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:
There will be NO Thursday, Weekend Outlook E-mail this week, 7/23. Otherwise, the daily schedule remains in place.
We really have a gorgeous weekend ahead. Bright sunny skies Friday and Saturday, mostly sunny Sunday. Average mid summer temps in the upper 70s and low 80s. Low humidity all the way through Sunday. What more could you ask for?
Quiet and comfortable weather settles into the region through the weekend as cooler, drier air moves in behind a cold front. Most locations will stay dry with seasonable temperatures, while coastal areas remain a little cooler because of afternoon ocean breezes. Early next week, a broad area of lower pressure is expected to develop across the Northeast, bringing increasing chances for scattered showers from Monday through the middle of next week.

Weather Summaries and Full Area Forecast Discussions - North (Edited)
Summary - Northern New England - New Hampshire and Maine
Summary:
Quiet and comfortable weather settles into the region through the weekend as cooler, drier air moves in behind a cold front. Most locations will stay dry with seasonable temperatures, while coastal areas remain a little cooler because of afternoon ocean breezes. Early next week, a broad area of lower pressure is expected to develop across the Northeast, bringing increasing chances for scattered showers from Monday through the middle of next week.
Key Messages:
- High pressure brings mostly dry weather and seasonable temperatures through the weekend.
- A trough of low pressure brings daily shower chances Monday through the middle of next week.
What has changed since the last Forecast Update?
No significant changes with this forecast update. Quiet weather is expected through the weekend.
What this means for you:
The next several days will be favorable for outdoor activities with mostly dry weather and comfortable humidity. Nights will be cool enough in many areas to open the windows, especially inland. By Monday, it will be worth keeping an eye on the forecast as shower chances gradually increase through the middle of next week, although it is still too early to determine the exact timing of any rainfall.

**What Has Changed**
No significant changes with this forecast update. Quiet weather is expected through the weekend.
**Key Messages**
1. High pressure brings mostly dry weather and seasonable temperatures through the weekend.
2. A trough of low pressure brings daily shower chances Monday through the middle of next week.
**Discussion**
**Key Message 1 Description**
Cooler and drier air continues to move into the region today behind a cold front that crossed the area last night. Afternoon high temperatures will range from the upper 60s across northern areas to near 80 degrees along the coast. Winds will blow steadily from the west northwest, while afternoon sea breezes are expected to develop along the coastline.
A broad area of high pressure centered over the Great Lakes will gradually move east through the weekend, providing generally fair weather. Daytime temperatures will mostly reach the 80s inland, while coastal communities remain somewhat cooler because of onshore winds from the ocean.
Clear skies, light winds, and dry air will create favorable conditions for **radiational cooling**, the process where heat escapes into the atmosphere after sunset. This will allow overnight low temperatures to fall into the 40s and 50s tonight and again Friday night.
**Key Message 2 Description**
Forecast guidance is in good agreement that a **trough**, an elongated area of lower atmospheric pressure that often supports clouds and unsettled weather, will deepen across the Northeast from Monday through the middle of next week.
While confidence is high that the overall weather pattern will become more unsettled, it remains difficult to determine the exact timing and location of individual weather systems moving through the trough.
Current forecast guidance indicates precipitation chances remain below 30 percent on Monday, then increase to around 50 percent on Tuesday and Wednesday.

Early next week, a more active weather pattern develops with periodic chances for scattered showers and thunderstorms as several weather disturbances move through the region.
Key Messages:
- Mainly dry with seasonable temperatures through the weekend.
- Unsettled weather for early to mid-week next week with periodic chances for scattered showers and thunderstorms.
What has changed since the last Forecast Update?

**Area Forecast Discussion, National Weather Service Boston/Norton MA**
**300 AM EDT Thursday, July 23, 2026**
**What Has Changed**
No significant changes to the forecast.
**Key Messages**
* Mainly dry with seasonable temperatures through the weekend.
* Unsettled weather for early to mid-week next week with periodic chances for scattered showers and thunderstorms.
**Discussion**
**Key Message 1, Mainly dry with seasonable temperatures through the weekend**
A few showers and a few weak thunderstorms remain possible over the coastal waters early this morning as a cold front moves offshore. By sunrise, the front should be east of the region, ending any remaining showers.
Behind the front, a weak upper level trough, an area of lower air pressure higher in the atmosphere, will bring cooler and drier air into southern New England. Temperatures about 2,500 feet above the ground are a few degrees cooler than yesterday, supporting afternoon highs mainly in the upper 70s to around 80 degrees today.
Humidity levels will also be noticeably lower, making it feel much more comfortable. High pressure building in from the west will keep winds light, with northwest winds inland and local sea breezes developing along the coast.
High pressure remains over the region Friday and continues through the weekend while the jet stream becomes more west to east, a pattern meteorologists call zonal flow. Weak sinking air, known as subsidence, will help keep skies mainly dry. Winds remain light, gradually becoming easterly over the weekend.
Temperatures about 2,500 feet above the ground will support afternoon highs in the low to mid 80s across most of southern New England, with somewhat cooler temperatures along the immediate coastline where sea breezes and onshore winds are expected.
By Sunday, high pressure shifts offshore as another upper level trough approaches from the west. Even so, the dry air already in place should limit most shower development during the day.
**Key Message 2, Unsettled weather for early to mid-week next week with periodic chances for scattered showers and thunderstorms**
The weather pattern becomes more active early next week as an upper level trough settles across the Northeast and several weather disturbances move through the flow.
Forecast guidance shows increasing moisture across the region, with precipitable water, the total amount of moisture available in the atmosphere, rising to slightly above normal levels. This will increase the chances for periodic scattered showers and thunderstorms from early next week through the middle of the week.
Temperatures are expected to remain seasonable, with afternoon highs generally in the low 80s.
