Changes based on suggestions

You were so positive about my changes that I went a little deeper.
I couldn't change to the suggested "raining fucking heavily" because then I would have to change almost every line, and some of the humor comes from the contrast of detaching the adjective from the noun. I like the fact that it sounds kind of computer-generated by following a few rules, but really, it's just strings.
Changed "clear outside" to "awesome outside" 
I was thinking of changing "moderately" to "kind of" or "kinda" but that would change the computery nature of it.
I also figured out 950-962 are the Beaufort scale and adjusted accordingly http://www.spc.noaa.gov/faq/tornado/beaufort.html
