Pilots that live and fly along the west coast of the U.S. are very familiar with the marine layer. As the sun sets the marine layer moves in blanketing coastal airports with a low stratus deck and sometimes fog and reduced visibilities at the surface. By the late morning or early afternoon, the heating of the day initiates atmospheric mixing which promotes the dissipation of the marine layer. In this workshop, we will look at how a special version of the GFS Model Output Statistics (MOS) guidance can help a pilot determine when this very low IFR event will likely end.
