Bill and Brian have been encouraged by Greg to check out the small azimuthal velocity couplet south of KDDC. There are several waves rolling up along the gust front. They’re considering a low probability tornado swath all along the line and including the bow. Wait, they’re actually dong it! This could be the biggest swath created in this experiment to date. They’ll consider a 20% probability. Brian entered 270deg at 35 kts and a high uncertainty since the line is just forming up.
