Nashville, Tennessee – Temperatures will surge into the lower 90s by Thursday afternoon, delivering a summerlike stretch of heat that will quickly dry out conditions across Tennessee heading into the weekend.
According to the National Weather Service and NOAA’s Climate Prediction Center, Tennessee is in an 80 to 90 percent probability zone for above-normal temperatures from April 16 through April 20, with a “much above normal” core intensifying between Saturday and Monday. A strong heat dome over the Southeast will suppress rainfall and allow temperatures to climb several degrees above seasonal averages.
In Nashville and across Davidson, Williamson, and Rutherford counties, highs are expected to reach 89 to 92°F between 2 p.m. and 6 p.m., with overnight lows holding in the upper 60s. Along the I-40 and I-65 corridors, dry air and prolonged sunshine will accelerate vegetation drying, increasing wildfire risk in grassy and wooded areas.
Memphis and West Tennessee will see highs in the upper 80s to near 91°F, while Knoxville and eastern Tennessee will climb into the upper 80s with similarly dry conditions. Chattanooga could approach the low 90s during peak afternoon heating, especially from Saturday through Monday when the heat intensifies.
The precipitation outlook shows a 33 to 50 percent chance of below-normal rainfall statewide, reinforcing dry ground conditions and increasing the likelihood of fire starts. Burn restrictions may be considered if the pattern persists.
Residents should avoid outdoor burning, stay hydrated, and limit strenuous activity during peak afternoon heat. Drivers should monitor vehicle temperatures and avoid parking on dry grass to reduce fire risk.
The most intense heat is expected April 18 through April 20, when the core of the “much above normal” zone settles over Tennessee. Additional advisories are likely as hot, dry conditions continue into early next week.
