[wxqc] Spike in quality report?

[Terry Kester (comcast)]

Well, I may as well join in.  I'm in Taylor MI and had the same spike.  And
I send the same data to wunderground and they didn't get the spike so me
thinks something went a little haywire with CWOP QC.

I have seen this too Jim, on my qc reports. I believe the last time I saw
it, I looked back at the weather data link and saw that one of the
reportings was way high (I believe it was barometer)... don't know though
whether that was actually sent by the WXTrak device, or the packet was
decoded wrong by a receiving station.

I'm just wondering if anyone has seen this happen before and knows what
might have caused it.

Just prior to 1000Z it shows an extreme spike that doesn't show up in my
logs. The same thing happened to AR825 which is the closest station to me. 

None of the other close stations seemed to have the same thing happen. Also
wondering whether a spike like this affects our averages or if the system
recognizes it as an anomaly and "throws it out".
