Area Forecast Discussion National Weather Service Boston/Norton MA 401 AM EDT Sun Jun 2 2024

SYNOPSIS
High pressure continues to move over New England, keeping the region dry. Low chance for showers Sunday night with a weak shortwave passing over the region. High pressure brings warm and dry weather through the middle of next week, then the weather pattern becomes unsettled toward the end of the week as a frontal system approaches from the west.

NEAR TERM /UNTIL 6 PM THIS EVENING/
Surface high pressure centered near Bermuda continues the stretch of wonderful weather across the region. Another warm and mainly sunny day, very similar to Saturday, but do look for clouds to return from west to east later this afternoon ahead of an approaching weak shortwave. Given the similar setup, today's high temperatures should be similar to Saturday, highs return to the lower and middle 80s. Do expect a seabreeze to develop once again mid morning, leading to onshore flow along the coast, the immediate coast likely few degrees cooler in the middle and upper 70s. But all around a great day.

SHORT TERM /6 PM THIS EVENING THROUGH 6 PM MONDAY/
Tonight: As mentioned above, a weak shortwave cuts across the area with the focus on any spot showers in far southwest CT and western MA. Think there is enough dry air near the surface that these will be very light or virga, capped the POPs at 24 percent, leading to a "Slight Chance". The increased cloud cover and the light westerly wind keep temperatures in the low 60s, a few spots in northern MA settle into the upper 50s.

Monday: High pressure still in control, a secondary high over the Gulf of Maine shifts north into Quebec and 500mb heights increasing as ridging redevelops over the northeast. There could be weak shortwave energy moving down from the north, likely only adding some clouds, but would not be shocked if there were an isolated brief shower, with PWATS around 0.8". Did introduce a few area of "Slight Chance" showers, 15-20 percent, across the CWA Tough to say exactly where these will pop-up, but at the end of the day, not anticipating any adverse weather. Still fairly warm, highs return to the low and middle 80s despite an easterly wind. That said, the immediate coast of eastern MA will have highs in the middle 70s, perhaps the lower 70s for the outer Cape.

LONG TERM /MONDAY NIGHT THROUGH SATURDAY/
Highlights:

* Tranquil and dry weather through Wed with mild temps inland, cooler near the coast.

* Increasing threat of showers/thunderstorms late this week and early next weekend. Timing remains uncertain.

Details:

Have the greatest confidence in the overall forecast details through Wednesday. After then, significant timing differences arise within the latest guidance suite, mainly from the impact of a strengthening mid level shortwave leading to development of a mid level cutoff over the Great Lakes late next week. This is the main source of uncertainty with this portion of the forecast.

Dry weather persists into Wednesday.

Latest deterministic guidance has sped up the onset timing for showers to some time Wednesday night. The consensus timing however, favors a slower onset time. As such, favored the NationalBlend solution since it is ensemble-based, but still only tried to trend the timing with the previous forecast. Thee is that much uncertainty with the timing. All that said, have the greatest confidence in at least some rainfall some time from Thursday evening into early Friday morning as a frontal system approaches from the west.

There is just as much uncertainty in how fast, or far, this front gets east of southern New England into this weekend. Thus, the risk for showers may continue into next weekend.

Near to above normal temperatures expected through this portion of the forecast.
