Today marks the end of July and what will go down in the record books as the third warmest July in Boston’s recorded history, with the average monthly temperature running about 3.5 degrees above normal.
Not only will July 2022 be in the top five for warmest temperatures, we’ll also finish in the top five—likely fourth—for driest ever, with Boston receiving only about 0.62 inches of rain per all month (average is 3.27 inches).
High pressure will provide the region with another very warm and mostly sunny day. A few high and thin clouds will dim the sun later this afternoon in the south as a system approaches the area from the southwest, which will eventually bring wetter conditions to start the new work week as winds return to many from the southwest during today. Highs today reach the mid 80s inland, mid 80s along the coast.
Overnight clouds will increase along with humidity as we enter a southerly air flow. A few showers will break out along the South Coast late tonight and continue across the Cape and Islands until midday on Monday, but should clear by mid to late morning. Lows tonight in the upper 60s, highs Monday in the mid to upper 80s.
Hot and humid Tuesday with clouds and sun. A weak frontal system will bring some showers and thunderstorms, mainly in central and northern areas. After a brief respite from Wednesday’s heat and humidity, we return to an unseasonably hot Thursday with temperatures heading into the 100s, prompting us to put a first alert stamp on Thursday.
