That's because static and total pressure are ambient, not local - they change with altitude / speed.
What is concerning is this:
Notice sea level pressure is constant. So, it's not METAR at fault. It must be the atmosphere / aloft winds / AW interpolation and strange effects due to all three combined.
See how altitude and speed jump - did you (or AP) do this or was this a jump?
This is not of concern:
This is wind going from above 360 to below 360.
Wind direction getting "stuck", then jumping at 1800 seconds is somewhat concerning though.
