[Expect] has a "weather" command supplied as an example in its source
distribution.  "However, note that the version in Expect needs a modification to handle
a new web site location for the weather information, and that new site
requires the machine doing the request be located in reverse dns lookup or
it refuses to provide data." [[June 2002, [LV] ]]

"[A little rain forecaster]",
[Jason Tang]'s [tclweather] applet,
[Iain B. Findleton]'s collection of weather-related [Tcl fltk] demonstrations,
and ...
are all interesting.



Several of the documented [TclSOAP]
examples focus on weather data.
