Isolated supercell development may persist in a narrow corridor across northeastern Nebraska into southwestern Minnesota through mid to late evening before diminishing. ...01Z Update... ...Mid Missouri Valley... Mid-level heights continue to build across much of the northern Rockies and Missouri Valley into Upper Midwest. Primary forcing for ongoing convective development appears to lift associated with weak lower/mid-tropospheric warm advection, along and east of weak northern Great Plains surface troughing. Low-level moisture return has remained rather modest (with maximum surface dew points still in the mid/upper 50s F) and confined to a narrow corridor, but this appears to be contributing to CAPE on the order of 1000-2000 J/kg. The onset of radiational surface cooling, coupled with warming aloft, probably will result in rapidly increasing inhibition within the next couple of hours. This should be accompanied by diminishing convective trends, but it is possible that this could be slowed somewhat by forcing on the nose of a nocturnally strengthening low-level jet. ...Southern Appalachians... As a remnant lower/mid-tropospheric mesoscale convective vortex migrates north-northeastward across northwestern Georgia into the southern Appalachians, modest clockwise-curved low-level hodographs are developing across the Piedmont of eastern Georgia into South Carolina. This is where a recent increase in thunderstorm development is ongoing in the presence of a seasonably moist boundary-layer characterized by sizable CAPE. With the surface dew points in the lower 70s enhancing low-level buoyancy and potential near surface upward accelerations, an isolated tornado may not be out of the question, before forcing spreads into cooler/more stable air. ..Kerr.. 05/25/2026 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
