On the Figure 19 Low-Level Significant Weather (SIGWX) Prognostic Chart legend, which symbol denotes "moderate or greater turbulence"?

Why: Figure 19's legend labels the yellow dashed/scalloped line as "moderate or greater turbulence," distinct from the solid blue jagged line (freezing level at the surface) and the red outlined area (ceiling less than 1,000 feet and/or visibility less than 3 miles).

• Confuses the turbulence line with the freezing-level symbol — the legend assigns the solid blue jagged line specifically to "freezing level at surface," a separate chart feature.
• Confuses the turbulence line with the ceiling/visibility outline — the legend assigns the red outlined area to the IFR ceiling/visibility criterion, not turbulence.
