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".
