Yes, I see that. Judging from the hole around the LWX radar, I suspect it's all (or mostly all) aloft. You can even some of the heavier returns southwest of the radar site, especially in the early part of this loop, suggesting the heavier virga likely extends over the radar site but the beam is too low in those areas to detect it. With that said, the hole does look to be shrinking, which would suggest some of the snowflakes are making it further down into the atmosphere. But this is only like 10, maybe 15, dbz returns.
