an issue with bs4 scraping

[komarek]

i have this script running on my raspberry that is scraping weather report from an url:
http://it.freemeteo.com/tempo/
this is the snippet of the weather prevision html:

<div class="pred"><script type="text/javascript">
          document.write(Icons.GetDescription(1,'CurrentWeather'));
        </script>SUNNY DAY</div>

i'm using bs4
 i do something like this: 

r = requests.get(urlWeather)
soup = BeautifulSoup(r.content, 'html.parser')
soup.body.find('div', class_="pred")

but the result is
<div class="pred"><script type="text/javascript">
          document.write(Icons.GetDescription(1,'CurrentWeather'));
        </script></div>

the Weather part vanishes
it is probably a problem of the javascript
anyone knows the solution?
cheers
