Hazardous Weather Outlook Issued For Connecticut

CONNECTICUT — The National Weather Service has issued a hazardous weather outlook and heat advisory for the entire state, as it will feel as hot as 100 degrees on Thursday and Friday.

Additionally, an air quality action day has also been issued for most of the state, which means that the "Ground Level Ozone within the region may approach or exceed unhealthy standards."

"The strongest late-week heat wave will focus on New England and upstate New York, where new marks for the highest temperatures of the year are likely to be set, including Albany, New York, and Hartford, Connecticut," according to Accuweather.com. "Hartford is expected to soar to 99 degrees, a mark that would surpass the top high temp there this year -- 97 degrees on July 20 -- and easily best the daily record of 96 degrees set in 1944. The average high in Hartford at this time of year is 84 degrees." (Read more at Accuweather.com)
