Forecast: Cooler Today With Highs In 70s Before Warm-Up

This article is more than 5 years old.

A basically sunless Sunday was also mostly dry along with seasonable temperatures. Now we are looking at a prolonged stretch of warm and dry weather on the way which likely takes us into the weekend.

This anomalous pattern is going to set up September 2015 to be one of the top 10 warmest Septembers on record. It remains to be seen just how high on that list we end up, however. The warmest September ever was in 1983.

Today there is a weather system passing over New England, and this will keep temperatures cool and also allow some build-up of cloudiness, especially this afternoon. Highs will reach the lower 70s.

As this system dissipates on its way to Canada, warm and, at times, somewhat humid air mass will follow. Temperatures the rest of the week will reach the 80s, and there is even a chance of some record heat before this particular pattern ends. High pressure is going to keep any storms and, in some cases, any clouds from reaching New England.

High pressure is a region where the air is sinking from above and warming at the same time. As the high sits in the eastern part of the country, it will become warmer and warmer each day. Of course, the length of daylight is rapidly decreasing so it becomes more difficult to reach 90 degrees this time of year, but 80s are likely after today for quite a while. With temperatures like that, it's no surprise September 2015 is possibly one for the record books.

Today: Partly sunny and breezy. Highs 71-75.

Tonight: Mostly clear, with a low around 55.

Tuesday: Sunny, with highs 80-84. Cooler at the coast

Wednesday: Sunny, with highs 80-84. Cooler at the coast.

Thursday: Sunny and warm, with highs in the lower to mid 80s. Cooler on the Cape.

Friday: Sunny, with a high near in the mid 80s. Cooler at the beaches.
