David,

presumably you are seeing the radar mosaic at this time,
albiet it looks like you are running 1 hour behind in the NEXRAD and
FNEXRAD feeds you are getting from frost.wunderground.com.
The Conduit feed looks good.

I checked the other sites getting FNEXRAD via frost.wunderground.com
(eg U. Oklahoma), and the same problem exists...and they aren't getting
Conduit. So, it may be that the NEXRAD|FNEXRAD feed out of wunderground.com
is slowing things down.

I'll pass this on to Jeff Weber and see what he thinks about the
NEXRAD topology.
