You only got one point because you did not specify your Row Dimensions. This is very important when you import to a table or a feature class it will determine how many feature you get. The Row Dimension should be your lat, lon or your south_north, west_east dimensions.
Here is what the command should look like
gp.MakeNetCDFTableView_md(wrfout_jme_nc, "WTHRSH_MTHD1;WTHRSH_MTHD2;XLAT;XLONG", FLAGnc, "south_north;west_east", time_value, "BY_VALUE")
