Recreational Forecast

Mountain Forecast:
This morning there is a chance of a few scattered showers and isolated thunderstorms. In these storms winds could become strong especially over the highest peaks. Then as the day goes on it will dry out more and more with only the slight chance of an upslope shower or thunderstorm. Clouds will stick around keeping summits socked in for most of the day. As a high pressure begins to make its way over the eastern seaboard, more and more sunshine is expected making for some occasional clearing. Temperatures will increase with the approach of the high, and areas that see more sunshine will have even higher temperatures this afternoon. Humidity will also soar making for a few uncomfortable days. On Monday temperatures increase even more. Even peaks above 6000 feet could see temperatures in the 70s. Then on Tuesday a chance for showers, and even thunderstorms arrives in the afternoon, but there is little reprieve expected. If you are planning any outdoor activities, especially strenuous activities, have a plan for water, and cooling down.

Wind At Lower Elevations:
Generally weak winds today, then on Monday winds pick up slightly increasing, becoming west at 5 to 10 mph. On Tuesday winds will be similar just shifting slightly to become west-northwest.

Detailed Discussion

Scattered showers will gradually diminish this afternoon, with dry weather settling in for the next few days. Clouds remain stubborn across much of the region today, but in areas where sunshine breaks through, temperatures will rise quickly. Combined with high humidity, it may feel quite uncomfortable—so it’s important to stay hydrated and take breaks if you’re planning on heading outside. This hot and humid weather trend is only expected to ramp up.

A high-pressure system will continue to develop along the Eastern Seaboard overnight, drawing a steady stream of warm, moisture-rich air into New England. As skies clear and sunshine takes hold on Monday, temperatures will rise quickly across the region. Combined with high humidity, it will feel oppressive—heat index values could reach or exceed 100°F in some areas. These conditions can be dangerous, especially for vulnerable populations, so it’s important to take precautions: stay hydrated, limit strenuous activity, and find air-conditioned spaces when possible.

The high pressure will remain in place through Tuesday, continuing the stretch of hot and humid weather. Overnight lows will offer little relief, remaining well above normal with muggy conditions lingering through the early morning hours. The lack of overnight cooling can increase health risks, especially in urban and poorly ventilated areas.

A cold front will move through midweek, bringing a brief break from the heat with some scattered showers and slightly cooler air. However, the high-pressure system will stay nearby, keeping temperatures and humidity elevated—though not as intense as earlier in the week. By Friday and into the weekend, a more noticeable pattern shift will bring cooler, more seasonable air and lower humidity, finally offering a much-needed break from the heat.

Farm & Garden

Rainfall Forecast:
A few showers are expected to continue overnight into this morning. Then by midday most of the region will dry out. There is a chance of an isolated shower or thunderstorm mainly over central Vermont in the afternoon, but most of the day will remain dry. Then dry weather will take hold. A high pressure system will develop over the area suppressing any rain through Tuesday. Then on Wednesday a new weather system arrives, switching up the overall weather pattern.

Drying Conditions:
Fair to poor drying continues Sunday morning, then in the afternoon locally fair to good drying is expected. Fair drying will occur in locations that see a few stray showers, mainly in central Vermont. Then on Monday good to excellent drying is expected as temperatures soar. Humidities will remain elevated though rising into the 50s and 60s. Then on Tuesday good to excellent drying is expected once again. Locally fair to poor conditions are expected Tuesday afternoon with the chance of scattered showers and even a thunderstorm.

Frost:
No frost expected.
