ESP8266 , Arduino ide , PWS posting to WUnderground

Hi All, I would like to say THANKYOU !! to anyone that can help with this project I'm working on, I'm new to this especially the ESP8266 01. This is programmed with the Arduino ide not at commands.
I'm not so familiar with this client.print , etc

I have a PWS sending a string preformatted like this :
(&dateutc=now&winddir=270&windspeedmph=7.0humidity=45.4&tempf=43.1&rtfreq=10&action=update)

Its remotely sending via an XBEE to another XBEE (serial) output to an esp8266 via TX RX. The esp8266 then sends wifi to the router and updates WU.

The problem is I'm not sure how to post to the ,rupdate.weatherunderground , and the incoming serial string from the esp8266 at once.
I can only find info on creating a string and posting. I can connect to the router just not sure how you post as I'm not familiar with web site posting.
I need to post one line to WU like this below.. (the first part I can do, the second part in red is what the esp8266 has coming in via serial so I need to join then and post.

This is way late, but here is an email I received when trying to set my own station up.

Hi!

This is great news! Yes, there is a way to upload your data to Weather Underground from loggernet I believe. If your stations are not connected to loggernet, then you may want to write a script yourself to upload to Weather Underground.

The Upload Protocol is here:

Thanks and let me know if you have any other questions,
