Another round of heat and humidity has forecasters issuing a Heat Advisory for the Bangor area.

The National Weather Service is warning of another big return of hot and humid conditions throughout Maine. A Heat Advisory has been issued for the Bangor area, as temps climb into upper 80s and low 90s Thursday. Combined with the humid conditions, heat index values will climb into the upper 90s throughout the afternoon. According to the NWS, "heat index" is defined as "what the temperature feels like to the human body when relative humidity is combined with the air temperature."

Relief from the heat and humidity comes as a cold front will cross the state Thursday night. Forecasters say "Ahead of the front scattered showers and thunderstorms will develop this afternoon into early this evening. The thunderstorms that develop will contain dangerous cloud to ground lightning, torrential downpours, and the potential to produce strong/gusty wind."

More comfortable and dry weather settles into the state Friday, through the weekend.

The Maine CDC recommends those without air conditioners to keep windows and blinds closed on the side of your home with the most sun, and open on the shady side. At night, open all windows and run fans to let the cool air in, and hot air out. For more tips to avoid heat-related illness, visit
