevations remain in the upper 60s to lower 70s. A developing sea breeze will likely keep coastal communities a little cooler than current forecast temperatures.
**Key Message 2 Description**
A stronger upper level disturbance will approach from the west tonight while a warm front lifts north across the region. This will bring widespread rain overnight into Friday morning as warmer, more humid air moves into New England.
Rainfall totals remain on track, with most areas receiving between one quarter and three quarters of an inch, while isolated locations could receive as much as 2 inches.
Forecast models indicate the rain should move out fairly quickly Friday morning, allowing for partial sunshine before an approaching cold front. If enough clearing develops, the atmosphere could become unstable enough to support strong to severe thunderstorms Friday afternoon.
Forecast guidance suggests atmospheric instability, technically called MLCAPE (Mixed Layer Convective Available Potential Energy), could reach 700 to 1200 joules per kilogram, along with approximately 50 knots of effective wind shear. These conditions may allow individual rotating thunderstorms, known as supercells, to develop as the cold front moves west to east across the region.
Some storms may split into multiple rotating cells and interact with one another, making the overall storm evolution more complicated. Current indications suggest the greatest severe weather potential will be across New Hampshire and western Maine.
Several machine learning and artificial intelligence forecast models continue to identify Friday as a day with severe weather potential. Large hail appears to be the primary threat if storms remain isolated. Damaging wind gusts are also possible with any stronger rotating thunderstorms.
**Key Message 3 Description**
The overall weather pattern changes very little through much of the extended forecast, with each day looking fairly similar.
A large area of high pressure in the upper atmosphere across the central United States will keep New England in a pattern favorable for daytime heating to trigger scattered afternoon showers and thunderstorms. National Blend of Models guidance continues to indicate isolated to scattered precipitation chances on most days, and this forecast remains reasonable.
This pattern should also keep the hottest air away from New England. While some guidance suggests middle to upper 80s near the coast, forecasters favor cooler temperatures, generally upper 70s along the coast with 80s farther inland.
By the middle of next week, the upper level ridge may gradually expand into New England, allowing temperatures to slowly increase. Stronger winds higher in the atmosphere could also support more organized thunderstorm activity. While it is far too early for details, some longer-range machine learning guidance suggests a low-end risk for severe thunderstorms by Wednesday.
Weather Summaries and Full Area Forecast Discussions - South (Edited)
Summary - Southern New England - Massachusetts/Northern CT/Rhode Island
Summary:
Dry weather will continue for most of today with temperatures reaching the upper 70s to middle 80s. A round of showers and a few thunderstorms is expected to arrive tonight, with the greatest risk for stronger to potentially severe thunderstorms developing Friday afternoon and evening. Conditions improve over the weekend, although a few showers remain possible Saturday, especially across southeastern Massachusetts, Cape Cod, and the Islands. Warmer, mainly dry weather is expected early next week.
Key Messages:
- Dry weather for much of today before the risk for scattered showers and a few thunderstorms returns tonight into Friday.
- Showers Saturday followed by a warming and drying trend that carries into next week.
What has changed since the last Forecast Update?
Confidence has increased that there is a greater risk for severe thunderstorms on Friday.
What this means for you
Today is the best opportunity for outdoor activities before wetter weather returns tonight. While thunderstorms overnight should remain below severe limits, Friday afternoon has a better chance for a few storms capable of producing damaging wind gusts. Stay aware of forecast updates if you have outdoor plans Friday. After a few showers Saturday, warmer and drier weather is expected to return for several days.

**What Has Changed**
Confidence has increased that there is a greater risk for severe thunderstorms on Friday.
**Key Messages**
* Dry weather for much of today before the risk for scattered showers and a few thunderstorms returns tonight into Friday.
* Showers Saturday followed by a warming and drying trend that carries into next week.
**Discussion**
**Key Message 1**
Dry weather continues through much of today as high pressure remains in control, extending the pleasant weather experienced yesterday. Afternoon temperatures will once again reach the upper 70s to middle 80s.
Weather conditions begin changing tonight and continue into Friday as a warm front, connected to an area of low pressure moving through southern Ontario into Quebec, crosses southern New England. A band of showers with embedded thunderstorms is expected to move from west to east overnight.
The risk of severe weather overnight remains very low because the atmosphere is expected to be relatively stable. Forecast guidance, including Convective Allowing Models, commonly referred to as CAMs, indicates there will be very little instability available overnight to support stronger storms. A few rumbles of thunder are possible across western Massachusetts, but the greater concern shifts to Friday afternoon and evening.
As the warm front passes, winds will turn more southerly and dew point temperatures, a measure of atmospheric moisture, will climb into the middle and upper 60s, making it feel noticeably more humid.
Forecast confidence has improved compared to previous model runs. Current guidance shows increasing atmospheric instability Friday afternoon while also maintaining strong wind shear, the change in wind speed and direction with height that helps thunderstorms organize and strengthen. Forecasts indicate around 1000 Joules per kilogram of Most Unstable Convective Available Potential Energy, or MUCAPE, across much of the region, with localized values approaching 1500 Joules per kilogram across western Massachusetts and Connecticut. Mixed Layer Convective Available Potential Energy, or MLCAPE, is expected to be nearly as high. At the same time, effective bulk shear is forecast between 40 and 50 knots.
This combination of increasing instability, strong wind shear, and the approaching cold front could support isolated to scattered severe thunderstorms Friday afternoon and evening. Southern New England remains under a Marginal Risk, Level 1 out of 5, for severe weather. Continue monitoring forecast updates as confidence in storm timing and intensity improves.
**Key Message 2**
Another area of low pressure is forecast to pass south of southern New England on Saturday. A few showers are most likely across the south coast, Cape Cod, and the Islands, but rainfall is not expected to be significant.
Once this system moves away, high pressure and an expanding upper level ridge are expected to bring a return to dry weather early next week. Temperatures will begin warming at the start of the work week and continue climbing into the middle of next week. Exactly how warm it becomes remains somewhat uncertain, but at this time, the highest risk for unusually hot temperatures appears to remain southwest of southern New England. Forecasters will continue to monitor how this develops over the coming days.
