Problem contouring data

I'm hoping someone can help me out as I'm having problems getting
contours/colors to show up on my map when I specify:
res_at_cnLevelSelectionMode = "ManualLevels".

When I plot the area I'm interested in with res_at_cnLevelSelectionMode
= "AutomaticLevels" I get the following:

Which does show a range of temperature changes from about 2.48 to
2.96 degrees F.

However, when I change the resources to:
     res_at_cnLevelSelectionMode = "ManualLevels"
     res_at_cnMinLevelValF = 1
     res_at_cnMaxLevelValF = 13
     res_at_cnLevelSpacingF = 1

I get the following:

Which shows no colors at all, when I'd expect it so show the single
yellow color between 2 and 3 for the entire map. Unfortunately I do
need the min/max settings to be 1/13 respectively, so I can't rely on
the AutomaticLevels for the contours, as I need one constant
temperature scale to correspond to several maps (other maps not
shown, but the range for all maps I need to produce go from 1 to 13).

I'm at a loss as to what to modify to get the colors/contours to show
up, and will try anything suggested. I've put my script code at:

As well as the data (26MB):

I'm hoping there's something basic that I'm doing wrong or an easy
solution. I'm using NCL 5.1.0.

Thanks for any help.
