Don’t even think about packing up those air conditioners just yet. After Boston experienced its hottest day of the year Monday, the next two days could also bring scorching temperatures.
“Right now we forecast a high of 95 for Boston,” on Tuesday, said National Weather Service meteorologist Hayden Frank on Monday. The record for the day is 95 degrees, Frank said, and if Boston reaches it, there will be an alert from the service.
On Wednesday, highs are expected to be in the low 90s, Frank said. The record for that day is 91 degrees.
Humidity will be high for both days, Frank said, and though it will be cooler at night, lows by daybreak will still be in the lower 70s.
On Monday, temperatures reached 93 degrees at Logan Airport. So far, Boston has seen 12 days this year with 90-degree weather.
The record high for September is 102 degrees reached in 1881, Frank said.
“Here we are in September, and it’s going to feel more like July,” said Kim Buttrick, a weather service meteorologist. She said that it could be the beginning of a short heat wave if temperatures reach at least 90 degrees three days in a row.
The city of Boston sent out a heat advisory as the temperature reached 91 degrees just after 2:30 p.m. Mayor Martin J. Walsh reminded residents in a statement to be vigilant about recognizing signs of heat exhaustion and to never leave a child or pet alone in a car.
As temperatures rose Monday afternoon, a rush of weekend vacationers returning from Cape Cod caused traffic to snarl on the Sagamore and Bourne bridges. Traffic was backed up 8 miles on Route 6 westbound before the Sagamore Bridge, according to state Trooper Dustin Fitch. Cars driving north on Route 28 were backed up 1 mile before the Bourne Bridge, Fitch said.
High temperatures were in the low 90s across the region on Monday, Buttrick said.
A southwest wind blowing at 10 to 20 miles per hour kept South Coast highs in the mid- 80s.
After the expected scorchers the next two days, some relief may be on tap for Thursday, with partly cloudy skies and highs in the low to mid-80s. Showers and thunderstorms will develop in the afternoon and could stall over the region through Friday morning, Buttrick said.
“We’re still in this dry spell,” Buttrick said. “Our next chance for measurable rain comes on Thursday.”
Highs will be more seasonable on Friday. Temperatures will average in the upper 70s statewide, Buttrick said.
