The final day of forecast activities for week 4 didn’t see much change geographically, with groups operating in the Boulder, Goodland, and Hastings CWA’s. The Goodland group would later move to Dodge City as activity to the south looked a little more promising. Once again, the Boulder group found the PGLM total lightning Flash Extent Density and Lightning Jump information to be quite valuable in monitoring fluctuations in storm/updraft intensity. One particularly strong storm near Simla, CO produced a tornado from which we were able to view live streaming footage (see image below). Activity in the other CWA’s, was a little slow to develop, giving participants ample time to evaluate the pre-convective products.
