map projections

All-
I am trying to plot the Unified precipitation dataset from CDC. It is a
netcdf file but has no information on the map projection. The data is on a
lat lon grid:
netcdf precip.1993 {
dimensions:
         lon = 321 ;
         lat = 161 ;
         time = UNLIMITED ; // (365 currently)
variables:
         float lat(lat) ;
                 lat:units = "degrees_north" ;
                 lat:long_name = "Latitude" ;
                 lat:actual_range = 20.f, 60.f ;
         float lon(lon) ;
                 lon:units = "degrees_east" ;
                 lon:long_name = "Longitude" ;
                 lon:actual_range = 220.f, 300.f ;
         double time(time) ;
                 time:units = "hours since 1700-1-1 00:00:0.0" ;
                 time:long_name = "Time" ;
                 time:actual_range = 2568384., 2577120. ;
                 time:delta_t = "0000-00-01 00:00:00" ;
                 time:avg_period = "0000-00-01 00:00:00" ;
         short precip(time, lat, lon) ;
                 precip:long_name = "Daily Accumulated Precipitation" ;

When I attempt to plot it using the
mpProjection = "LambertConformal"
mpLimitMode = "Corners"
mpLeftCornerLatF = lat(0)
mpLeftCornerLonF = lon(0)
mpRightCornerLatF = lat(160)
mpRightCornerLonF = lon(320)

The image that is produced has the map background rotated 90 degrees but
the displayed data is in the correct orientation.

I do have this:
  tfDoNDCOverlay = True

I have no idea if this is a Lambert grid but other projection types didnt
seem to work either.

Any ideas?
