Trends are being monitored for possible watch issuance. DISCUSSION...Isolated thunderstorms are ongoing along an outflow boundary approaching the Middle Texas Coast vicinity. Visible satellite shows towering cumulus developing westward along the boundary across south-central TX. A similar environment to that across southeast TX where widespread severe is ongoing is present across this area as well. A hot (mid/upper 90s) and very moist (70s F dewpoints) boundary-layer is contributing to strong instability (2000-3500 J/kg MLCAPE). A pocket of steep low-level lapse rates is also present in latest SPC Mesoanalysis data. Initial thunderstorm activity has struggled to intensify and it is unclear if additional storms will develop. If more storms develop and clustering occurs, damaging wind potential will exist. Trends will be monitored for possible watch issuance. ..Leitman/Hart.. 05/28/2024 ...Please see www.spc.noaa.gov for graphic product... ATTN...WFO...HGX...CRP...EWX...
