Utah MAPS - Utah Climate Center (usu.edu)
1. find a station (you can enter a town and a map will show you the stations on record)
2. customize your report (make sure to select English, unless you want the metric conversion)
3. download an Excel file (they will ask for an email, but reports are generated quickly.)
