Other severe thunderstorms are expected across parts of the Midwest and Great Basin. 20Z Update The forecast remains on track, and only minor adjustments were made with this update. The ENH risk was expanded slightly southeastward in southwestern NE. Here, diurnal heating amid lower 60s dewpoints will yield a corridor of moderate surface-based buoyancy, which combined with 50-60 kt of effective shear, will support the potential for a couple intense supercells capable of producing very large hail and severe gusts. The adjacent SLGT risk was also expanded southeastward into south-central NE and north-central KS, where upscale-growing clusters will pose a risk for severe wind gusts with time. The SLGT risk in eastern NM was expanded westward toward the higher terrain, given the potential for initially discrete supercell structures capable of producing large hail. Finally, a CIG1 wind area was added over portions of the Great Basin, where a deeply mixed boundary layer and increasing buoyancy may support some gusts upwards of 75 mph.
