Hi Bart,

Try changing your namelist from this:
>  start_year                          = 2009, 2000, 2000,
>  start_month                         = 12,   01,   01,
>  start_day                           = 20,   24,   24,
>  start_hour                          = 00,   12,   12,
>  start_minute                        = 00,   00,   00,
>  start_second                        = 00,   00,   00,
>  end_year                            = 2009, 2000, 2000,
>  end_month                           = 12,   01,   01,
>  end_day                             = 20,   25,   25,
>  end_hour                            = 00,   12,   12,
>  end_minute                          = 05,   00,   00,
>  end_second                          = 00,   00,   00,

To this:
>  start_year                          = 2009, 2000, 2000,
>  start_month                         = 12,   01,   01,

>  start_minute                        = 05,   00,   00,
>  start_second                        = 00,   00,   00,
>  end_year                            = 2009, 2000, 2000,
>  end_month                           = 12,   01,   01,
>  end_day                             = 20,   25,   25,

The restart file is generated after 5 minutes given your namelist.  If this is the case, the start/end dates needs to match your restart file.

Hey Jeremy,

the original model run was 24h.

> Since it wasn't the start and end date giving you problems, the other likely culprit would be that the restart file itself was generated from a time period outside of the start and end date that you've listed in the namelist.  The way I understand the restart variable is that it generates a wrfrst file at the end of each interval specified in the namelist.  That is, your restart interval is 18000 seconds, meaning that after 5 minutes from your start time, a restart file is generated.  As your namelist sits now, you're trying to use a restart file that has no data for the 5 minute period you're trying to model, but has data for the next 5 minute period (assuming that the wrfrst file came from another run with the same start and end date).
