I also noticed that the Weather Stories were no longer displaying a few days ago. I was preoccupied with other script issues until this evening when I decided to have a look at the script.
Voila! A simple fix appears to work. Find in DATA SETTINGS in wxStory_inc.php
$useCURL = true; // true=get data by cURL method false=stream data
and change this switch to
$useCURL = false; // true=get data by cURL method false=stream data
This
worked for me with any WFO I tested, and I hope it will work for you, too.
