Nashville, Tennessee – A stretch of chilly, soaking rain is shaping up across Tennessee ahead of St. Patrick’s Day, with daytime temperatures largely holding in the upper 40s and 50s between March 11 and March 17.
According to the National Weather Service Climate Prediction Center, Tennessee falls within a 40-50% probability zone for above-normal precipitation during the 8-14 day period. Temperatures are projected to trend near to slightly above seasonal averages statewide, which should keep most precipitation falling as rain rather than snow across lower elevations.
In Nashville and along the Interstate 40 corridor, multiple systems tracking through the Mid-South could bring periods of steady rainfall. Daytime highs near 50 degrees will create a damp, raw feel, especially when combined with occasional breezy conditions. In Memphis and along Interstate 55, similar conditions are expected, with reduced visibility possible during heavier rain bands.
Across eastern Tennessee, including Knoxville and Chattanooga, cooler overnight lows dipping into the mid-30s may briefly flirt with a rain-to-snow mix in the highest elevations of the Smokies during pre-dawn hours. However, widespread accumulation appears unlikely outside the highest peaks.
Motorists statewide should prepare for ponding on roadways and slower commutes during steadier rainfall, particularly along Interstate 24 and Interstate 75 corridors. Additional updates are expected as the March 11-17 window approaches and system timing becomes clearer.
