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:
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 began June 1. Updates will be available daily from now until Nov. 30.
Another dry and warm day ahead! Mostly cloudy and mild tonight. A slow moving cold front arrives on Saturday. As this front slowly presses south, expect showers and thunderstorms to pop up, mainly in the afternoon and evening. Some may be strong. Still unsettled on Sunday with a chance of showers. Sunny, dry weather returns on monday. It will be cooler, but we start to warm right back up by Tuesday.
Warmer and more humid weather returns Saturday with the potential for scattered thunderstorms, some of which could become strong to severe, especially across New Hampshire and far western Maine. Gusty winds and small hail are the primary threats. A slow moving cold front brings additional rounds of showers on Sunday along with somewhat cooler temperatures. Early next week will be comfortable, but temperatures are now expected to warm more aggressively by the middle and latter part of the week, with many locations reaching the 80s and some southern areas approaching 90 degrees.

Weather Summaries and Full Area Forecast Discussions - North (Edited)
Summary - Northern New England - New Hampshire and Maine
Summary:
Warmer and more humid weather returns Saturday with the potential for scattered thunderstorms, some of which could become strong to severe, especially across New Hampshire and far western Maine. Gusty winds and small hail are the primary threats. A slow moving cold front brings additional rounds of showers on Sunday along with somewhat cooler temperatures. Early next week will be comfortable, but temperatures are now expected to warm more aggressively by the middle and latter part of the week, with many locations reaching the 80s and some southern areas approaching 90 degrees.
Key Messages:
- The chance for showers and thunderstorms returns Saturday with warmer temperatures retreating south of the forecast area. A Marginal Risk of severe thunderstorms exists for New Hampshire and far western Maine, with a Slight Risk across southern New Hampshire. Strong to severe storms may contain gusty winds and small hail.
- A slow moving front crosses New England on Sunday, bringing showers and a relatively cooler air mass.
- After a brief and relatively cool period early next week, temperatures rebound again by midweek.
What has changed since the last Forecast Update?
Temperatures have trended warmer for early next week, before a more pronounced warmup develops through the remainder of the week.
What this means for you:
Saturday is the day to watch for stronger thunderstorms, particularly if you live in New Hampshire or western Maine. While not everyone will see severe weather, any stronger storm could produce damaging wind gusts and small hail. Sunday looks wetter overall with periods of showers as a cold front slowly moves through. The cooler air behind the front will be brief, and a significant warmup is expected by the middle of next week with summerlike temperatures becoming increasingly likely.

**What Has Changed**
Temperatures have trended warmer for early next week, before a more pronounced warmup develops through the remainder of the week.
**Key Messages**
1. The chance for showers and thunderstorms returns Saturday with warmer temperatures retreating south of the forecast area. A Marginal Risk of severe thunderstorms exists for New Hampshire and far western Maine, with a Slight Risk across southern New Hampshire. Strong to severe storms may contain gusty winds and small hail.
2. A slow moving front crosses New England on Sunday, bringing showers and a relatively cooler air mass.
3. After a brief and relatively cool period early next week, temperatures rebound again by midweek.
**Synopsis**
**Key Message 1 Description**
Other than isolated to scattered showers late this afternoon into early evening across parts of central Maine, conditions remain dry through tonight. Winds become light and temperatures fall into the lower to middle 50s.
A stationary front located north of the region will help funnel moisture into northern New England on Saturday. A weak disturbance in the upper atmosphere, referred to by forecasters as a shortwave, will move across the area and likely produce widespread cloud cover along with a chance for light showers during the morning before shifting east.
How quickly the clouds break up during the afternoon will play a major role in determining thunderstorm development and intensity. Forecast guidance shows a wide range of possible instability values, known as CAPE (Convective Available Potential Energy), which measures the amount of fuel available for thunderstorms. Current projections suggest the best chance for stronger storms will be west of a line roughly from Portland to Rangeley. Thunderstorms remain possible across the entire region, but storms should gradually weaken farther east.
Thunderstorms are expected to develop along a pre-frontal trough, which is a zone of changing winds and pressure ahead of the main cold front. The atmosphere appears supportive of thunderstorm development, and isolated strong to severe storms are possible. Forecasts indicate enough wind shear, which is a change in wind speed and direction with height, to help storms organize and strengthen. Additional moisture arriving from the Great Lakes region will also support storm development.
The amount of instability remains the largest uncertainty, but the greatest potential appears focused on New Hampshire and far western Maine. Damaging wind gusts are expected to be the primary threat, although small hail is also possible, especially if storms remain more isolated. As storms begin to merge into lines during the afternoon, the wind threat could increase.
Storm coverage should decrease during the evening with the severe weather threat diminishing. A few showers may continue overnight, especially north of the mountains.
**Key Message 2 Description**
High pressure settles southward on Tuesday and Wednesday while a strong upper-level ridge of high pressure expands across the northeastern United States and eastern Canada. This pattern supports a notable warming trend through midweek.
High temperatures are expected to reach the middle 80s by Tuesday, then climb into the middle 80s to lower 90s on Wednesday. The strongest part of the ridge is forecast to remain northwest of New England across Quebec and Ontario, which may actually allow some of the warmest temperature departures from normal to occur across northern areas.
Forecasters are also monitoring the potential for a backdoor cold front late next week. A backdoor cold front approaches from the northeast rather than from the west, which is more typical. At this time, the orientation of the ridge suggests any such front may be pushed south and east before significantly affecting the region.
If this pattern develops as expected, a prolonged stretch of summerlike warmth could continue through at least the latter part of next week.
**Key Message 3 Description**
A cold front will move only slowly across northern New England on Sunday while an area of low pressure tracks through southern Quebec. This setup will bring additional rounds of showers to the region.
Compared to previous forecasts, the front now appears weaker and is expected to produce less overall precipitation. Showers remain likely, but the upper-level low pressure system is not forecast to strengthen as much as earlier model runs suggested. As a result, rainfall is expected to be more intermittent rather than widespread and persistent. The front should clear south of the region by late Sunday evening.
The cooler air mass behind the front also appears less impressive than earlier forecasts indicated. Monday will still feel somewhat cooler as high pressure builds in, but temperatures are expected to reach the lower 70s across northern areas and near 80 degrees across southern New Hampshire.
From there, temperatures are forecast to steadily rise through the middle of next week as the warmer pattern re-establishes itself.
Weather Summaries and Full Area Forecast Discussions - South (Edited)
Summary - Southern New England - Massachusetts/Northern CT/Rhode Island
Summary:
Unseasonably warm to hot weather will continue through Saturday across southern New England with dry conditions for most locations. The greatest weather concern arrives Saturday evening, when showers and thunderstorms develop, some of which could become strong to severe with damaging wind gusts and heavy downpours. Sunday will feature periods of showers and possible thunderstorms, but rainfall is expected to be more scattered than widespread. Cooler and drier weather returns Monday and Tuesday before a warming trend develops again by the middle of next week.
Key Messages:
- Unseasonably warm to hot temperatures continue today and Saturday with dry weather persisting.
- Increasing risk for showers and a few strong to severe thunderstorms Saturday evening. Sunday trends somewhat warmer with periods of showers and possible thunderstorms.
- Dry and cooler conditions return early next week with an onshore wind flow, before temperatures trend more summerlike by midweek.
What has changed since the last Forecast Update?
Forecasters continue refining the expected temperatures, timing of precipitation, and the risk for thunderstorms, some of which could become severe, this weekend.
What this means for you
If you have outdoor plans Friday or during most of Saturday, the weather should cooperate with plenty of warmth and generally dry conditions. Keep an eye on the forecast if you have plans Saturday evening, as thunderstorms could become strong enough to produce damaging wind gusts and brief heavy rain. Beachgoers should also be aware of an increased rip current risk on some southern New England beaches Saturday. After a cooler start to next week, summerlike warmth is expected to return by midweek.

**What Has Changed**
Forecasters continue refining the expected temperatures, timing of precipitation, and the risk for thunderstorms, some of which could become severe, this weekend.
**Key Messages**
* Unseasonably warm to hot temperatures continue today and Saturday with dry weather persisting.
* Increasing risk for showers and a few strong to severe thunderstorms Saturday evening. Sunday trends somewhat warmer with periods of showers and possible thunderstorms.
* Dry and cooler conditions return early next week with an onshore wind flow, before temperatures trend more summerlike by midweek.
**Discussion**
**Key Message 1, Unseasonably Warm to Hot Temperatures Continue Today and Saturday with Dry Weather Persisting**
There are no significant changes to the forecast through Saturday daytime. Confidence remains high that dry weather will continue along with temperatures that are much warmer than normal for early June.
The primary weather feature is a large area of high pressure across the southeastern United States that will gradually move offshore this weekend. This system is helping maintain the warm and dry pattern across southern New England.
Meteorologists continue monitoring temperatures several thousand feet above the ground, known as 850 millibar temperatures. These values remain warm today and become even warmer on Saturday. Combined with efficient mixing of the atmosphere, this should allow afternoon temperatures to climb well into the upper 80s and lower 90s inland.
Cloud cover and increasing humidity on Saturday may limit some daytime heating, but temperatures are still expected to remain well above normal. Average highs for early June are typically in the lower 70s.
A west wind today should allow even coastal communities to warm efficiently. On Saturday, a stronger southwest wind will keep some southern coastal areas cooler, mainly in the upper 70s to lower 80s.
Humidity levels remain comfortable today with dew points in the 50s. By Saturday, dew points rise into the upper 50s and lower 60s, creating a somewhat more humid feel, though conditions are not expected to become excessively uncomfortable.
For beachgoers, there is a moderate risk of rip currents Saturday along east-facing beaches of Cape Cod, ocean-facing beaches of Nantucket and Marthas Vineyard, and south-facing beaches from Point Judith, Rhode Island, to Westport, Massachusetts. Always check local conditions and follow lifeguard guidance.
**Key Message 2, Increasing Risk for Showers and a Few Strong to Severe Thunderstorms Saturday Evening. Sunday Trends Somewhat Warmer with Periods of Showers and Possible Thunderstorms**
Confidence continues to increase that most, if not all, daylight hours Saturday will remain dry. A brief afternoon shower cannot be ruled out north and west of the Interstate 91 corridor.
Increasing warmth and humidity will create an atmosphere favorable for thunderstorm development by late afternoon and evening. Meteorologists measure atmospheric instability using a parameter called CAPE, Convective Available Potential Energy. Forecast values suggest enough instability to support thunderstorm development, with some locations potentially becoming more unstable than others.
Another important factor is wind shear, which measures how wind speed and direction change with height. Wind shear is expected to strengthen Saturday evening, creating an environment that could support stronger thunderstorms.
As a result, southern New England is now under a marginal risk for severe thunderstorms. The primary threats include damaging straight-line wind gusts and locally heavy downpours. Atmospheric moisture levels will increase significantly, supporting periods of heavy rainfall within stronger storms.
Forecast models designed specifically for thunderstorm prediction are beginning to better resolve this time period, but additional refinements in storm timing and location are still expected.
By Sunday morning, slightly drier conditions may briefly develop behind the front, although humidity will remain noticeable. A mix of clouds and sunshine is expected.
Another upper-level disturbance is forecast to move across southern New England Sunday afternoon. Recent forecast trends suggest the main low pressure center will track farther north into the Gulf of Maine. Because of this, rainfall is expected to be more scattered and showery rather than widespread.
The highest concentration of showers and general thunderstorms is expected across eastern portions of southern New England. Cooler air arrives gradually, allowing temperatures to still reach the upper 70s to lower 80s before northeast winds increase later in the day.
**Key Message 3, Dry and Cooler Conditions Return Early Next Week with Onshore Flow, Before Temperatures Trend More Summerlike by Midweek**
Monday is expected to be cooler and generally drier, although some uncertainty remains regarding how quickly the departing upper-level trough moves away from the region. This will affect both cloud cover and temperatures.
Current expectations call for cooler conditions Monday, followed by a gradual warming trend beginning Tuesday and continuing into the middle of next week.
High pressure is expected to build back into the region by Tuesday, supporting mainly dry weather through at least the middle of next week. Temperatures should return to the 80s by midweek, bringing another stretch of summerlike weather to southern New England.
