Not many lightning strikes going on so far today. Lightning probablility is showing strikes that are occuring. The difference between scale0 and scale1 seems to support the idea that scale 0 might give more specific information over scale one on which storms have the best lightning probabilty. Scale one might be useful for overall early coverage and scale 0 might be a better indicator as more storms develop.
