For those who are running WeatherLink, there's a new Weather Underground
module available from their web site that will hopefully cure the occasional
hangup problems.  Part of the documentation follows:

Changes through 1.7:
+ fixed wind direction values for uploading archived observations
+ added 10 second timeout to observation uploads in case WUnderground is
unreachable
