What are the potential downsides or challenges associated with providing significantly longer tornado warning lead times than currently typical?

WoFS is a high-resolution computer model predicting severe weather probability and location. Its success in Carter County demonstrates its potential to significantly increase tornado warning lead times, potentially saving lives by providing ample time for evacuation and shelter. However, studies suggest that excessively long lead times (beyond 30-34 minutes) might reduce the sense of urgency.
