Our last weekend of astronomical summer is beautiful with sunshine and highs today and Sunday in the 60s with afternoon sea breezes.
Dewpoints have dropped and that means some colder temps too. Lows reach the 40s in the suburbs, with some 30s to upper 20s across the north country tonight. Some places far north in Vermont, New Hampshire, and Maine have either a frost advisory or a freeze warning for Sunday morning. Bring in your plants, or cover your sensitive flowers before bed tonight.
Boston should stay mild in the upper 40s. The average first frost/freeze for Boston is November 5. Something else to keep in mind, we have an elevated wildfire risk today due to the combination of dry terrain, low relative humidity and gusty winds.
Our temperatures increase for next week with highs in the 70s for the Autumnal Equinox on Monday. Our first full day of fall on Tuesday will actually feel like summer again with highs around 80 degrees. Scattered showers will move in for Wednesday as a cold front heads into the northeast. At the same time, Hurricane Gabrielle will be way offshore and making an important turn to the northeast and out to the northern Atlantic. Our only impacts locally will be some beach erosion, rip currents, and rough surf Monday into Tuesday.
When does fall foliage start?
The fall foliage is starting to appear more across the northeast with low color reported in higher elevations of northern Vermont, New Hampshire and Maine. The trees are quite stressed right today due to the expanding drought conditions. So we anticipate a quick and early peak foliage season compared to normal. For reference, our partners at Explore Fall have the average peak for Boston around late October, so it’s possible we will see the peak in mid-early October.
