No, and I get the confusion, but those are not necessarily the exact temps. I believe the raw data is in Celsius and they round off the number and then convert to Fahrenheit, which can lead to discrepancies. I reached out to the NWS one time about this and they confirmed. In fact, you can see a number of examples on the link below where the 6-hour or 24-hour highs/lows don't align with the 5-minute readings.
