DISCUSSION...GPS PW values near Del Rio have substantially increased from near 1 inch at 00 UTC to above 1.5 inches as of 10 UTC, with surface dewpoints increasing through the low 70s F. A storm has recently developed northwest of Del Rio across eastern Terrell County, and this increase in deeper low-level moisture beneath relatively steep midlevel lapse rates may yield additional storm development near a weak surface front draped across the TX Hill Country vicinity. MUCAPE of 2000 J/kg, strong (60+ kt) deep-layer shear, and elongated hodographs are conditionally supportive of supercells capable of producing large to very large hail, if deep convection can mature within this regime. In the absence of substantial large-scale ascent, storm coverage through the morning is uncertain. However, given the favorable environment, watch issuance is possible if short-term trends support development of persistent intense storms. ..Dean/Mosier.. 05/06/2026 ...Please see www.spc.noaa.gov for graphic product...
