Logan Airport broke 80 degrees before noon Wednesday as the air heated under hazy skies prompted by wildfire smoke drifting in from Canada. Boston didn’t get close to the daily record of 96 degrees set in 1925, but the thermometer did top out in the mid-80s. The heat is set to ramp up with Boston likely reaching the 90s Thursday afternoon under mostly sunny yet hazy skies. The humidity will increase as well, sending dew points into the 60s, making the air feel heavy.
