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 & General Messages: 

Updated : On Friday, 10/23, there will be a morning update, but no evening update. On Saturday 10/24, there will NOT be a morning update, but there will be an evening update. On Sunday, 10/25 I will return to the regular schedule.

For Northern NE:
Expect several more days of generally dry weather across northern New England, although clouds will increase at times as a storm passes offshore. Nights will remain chilly, with temperatures dipping into the 20s and 30s in many locations. After another cool stretch late in the week, a warming trend will bring more comfortable afternoon temperatures for the weekend and early next week.

For Southern NE:
A distant Nor’easter will continue to generate rough seas, hazardous marine conditions, and gusty northeast winds across southern New England through Thursday. While most areas remain dry, southeastern New England could see a few light rain showers Wednesday and Thursday. Sunshine will prevail inland, with seasonably mild afternoons and cool nights. A prolonged stretch of dry weather is expected from Friday into early next week, with cooler temperatures Friday followed by a gradual warming trend through the weekend and into Monday.

Good Morning.
How do you know when it’s time to carve your pumpkin? Now that we’re under the two-week mark until Halloween, it’s a pretty natural question to ask. And I think that, for many of us, the answer is that we carve our pumpkins when we have free time, quite possibly on the weekend before Halloween. Which, it turns out, can be fine, or it can be a recipe for scary (but not in a good way) jack-o-lanterns.
Here’s the deal: Pumpkins are extremely hardy when they are intact. But once we start gouging holes in them and ripping out their innards, a whole new chemistry starts taking place. As the moist inner walls of pumpkin flesh get exposed to the elements, a lifespan of months gets reduced to just a few days. And how fast that happens comes down to the weather.
In cool, crisp autumn air, bacteria and mold move slowly, and a carved pumpkin can hold up for five to seven days (up to 10 in ideal conditions). But when it's warm and humid, with temperatures in the 60s and 70s or higher, pumpkins can soften and grow mold in a hurry. If that's your forecast, wait until a day or two before Halloween to carve, or bring your pumpkin indoors during the warmest part of the day.
Rain and freezing temperatures are the other things to watch. Heavy rain or dew can make the bottom and cut edges rot quickly, and a hard freeze can turn the flesh to mush once it thaws. The solution? After you’ve carved your masterpiece, keep an eye on the hourly forecast, and bring the pumpkin in for the night when either rain or freezing temps threaten.
Finally, if you really want to take care of your jack-o-lantern, here are a couple of pro-level tricks you can try. 1: Sanitize by wiping the inside and cutting the pumpkin’s edges with a diluted bleach-and-water solution to kill mold spores. 2: Seal the edges by rubbing vegetable oil or petroleum jelly on the cuts to lock in the pumpkin’s natural moisture. 3: Instead of a candle, which will dry out and cook the inside of the pumpkin, try using a battery-operated LED tea light instead.
Good luck, and may your pumpkin look fresh and perfect on its big night!

Key Messages

Discussion

Key Message 1: High Pressure Keeps Northern New England Dry


High pressure will keep northern New England dry through the end of the week and the weekend. Meanwhile, an ocean storm passing offshore will bring additional cloud cover to parts of the region this week, but significant precipitation is not expected.

Another cool night is ahead, with low temperatures falling into the 20s to middle 30s. Coastal areas will generally be milder, as occasional northerly breezes help mix the air and prevent temperatures from dropping as much.

An atmospheric inversion, a layer where temperatures increase with height rather than decrease, is expected to develop around 925 millibars, roughly 2,500 feet above sea level, on Wednesday. This will help keep temperatures cooler than they were today. High clouds will also spread inland from the coast as the offshore storm moves closer.

Midweek Through Friday

Temperatures will climb a few more degrees ahead of a weak cold front on Thursday before turning cooler again on Friday. The offshore ocean storm will make its closest approach Wednesday night into Thursday before moving toward the Canadian Maritimes.

Behind the departing storm, a fresh push of colder Canadian air will spread across the region. This will bring widespread low temperatures in the 20s Friday night, setting up another chilly night for much of northern New England.

Weekend and Early Next Week

The broad area of high pressure will gradually drift southward from late this week through the weekend. As the center of high pressure settles south of New England, temperatures will begin to moderate, bringing a warming trend that continues into early next week.

Dry conditions are expected to persist through the weekend. Afternoon highs should climb back into the 60s by Sunday, with some locations potentially reaching the lower 70s on Monday.

A weak cold front may approach by Tuesday of next week, but current expectations suggest that it will bring little, if any, precipitation.

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

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

Summary:
A distant Nor’easter will continue to generate rough seas, hazardous marine conditions, and gusty northeast winds across southern New England through Thursday. While most areas remain dry, southeastern New England could see a few light rain showers Wednesday and Thursday. Sunshine will prevail inland, with seasonably mild afternoons and cool nights. A prolonged stretch of dry weather is expected from Friday into early next week, with cooler temperatures Friday followed by a gradual warming trend through the weekend and into Monday.

Key Messages:

 - A distant Nor’easter is bringing hazardous marine conditions, with gusty northeast winds over land through Thursday. Aside from a few light rain showers Wednesday in southeastern New England, dry weather will prevail.
 - A prolonged stretch of dry weather is expected from Friday into early next week, except for a brief chance of showers over the eastern coastal waters Friday morning. Friday will be cooler, followed by moderating temperatures into early next week.

What has changed since the last Forecast Update?
Marine headlines, including gale warnings and small craft advisories, have been extended through Wednesday night. Gusty northeast winds and rough seas will continue. Otherwise, there are no significant changes to the forecast.

What this means for you
Expect breezy to gusty northeast winds through Thursday, especially across coastal areas, Cape Cod, and Nantucket, where gusts could reach 35 to 40 mph. Boaters should prepare for rough seas and potentially hazardous conditions, while some east-facing beaches could experience erosion. Inland locations will see more sunshine and generally dry weather. Friday will turn cooler, but temperatures should moderate over the weekend before another cold front potentially brings cooler air early next week.

- A prolonged stretch of dry weather is expected from Friday into early next week, except for a brief chance of showers over the eastern coastal waters Friday morning. Friday will be cooler, followed by moderating temperatures into early next week.

Discussion

Key Message 1: Hazardous Marine Conditions and Gusty Northeast Winds Through Thursday


A Nor’easter located well offshore, south of 40 degrees north latitude and 70 degrees west longitude, will remain nearly stationary through much of Wednesday before gradually moving northeast and east-northeast later Wednesday into Thursday. The storm will then move into the waters south of the Canadian Maritimes.

Meanwhile, a broad area of high pressure will continue to influence much of New England, bringing sunny skies to many inland locations. The pressure difference between the offshore storm and the high pressure will maintain gusty northeast winds, with the strongest gusts of 35 to 40 mph expected near Cape Cod and Nantucket.

The forecast and expected impacts remain largely unchanged. The greatest impacts will be over the southern and southeastern coastal waters, where rough seas will build and gale-force winds will continue. Some east-facing beaches could also experience erosion.

Over land, gusty northeast winds will be the primary concern, especially across southeastern New England. Wind gusts will generally reach 20 to 25 mph across interior areas and 25 to 35 mph along much of the coastal plain, away from Cape Cod. Nantucket could experience gusts up to 40 mph.

More clouds are expected along the southeastern New England coast Wednesday and Thursday, along with a chance of light rain showers. However, several dry periods are expected between any showers. Wednesday currently offers the best chance for rain as the offshore storm begins moving away. Cooler air will also move into the region as high pressure builds southward on Thursday.

Away from the coast, expect plenty of sunshine, with afternoon highs in the upper 50s to lower 60s and overnight lows in the middle 30s to lower 40s. Near the eastern and southeastern coast, onshore winds and additional cloud cover will keep temperatures within a narrower range, with highs in the middle to upper 50s and lows in the middle 40s to lower 50s. The persistent northeast breeze will make it feel cooler, especially along the coast.

Key Message 2: Dry Weather Friday Into Early Next Week, With Temperatures Gradually Warming After Friday

As the Nor’easter moves farther offshore, a large area of high pressure over eastern Canada will become the dominant weather feature. This high pressure system will shift south across the Northeast, eventually reaching the central Appalachian region by Monday.

Friday is expected to be the coolest day of this forecast period. Temperatures will then gradually warm through the weekend and into at least Monday.

There is still some uncertainty about how quickly a cold front will move through the region Monday night into Tuesday. Current projections suggest Tuesday could bring cooler conditions behind the front, but the timing remains uncertain.

Dry weather is expected to dominate from Friday into early next week. The only notable exception is a brief chance of showers over the eastern coastal waters Friday morning, as a weak area of low pressure, known as a surface trough, associated with the departing Nor’easter passes through the region. Even over those waters, much of the period should remain dry.
