Presumably one bad pressure reading at 08:09. Data corruption is unusual with Oregon stations, as the data has a checksum, but the checksum is a simple addition of the bytes (modulo 256), so if the corrupted data happens to sum to the same value it will be treated as valid. The alternative is that the data wasn't corrupted, the sensor actually generated that reading.
