Hi In the feed entries the 'geometry' is given as sets of UGC or FIPS6 boundary names, for each weather warning. You could read the XML with Requests, extract the records, generate geometry by (say) a Query on a feature service in ArcGIS Online or a local copy of the boundaries, then do a local overlay with your shapefile. This is quite a mission for someone new to Python. An alternative, if you have money to throw at this (licensing an extension), is creating a custom data format using the Data Interoperability extension - no coding but some configuration, based on reading RSS.
