The elevation at Checotah is only about 600’...... so if there is a high pressure system in the area, you can def see baro readings over 30”...... like right now.
All barometer readings at any reporting airport are corrected to sea level readings, not the actual barometer reading, so all airplane altimeters are reading alike when landing at that airport.
The FAA decided that long ago
All airplane flying above 18,000 Ft are suppose to set their altimeter to 29.92 until they are ready to land and then descend below 18,000 Ft.
