Blistering temperatures will hardly relent as the Fourth of July holiday weekend approaches with daily highs near 100 and a forecast for the heat to stay above 90 through Monday. A heat advisory has been issued for Southeast Tennessee, North Georgia and Northeast Alabama, according to the National Weather Service. The advisory in Tennessee extends through Thursday and Friday, when the high in Chattanooga is predicted to reach 98 and 97 degrees, respectively. A heat dome occurs when a persistent region of high pressure traps heat over a particular area, and it can linger for days to weeks, according to the weather service. Heat domes are typically linked to the behavior of the jet stream, which can cause the sun to create progressively hotter temperatures on the ground. Read the full story at the link in our bio.
