I live in a country where even in the winter time there can be many days without rain, and some of them can be pretty hot, too. In such days I often leave the windows open in the morning.

However, from time to time I forget to check the weather, and end up leaving for work with the windows open, even though it's going to rain.

No more! I recently configured IFTTT to add a task reminding me to close the windows before I leave if it's going to rain tomorrow. Here's how you do that:

1. define a ifttt rule for sending an email if it rains tomorrow (through http://ifttt.com/recipes/12507, for instance)
2. configure the weather settings for your location
3. change the email recipient to your RTM import email
4. change the subject to your desired list (inbox for instance)
5. change the mail body to "close windows 21:00" or something like that (depends on when and how exactly you'd like to be reminded, the syntax is similar to the quick add feature)
6. You're done!
