For those who want to use NOAA for their weather forecasts, I wish I had a nice and completed solution but I got stuck and abandoned it. But someone can pick it back up and also get the forecast and current conditions in addition to the alerts as described above. All the work I have done so far is documented at:
I got stuck trying to process out the forecasted precipitation as it is presented in a list of elements and you don’t know ahead of time how many elements will be in the list and what time period each element covers so it was hard to calculate the full day’s forecast.
It’d be easier to handle in Python than Rules DSL so it might be worth someone having another go at it if interested.
