There were two areas in consideration today: eastern Carolinas and the high plains from KS to eastern NM. A boundary aligned NW – SE set up from northern OK to near GCK and intersected another boundary going toward LaJunta, CO. The intersection point near GCK initiated a storm. Other storms formed near Springfield, CO and in Woods county, OK. The Woods county storm is starting to look supercellular with a TBSS. The convection in the Carolinas is composed of ordinary cells.

We figure on starting operations for Northern OK and SW KS given the NW-SE boundary intersecting a developing low level jet may keep active convection going for a longer period of time than the departing convection in the Carolinas. There’s also a good possibility that the PAR area may be involved and so the warning forecasters would have an easier time transitioning from gridded warnings to PAR activities.
