Following two days of humid heat, temperatures will continue to hover in the 90s today in Boston, marking the first official heat wave of the season, according to the National Weather Service.
“Tuesday will almost be a carbon copy of yesterday’s weather,’’ said meteorologist Alan Dunham.
Today will see slightly cooler temperatures than Monday’s 95-degree high, but only by a degree or two, he said.
As morning clouds dissipate, Massachusetts will see mostly sunny skies, followed by localized thunderstorms around the state in the afternoon, Dunham said.
Expect rain to be intense, lowering visibility in the afternoon for commuters. These downpours could produce some flooding, but nothing widespread. Western Massachusetts could also see some small hailstorms today, although the heat will make it difficult for hail to form, according to the weather service.
Wednesday and Thursday will stay hot, but not quite as sweltering, with temperatures dropping to the mid-80s. Friday will see highs in the low 80s.
Isolated showers and thunderstorms are likely every day through the weekend, although Friday will see the greatest chance of precipitation. Highs will also be in the low 80s Saturday and Sunday.
The official definition of a heat wave is three days with temperatures of 90 or more.
