updated the text

Changed the text regarding the precipitation to be a little more human
readablle. I added a condition that displays one of two emails. The
first condition is if precipProb = 0, The message just displays ‘no
rain forecasted for today’ in the rain portion of the email. The 2nd
case is when precipProb != 0, the code first assigns a ‘category’ to
the daily summation of rainfall and rather than printing out some value
of inches (Which most people can’t quantify themselves) it will print
out a short blurb about the amount of text.
