Creating a script that can extrapolate temperature values from a site and paste them into a text sheet or Numbers file

Good morning, I am writing to you because I need someone who would be able to create an Apple script that is able to extrapolate temperature values from a website and can paste them into a text sheet or a NOAA file. I generally take all the temperature values from other sites and I write them manually, but unfortunately this site in question does not directly provide the minimum and maximum temperature values, but only the temperature values updated every half hour and the presence of a summary graph. So I don't know for sure the values actually recorded. The site in question is the link http://himet.it/gmaps/stazioni/idrografico.html and here is how the temperatures look (which are updated every half hour), and the graph:

The stations for which I would like to have the temperatures written on a file through through the script are (look at the arrows):

14 locations. I hope it can be done because it is vitally important. thank you.
