DISCUSSION...Low-level moisture continues to stream northwestward late this evening into portions of the TX Permian Basin region. Meanwhile, WV and IR imagery suggests that ascent related to the deep upper-level trough over the Southwest is beginning to overspread the region. While timing remains uncertain, storm development will become increasingly likely overnight, especially near/north of a southward-moving cold front. Steep midlevel lapse rates, MUCAPE increasing into the 1000-2000 J/kg range, and effective shear of 40+ kts will support elevated supercell potential, with an attendant threat of large hail in the 1.5 - 2 inch diameter range.=20 Severe-storm coverage remains somewhat uncertain overnight and could remain rather isolated, but eventual watch issuance is possible given the potential for elevated supercells. ...Dean/Hart.. 04/09/2024 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!_X9XNTdF8W9wEj8opaW-DaGKmQ0xZS_elGxPJQko16FxG2SxW86oCBqTzUeRfIv4hMXGDRs03= fACkmTFP2-anEB049g$ for graphic product...
