086 ACUS11 KWNS 251958 SWOMCD SPC MCD 251957 KYZ000-OHZ000-INZ000-252130- Mesoscale Discussion 1411 NWS Storm Prediction Center Norman OK 0257 PM CDT Tue Jun 25 2024 Areas affected...southern Indiana...far southwest Ohio...and northern Kentucky Concerning...Severe potential...Watch possible Valid 251957Z - 252130Z Probability of Watch Issuance...40 percent SUMMARY...A cluster of storms across western Indiana may produce some damaging wind gusts across eastern Indiana, northern Kentucky, and far southwest Ohio this evening. DISCUSSION...The airmass ahead of a storm cluster in western Indiana continues to destabilize with SPC mesoanalysis suggesting an uncapped warm sector. As long as the airmass ahead of this cluster continues to destabilize, at least some damaging wind threat is expected to persist. Therefore, a severe thunderstorm watch may be needed across southeast Indiana, northern Kentucky, and southwest Ohio. However, uncertainties remain. The outflow boundary from the morning continues to move south and it is possible this will undercut the storms which could weaken them. Visible satellite and the KIND WSR-88D also show a showing trend of this outflow boundary slowing over the past hour. Therefore, this boundary may provide the focused corridor for the threat. Additionally, some storms have developed along this boundary in southeast Indiana. This is east of the greatest instability and thus, these storms will likely remain below severe limits. Trends of upstream convection and development along the outflow boundary will be monitored for a potential downstream watch. ..Bentley/Hart.. 06/25/2024 ...Please see www.spc.noaa.gov for graphic product...
