Composites of Heavy Rain Producing Elevated Thunderstorms in the Central United States

Figure 9

EAX CWA composite for 0–3 hr prior to event time showing (a) average mean sea level pressure (solid black, hPa), 1000–500 hPa layer thickness (dashed brown, dkm), and precipitable water (color-filled, mm); (b) average mean sea level pressure (black, hPa) and 75–25 percentile spread (color-filled, hPa); (c) mean thickness (black, dkm) and 75–25 percentile spread (color-filled, kts); (d) mean precipitable water (black, mm) and 75–25 percentile spread (color-filled, in) (e) regional spaghetti plot of 50 mm of precipitable water from each composite member (each is a different color). The star is located at the centroid of the CWA. Heavy dark line in Figure 9(a) is the cross-section line in Figure 10.
