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: 

I need a forecasting break! Even I get tired of the weather! Starting on October. 11 I will update the daily forecast for the next seven days. There will be no site updates through October 16. Site updates will begin again on October. 17 with minimal breaks through the winter months. During this break period my weather instruments will be offline for annual maintenance. Thank you!

We had a couple of brief showers this morning, and that should be it for the day.
Expect a few showers this morning, then a breezy and warmer afternoon with a chance of an isolated thunderstorm inland. Friday will be noticeably cooler and windy, with gusts around 30 mph. Saturday should be mostly sunny and pleasant. Rain chances increase late Sunday into Monday, although the exact timing and amount remain uncertain. Another round of showers is possible Tuesday night, followed by colder weather that could bring some snow to the higher elevations and areas near the Canadian border.

We finally have our first hurricane of the season: Isaias

From the Weather Channel:
Good Morning. Isaias has become the first Atlantic hurricane of 2026, ending an exceptionally quiet start to the season as it heads toward the northern Gulf Coast. Hurricane, tropical storm and storm surge warnings are now in effect from southeastern Louisiana to Florida.

Isaias is currently a Category 1 hurricane more than 400 miles south-southwest of New Orleans. It's moving east-northeast, and is forecast to strengthen rapidly over the central Gulf, potentially becoming a Category 2 hurricane by tonight.

We expect the storm to make landfall late Friday or early Saturday, most likely somewhere between the Mississippi Gulf Coast and the western Florida Panhandle. But those of you in the South shouldn't focus only on the center of the forecast cone: Isaias's impacts will extend far beyond the exact point where its eye crosses the coast, especially along and east of its track (aka the "dirty side" of the storm).
Life-threatening storm surge, damaging winds and isolated tornadoes are possible from southeastern Louisiana through the Florida Panhandle. Strong winds could begin as early as midday Friday, bringing down trees and power lines and potentially causing outages that could last for hours or several days. Isaias could also produce 3 to 7 inches of rain across a broad area, with localized totals approaching 10 inches near the Gulf Coast. Its heavy rain will then spread inland across the Southeast, Appalachians and parts of the Ohio Valley and mid-Atlantic this weekend, creating a risk of flash flooding far away from the coast.
If you're in southeastern Louisiana, southern Mississippi, Alabama or the Florida Panhandle, right now is the time to be preparing for possible evacuations and prolonged power outages. Those farther inland should also prepare for flooding, and remember never to drive onto a water-covered road. As the National Weather Service reminds us, "turn around, don’t drown."

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

Summary - Northern New England - New Hampshire and Maine

Summary:
A cold front will bring a few showers this morning, followed by breezy west winds today and gusty west northwest winds Friday. Fair weather is expected Saturday before increasing rain chances arrive late Sunday into Columbus Day as moisture from the remnants of Tropical Cyclone Isaias interacts with another frontal system. Another cold front will cross Tuesday night, bringing renewed shower chances and a cooler pattern for the middle of next week.

Key Messages:

 - A cold front will bring chances for showers this morning, followed by breezy west winds.
 - Gusty west northwest winds Friday will reach 20 to 30 mph, followed by high pressure and fair weather Saturday.
 - Moisture from the remnants of Tropical Cyclone Isaias, combined with an approaching frontal boundary to the west, will bring increasing chances for rainfall late Sunday into Columbus Day. A cold front will cross Tuesday night, bringing another chance for showers along with cooler temperatures for the middle of next week.

Thu Oct 8 2026**

**WHAT HAS CHANGED**


No major changes were made with this forecast update early Thursday morning.

**KEY MESSAGES**

1. A cold front will bring chances for showers this morning, followed by breezy west winds.

2. Gusty west northwest winds Friday will reach 20 to 30 mph, followed by high pressure and fair weather Saturday.

3. Moisture from the remnants of Tropical Cyclone Isaias, combined with an approaching frontal boundary to the west, will bring increasing chances for rainfall late Sunday into Columbus Day. A cold front will cross Tuesday night, bringing another chance for showers along with cooler temperatures for the middle of next week.

**DISCUSSION**

**KEY MESSAGE 1**


A cold front will push offshore this morning as a disturbance moves through the upper atmosphere. A broken line of showers, with perhaps a rumble of thunder, will move southeast of the mountains through daybreak and then offshore between 7 AM and 9 AM. Precipitation will be light, generally less than a tenth of an inch.

Winds will turn westerly behind the front and increase late this morning into the afternoon, with gusts approaching 25 to 30 mph. Stronger mixing of the atmosphere, combined with winds descending from higher terrain, will allow temperatures to reach the upper 60s to lower 70s south of the mountains.

Some atmospheric instability will develop with afternoon heating. MU CAPE, or most unstable convective available potential energy, is expected to approach 500 J/kg. This is a measure of how much energy is available in the atmosphere to support thunderstorms. Most short range weather models suggest an isolated thunderstorm could develop across the interior this afternoon.

Gusty winds should diminish this evening as the atmosphere becomes more stable after sunset.

**KEY MESSAGE 2**

The unsettled upper level pattern will continue Friday as the difference in air pressure strengthens between incoming high pressure and a strengthening area of low pressure over Atlantic Canada.

A surface trough, which is an elongated area of relatively low pressure, will cross the region and bring chances for showers and perhaps a thunderstorm, mainly across northern areas during the afternoon.

The main story Friday will be gusty west northwest winds from mid morning through the afternoon. Forecast profiles show stronger winds mixing down from higher in the atmosphere, with winds near the top of the mixed layer around 40 knots. This should produce persistent surface gusts up to 30 mph, with occasional stronger gusts possible.

Otherwise, skies will be mostly sunny south of the mountains. High temperatures will range from near 50 degrees across the north to the middle 60s along the coast and across southern New Hampshire.

**KEY MESSAGE 3**

The latest forecast guidance continues to show that moisture from the remnants of Tropical Cyclone Isaias, combined with an approaching front to the west, will bring increasing chances for rainfall late Sunday into Columbus Day.

There is still considerable uncertainty regarding the exact timing and amount of rainfall. Some forecast guidance shows meaningful rainfall across much of the region, while other guidance keeps most of the rain to the south.

Latest NAEFS guidance, the North American Ensemble Forecast System, shows atmospheric moisture increasing substantially by Monday morning. Precipitable water values, which measure the total amount of moisture available in the atmosphere, could reach around 1.50 inches, about two standard deviations above normal.

Despite the high moisture levels, the latest artificial intelligence and ensemble forecasts show a generally 25 percent or lower chance of at least 0.50 inches of precipitation over a 24 hour period, with the highest probabilities across southern areas. Any rainfall that does occur therefore appears likely to be manageable and beneficial.

Any lingering rain should end Monday evening, followed by mainly dry conditions through the first half of Tuesday. Another cold front and trough of low pressure are expected to cross the region late Tuesday into Tuesday night, bringing renewed chances for showers.

Falling temperatures higher in the atmosphere may allow some of the precipitation to fall as snow across the higher terrain and toward the Canadian border as overnight temperatures fall into the 30s to near 40 degrees. Colder temperatures are expected to follow behind this front for the middle to end of next week.

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

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

Summary:
Mostly dry weather is expected across southern New England through Sunday, with only a few scattered showers today. Temperatures will be warmer today before settling into the 60s Friday through Sunday, with some areas potentially seeing frost Saturday morning. Another round of rain is expected Sunday evening and Sunday night, but the system should move through quickly, limiting rainfall amounts and reducing the risk of flooding or damaging winds.

Key Messages:

 - Mostly dry weather prevails through Sunday, with the exception of a few scattered showers Thursday. Highs will consistently be in the 60s after a warmer Thursday. Saturday morning may be frosty in spots.
 - The next quick moving round of rain comes Sunday evening and overnight, exiting sometime on Monday, although confidence in the exact timing is low. No flooding or damaging winds are expected at this time.

What has changed since the last Forecast Update?
No significant changes to the forecast.

What this means for you
Most of the region will have dry weather for the next several days after a few showers today. Cooler air will arrive behind a cold front, with comfortable afternoons in the 60s and chilly nights. Some normally colder locations could see frost early Saturday morning. Rain returns Sunday evening and overnight, but current indications suggest a fairly routine rainfall event rather than a significant storm.

**What has Changed**


No significant changes to the forecast.

**Key Messages**

Mostly dry weather prevails through Sunday, with the exception of a few scattered showers Thursday. Highs will consistently be in the 60s after a warmer Thursday. Saturday morning may be frosty in spots.

The next quick moving round of rain comes Sunday evening and overnight, exiting sometime on Monday, although confidence in the exact timing is low. No flooding or damaging winds are expected at this time.

**Discussion**

**Key Message 1, Mostly Dry Weather Through Sunday**


High pressure, an area of sinking air that generally brings fair weather, will dominate after today. A pre-frontal trough, a narrow zone of lower pressure ahead of a cold front, along with a moisture-starved surface cold front will move through this morning.

There will be just enough moisture for a few isolated showers, mainly during the early morning across western areas and during the late morning into early afternoon farther east. Only a slight chance of showers is expected, and many locations will remain completely dry.

Clouds will increase as the front moves through, but skies should clear during the afternoon and overnight. As a large area of high pressure builds across the region, cool and dry weather will continue through much of Sunday.

Cool northwest winds around the high pressure system will bring colder air into the region. Temperatures several thousand feet above the ground are expected to drop, leading afternoon highs to struggle to get out of the low to mid 60s Friday and Saturday. Temperatures will moderate Sunday as winds turn more southerly behind the departing high pressure system.

**Key Message 2, Rain Returns Sunday Night**

Confidence remains moderate to high that the next round of rain will arrive late Sunday or Sunday night. The system is expected to move through fairly quickly as the remnants of Tropical Storm Isaias are absorbed into a larger upper-level trough, an elongated area of lower pressure in the atmosphere. The system should move eastward rather quickly before strengthening over the Gulf of Maine.

There will be a good supply of moisture, especially across southern parts of the region, but the quick movement of the system should limit rainfall amounts and reduce the potential for flooding. Overall, this looks like a fairly typical rainmaker for the region, without significant concerns for flooding or damaging winds.

Current forecast guidance generally shows rainfall amounts of a quarter inch or less across northern Massachusetts, increasing to around 1.25 inches along the south coast where the storm will have better access to moisture and stronger atmospheric forcing. Ensemble forecasts, which combine many individual forecast model runs to estimate the range of possible outcomes, show essentially no chance of more than 1 inch of rain across most areas, with only a 10 to 20 percent chance along the immediate south coast.
