As mentioned in some of the earlier practice analysis feedback/answers, situational awareness is critical to performing a comprehensive and accurate frontal analysis. This is especially true for fast-moving fronts, like cold fronts or drylines, as well as fronts that are changing type (e.g., cold fronts or warm fronts stalling and becoming stationary, or vice versa). Without examining prior maps over several hours we often cannot truly tell what kind of front we should analyze at a density gradient. Let’s investigate the usefulness of examining previous frontal analyses other observations in the next two examples.
