We’re starting the Live Blog about one hour after the IOP occurred. An isolated supercell developed just west of Norman, and began to track NE. Two more supercells developed north of this storm, near Guthrie and Stillwater. We’re doing a PAR IOP at the moment, as the storms are outside of the CASA network, but we are keeping our eyes open for any additional development to the SW of here. So, for now, Dave B. and Mike C. are working with Pam H. and Les L. on the PAR station. Mike Magsig, our guest evaluator, has decided to do a solo gridded warning exercise on the Oklahoma City supercell. Unfortunately, we discovered a fatal bug in our warning software which forced us to create a build that was slightly old, and which brought back a few of our recently fix bugs.
