KEY MESSAGES

Updated at 210 PM EDT Sun Jul 5 2026

- Scattered showers and thunderstorms will continue this afternoon.

- Storm chances off and on through this week, not a total washout any particular day.

DISCUSSION

Issued at 210 PM EDT Sun Jul 5 2026

This afternoon and early evening showers and storms will be scattered as a trough moves into the Ohio Valley centered near IL/IN this afternoon. Radar is already getting active with scattered storms over the Cumberland Plateau and isolated development elsewhere across the region. A Marginal risk for severe can be expected today with good instability in place with CAPE around 2k J/kg this afternoon. Gusty winds will be the primary threat in stronger storms. With a high freezing level, large hail will be more difficult to achieve. Heavy rain can also be expected locally with PWat values close to 2 inches and weak steering flow. CAMs suggest that showers and storms will dissipate this evening, maybe even early evening and the overnight period will be quiet.

A trough will be over the Ohio Valley early this week bringing widespread showers and storms mainly in the afternoon/evening hours. A stationary boundary may also be over the region Mon/Tues contributing to the lift. A few strong storms will be possible but the region is not outlooked for a severe threat. By Thu/Fri, a broad trough will be over the Eastern U.S. Widespread mostly diurnal thunderstorms seem likely for late in the week into the weekend. Temperatures will be near normal this week in the upper 80s and near 90.
