DISCUSSION

Issued at 216 AM EDT Mon Mar 23 2026

A cold front moving across the OH VAlley tonight will move across our area Monday morning, between 09Z and 15Z. There is currently a lot of convection along the front, but this is expected to decrease as it approaches our area. Dynamics with upper trough and jet will be mainly north of our area, and a line of weakening showers with a few elevated thunderstorms will move across southwest Virginia and northeast Tennessee. Only light amounts between a tenth and a quarter inch are expected. Mountains may see wind gusts near 40 mph at times tonight ahead of the front, which is covered by the Wind Advisory.

A colder air mass will build into the area behind the cold frontal passage. High pressure over the Great Lakes and OH Valley region will promote drier and seasonally cooler conditions through Tuesday. By Wednesday, broad ridging will expand from the southwest with high pressure shifting eastward, leading to a return of southerly flow and warming temperatures. The main concern midweek will be the low afternoon relative humidity in the 20s/30s. Besides some light showers across southeast Tennessee Wednesday, mostly dry conditions with near seasonal to above normal temperatures anticipated.

Rain chances return late in the week as a front crosses the TN/OH Valley region from north to south. The upper level dynamics weaken as the system moves into the region. Moisture from the Gulf is limited due to persistent E-W surface ridging across the Gulf coast states. Scattered showers are expected but mainly north of interstate 40. Surface ridging and dry northwest flow aloft returns for next weekend.
