This code

  • is inspired by this article on "small data"
  • checks the following webpages for information regarding the "Grosswetterlage" in central / NE europe:
  • save the individual images if you want
  • create an overview map containing all the relevant images;
    • left column: analysis (current time)
    • right column: prediction (future)
    • these overview maps can be stored
    • these stored files are interesting to analyze in their sequence over time (compared with the predictions)
  • this might be useful for preparing skiing or sailing trips, or just general curiosity


  • done 20130517 plot the text of the prognosis in reasonable way (bottom left)
  • make the headings prettier
    • date and hour formatting
    • left: analysis; right: prognosis (only KMNI)
  • find out when a png is flipped and when it is ok
