Low Level Significant Weather Prognostic Charts forecast conditions from the surface to _____ feet MSL.

Low-level charts are designed to show significant weather hazards in the lower portion of the atmosphere, specifically from the surface up to 24,000 feet above mean sea level. This range captures the weather phenomena most relevant to pilots flying at low and mid altitudes—things like icing, turbulence, and ceilings/visibilities that impact approach and departure planning. The 24,000-foot limit is what defines this chart set; higher-altitude prognostic charts exist for the upper levels of the atmosphere, so options like 50,000 or 100,000 feet are not applicable here. A 10,000-foot span would miss much of the lower-layer weather the chart is meant to depict.
