Does this seem like a radar glitch to you?
« on: November 25, 2006, 09:31:20 AM »
This radar image shows a very strong echo this morning:

But the same image from Cincinnati does not show anything:

I'm not up there, but I don't think its raining:

I had not seen a false echo stay so long and be so large - wierd.  Has anyone else seen ghost echos like this before?

It's probably too late, but do you know what the NEXRADs straight from the NWS looked like at the time?

The NOAA doppler takes a series of slices of the sky every time it updates. I'd be interested to see the other slices to see if the anomoly is just on one slice.

But the one thing which makes me think it's a glitch is that the radar updates every 4-10 minutes... and these images are 1 minute apart.

Well I think that carterlake was correct - it was an Anomalous Propagation.  It did show up on our local TV station's radar as well.  It lasted about 30-40 minutes.  You can even see it show up 15 minutes after my local screen caps on the national radar loop at 9:30am (below).  I've never quite seen something like that so definded and not ground clutter.
