Hot Saturday evening out
It will remain hot into the evening with temperatures staying around 90 until about 7:00PM EDT in Chattanooga. Most people will remain dry, but there will be a few spotty storms across the area. Storms are more likely to pop-up in the higher elevations and south of Chattanooga until about 8:00PM EDT tonight.
For any fireworks shows tonight, sunset is at 8:59PM EDT. It will be in the low 80s by dark for the fireworks. Any spotty storms should be done before then, making for a warm but pleasant night for festivities. Overnight lows will be in the mid to upper 60s outside of the city and around 70 in Chattanooga with a partly cloudy sky.
