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! On October 10 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!

Expect a breezy Friday with occasional wind gusts reaching 30 mph, but Saturday should offer a welcome stretch of sunshine. If you have sensitive plants outdoors, be prepared for possible frost Saturday night, even in some coastal communities. Rain late Sunday into Monday looks relatively light for most areas, although amounts will vary across the region. Tuesday may bring another round of showers before cooler, drier weather settles in for the rest of the week.

We finally have our first hurricane of the season: Isaias 
It appears that the heaviest rainfall from the remnants of this system will only affect the south coast of New England as the system zips past.

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:
New England will see gusty winds and a few isolated showers today, followed by sunny and pleasant weather Saturday. However, temperatures will drop sharply Saturday night, bringing the potential for frost across much of the interior and even along the coast. Rain is expected to return late Sunday into Monday as moisture from the remnants of Tropical Cyclone Isaias moves into the region. Another cold front may bring additional showers Tuesday, followed by cooler and mainly dry weather for the middle to latter part of next week.

Key Messages:

 - West-northwest winds will gust between 20 and 30 mph today, with a few isolated showers possible. High pressure will bring fair weather Saturday, followed by the potential for frost along the coast Saturday night.
 - Rain chances increase late Sunday and continue into Monday as the remnants of Isaias and an approaching cold front move across the Northeast. Additional showers are possible with another cold front on Tuesday.

What has changed since the last Forecast Update?
No significant changes have been made to the forecast in this early Friday morning update.

What this means for you:
Expect a breezy Friday with occasional wind gusts reaching 30 mph, but Saturday should offer a welcome stretch of sunshine.

Key Message 1: Gusty Winds Today, Sunshine Saturday, and Frost Potential Saturday Night


Unsettled air moving through the upper atmosphere will continue to influence the region today. A trough of lower atmospheric pressure near the surface will cross the area early this afternoon, bringing a chance of isolated showers. Much of the region should still see partly to mostly sunny skies.

Forecast guidance has backed off somewhat on the expected wind strength, but winds are still expected to become gusty as daytime heating allows stronger winds higher in the atmosphere to mix down to the surface. Winds around 30 to 35 knots above the ground could translate into surface gusts near 30 mph, with occasional stronger gusts possible. Showers that persist for a time could also produce locally higher wind gusts.

High pressure will build into the region Friday night and Saturday, allowing winds to ease Friday night. Saturday should be pleasant, with sunny skies and afternoon high temperatures ranging from the upper 40s near the Canadian border to the lower 60s south of the mountains.

By Saturday night, the center of high pressure will move into the Gulf of Maine. Clear skies and light winds will create favorable conditions for radiational cooling, which occurs when the ground loses heat after sunset. Temperatures are expected to fall below freezing across much of the interior, with frost possible all the way to the coast. Gardeners should take precautions to protect sensitive plants.

Key Message 2: Rain Returns Late Sunday, With More Showers Possible Tuesday

The latest forecast guidance continues to indicate that leftover moisture from Tropical Cyclone Isaias will bring a period of rain to the region late Sunday into Monday morning. Rainfall amounts are expected to be relatively light, ranging from around one-half inch across portions of southern New Hampshire and southwestern Maine to less than one-tenth of an inch across northern areas.

Some partial clearing is likely later Monday, and temperatures should be warmer than average, with highs reaching the upper 60s to lower 70s south of the mountains.

After a mild Monday night, a cold front and an associated area of low pressure will move southward from the north on Tuesday. This system will bring another round of showers and gusty southwest winds. Winds will turn northwest Tuesday night as cold air moves into the region behind the front. This process, known as cold air advection, simply means that winds are transporting colder air into the area.

Cooler temperatures are expected from the middle to the latter part of next week, with mainly dry conditions prevailing.

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

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

Summary:
Southern New England will enjoy cool, dry, and mostly sunny weather through Sunday morning, with daytime highs in the 60s and a chilly start to Saturday, especially in typically colder locations. Rain is expected to arrive Sunday afternoon or evening, continue overnight, and move offshore by Monday morning. Another chance for rain develops around Tuesday or Wednesday, followed by drier weather toward Thursday.

Key Messages:

 - Cool, quiet, and dry weather will continue through the first half of Sunday. Expect highs in the 60s, with a chilly start Saturday morning, especially in the typical cold spots.
 - The next quick-moving round of rain arrives Sunday afternoon and evening, continues overnight, and exits by Monday morning.
 - Another quick round of rain is possible around the middle of next week, followed by a return to dry weather by Thursday.

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

What this means for you
Plan on a pleasant start to the holiday weekend, although breezy conditions are expected today and Saturday morning could feel chilly. Keep an umbrella handy for Sunday afternoon through early Monday, especially across western areas where rain is more likely. Some locations, particularly near the south coast, could receive an inch or more of rain, but the exact amounts remain uncertain. No significant flooding or damaging wind threats are currently expected with this system.

What Has Changed


No significant changes have been made to the forecast.

Key Messages

Cool, quiet, and dry weather will continue through the first half of Sunday. Expect highs in the 60s, with a chilly start Saturday morning, especially in the typical cold spots.

The next quick-moving round of rain arrives Sunday afternoon and evening, continues overnight, and exits by Monday morning.

Another quick round of rain is possible around the middle of next week, followed by a return to dry weather by Thursday.

Discussion

Key Message 1: Cool, Quiet, and Dry Weather Through Sunday Morning


A broad upper-level trough, an elongated area of lower atmospheric pressure, will slowly move across the region today as high pressure approaches from the west. This setup will bring gusty northwest winds across southern New England, with wind speeds increasing several thousand feet above the ground and mixing down to the surface. As a result, today could feel similar to Thursday, with breezy conditions despite mostly sunny skies and temperatures reaching the middle 60s.

High pressure will continue moving east and settle over the region by Saturday afternoon. This should bring a beautiful start to the holiday weekend, with sunshine, light winds, and highs in the 60s.

The main concern for Saturday night is how quickly the winds diminish. If winds become light or calm, the ground can lose heat efficiently after sunset through a process called radiational cooling. This could lead to a chilly Saturday morning, particularly in sheltered inland valleys and other typical cold spots. Forecast guidance supports these cooler morning temperatures.

Key Message 2: Rain Arrives Sunday Afternoon and Exits Monday Morning

Compared with forecasts from 24 hours ago, the next round of rain is now expected to arrive slightly sooner and depart more quickly.

Forecast models generally agree that moisture remaining from the former Hurricane Isaias will be carried eastward by a weather system moving through the northern United States. The rain will move across the Mid-Atlantic region and then offshore. There is still some disagreement about how far north the rain will reach, but southern New England is expected to be within the area receiving precipitation.

Western parts of the region are more likely to see showers Sunday afternoon and evening. Forecast ensemble guidance, which combines multiple model simulations to estimate the likelihood of different outcomes, indicates an 80 to 90 percent chance of at least 0.01 inches of rain across western Massachusetts and Connecticut by 8 PM Sunday. Far eastern Massachusetts has lower probabilities, around 40 to 50 percent.

By Monday morning, there is good agreement that the rain will have moved offshore, making this primarily an overnight rainfall event.

Overall, this appears to be a fairly typical rain-producing system for southern New England, without a significant threat of flooding or damaging winds. Forecast guidance suggests around half an inch of rain across northern Massachusetts, increasing to more than 1 inch along the south shore, where atmospheric conditions may be more favorable for heavier precipitation.

There is still uncertainty about where the heaviest rain will fall. One group of forecast models, known as the European ensemble system, has increased the probability of more than 1 inch of rain to as high as 40 to 50 percent along the immediate south coast. Meanwhile, the American Global Ensemble Forecast System indicates virtually no chance of exceeding 1 inch. These differences highlight the remaining uncertainty in both rainfall totals and the location of the heaviest precipitation.

Key Message 3: Another Chance for Rain Around Midweek

A brief period of high pressure should bring a break in the unsettled weather Monday into Tuesday. Another frontal system is then expected to move through, potentially bringing another round of rain.

Confidence remains low regarding the exact timing and location of this next system. Its development and track may also depend on how the weekend weather system evolves. For now, unsettled weather appears possible late Tuesday or Wednesday, with drier conditions expected to return by Thursday.
