Western OK…IOP begins 5 PM

Forecasters completed PAR and CASA Training, and are now learning WDSSII using live data of a supercell near Altus, OK. There is a second severe storm near Elk City. Both storms are moving very slowly…seemingly balanced by southeasterly low level inflow and southwesterly mid level steering flow. They may also tend to propagate into the instability axis…which is unfortunately just west of the CASA network. With some luck, however, we could see storms reach the western parts of CASA later this evening. PAR operations will begin at 5 pm.
