The WordPress RSS widget update itself  twice a day. To make that more frequent you can add this bit of code to your functions.php file.

add_filter( 'wp_feed_cache_transient_lifetime', create_function( '$a', 'return 1800;') );

The value 1800 means the number of seconds before the RSS widget updates itself. 1800 seconds is 30 minutes. You can just copy and paste this code at the bottom of your functions.php file.
