Especially if sea level pressure is 29.92inhg by default, 30.06inhg, 30.12inhg would be low pressures.

Hi,
I am confused as to why the surface map has a "low" pressure with its center pressure reading at 30.21inhg?
This is an error and a very easy fix.

Add "more layers" view capabilities in the right sidebar when the forecast location is present.
