Scattered severe thunderstorms with large to very large hail, damaging winds and tornadoes are expected tonight across parts of the southern/central Plains to Lower Missouri Valley. A couple of strong tornadoes and hailstones up to 2-3 inches in diameter are possible. ...01Z Update... A prominent shortwave trough now nearing the Colorado/Kansas border is promoting elevated convection ahead of it. An 8.2 C/km mid-level lapse rate was sampled on the 00Z DDC sounding this evening. These steep lapse rates should shift eastward along with the shortwave trough. Additional, stronger convection remains possible in parts of central/eastern Kansas into northern Oklahoma. Earlier convection has complicated the low-level thermodynamic environment, though large hail and damaging winds are possible with organized cells and linear structures. The tornado threat through the evening is somewhat less clear, but a deepening surface low should advect richer moisture northward. Depending on storm mode and low-level stability, tornadoes remain possible in parts of northern Oklahoma and south-central Kansas later this evening. In the short term, the greatest threat for a strong tornado is in southeast Kansas. In Oklahoma into North Texas, the dryline is surging westward. This area will become increasingly removed from large-scale ascent. An isolated storm or two remain possible at least trough mid-evening. Lastly, convection in Missouri and southeast Kansas will eventually grow upscale. A buoyancy gradient within the Mid-South region may serve as a focus for continued southeast movement through the evening. Marginal wind and hail are possible with this activity. ..Wendt.. 04/27/2026 $$ = = = To unsubscribe from WX-STORM and you already have a login, go to https://lists.illinois.edu and use the "Unsubscribe" link.
