Meteorologist Matt Noyes here with your Tuesday Insights forecast, and there’s a lot happening both with the weather and here at 1DegreeOutside. First, an exciting announcement: our brand-new 24/7 weather stream launches Wednesday! You’ll be able to watch it on YouTube, on our website, and right at the top of the 1DegreeOutside app once you update to the latest version. It’s a first for New England and we can’t wait to bring you continuous weather coverage.
Now, on to the weather. A carved-out trough in the jet stream is taking hold across the Eastern United States, and it doesn’t want to let go. That means heat and humidity stay suppressed to our south while repeated disturbances ride through the Northeast, delivering multiple rounds of showers and thunderstorms. This is the setup not just for this week, but for the holiday weekend as well.
Wednesday brings the first round, with scattered showers and downpours developing by late morning and afternoon. Some cells may produce lightning, small hail, or brief gusty winds — not widespread severe weather, but isolated stronger storms are possible. Skies clear overnight with crisp lows in the 40s.
Thursday features a brief warmup, with highs in the mid to upper 70s. Most areas stay dry, but late in the day showers arrive in northern New England, leading into a more active Friday.
Friday is the main event, as a cold front sweeps through New England with showers, downpours, and embedded thunder becoming more widespread from midday into the afternoon. Once that front clears, drier and more comfortable air arrives for the weekend.
Saturday will be cooler, with highs in the 60s to low 70s, and while most of New England enjoys pleasant air, northern areas in particular will still see scattered showers thanks to lingering upper-level energy. The farther south you go, the fewer the showers. Sunday and Labor Day Monday look better, with sunshine returning and more limited shower chances.
In the tropics, things are quiet. Tropical Storm Fernand is falling apart in the North Atlantic, and dry air dominates the basin, leaving no active disturbances for now. The Eastern Pacific may turn more favorable by the end of the first week of September, but the Atlantic remains quiet for the time being.
Overall, it’s a stretch of weather defined by a persistent trough: cooler, more comfortable air for New England, punctuated by scattered showers. No big heat, no widespread washouts, but a few interruptions in the form of pop-up showers — especially as we head into the holiday weekend.
