Hi there.
Two doubts:
1) is possible make a tweet about if it's raining and what kind?
2) Within the tweet summary of the day of the principals variables, if it rained appear the amount dropped?
examp:
If not rained:
tweet: "08:00 maxtemp: 30º; mintemp: 15º; Max UV: 10; maxhum: 80.
If rained:
tweet: "08:00 maxtemp: 30º; mintemp: 15º; Max UV: 10; maxhum: 80. today rained 12mm"
