Help with updating text on weather website.

Hello! I’m completely new to web design, but was trying to put together a simple weather website that updates with current conditions when the user goes to the site. My site is http://jasontdunn.wixsite.com/jsos/roanoke I’d ultimately like the parameters (temp, dewpoint, etc.) to update automatically with the latest data when the user goes to the site.

The data comes from a set of weather stations, which produce a CSV file with the latest information. My question is, what is the best way to get the data to update on the page with the latest information? Is there a way to fetch the data from the CSV and update the page or update the database? Thanks for any help!
