New England Weather Forecast: Warm, Humid Weather Returns

The start of the workweek saw cooler temperatures and showers as a coastal low moved into New England and began to lose steam. But Greater Boston and much of the southern region should see a shift in the weather pattern as a strong southerly flow builds heat across the region amid a mix of sun and clouds — pushing temperatures into the mid-80s, with a few spots closer to 90 farther out from the city.

Fragments of energy from yesterday’s system will continue to linger in northern New England today, creating scattered showers throughout the day.

Depending on how much surface heating the region receives, a marginally unstable atmosphere could lead to isolated or scattered showers in the area, primarily around noon and into the afternoon. Showers should move in quickly, and there is a good chance that Boston will remain dry for most of the day. Rainfall totals will be a quarter inch or less.

This broad pattern will bring humidity back to muggy conditions with dew points reaching the high 60s and low 70s today and lasting through the rest of the work week. A handful of heat index readings could top 90 degrees today.
