I know the maximum temperature reached in a netcdf file I'm working with is 314 K. However, when I plot it using countourf, neither that temperature nor anything close to it is visible in the plot. And the colorbar color assigned to this max temp does not match what I'm seeing in the plot. Here is the code I'm using:

ncfile1='./ANN_climo.nc';
var1='TS';
tmp1=squeeze(ncread(ncfile1,var1));
lat=ncread(ncfile1,'lat');
lev=ncread(ncfile1,'lev');
lon=ncread(ncfile1,'lon');
%checking max/min temps
max(max(tmp1))
min(min(tmp1))
%plotting
tmp2 = transpose(tmp1);
contourf(lon,lat,tmp2, 'LineStyle','none');
hold on
%adding dotted line for freezing point
contourf(lon,lat,tmp2, [273.0,273.0], 'linestyle', 'none');
contourf(lon,lat,tmp2,[273.0,273.0],  'linestyle', '--', 'linecolor', 'k')
%specifying the colormap
colormap('turbo')
%check default colorbar limits
caxis
set(gca,'fontsize',14);
ylabel('Latitude (\circ)')
xlabel('Longitude (\circ)')
h = colorbar;
xlabel(h,'(K)');
hold off
