Continuously pulling variables off a website to use on Matlab?

I am trying to continuously pull variables off this website (or a similar website)

http://ift.tt/2n4gAnb

and use the variables in a Matlab code for some calculations. The variables i need are in the picture below.

I realize i could download a .txt from another site with the info but I need to update the variables every 10 secs or so, so that's not going to work.

I would really appreciate any help in terms of where I can find resources to do this or something that will get me started. thank you!
