This appeared to be a transient issue from NOAA data causing downstream processing errors. The problem is no longer apparent.
AS may have a corrupt data set loaded if you had this issue. If you get an error on startup, please attempt a restart, and if the issue persists please try and uninstall/reinstall cycle or you can shut down AS and manually remove all the items in your C:\users\username\HiFi\[product name]\Weather folder and a new weather set will be created. If you need assistance please open a support ticket. Thank you.
