Other severe storms are expected across portions of New England. 20Z Update The forecast remains on track, and only minor changes were made with this update. The SLGT risk in the central High Plains was expanded southeastward from southeast CO into southwest KS and parts of the OK/TX Panhandles. Guidance is in relatively good agreement, depicting thunderstorms evolving off the Raton Mesa and tracking east-southeastward along a gradient of rich boundary-layer moisture/moderate surface-based buoyancy this evening/tonight. Aided by 40 kt of effective shear and increasing low-level hodograph curvature amid a strengthening nocturnal LLJ, supercell clusters will pose a risk for severe gusts, large hail, and possibly a tornado. Farther east, a minor westward expansion of the SLGT risk was made into north-central OK. Ample diurnal heating/destabilization of a very moist air mas (middle/upper 70s dewpoints) is yielding strong surface-based buoyancy along an east/west-oriented surface boundary. Current thinking is that a few organized clusters/supercells developing along the boundary will be capable of producing severe wind gusts and large hail later this afternoon/evening.
