Scattered points not plotting on top of pcolorm?

I want to make a plot of wind speeds as a colormap and then plot points on top of the colormap that shows the trajectory of a satellite over the region. However, once I plot the points, only the color maps show up. How do I plot the points so they can be seen?

lat1=d.lat(1); lat2=d.lat(20); lon1=d.lon(1); lon2=d.lon(40);

figure(400)

subplot(2,2,1)

worldmap([lat1 lat2], [lon1 lon2])

pcolorm(d.lat,d.lon,ccmp.wind1(:,:,19))

h=colorbar;

caxis([0 25])

ylabel(h,'CCMP Wind Speeds')

title('CCMP Winds at 12 AM on 1-Mar-2012');

subplot(2,2,2)

worldmap([lat1 lat2], [lon1 lon2])

pcolorm(d.lat,d.lon,ccmp.wind1(:,:,20));

hold on

plotm(m2.lat,m2.lon,rand2,'k*','LineWidth',15);

h=colorbar;

caxis([0 25])

ylabel(h,'CCMP Wind Speeds')

title('CCMP Winds at 12 AM on 2-Mar-2012');

subplot(2,2,3)

worldmap([lat1 lat2], [lon1 lon2])

pcolorm(d.lat,d.lon,ccmp.wind1(:,:,21))

h=colorbar;

caxis([0 25])

ylabel(h,'CCMP Wind Speeds')

title('CCMP Winds at 12 AM on 3-Mar-2012');

subplot(2,2,4)

worldmap([lat1 lat2], [lon1 lon2])

pcolorm(d.lat,d.lon,ccmp.wind1(:,:,22));

hold on

plotm(m4.lat,m4.lon,rand4,'k*','LineWidth',15);

h=colorbar;

caxis([0 25])

ylabel(h,'CCMP Wind Speeds')

title('CCMP Winds at 12 AM on 4-Mar-2012');

The resulting plot looks like this without any of the points:

How do I fix it?

It's difficult to diagnose the problem without seeing what your data values are. My first guess would be that the z-data for your satellite trajectory (i.e. rand1/2/3/4) are negative. By default, pcolorm places its surfaces at z = 0, so the plotted lines might be hiding underneath those surfaces.
