Unclear abbreviations, like "Tsra"

I just set up a Drupal site with your weather module 4.4.0, and it's very cool. :) The only problem is that the weather service you use put the word "Tsra" in my weather box, and when my father saw the site, he had no idea what that meant. Nor did I!

I googled (http://www.google.com/search?q=TSRA+thunderstorm+OR+thunderstorms) and found pages like:

* http://nappf.com/nappf_metar_taf.htm says "TS" means "Thunderstorm" and "RA" means "light to moderate rain"

* http://www.srh.weather.gov/jetstream/append/acronyms_t.htm explains many such abbreviations, spelling each one out.

It would help a great deal if you could turn the abbreviations into their more meaningful equivalents!

Thanks,
