Weather Postin’ retrieves the current weather provided from <a href="http://www.rssweather.com/" title="Source of weather information" rel="nofollow ugc">RSS Weather</a> when your post is published. After that, when you view your posts the weather conditions will display at the end of your post. This does not alter the original text of the post; it is only displayed at run-time.
Please note, that posts prior to activation will not have weather associated with them. Yes, obvious, but worth saying. :o)

Weather Postin'

Saves current weather information when a post is published.  Weather information is then displayed after the post's contents.

A simple weather plugin Cherkasy Weather
This plugin shows the weather in Cherkasy using the API from Yahoo.
Use the built in widget or add it somewhere else with this shortcode:

<h3>Arbitrary section</h3>
You may provide arbitrary sections, in the same format as the ones above. This may be of use for extremely complicated 
plugins where more information needs to be conveyed that doesn’t fit into the categories of “description” or 
“installation.” Arbitrary sections will be shown below the built-in sections outlined above.
