Low-amplitude short-wave trough is ejecting across the Ohio Valley.

SPC Feb 26, 2025 Day 4-8 Severe Weather Outlook
Day 4-8 Outlook Day 4-8 Convective Outlook NWS Storm Prediction Center Norman OK 0354 AM CST Wed Feb 26 2025 Valid 011200Z - 061200Z ...DISCUSSION... Severe weather potential will be low to start the period with northerly flow across the Gulf on D4/Saturday. On D5/Sunday, a compact mid-level low will translate east across the Southwest which will result in lee cyclogenesis in the southern/central High Plains. As surface high pressure across the Midwest translates east, favorable low-level trajectories and strengthening flow across the Gulf and southern Plains will initiate significant moisture return across Texas. The initial mid-level low will weaken

A few isolated thunderstorms are possible across the northern/central Plains this evening. Severe thunderstorms are not anticipated. ...01z Update... Modifications were made to thunder to account for ongoing thunderstorm activity across South Dakota and Nebraska and to remove thunder chances across Colorado. As a shortwave impulse continues eastward this evening, cooling aloft and steep lapse rates will allow for sufficient instability for a few additional thunderstorms to develop
