We've had days here, in the winter, where we've
left the ground where the temp is -20°C, and found -18°C at 3000' agl.

My mistake. It was -20°C on the ground and +18°C at 3000' agl.
A 38° difference. A difference in the "wrong" direction.

So the pressure must have been much higher at 3000 feet, according to the
reasoning given in your previous post.

You either do not understand or are unteachable. Perhaps this
is why you are limited to simming. I talked about inversions. I talked
about temperature and pressure for a *given* air mass. All you can do
is diss everything anyone says in a futile attempt to protect your
credibility.
