    YYYY-mm-dd_hh:nn is Year, Month, Day, Hour, and Minute (USGS Timeslice files only)
    CC is the model cycle runtime (i.e. 00, 06, 12, 18)
    MM is the forecast lookback period (i.e. 00, 01, 02)
    FFF is the forecast hour (i.e. 000, 006, 012, 018, etc)
    MEM is the long range forecast member (i.e. 1, 2, 3, 4)
