the first sign of advancing autumn."

At this moment: 8/24 - 7:16 AM

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 regular schedule continues.

We had a thunderstorm pass through Peterborough, NH last night at about 11:30 PM that dropped torrential rain for a bit. There have been some light showers early this morning and areas of dense fog, but the overcast skies should turn sunny today.
We have a swirling low pressure area over the Great Lakes that will slowly track through Quebec the next couple of days. That will leave the atmosphere unstable with a chance of a pop up passing shower both Monday and Tuesday. The best chance is from central NH north into Maine.
In 1992 Hurricane Andrew came ashore as a category 5 hurricane in south Florida. See the History Panel.

A cold front moves through today, bringing a chance of thunderstorms, especially across northern areas, followed by gradually drier weather and returning sunshine. Tuesday stays seasonable, with another stretch of comfortable weather expected Wednesday and early Thursday. Rain chances increase Thursday into Friday as a more humid air mass moves back into the region. Early indications suggest Friday could bring the most widespread rain, with some potential for locally heavy downpours.

"Everybody complains about the weather, but nobody does anything about it."
You may not be familiar with this quote, which turns 129 years old today, but for a good 80 years or so, it was everywhere. And just about everyone who said it attributed it to the wrong person.
Now, if there’s any late 19th-century humorous quote wrongly attributed to an American, the American it is wrongly attributed to will probably be Mark Twain, as is the case with this one. That’s because Mr. Twain was considered the great wit of his day, and his sayings had a way of traveling farther and faster than anyone else's. If it was clever, the feeling seems to have been that it must have been Twain who said it.
Except, in this case, it wasn't. The line first showed up in print on this day in 1897, in an unsigned editorial in the Hartford Courant, and the man behind it was almost certainly Charles Dudley Warner, who was the paper's editor, a fine essayist in his own right and, as it happens, Twain's next-door neighbor and co-author.
But even more interesting, to my mind, at least, than the authorship of this once-ubiquitous line, is what its popularity tells us about how our relationship with weather has (and hasn't) changed over the last century-and-a-quarter. Because in 1897, the joke landed for a simple reason: weather was something that happened to you. You could complain, you could speculate, you could look at the sky and guess - and that was about it.
Fast-forward to today, when most of us carry pocket supercomputers with incredible apps that can tell us when the rain will start and when the storm is coming. Just a couple of generations later, our grasp of the weather would seem like magic to Dudley, or Twain, for that matter.
Yet our basic habit remains intact. Weather is still the universal icebreaker and default conversational topic. Charles Dudley Warner might be amazed that we can track a storm cell halfway across the globe, but he would certainly recognize the sight of us standing on the porch, looking up at the rain clouds - and complaining about them anyway.

Weather Summaries and Full Area Forecast Discussions - North (Edited)

Summary - Northern New England - New Hampshire and Maine

Summary:
A cold front moves through today, bringing a chance of thunderstorms, especially across northern areas, followed by gradually drier weather and returning sunshine. Tuesday stays seasonable, with another stretch of comfortable weather expected Wednesday and early Thursday. Rain chances increase Thursday into Friday as a more humid air mass moves back into the region. Early indications suggest Friday could bring the most widespread rain, with some potential for locally heavy downpours.

Key Messages:

 - A cold front gradually moves through during the day today as an upper level low remains in the Great Lakes region.
 - The next chance of widespread rain comes late in the week, bookended by periods of dry weather through midweek and over the weekend.

What has changed since the last Forecast Update?
Very little change to the going forecast early this morning. The fog should lift by around 9 AM.

What this means for you:
Expect a changeable day today, with showers and thunderstorms possible before conditions gradually become drier. Temperatures will reach the 70s to near 80 degrees. Tuesday will be comfortable but a stray shower cannot be ruled out. Wednesday and early Thursday look mainly dry, while rain chances increase later Thursday and Friday. Next weekend currently looks favorable for drier and cooler weather, although there is still some uncertainty.

**Area Forecast Discussion, National Weather Service Gray ME, 628 AM EDT
Mon Aug 24 2026**

**What has changed**


Very little change to the going forecast early this morning. The fog should lift by around 9 AM.

**Key Messages**

1. A cold front gradually moves through during the day today as an upper level low remains in the Great Lakes region.

2. The next chance of widespread rain comes late in the week, bookended by periods of dry weather through midweek and over the weekend.

**Discussion**

**Key Message 1**


A cold front extending from a cutoff low in the Great Lakes moves through during the daytime today. This brings a chance for a strong thunderstorm across northern areas near the Canadian border this afternoon before the front moves off to the northeast. Elsewhere, scattered showers and a thunderstorm are possible, but overall conditions should become drier through the day behind the front. Highs generally reach the 70s to near 80 degrees, with sunshine returning.

Despite the front passing, scattered showers and storms remain possible as the cutoff low in the Great Lakes takes a few more days to slowly move eastward through southern Canada. While the overall trend is drier, showers remain possible through Tuesday.

Cooler temperatures return tonight as the drier air mass moves in. Lows range from the mid 50s along the coast to the upper 40s through the northern valleys. A stray shower cannot be ruled out overnight. Seasonable temperatures return Tuesday, with highs mainly in the 70s to near 80 degrees.

Early morning fog, locally dense, is likely.

**Key Message 2**

The upper level low finally moves completely out of the region by Wednesday. Brief ridging from Wednesday into early Thursday should bring quiet weather, comfortable humidity levels and seasonable temperatures. As Thursday progresses, winds from the south return ahead of the next trough, bringing a more humid air mass back into the region.

A surface low closes off over Hudson Bay, sending a cold front through our region Friday night. Forecast guidance indicates a chance for precipitation Thursday afternoon and evening, primarily across interior areas away from the coast. There will be another chance for precipitation Friday with the actual cold front, which currently appears more widespread.

Nothing noteworthy is expected for rainfall at the moment, but long range models already show a 30 to 50 percent chance of rainfall exceeding one half inch. Forecast precipitation amounts are scattered, indicating that rainfall could be more concentrated around individual showers and thunderstorms rather than falling evenly across the region. Increasing moisture, with dew points reaching the upper 60s, will provide the fuel needed for locally heavy downpours.

**Next Weekend**

The first look at next weekend suggests it could be a pleasant one, with drying westerly winds behind the cold front bringing comfortable dew points in the 40s and 50s. There is still some uncertainty, however, as some forecast guidance suggests the cold front could stall near the Southern New England coast.

Weather Summaries and Full Area Forecast Discussions - South (Edited)

Summary - Southern New England - Massachusetts/Northern CT/Rhode Island

Summary:
A drier and more seasonable stretch of weather is expected across southern New England today through much of Wednesday, with comfortable temperatures returning to the upper 70s and lower 80s. Rain chances increase late Thursday into Friday as low pressure moves toward the region, but drier weather is expected to return for the weekend.

Key Messages:

 - Drier with more seasonable temperatures today through much of this week.
 - Rain chances return Thursday/Friday, though drier conditions look to return heading into the weekend.

What has changed since the last Forecast Update?
Marthas Vineyard has been added to the Rip Current Statement for today.

What this means for you
Areas of morning fog will burn off shortly after sunrise, followed by partly to mostly clear skies and some afternoon southwest wind gusts around 20 to 25 MPH. Temperatures will be much closer to normal today and remain seasonable through much of the week. Keep an eye on the forecast for Thursday and Friday, when showers are likely to return, with improving conditions expected by Saturday.

717 AM EDT Mon Aug 24 2026**

**What has changed**


Marthas Vineyard has been added to the Rip Current Statement for today.

**Key Messages**

* Drier with more seasonable temperatures today through much of this week.

* Rain chances return Thursday/Friday, though drier conditions look to return heading into the weekend.

**Discussion**

**Key Message 1, Drier with more seasonable temperatures today through much of this week**


Higher dewpoints, light winds, and wet surfaces have helped produce areas of fog this morning, especially in locations that typically experience fog more often. The fog should burn off shortly after sunrise.

A cold front associated with low pressure centered over eastern Ontario and western Quebec will continue moving east across New England this morning. Behind the front, clearer skies and breezy southwest winds will develop across southern New England. Occasional wind gusts around 20 to 25 MPH are possible this afternoon.

Temperatures will return to more seasonable levels today, with highs in the upper 70s and lower 80s. This general pattern should continue through at least Wednesday as high pressure, an area of sinking air that generally brings fair weather, slowly builds in behind the front.

**Key Message 2, Rain chances return Thursday/Friday, though drier conditions look to return heading into the weekend**

High pressure is expected to move offshore Thursday ahead of a shortwave, a smaller disturbance in the upper atmosphere, approaching from the Great Lakes.

Recent model runs show somewhat better agreement on the track of the associated low pressure system, although uncertainty remains. Low pressure is expected to develop over the Great Lakes and extend northward toward Hudson Bay along the leading edge of an upper level trough, an elongated area of lower pressure higher in the atmosphere.

This low pressure system is expected to move eastward through Canada, sending showers into New England. Current guidance continues to favor late Thursday into early Friday for rain to return to southern New England, with showers potentially continuing through Friday.

NAEFS guidance, the North American Ensemble Forecast System, continues to indicate higher than normal PWAT values during this period. PWAT, or precipitable water, represents the total amount of moisture available in the atmosphere for producing precipitation. The exact moisture levels and rainfall potential will likely change somewhat as the event gets closer.

Following the rain late in the work week, there are indications that high pressure will return heading into Saturday, bringing drier weather back to southern New England.
