Cloud base weirdness

I have just upgraded to the latest version of CMX, upon running it again, the cloud base value spiked to 5295 ft before going back to normal. I closed CMX and reopened it to see if it was a one off, but it did the same thing with the same value.
No biggie, just thought it was weird..

Are your temperature and dew point values okay around start-up? The figure 5295 suggests a temperature/dew point difference of about 13.2. Your current air temperature is close to 13.2. Just an observation

No iffy values from temp/humidity/dew point.
I saw the value appear in the real time data, which was also logged to SQL.

Looks like it may be using the dewpoint value before it is initialised from the first data at start-up and thus zero.
Which station type are you using, still on the WLL? (I'll check that one first)

Yep - still on the trusty WLL

Found the issue, it applies to a few stations - I'll have to split up a mega temperature function and move all the bits associated with dewpoint out to their own code. All the stations will need changing to accommodate that, but it should be done - I see some beta testing for the next release!
