 </code>
+===== Talking to WeatherBot =====
+WeatherBot (e.g. [[https://hub.polari.us/weather]]) can now take various request forms. Sending these:
+<code>
+New York,NY,US
+or
+Stockholm,SE
+</code>
+results in the original behavior - you get the current conditions.
+Sending any of these:
+<code>
+Current conditions in Jefferson City,MO,US
+Currently Uppsala,SE
+Current in London,UK
+Conditions for Moscow,RU
+etc.
+</code>
+also results in the current conditions.
+But sending any of these:
+<code>
+Forecast for London,UK
+Forecast in Dallas,TX,US
+</code>
+will return a table of forecast data for the city in question, going out 3 days. This is just a first attempt to do simple request processing based on language, and, yes, it's only in English for now. But now you can at least get a forecast!
