Spikes in graphs but not in data

Hi, please see the graph from my station for yesterday: http://www.wunderground.com/personal-...

Around the period 03:02 to 04:00 UTC the data is mangled. It is also shown with one data point per minute instead of the usual 5 minutes.

My station reports every 48 seconds. I went back through my logs to see what was sent in the URL to wunderground for the period 03:10 to 03:20 UTC and the temperature looks fine. It doesn't have spikes like the graph.

This seems to be happening every day around the same time.

Can you please let me know what is happening and what I can do about it? Here is the temperature reported by my station for that period. I can also give you the complete HTTP GET requests used:

03:10:47 - 49.46F
03:11:35 - 49.46F
03:12:23 - 49.46F
03:13:11 - 49.46F
03:13:59 - 49.46F
03:14:47 - 49.46F
03:15:35 - 49.28F
03:16:23 - 49.28F
03:17:11 - 49.28F
03:17:59 - 49.28F
03:18:47 - 49.28F
03:19:35 - 49.28F
03:20:23 - 49.28F

Here is an example HTTP GET:


Thanks, Andy

Please direct your question to support@wunderground.com, this is a forum for API users

No response, not even a "we've got your email", nothing. I guess Wunderground doesn't actually care about PWS issues? No support area for PWS users? How lame... :(

BTW I am using a Wunderground API - the one for PWS to report data.

I'm sorry about that! Sometimes we get overwhelmed with support emails.

It looks like we replied back on the 25th. If you didn't receive it, please write to us again -- I'll keep an eye on it.

Yes, I got the email and sent a reply on the morning of the 26th. Heard nothing since then.... Do you have a direct email address WunderWilliam?
