A mostly sunny, warmer day, is expected today with highs in the upper 70s to low 80s. There is a slight chance for a passing shower or thunderstorm this afternoon in the mountains. A sunny day, again Thursday, but clouds will be on the increase as the next system begins to approch the region. Showers return Thursday night through Friday morning. The weekend is looking mostly dry, but a chance for showers does exist. I am working on that forecast so stay tuned.
I have begun displaying travel maps for the Independence Day holiday. You can find them in the bottom NEWs Section.
Mainly dry weather is expected through Thursday, although a few afternoon showers and thunderstorms may develop in the mountains both days. A more widespread round of rain arrives Thursday night. Another opportunity for thunderstorms comes on Friday as a low pressure system moves through eastern Canada. Some storms could become strong, especially across New Hampshire and southwestern Maine. Warmer weather follows into the weekend and early next week, with temperatures climbing back into the 80s and a few lower 90s possible in the warmest inland locations.

From the Weather Channel:
The Sahara Desert. Death Valley and the American Southwest. The Middle East. What do those three areas have in common? They will be pretty much the only spots on the entire planet that will be hotter than the hottest parts of France this week. And it's not just France: Much of Europe is sweltering under a deadly heat dome that is causing authorities to warn locals and visitors of the dangerous conditions awaiting them. In France, where temperatures are climbing above 104 degrees (40 degrees Celsius) and nighttime lows are refusing to drop below a stifling 68, this isn't your typical summer scorcher.
French meteorologists are drawing comparisons to the catastrophic August 2003 heat wave that claimed an estimated 15,000 lives across the country. More than half of France's regions are under the highest "red alert" heat warning, and the human toll is mounting: Two young children died after becoming trapped in a family car, while multiple drowning deaths have been reported as residents seek relief in dangerous waterways.
Britain, meanwhile, has issued only its second-ever heat-health alert, warning of risk to life even for healthy people as temperatures could shatter the country's June record by reaching 102 degrees, easily surpassing the monthly record of 95, which was set all the way back in 1957, then tied in 1976. The extreme heat follows Britain's hottest May on record, with officials warning that humidity will make conditions even more dangerous through "tropical nights" where temperatures refuse to drop below 68.

Summary:
Mainly dry weather is expected through Thursday, although a few afternoon showers and thunderstorms may develop in the mountains both days. A more widespread round of rain arrives Thursday night. Another opportunity for thunderstorms comes on Friday as a low pressure system moves through eastern Canada. Some storms could become strong, especially across New Hampshire and southwestern Maine. Warmer weather follows into the weekend and early next week, with temperatures climbing back into the 80s and a few lower 90s possible in the warmest inland locations.
Key Messages:
- It will be mainly dry today and Thursday, but a few mountain showers and storms will be possible each afternoon. The next chance for widespread rain moves in Thursday night.
- Next chance of thunderstorms arrives Friday with a low pressure system moving through the St. Lawrence Valley. This will be followed by fair and warmer weather.
What has changed since the last Forecast Update?
No major changes were needed this morning as the forecast remains on track.
What this means for you:
Most communities will enjoy dry weather today and Thursday with seasonable temperatures. If you are in the mountains, keep an eye out for a few afternoon showers or thunderstorms. Thursday night brings the next widespread chance for rain. Friday will be the day to watch for stronger thunderstorms, particularly if enough sunshine develops after any morning rain. The weekend looks warmer with only isolated afternoon showers or thunderstorms possible.

Area Forecast Discussion
National Weather Service Gray ME
603 AM EDT Wednesday June 24 2026
**What Has Changed**
No major changes were needed this morning as the forecast remains on track. Routine updates were made to the short term forecast grids and aviation forecast.
**Key Messages**
1. It will be mainly dry today and Thursday, but a few mountain showers and storms will be possible each afternoon. The next chance for widespread rain moves in Thursday night.
2. Next chance of thunderstorms arrives Friday with a low pressure system moving through the St. Lawrence Valley. This will be followed by fair and warmer weather.
**Discussion**
**Key Message 1 Description**
An upper level low pressure system will continue spinning over southeastern Quebec today before drifting east northeast into the Canadian Maritimes tonight and Thursday morning. This weather pattern will help trigger some afternoon showers and thunderstorms today.
High resolution forecast models, known as CAMs (Convection Allowing Models), suggest most storms will develop in Canada before moving south into northern New Hampshire and northwestern Maine, where they are expected to weaken. Forecast soundings from the RAP model indicate atmospheric instability, measured by MUCAPE (Most Unstable Convective Available Potential Energy), could reach around 1000 J/kg. In plain terms, that is enough energy to support thunderstorms. Wind shear, which measures changes in wind speed and direction with height, will be marginal, but a few stronger storms could still produce small hail and gusty winds.
Any showers and storms should fade quickly after sunset as daytime heating is lost.
A ridge of high pressure aloft will move across the region Thursday ahead of the next weather system. A weak disturbance may spark another round of scattered afternoon showers and thunderstorms, and some of these could move beyond the mountains. Increasing warm air moving into the region ahead of the next storm system will then bring a broader chance of rain Thursday evening and overnight.
High temperatures today will range from the middle and upper 60s across northern areas to the middle and upper 70s farther south. A few lower 80s are possible in southeastern New Hampshire and along the coast. Thursday will be slightly warmer across the entire region.
**Key Message 2 Description**
A warm front is expected to slowly move north through the area Friday morning. The biggest forecast challenge will be determining how much sunshine develops after any morning rain and cloud cover.
This system is not expected to be nearly as strong or unusual as last Thursdays storm. However, the combination of atmospheric instability and wind shear may still become favorable for strong thunderstorms, especially across New Hampshire and southwestern Maine.
Several forecast tools support a faster departure of morning rain. These include the ECMWF EFI (European Centre for Medium Range Weather Forecasts Extreme Forecast Index), machine learning based thunderstorm guidance, and overall weather model trends.
Forecast soundings indicate there should be enough wind shear to organize thunderstorms. However, the wind profile does not strongly favor tornado development. While an isolated tornado cannot be completely ruled out, the primary threats appear to be damaging wind gusts and hail. The overall storm threat will depend heavily on whether enough sunshine develops to build instability during the afternoon.
Thunderstorm activity should diminish quickly Friday evening as daytime heating fades.
Beyond Fridays system, high pressure will attempt to build into the region. However, forecast guidance increasingly suggests a large ridge of high pressure will strengthen across the central United States. This setup may keep the atmosphere somewhat unsettled locally through at least Monday.
As a result, isolated to scattered afternoon showers and thunderstorms remain possible each day, especially during the warmest part of the afternoon. While conditions will not be completely dry, widespread rainfall is not expected at this time.
Temperatures will gradually trend warmer as the ridge expands eastward. Highs should return well into the 80s by early next week, with a few lower 90s possible in the typically warmer locations of the Merrimack Valley.
Weather Summaries and Full Area Forecast Discussions - South (Edited)
Summary - Southern New England - Massachusetts/Northern CT/Rhode Island
Summary:
Quiet and comfortable weather is expected across southern New England through most of Thursday with sunshine, lower humidity, and temperatures mainly in the upper 70s to lower 80s. The next opportunity for showers and thunderstorms arrives Thursday night and continues into Friday as a warm front and later a cold front move through the region. A few stronger storms are possible Friday evening, but confidence in any severe weather threat remains low at this time. Some showers may linger into Saturday before drier weather returns for much of the weekend and early next week, along with a gradual warming trend.
Key Messages:
- Dry and seasonable today through much of the day Thursday.
- Risk for scattered showers and a few thunderstorms returns Thursday evening and night into Friday.
- Showers may linger into Saturday. Otherwise, dry weather expected through much of the weekend into the start of next week.
What has changed since the last Forecast Update?
No significant changes to the forecast at this time. Latest trends remain on track.
What this means for you
If you have outdoor plans today or Thursday, weather conditions look favorable with seasonable temperatures and dry conditions. Keep an eye on the forecast for Thursday night and Friday, when showers and thunderstorms become more likely. While widespread severe weather is not expected at this time, forecasters are watching the potential for a few stronger storms Friday evening. The weekend is trending mainly dry after any lingering showers early Saturday.

National Weather Service Boston/Norton MA
657 AM EDT Wednesday, June 24, 2026
**What Has Changed**
No significant changes to the forecast at this time. Latest trends remain on track.
**Key Messages**
* Dry and seasonable today through much of the day Thursday.
* Risk for scattered showers and a few thunderstorms returns Thursday evening and night into Friday.
* Showers may linger into Saturday. Otherwise, dry weather expected through much of the weekend into the start of next week.
**Discussion**
**Key Message 1, Dry and seasonable today through much of the day Thursday**
Rain has continued to move farther offshore from Cape Cod and the Islands early this morning and will continue to do so through sunrise. Areas of patchy fog, enhanced by recent rainfall, will gradually dissipate as winds increase and sunshine develops.
The weather pattern will turn sunnier and drier today as the disturbance responsible for the recent rain moves away and west winds increase. High temperatures will generally reach the upper 70s to lower 80s. Dry weather is expected to continue through much of Thursday as high pressure remains in control across much of the eastern United States and extends into the Northeast.
**Key Message 2, Risk for scattered showers and a few thunderstorms returns Thursday evening and night into Friday**
The next chance for rain and thunderstorms arrives Thursday night as an upper-level disturbance, known as a shortwave, approaches southern New England. At the surface, a low pressure system moving through the Great Lakes into southern Ontario will push a warm front toward the region.
Showers will become more numerous Thursday night, and a few thunderstorms may develop, especially across western Massachusetts. The thunderstorm risk decreases farther east toward eastern Massachusetts and Rhode Island.
The risk for severe weather appears low Friday morning. However, another round of showers and thunderstorms may develop Friday afternoon and evening ahead of an approaching cold front. Forecast guidance continues to show considerable uncertainty regarding how much atmospheric instability will be available to fuel stronger storms. Some forecast models suggest favorable wind shear conditions, which can help thunderstorms organize and strengthen.
At this point, the approaching cold front is expected to provide enough lift to generate showers and thunderstorms. Whether any storms become severe remains uncertain because confidence is still low regarding the overlap of instability and wind shear. Forecasters will continue to monitor this potential over the coming days.
**Key Message 3, Showers may linger into Saturday. Otherwise, dry weather expected through much of the weekend into the start of next week**
A few lingering showers may still be around Saturday morning. Another area of low pressure is forecast to pass south of southern New England, although there remains a chance that some showers could brush the South Coast during the daytime hours.
Beyond that, drier weather is expected to return through the remainder of the weekend and into early next week as high pressure associated with a strengthening upper-level ridge builds into the region.
Temperatures are also expected to trend warmer as the new work week begins, with the warming continuing into the middle of next week. However, there is still uncertainty regarding exactly how warm temperatures may become.
