DISCUSSION
Issued at 135 PM EDT Wed Mar 18 2026
Currently we've crossed back above the freezing mark today with more southwesterly flow near the surface. Weak disturbance is moving overhead, but the dew point depression this afternoon is 20-30 degrees meaning that anything other than light drizzle is unlikely, but a few people in southeast TN could get a quick spit of rain. We should remain above freezing for most locations outside of the mountains and southwest Virginia tonight, and remain above freezing for at least the next 7-days.
Temperatures really begin to warm back up starting tomorrow when the sun will try and make it's return to the region. We'll continue the warm up through at least Sunday, which is forecasted to be the warmest day of the week with highs looking to eclipse the 80 degree mark for the central and southern Tennessee Valley.
We'll get a cool down to end the weekend as a slow moving front dips down from the north. Still some model discrepancies with how far west and south the heavier precipitation will extend along this front trying to fight against the strong southwest ridge. Temperatures will remain well warm enough that any precipitation will fall as rain, and as of now the dynamics don't look particularly impressive for severe weather. Temperatures to start of next week will be cooler, back to near seasonal normals.
