As our late spring scorcher continues, temperatures are expected to reach the upper 90s today with high humidity and could approach 100 tomorrow west and south of Boston.
"We are expecting record-breaking heat tomorrow," said Kim Buttrick, a meteorologist with the National Weather Service in Taunton. Forecasters expect a sea breeze to temper tomorrow's heat slightly along the coast, with a predicted high in the low 90s. But if the breeze lags, the mercury could soar to historical heights.
"If that does not materialize, Boston could break the record" of 96 degrees in 1984, she said. Today's record high is 97, also set in 1984.
The culprit is a high-pressure system sitting off the mid-Atlantic and spinning unseasonably warm air toward New England. The normal high for this date in the Boston area is a comfortable 75 degrees.
The temperature today is expected to hit 93, but with an elevated dewpoint that makes the air heavy and the sweat slow to evaporate.
"It will feel like 100 degrees," she said. "We're not in Georgia or Alabama, but it's hot for us in New England," she said.
The hot, hazy weather has caused ground level ozone concentrations to rise, and the Environmental Protection Agency has issued an air quality alert today until 10 p.m. The National Weather Service has also issued a heat advisory for parts of Connecticut.
The heat wave will continue Tuesday, but relief is expected late in the day, with a cool front carrying drier air cutting through the clamminess.
"It will still be in the mid-80s, but it will feel a lot cooler," she said.
