DISCUSSION...A cluster of strong to occasionally severe thunderstorms has developed amid warm-air advection, within the warm sector, ahead of a weak cold front. Environment throughout this warm sector is characterized by stable low levels, but steep mid-level lapse rates and modest mid-level moisture supporting elevated storms. Forecast soundings suggest these storms are likely based between 850 and 700 mb. Mesoanalysis estimates MUCAPE is around 2500-3000 J/kg, with effective shear near 40 kt. These environmental conditions support organized updrafts capable of hail, and a few supercells have already developed across the region.=20 Dry low to mid-levels will likely impact storm longevity as they move east of the primary warm-air advection zone. These conditions favor a more outflow-dominant storm structure with eastern extent. Despite low-level stability, there is still some chance for a few stronger surface gusts, particularly if cold pools within the cluster can amalgamate. Any gusts will likely remain below severe thresholds. ...Mosier/Edwards.. 07/27/2023 ....Please see https://urldefense.com/v3/__http://www.spc.noaa.gov__;!!DZ3fj= g!6y1NpJfsOuO1DKlOeOhLjOwMZxWpHcNhCyh_Cq5aOxcsbDBy_kf2nII7RIp_HRAqmgzHOHchK= zzUuzpMD8hb4qmJh7M$ for graphic product...
