Inswing door over the rising pitch on a porch floor
I can see four options, two of which have been mentioned so far:

Increase the threshold height
I can see this going poorly, as a trip hazard at the top of some stairs
Using an out-swing door instead
This is probably the simplest option, but can look odd from an exterior perspective
Use a drop-down weather strip with enough clearance
It could look a bit odd when the door is closed, but it looks like there are options for up to 1 5/8&quot; (42mm) of height difference between the door being open and shut.  See this supplier for an overview.  Probably the most expensive.
Use a &quot;rising butt&quot; hinge.
These lift the door as it swings in, and can provide maybe 1/2&quot; of lift.  They are also self-closing by design.
