Before Memorial Day is potentially impacted by a soon-to-be tropical storm, a few thunderstorms could pop up in the midst of a possible heat wave on Friday.
Temperatures have reached 90 degrees for two consecutive days at Bradley International Airport in Windsor Locks. If Friday becomes the third, it would make the first heat wave of the year.
Meteorologist Scot Haney said the million dollar question is whether temperatures will go that high.
"It all depends on cloud cover," Haney explained. "There is certainly the potential for 90 degree heat if we get enough sunshine. While it's mostly cloudy out there right now, we should have a mix of clouds and sunshine for much of the day."
Still, an air quality alert has been issued for most the state. That means it could be hazardous for sensitive groups of people to be outside.
All counties, except southern Fairfield, southern New Haven and southern New London, are under the alert from 11 a.m. to 11 p.m. on Friday.
"Temperatures will rise well into the 80s at the very least," Haney said. "Dew point readings will likely reach the low and middle 60s and you'll notice the higher humidity."
There's also the chance for a few pop-up thunderstorms during the afternoon hours. However, Haney said many towns will not see one.
Friday night is expected to be muggy but mild with lows in the 60s.
"The heat and humidity will peak [Saturday]," Haney said. " Temperatures will reach the 80s and lower 90s and dew points will be in the 60s."
That could be record territory.
The record high for the greater Hartford area for May 28 is 93 degrees, which was set in 1977. For Bridgeport, it's 90 and it was set in 1991.
While it'll be close for Hartford, a record is not expected for Bridgeport, according to Haney.
Friday's thunderstorm potential will play out for Saturday and Sunday.
A cold front will stall in area over the weekend, but it'll only tone the heat and humidity down slightly, according to Haney.
"With the front nearby, showers and thunderstorms are possible, but again, our weather will be dry the majority of the time," he said.
Memorial Day on Monday is tricky to forecast as of Friday afternoon.
"It's starting to look a lot cloudier and a lot wetter," Haney said. "That's because of a tropical disturbance (which may become Tropical Storm Bonnie) way down to the south of Connecticut. It's out over the open waters of the Atlantic hundreds of miles east of Florida at [the 1 p.m.] hour. While we're not going to take a direct hit from this storm here in our state, it now appears that plumes of moisture will be advancing into the region on Monday."
