While I was in NW IA on Sunday…

While I was up in NW IA with a dozen other chasers, severe weather almost hit home. The NWS confirmed today that 2 tornado’s touched down, from just NE of Pella, IA; ending near Malcom, IA. For many people that know me, I grew up and graduated from Lynnville-Sully Schools, so this kinda hit home per say.
