Jim, Have you seen what Spokane NWS is doing
http://www.wrh.noaa.gov/Spokane/index.shtml Click Current Weather. I think Missoula NWS may have started this. I like that there are many stations other than airports shown. If you're a C programmer, take a look at Observation Monitor at

Missoula used to have a web page where you could watch it would show only stations that met a certain weather criteria, such as stations where wind speed exceeded XX or those where dewpoints dropped by more than Y over a certain period. In another words, it was like an 'alerter' tool. Dennis Everett WA
