A cold front is expected to move into Massachusetts this afternoon, ending a week-long heat wave, according to the National Weather Service.
Some thunderstorms will likely hit scattered parts of the state this afternoon as well, said Bill Simpson, meteorologist with the agency in Taunton.
By Sunday, “it’ll be noticeably less humid,” Simpson said, and temperatures will return to seasonal averages through Thursday, remaining in the lower 80s. Temperatures may rise again late next week, but a second heat wave is unlikely.
On Friday, Boston broke a record with a high of 99 degrees. Today’s high is expected to be 96 degrees—lower than the record high of 99 degrees.
The service issued a warning from mid-afternoon until 9 p.m. for extreme thunderstorms and hail that could be as large as an inch.
Bostonians have fared well through the heat in general. A spokesman for Massachusetts General Hospital said only one person was admitted to the emergency room for heat-related reasons; at Boston Medical Center’s emergency room, two people were admitted for heat issues, according to a spokeswoman.
Nine people were transported to emergency rooms for heat-related issues—none serious—Friday and four so far today, according to a spokesman for the city’s emergency medical services.
“Most people are just suffering from dehydration and some mild weakness,” said Nick Martin, director of communications for the city’s public health commission.
Boston has deployed additional emergency medical service teams throughout the city.
In Connecticut, a man died of heatstroke at Hartford Hospital this week, said Dr. A.J. Smally, who treated the patient.
“Even with the best treatment, people sometimes come in a little on the late side,” he said. People often miss initial symptoms of heatstroke—which include confusion and disorientation.
Smally said victims of heatstroke need “intensive treatment” within an hour or two. He said he could not release the age of the patient, but said the death was “very out of the ordinary.”
The Boston Housing Authority is making door-to-door visits to remind disabled people and the elderly to find cool places to stay, including local cooling centers. Those centers are also open today for youth and families. Hours vary but are listed on the housing authority’s website.Sanjena Sathian can be reached at firstname.lastname@example.org.
