Check out my post above...the one you're referring to is some banding...I think there are gravity waves in there as well. You can see it pushing into Eastern LO and enhancing the precip.
Thinking there are gravity waves pulsing from E to W...can see one here (focus on radar ground zero):

Would be nice to see the name-calling/labeling ended in the climate change section...this isn't Junior High... weenie, denier, alarmist, etc. gets old very quickly. Don't you all agree?
