Sample of weather block
Weather of related places of contents you read is displayed in the left-side bar.
It's not for all contents, but if the content has location attribute, the weather of the location is captured and displayed.
Actual data is gotten from http://weather.noaa.gov/ Because the data issued from airports, it's not names of cities, but names and locations of the airports displayed.
In a database I use, for example, "Arturo Merino Benítez International Airport" of Santiago, Chile shows "Pudahuel" as its location. In this case, I changed "Pudahuel" to "Santiago".
