CT Weather: It Will Feel Like 100 Degrees Today, Wednesday

The National Weather Service has issued a Hazardous Weather Outlook for all of Connecticut through Wednesday evening as the heat index will be a real cause of concern for anyone who has to spend any amount of time outdoors. A Heat Advisory is in effect for the entire state, except for Hartford County, which is under an Excessive Heat Warning as it may feel in excess of 105 degrees today.

The oppressive heat is expected to break Thursday but that means there is a decent chance for thunderstorms to roll through. And there is some good news about the upcoming Labor Day holiday weekend forecast. It now appears that Sunday and Labor Day will be partly sunny and dry, while Saturday looks to be mostly cloudy but largely dry too.
