New England Swelters: Summer Heat Arrives Early

A warm front is set to bring unseasonably warm weather to the region starting Monday, with southwesterly breezes making it feel quite windy, especially over Cape Cod and the islands. Temperatures are expected to reach the upper 60s, though coastal areas will remain cooler. Scattered showers are possible but likely to be brief and light.

Tuesday will see temperatures climb further into the 70s and low 80s across much of the area. However, eastern Essex County, the Cape, and the islands will experience cooler readings, with some coastal areas potentially in the low 50s due to onshore flow.

Wednesday is predicted to be similarly warm, with some interior locations south of the Mass Pike possibly reaching the mid-80s. A slight chance of an afternoon shower exists if atmospheric instability increases. Overnight temperatures will remain mild, near 60 degrees, allowing for open windows, though tree pollen levels are significantly increasing.

Looking ahead to Thursday and Friday, warmer-than-average temperatures are anticipated, though the influence of marine air could alter forecasts. Forecasters caution that wind direction shifts can dramatically impact predicted temperatures, making long-range predictions beyond midweek uncertain.

An early outlook for the Boston Marathon on Monday, April 20, suggests that the current warm spell will have ended, with cooler conditions likely.
