A watch is not expected. DISCUSSION...Scattered convection has developed along the Gulf breeze front within a very moist (low 70s F dewpoints), high PWAT (2-2.5 in.) airmass. 12Z/18Z observed soundings from the region showed poor mid-level lapse rates. This, and very weak shear, will keep storms unorganized. However, water-loaded downdrafts may produce locally damaging winds with low-level lapse having steepened substantially this afternoon. ..Wendt/Guyer.. 08/18/2026 ...Please see www.spc.noaa.gov for graphic product...
