Relief coming for Boston in day five of summer heat wave
Temperatures hit the 90-degree mark in Boston before noon today marking day five of this summer’s second heat wave.
The thermometer registered 90 at Boston Logan International Airport at 10:37 a.m., making it official, and climbed to 94 degrees by mid-afternoon.
The last time Massachusetts had five consecutive days of over-90 degree weather in July was 1990, according to meteorologist Charles Foley at the National Weather Service in Taunton.
But relief is expected soon.
“We don’t expect temperatures exceeding 90 degrees Monday,” he said. “This should be the fifth and last day of the heat wave.”
Thunderstorms struck the Springfield area around 3 p.m., according to meterologist Benjamin Sipprell of the National Weather Service.
One-inch hail was reported in Belchertown, and a fire was reported at a house on 35 Round Hill Road in Kingston after a lightning strike, Sipprell said. No injuries were reported at the scene, according to Kingston police. No other damage was reported.
Temperatures are expected to drop Monday to the mid- to high 80s, where they are expected to stay throughout the week, with a chance of showers and isolated thunderstorms each afternoon, according to Foley.
Because of the moist air mass that has traveled from the Gulf and settled over Greater Boston this past week, some of those showers may turn into downpours.
“That’s because air normally associated with Miami or New Orleans or Havana has settled up here in southern New England,” Foley said.
He added that the dewpoint, which is a measure of moisture in the air, will remain at 70 degrees as it has during the preceding days of the heat wave.
“A dewpoint of 70 is categorized as oppressive conditions,” Foley said. “There is a very humid air mass over us right now so even though blazing temperatures are expected to end, we’ll have bad humidity into next week.”
Communities south of Boston including Quincy, Taunton, and Brockton felt the worst of the heat t0day because of cloudless conditions, while ocean winds will kept the air cooler around Cape Cod and the islands, where temperatures hovered in the high 80s.Alyssa A.
