**Discussion**

**Key Message 1, Scattered showers and isolated thunderstorms return Sunday afternoon into early evening, focused mainly across eastern New England. Cooler and drier conditions arrive Sunday night.**

Sinking air behind a departing cold front, known as subsidence, is allowing mainly clear skies this morning. However, this quiet weather will be short-lived as an upper-level trough and an embedded disturbance, known as a shortwave, move south out of northern New England this afternoon.

Atmospheric lift associated with these features appears favorable for shower development, but instability remains somewhat limited. Forecast values are generally below 500 joules per kilogram, which is a measure of the atmosphere's ability to support thunderstorm growth. As a result, the expectation remains for scattered showers rather than a widespread soaking rain.

That said, some showers could produce locally heavy downpours. Atmospheric moisture levels, measured by precipitable water values, are around 1.5 inches, which is sufficient to support brief periods of heavier rainfall. Severe thunderstorms are not expected, but a few rumbles of thunder remain possible. Colder air higher in the atmosphere could also allow for isolated small hail.

While showers may develop anywhere across southern New England, the greatest coverage is expected across central and eastern Massachusetts and Rhode Island, where instability is forecast to be slightly stronger.

Cooler air will arrive gradually, allowing afternoon temperatures to still climb into the upper 70s to lower 80s before northeast winds develop later in the day. Drier and noticeably cooler air then moves into the region overnight. By Monday morning, low temperatures should fall into the middle to upper 40s across outlying areas and the lower to middle 50s in urban locations.

**Key Message 2, Dry with seasonable temperatures Monday.**

The upper-level trough responsible for Sundays showers will move east of New England by early Monday. At the same time, a strengthening ridge of high pressure aloft will expand toward the eastern United States.

As the trough evolves into a cutoff low over the Canadian Maritimes, it will help slow the eastward movement of the ridge. This setup favors a return to warmer summerlike conditions later in the week.

Monday is expected to be the coolest day of the upcoming week as cooler air continues to drain southward into the region. Forecast soundings indicate a well-mixed atmosphere during the afternoon, meaning cooler air from above can mix down to the surface efficiently.

Temperatures will vary by location. Cape Cod, the Islands, Boston, and much of the eastern coastline should remain mainly in the 70s. Farther inland, especially in the Connecticut River Valley, highs should reach the lower 80s.

**Key Message 3, Summerlike heat and humidity returns next week, no notable storms, though a front may bring a period of showers and thunderstorms mid to late week.**

For much of next week, a stronger-than-normal upper-level ridge extending northward toward Hudson Bay will promote mainly dry weather along with increasing heat.

Temperatures several thousand feet above the ground continue to warm through the week, a signal that supports increasingly hot surface temperatures. Highs should reach the middle 80s to near 90 degrees Tuesday, followed by upper 80s to lower 90s across many locations from Wednesday through Friday.

The first half of the week should feature relatively comfortable humidity levels, with dewpoints mainly in the 50s. By late week, dewpoints are expected to rise into the 60s, making conditions feel noticeably more humid.

Looking beyond the current forecast period, there is an emerging signal that the heat could persist into next weekend. The Climate Prediction Center is highlighting a Slight Risk, or a 20 to 40 percent probability, of extreme heat across portions of the Northeast. While confidence is still developing, the trend bears watching and heat advisories may eventually become necessary.

As for precipitation, no significant rainfall is expected through much of next week. However, a cold front later in the week could bring a period of showers and thunderstorms as heat and humidity continue to build across the region.
