I've got the same problem a time ago, i can't find documentation for
LANDUSE.TBL, but may i can help you a bit:
You must edit LANDUSE.TBL provided with WRF, the secion you must modify is
USGS for summer and winter.
The fields are:
SCFX=factor for albedo modification with snow
SFHC=i've no idea, but it's not used
in this case you don't need to change the variable MMINLU
You has edited GEOGRID.TBL?
i hope these can help you
