A cool start to the day, but we should warm up to seasonal highs later this morning. Dry, sunny, and increasingly warmer air to start the week, with hot/humid air to end it. Thunderstorms are likely, and in fac t, we could use the rain.
Last night I was listening to the Bard Owls we have here at 3:30 AM. Their haunting "who cooks for you" call starts with one, then many others join in. It is so nice to have the windows open this time of year, is it not?
Good Morning. What the National Weather Service is calling "the first true heat wave of the summer" will build across much of the country this week, driven by an impressive ridge of high pressure that's pulling the jet stream well to the north and leaving hot, humid conditions in its wake. Starting in the Central U.S. Tuesday and Wednesday before moving east, the heat could threaten dozens of record highs from the Plains to the Northeast. Temperatures could run 15 to 20 degrees above average by week's end, with "feels like" temperatures (aka heat indices) topping the triple digits in some spots.
A stretch of pleasant early summer weather continues through Tuesday as high pressure keeps skies mainly fair, humidity comfortable, and temperatures warming into the upper 70s and 80s. Conditions turn noticeably more humid beginning Wednesday, with temperatures reaching the 80s to lower 90s through the end of the week. Daily chances for showers and thunderstorms return, especially from Wednesday night onward. While the risk for severe weather remains low for now, forecasters are monitoring a cold front that could bring stronger thunderstorms late Friday into Saturday.

Summary:
A stretch of pleasant early summer weather continues through Tuesday as high pressure keeps skies mainly fair, humidity comfortable, and temperatures warming into the upper 70s and 80s. Conditions turn noticeably more humid beginning Wednesday, with temperatures reaching the 80s to lower 90s through the end of the week. Daily chances for showers and thunderstorms return, especially from Wednesday night onward. While the risk for severe weather remains low for now, forecasters are monitoring a cold front that could bring stronger thunderstorms late Friday into Saturday.
Key Messages:
- High pressure brings fair weather today and Tuesday with warming temperatures and comfortable humidity levels.
- Humidity increases on Wednesday and will remain elevated through the end of the week with daily chances for showers and thunderstorms. Highs in the 80s to low 90s combined with the humidity will pose a heat risk.
What has changed since the last Forecast Update?
No changes were needed with this forecast update.
What this means for you:
Enjoy the most comfortable weather of the week today and Tuesday, with warm afternoons and relatively low humidity. Beginning Wednesday, the air will feel much more muggy as tropical moisture increases across the region.

**What Has Changed**
No changes were needed with this forecast update.
**Key Messages**
1. High pressure brings fair weather today and Tuesday with warming temperatures and comfortable humidity levels.
2. Humidity increases on Wednesday and will remain elevated through the end of the week with daily chances for showers and thunderstorms. Highs in the 80s to low 90s combined with the humidity will pose a heat risk.
**Synopsis**
High pressure building in from the northwest this morning will settle south of New England by Tuesday. This will bring fair weather with afternoon highs today in the upper 70s to lower 80s, increasing into the middle 80s on Tuesday. Northwest winds higher in the atmosphere will help keep dew points, a measure of moisture in the air, in the 40s today and the 50s on Tuesday, making conditions feel comfortable.
By Wednesday, a strong ridge of high pressure aloft will build over the Northeast. At the same time, a persistent trough, an area of lower pressure and unsettled weather, over the Northern Plains will help keep the ridge centered near the East Coast through Friday. Smaller disturbances moving along the northern edge of the ridge may trigger periods of showers and thunderstorms.
Forecast guidance remains in good agreement that temperatures higher in the atmosphere will be well above normal, while moisture levels across the Northeast will also be unusually high. The latest National Blend of Models guidance indicates dew points climbing into the middle 60s by Wednesday, with humid conditions likely continuing through Friday and possibly into Saturday.
The warmer air aloft will support afternoon highs in the 80s to lower 90s. However, clouds and daily chances for showers and thunderstorms may prevent temperatures from reaching their maximum potential on some days.
Forecast models generally agree that the first notable disturbance will move into the region late Wednesday into Wednesday night, bringing the best chance for showers and thunderstorms through the end of the work week. The atmospheric ingredients typically associated with severe thunderstorms do not currently appear particularly impressive, so the risk for strong storms remains low at this time.
The ridge is expected to rebuild over the Northeast on Thursday, although daytime heating could still trigger scattered afternoon showers and thunderstorms. By Friday, the trough over the Northern Plains will attempt to move eastward, increasing winds higher in the atmosphere across the eastern Great Lakes while pushing a cold front toward New England.
Most forecast guidance delays the arrival of this front until late Friday, and some solutions do not bring it through New England until Saturday, if it moves through at all. As a result, Friday is expected to remain very warm and humid.
This approaching front bears watching because it could provide the focus needed for stronger to severe thunderstorms. Machine Learning guidance from Colorado State University (CSU), which uses artificial intelligence techniques to identify severe weather signals, has begun highlighting that possibility. Additional forecast updates later this week will help determine whether that threat becomes more significant.

Scattered afternoon and evening showers and thunderstorms are possible Wednesday through Friday as disturbances move through a warm and increasingly humid atmosphere. Some areas may experience heat-related impacts, especially in urban locations.
Key Messages:
- Pleasant, dry, and seasonable weather today with low humidity and abundant sunshine.
- Increasing heat and humidity this week with afternoon thunderstorm chances Wednesday through Friday.
What has changed since the last Forecast Update?
No significant forecast changes.
What this means for you
Today is the pick of the week for outdoor activities, featuring sunshine, comfortable humidity levels, and temperatures mainly in the 70s. Starting Tuesday, summerlike heat returns and humidity will steadily increase. If you work or spend time outdoors later this week, be prepared for hot conditions and the possibility of afternoon thunderstorms. Nights will also become warmer, making it harder for some people to cool down. Heat impacts may become more noticeable by late week, especially in cities and densely populated areas.

**What Has Changed**
No significant forecast changes.
**Key Messages**
* Pleasant, dry, and seasonable weather today with low humidity and abundant sunshine.
* Increasing heat and humidity this week with afternoon thunderstorm chances Wednesday through Friday.
**Discussion**
**Key Message 1, Pleasant, dry, and seasonable weather today with low humidity and abundant sunshine**
A very nice day is expected across southern New England with near-seasonable temperatures, low humidity, and plenty of sunshine.
A mid-level trough, an area of cooler air and lower pressure several miles above the ground, is moving into the Canadian Maritimes while high pressure builds in from the west. This setup will bring north to north-northeast winds today. During the morning and early afternoon, the difference in pressure between these weather systems will create breezy conditions, with winds around 10 to 15 mph and occasional higher gusts along the immediate coastline.
As the day progresses and the pressure difference weakens, winds will gradually shift to the southeast and then become south-southwest after sunset.
Afternoon high temperatures will generally range from the 70s to near 80 degrees, with the warmest readings inland and away from the ocean. Coastal areas will mainly remain in the lower 70s, while parts of the Outer Cape and Islands could stay in the upper 60s.
Tonight, high pressure settles directly over the region and winds become light. This setup favors radiational cooling, which means heat absorbed during the day can escape efficiently into the atmosphere overnight. Temperatures will drop into the 40s in many locations, while urban areas hold onto more warmth with lows in the middle 50s.
Because of the rainfall from this past weekend, some areas may see patchy fog develop overnight where winds become calm.
**Key Message 2, Increasing heat and humidity this week with afternoon thunderstorm chances Wednesday through Friday**
Summerlike heat and humidity will return this week as a strong mid-level ridge, a large area of warmer air and higher pressure aloft, expands into the Northeast along with surface high pressure.
Tuesday begins the warming trend. Temperatures several thousand feet above the ground are forecast to increase significantly, supporting afternoon highs in the upper 80s to lower 90s through much of the week.
National Weather Service HeatRisk guidance indicates the potential for heat-related impacts, with widespread moderate impacts and isolated areas of major impacts possible, especially in urban centers later in the week.
One factor that could limit temperatures somewhat will be increased cloud cover and thunderstorm activity from midweek onward. If clouds and storms become more widespread, temperatures may stay just low enough to avoid the need for formal heat advisories. Even so, anyone working outdoors should prepare for another stretch of unusually warm weather.
Nighttime temperatures will also remain elevated, generally staying in the 60s, which will provide limited overnight cooling.
Cloud cover and thunderstorm chances increase from Wednesday through Friday. By Wednesday, southern New England is expected to be located near the edge of the upper-level ridge, with a more west-to-east weather flow pattern developing overhead. This setup allows small disturbances in the atmosphere to move across the country and into New England.
As these disturbances move through a warm, humid, and increasingly unstable air mass, scattered showers and thunderstorms may develop. While the exact timing of individual storms cannot yet be determined, there is moderate confidence that afternoon and evening showers and thunderstorms will be possible each day from Wednesday through Friday.
The summerlike heat may continue into next weekend. The Hazardous Weather Outlook currently highlights portions of central and western southern New England for potentially hazardous heat conditions.
