Forecast: Summer-Like Weather Lingers Well Into Fall

Meteorological autumn arrived on Sept. 1, marking the 90 days between the warmest and the coldest seasons of the year. Typically we would find mild days and crisp cool nights during this period. However, this year is continuing a trend of milder-than-average fall temperatures.

A cold front passed off the coast overnight and now less humid air is arriving from the west. It's still muggy this morning, but the 70-degree oppressive humidity is being shunted out to sea.

Temperatures today will reach around 80 degrees east of Route 495 and stay in the 70s west of there. Cape Cod will also remain in the 70s. These temperatures are 10 to 18 degrees above average and more typical of early to mid-June.

Finally, tonight will be a night that's cool and pleasant for sleeping. With low dew points and mainly clear skies, many areas should dip down into the 50s.

A weak weather system creates an increase in clouds Wednesday. It will be a day that's partly sunny, with most of the sunnier side of things occurring in the first half of the day and clouds coming later in the afternoon. A sprinkle Wednesday night is about all we can expect, and while we did receive some rain Monday and Sunday, we need a lot more.

The pattern continues to be not only warm but also dry. And, after the drought of 2016, it would be very unhealthy for trees and shrubs to enter winter this dry. We shall see.
