A watch may be needed if trends suggest sufficient storm coverage is likely. DISCUSSION...Elevated thunderstorms continue across far southeast NM and the TX South Plains amid persistent warm-air advection to the north of a surface low centered over the Pecos County TX vicinity. Large hail will remain possible with these storms over the next hour or two. Farther south, a recent attempt at deep convection near the center of the low over Crane, Midland, and Upton Counties in TX failed, but additional attempts are expected in this area as surface convergence persists and large-scale forcing for ascent gradually increases. Steep mid-level lapse rates and robust deep-layer vertical shear across this region would support strong updrafts capable of large to very large hail with any sustained development. Primary uncertainty is whether or not updrafts can be sustained amid the substantial low/mid-level dry air in place. Given the conditional risk for large to very large hail and potential need for a watch, observational data and convective trends will be monitored closely over the next couple of hours for signs that deeper convection can be maintained. ..Mosier/Smith.. 04/09/2024 ...Please see www.spc.noaa.gov for graphic product...
