While chasing this afternoon and evening my son and I chanced upon this scene looking northeast from the Chancellorsville area (map above):
This was the last in a series of 3 photos I hurriedly snapped at 8:11 pm. I called in a wall cloud and funnel report to the NWS Sterling office, along with a mention of a possible tornado. No warning was issued for this storm…not sure why. We had already seen another funnel as we headed east through the Wilderness Rte 3/Rte 20 interchange, so this wasn’t a freak occurrence. In fact the parent wall cloud grew to significant size before disappearing behind a developing rain shaft:
This appears to be another example of rotation on a storm forming below the normal radar horizon for the Sterling radar. We certainly didn’t dream this one up!
