Happy Monday, East Tennessee!
As your local meteorologist, I’m bringing you the latest weather update for Monday, June 30, 2025. After a weekend of afternoon storms primarily along higher elevations, we’re gearing up for broader rainfall and storm coverage over the next two days as a trough digs in and pushes a cold front through the region.

Monday: A Warmer Start with Rising Rain Chances
Today kicks off warmer than Sunday, with morning temperatures in the 60s and 70s and higher humidity adding a sticky feel. We’ll see highs climb to the upper 80s to near 90°F—right on track for late June—though the heat index will push into the mid to upper 90s due to that elevated moisture. As the cold front and trough approach, rain chances will increase slightly today, but not every area will see precipitation. Keep an eye on the skies, especially if you’re heading out, and use the eastTNweather app for real-time radar updates!

Tuesday: A Cold Front Brings Widespread Storms and Flood Risks
The weather shifts Tuesday, July 1, as the cold front moves through, boosting rain coverage across East Tennessee. With a water-loaded atmosphere, expect downpours that could spark localized flood concerns, so stay cautious in low-lying areas. Highs will dip to the mid to upper 80s, and showers and storms will persist throughout the day. Grab your umbrellas and track the action with the free eastTNweather app—your essential tool for staying ahead of the weather!

Post-Front Outlook: Drier Air and 4th of July Prep
Behind Tuesday’s cold front, drier air and a ridge of high pressure will settle in, reducing rain chances and making the air feel a bit more comfortable. This dry spell will be short-lived, lasting just a day or two. As we approach the 4th of July on Friday, July 4, humidity will climb again, pushing the heat index near 100°F. There’s a slight chance for isolated storms, but significant rain isn’t expected through the holiday weekend (July 3-6, 2025). This hot, humid setup is ideal for 4th of July celebrations, whether you’re hitting the lake, pool, or enjoying other festivities in Knoxville, Chattanooga, or the Smokies.
