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 Week of June 1:
There will be a morning update on Wednesday June 3, but no evening update.
There will be NO morning update on Thursday  June 4, however, there will be an evening update. Might be later than usual.
On Thursday, June 4, there will be NO Weekend Outlook e-mail, however, regular site updates resume Friday morning June 5. 
The Sunday evening  June 7 update may be a bit later than usual, but there will be an update.

Welcome to the month of June! You can find the June Almanac here.
The Atlantic Hurricane Season begins today.
Skies were overcast and it was cool here in Peterborough, NH. I think the rain is over for today and skies will gradullay clear. However, with such cold air aloft, I can’t rule out an afternoon pop up showers as the warm June sun destabilizes the atmosphere. Temps remian cool and below average today but we begin, finally, to start warming up tomorrow.

Cool and unsettled weather continues across northern New England today as a low pressure system pulls away through the Gulf of Maine. Scattered showers will continue through the morning, with a few isolated showers or even a rumble of thunder possible again this afternoon. Conditions gradually improve through the week as a warmer and more stable weather pattern develops. Temperatures will climb into the 70s for much of the region by midweek, with some areas potentially reaching the 80s late in the week. While there are chances for showers on Tuesday and again next weekend, neither period currently appears likely to bring an all-day washout.

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

Summary - Northern New England - New Hampshire and Maine

Summary:
Cool and unsettled weather continues across northern New England today as a low pressure system pulls away through the Gulf of Maine. Scattered showers will continue through the morning, with a few isolated showers or even a rumble of thunder possible again this afternoon. Conditions gradually improve through the week as a warmer and more stable weather pattern develops. Temperatures will climb into the 70s for much of the region by midweek, with some areas potentially reaching the 80s late in the week. While there are chances for showers on Tuesday and again next weekend, neither period currently appears likely to bring an all-day washout.

Key Messages:
 - Low pressure will continue moving southeast across the region, leading to scattered showers and possibly a few rumbles of thunder through the morning. A few additional isolated showers are possible later this afternoon.
 - A warming trend with slightly above average temperatures is expected by the end of the week.
 - Chances for precipitation return Tuesday and next weekend, but no day is expected to be a washout.

What has changed since the last Forecast Update?
No significant changes were needed with this morning update. The near term forecast was refreshed as showers continue moving through the area with low pressure now centered offshore.

What this means for you:
Expect a damp start to the day with scattered showers and perhaps a brief thunderstorm, especially during the morning hours. Outdoor plans may need some flexibility, but many areas will also see dry periods. After today, the weather trend turns more favorable with warmer temperatures, lower humidity for much of the week, and several opportunities for outdoor activities. A few isolated showers remain possible Tuesday, and another chance for precipitation returns next weekend, but widespread heavy rain is not expected at this time.

Issued 614 AM EDT Monday, June 1, 2026

**What Has Changed**


No significant changes were needed with this morning update. The near term forecast was refreshed as showers continue moving through the area with low pressure now centered offshore. The aviation discussion was also updated to reflect the latest 8:00 AM EDT TAF forecast package.

**Key Messages**

1. Low pressure will continue moving southeast across the region, leading to scattered showers and possibly a few rumbles of thunder through the morning. A few additional isolated showers are possible later this afternoon.

2. A warming trend with slightly above average temperatures is expected by the end of the week.

3. Chances for precipitation return Tuesday and next weekend, but no day is expected to be a washout.

**Discussion**

**Key Message 1 Description**


A surface low pressure system will continue moving southeast into the Gulf of Maine this morning, with an upper level low pressure system following closely behind. This setup will produce another round of showers moving from north to south across the forecast area between approximately 3:00 AM EDT and 11:00 AM EDT. The lowest chances for showers will be across the Kennebec River Valley and Midcoast areas, which will be farther east of the strongest large scale lifting mechanism, known as synoptic forcing.

Thunderstorms are not expected to be widespread, but a few rumbles of thunder remain possible due to limited atmospheric instability.

Most of the precipitation will exit during the morning hours, but daytime heating could help generate a few additional showers this afternoon. Atmospheric instability will again be modest, so an isolated thunderstorm or two cannot be ruled out, although coverage should remain limited.

Morning low temperatures ranged from the upper 30s across northern areas to the lower and middle 40s farther south. Afternoon highs today will remain cool, reaching the upper 50s to middle 60s. Overnight lows tonight will be similar, ranging from the middle and upper 30s north to the middle 40s south.

**Key Message 2 Description**

The upper level trough, an elongated area of cooler and less stable air aloft, will finally loosen its grip on New England by Tuesday. This occurs as the omega block pattern, a large scale weather pattern that slows weather systems across North America, begins to break down. At the same time, an unusually strong ridge of high pressure over Canada shifts southeast into the Northeastern United States.

For local weather conditions, this should result in several days of generally quiet weather and near seasonable temperatures as a 1025 millibar high pressure system settles over the region. Winds will remain light, allowing sea breezes to develop along the coast on many afternoons beginning Tuesday.

Much of the week should feature afternoon temperatures in the 70s. Some locations could reach the lower 80s by Thursday and Friday as warmer air develops aloft. Humidity levels should remain comfortable for most of the week, with dew points generally in the 50s. Humidity could become somewhat more noticeable next weekend depending on the timing of an approaching upper level disturbance, known as a shortwave.

**Key Message 3 Description**

There are chances for precipitation on Tuesday and again next weekend, but neither period currently appears likely to produce widespread or long lasting rainfall.

On Tuesday, leftover cold air aloft from the recent upper level system will still be nearby. High resolution forecast guidance suggests the atmosphere will cool rapidly with height, a sign of instability that can support developing showers and thunderstorms. Freezing levels are expected to remain relatively low, near 6,000 feet above sea level.

Combined with modest instability, measured by CAPE (Convective Available Potential Energy), this may be sufficient to generate a few heavier downpours and isolated thunderstorms during the day.

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

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

Summary:
Cooler than normal weather continues across southern New England today as a fresh push of cool air arrives from the northeast. A few isolated afternoon showers are possible, but most locations will remain dry. Temperatures begin a gradual warming trend Tuesday and continue warming through midweek. Forecast confidence decreases late in the week as meteorologists monitor the possibility of an offshore low pressure system. Current indications favor mainly dry and warmer conditions, but a closer track could bring showers, especially to eastern Massachusetts, Cape Cod, and the Islands. Another opportunity for showers may arrive next weekend.

Key Messages:
- Expect a few isolated showers around today with cooler temperatures. Warmer Tuesday with isolated showers or a stray storm possible.
 - Forecast confidence decreases for late week. Conditions more likely lean dry and warm, but we continue to monitor the potential for an offshore system to bring showers.

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

What this means for you
Expect a cool start to the week with temperatures running below average today. Most areas will see plenty of dry weather despite a few isolated afternoon showers. Warmer and more comfortable conditions return Tuesday and Wednesday, with many locations reaching the 70s. By late week, temperatures could climb well into the 80s, especially in the Connecticut Valley, if an offshore storm remains far enough away. While the forecast becomes less certain later in the week, no widespread washout is expected at this time.

National Weather Service Boston/Norton MA
Issued 324 AM EDT Monday, June 1, 2026

**What Has Changed**


No significant changes to the forecast.

**Key Messages**

* Expect a few isolated showers around today with cooler temperatures. Warmer Tuesday with isolated showers or a stray storm possible.

* Forecast confidence decreases for late week. Conditions more likely lean dry and warm, but we continue to monitor the potential for an offshore system to bring showers.

**Discussion**

**Key Message 1, Expect A Few Isolated Showers Around Today With Cooler Temperatures. Warmer Tuesday With Isolated Showers Or A Stray Storm Possible.**


Another push of cool air arrives today on northeasterly winds. This will bring a cool day across southern New England, with temperatures running below normal for early June. Afternoon highs will generally reach the upper 50s to middle 60s. The Connecticut Valley will be somewhat warmer, reaching the middle to upper 60s, while onshore winds keep eastern coastal areas cooler, with many locations remaining in the lower 60s.

A weak and fast moving disturbance, known as a shortwave, will pass through the region today. A shortwave is a small scale ripple in the atmosphere that can help trigger cloud development and showers. Available moisture will be limited, so only isolated afternoon pop up showers are expected.

On Tuesday, the core of the colder air aloft begins shifting east, although southern New England remains under a broad upper level trough. An upper level trough is an area of lower pressure and cooler air in the middle and upper atmosphere. As atmospheric heights slowly rise, temperatures should respond by warming several degrees compared to Monday.

High temperatures Tuesday are expected to reach the lower to middle 70s across much of the region. Local sea breezes may keep some coastal communities in the upper 60s. Another weak shortwave may move through during the afternoon, bringing another chance for isolated showers. There is also some indication of marginal instability developing. Instability refers to the atmosphere becoming more favorable for rising air and thunderstorm development. As a result, an isolated thunderstorm cannot be ruled out.

Wednesday looks mainly dry as an amplified ridge of high pressure builds eastward. This ridge will gradually push the upper trough farther offshore while allowing temperatures to continue warming. Temperatures about 5,000 feet above the ground, referred to as 850 millibar temperatures, increase slightly, supporting afternoon highs in the 70s across most locations. The warmest valleys could reach between 75 and 80 degrees.

**Key Message 2, Forecast Confidence Decreases For Late Week. Conditions More Likely Lean Dry And Warm, But We Continue To Monitor The Potential For An Offshore System To Bring Showers.**

Forecast uncertainty increases heading into late week as meteorologists evaluate the evolution of the upper level weather pattern.

Forecast models generally agree that a strong upper level ridge will continue building into the Northeast, gradually pushing the trough farther offshore. However, model differences increase regarding the possible development of a closed low pressure system near the Carolinas that could move northward.

Most ensemble guidance, which uses many model simulations to assess possible outcomes, currently favors a track well offshore. If that scenario occurs, southern New England would remain mostly dry while experiencing a noticeably warmer air mass. Under this outcome, temperatures could reach the lower to middle 80s across much of the region, with parts of the Connecticut Valley potentially approaching 90 degrees.

Some individual forecast solutions continue to suggest a closer track near the traditional 40 North, 70 West benchmark location used by forecasters to monitor coastal storm tracks. If that occurs, showers could reach portions of eastern Massachusetts, including Cape Cod and the Islands, Thursday into Friday.

While details remain uncertain, there is increasing agreement among ensemble guidance that another weather system may bring a period of showers sometime on Saturday.
