Hoosier Posted June 30, 2014 Share Posted June 30, 2014 The new severe thunderstorm watch "only" mentions winds of 80 mph. Was hoping for more from a PDS severe. Link to comment Share on other sites More sharing options...
SouthernNJ Posted June 30, 2014 Share Posted June 30, 2014 There was a solid couplet about 4 miles SE of Tipton at 3:28 PM CDT, but with the speed of line, it will be difficult to warn such signatures unless it persists for a few scans. Link to comment Share on other sites More sharing options...
cyclone77 Posted June 30, 2014 Share Posted June 30, 2014 Nice couplet near Onslow, IA as well. That couplet is passing almost on top of where the one from last night passed west of Fulton IA. Link to comment Share on other sites More sharing options...
