HARTFORD, CT (WFSB) -

Wednesday was the hottest day of the year as the state wades further into a potential heat wave.

The Department of Energy and Environmental Protection's air quality alert remained in effect for Fairfield, Middlesex, New Haven and New London counties from 11 a.m. to 11 p.m.

Temperatures surpassed 90 degrees on Wednesday, according to Chief Meteorologist Bruce DePrest who said it was the hottest day of the year.

He said a heat wave consists of three consecutive days of temps in the 90s.

"Fortunately, the humidity today wasn’t too bad. Therefore, the heat index, which is a measure of what you feel due to the combination of heat and humidity, remained below the 100 degree mark," DePrest said.

Wednesday night will be another uncomfortable night for sleeping.

DePrest said the dew point will creep up overnight to the upper 60s to the lower 70s.

Due to the increasing humidity, areas of fog will develop on Wednesday night and last through the early morning hours.

Thursday is expected to bring 90 degree temperatures again, but the humidity will be higher.

"The heat index on Thursday, which takes into account the temperature and humidity, will likely reach the 90s in many towns," DePrest said.

A cold front will help lower the humidity on Thursday night, but there may be some strong storms ahead of that.

DePrest said isolated severe thunderstorms are possible "with the greatest threat being torrential downpours, cloud to ground lightning, and gusty (perhaps damaging) winds."

There is a low risk of a tornado.

The air will be a little drier for Friday.
