First of all, I briefly introduce myself. My name is Luis Vilches and am the ambassador of the OKI in Colombia.
I have checked the provided URL for this topic (Weather Forecast) and I would like to comment some issues about associated data. The data are associated with Colombian's municipalities and cities. Thus, for instance, I can recover data for Bogota. However, data are provided for only one location, due to the fact that they are associated with only one latitude and longitude. It can be checked in the following screenshot.
On the other hand, with respect to different meteorological variables, which are listed in http://global.survey.okfn.org/entry/co/weather, provided data (http://www.pronosticosyalertas.gov.co/datos-de-pronostico) do not present "Temperature extremes" and values of "Wind direction" are very strange. Besides, "Probabilidad de tormenta" and "Pronóstico" do not match.
Furthermore, there is another URL related to this topic in the Colombia's Open Data Portal "Pronóstico de tiempo y alertas hidrometeorológicas"
However, this URL do not provide data, just a WSDL file.
Finally, although this topic is related to Weather Forecast, I would like to highlight that it is not possible to collect historical data associated with this topic.
