Dozens of schools across the state sent students home early Tuesday as temperatures reached record highs, and many dismissed early again today.
While temperatures are expected to come down a bit, humidity levels will increase a bit, making the apparent temperature or heat index even higher.
As of 6:45 a.m., there are more than 40 early dismissals.
The mercury climbed to 94 degrees in Bridgeport on Tuesday, breaking the Sept. 8 record of 90, which was set in 2010, and sliding into second place for the warmest September temperature on record.
The temperature reached 96 degrees in Windsor Locks, breaking the day's record of 95 in the Hartford area, which was set in 2007.
It's the first time the hottest day of the year has fallen in September, or outside of the meteorological summer, since 1983, according to First Alert Meteorologist Ryan Hanrahan.
Heat waves in September are unusual. If the mercury reaches 90 degrees on Wednesday, this will be the first September heat wave in Connecticut since Sept. 7, 1983.
