Update 2:55 PM
Here's a version of the figure above with some annotations.
This is a vertical scan (a.k.a. RHI) of radar reflectivity taken toward the Broads Fork Twin from SR-111 near Baccus. The sloping area of high reflectivity near the right hand side of the image is the west slope of the Broads Fork Twin. The radar returns are deeper and stronger over and upwind of this slope. At issue is whether or not this is due to mountain effects on the storm or if we have just coincidentally cut through a precipitation band when it is over and upwind of the western slope.
