The downdraft convective available potential energy (DCAPE) and downdraft convective inhibition (DCIN) are evaluated for two groups of elevated convection events, both severe and non-severe. Ten recent years of the online Storm Events Database were examined (2004-2013) for the entire CONUS in an effort to identify cases of elevated convection. As of this writing, the non-severe elevated convection pool had not been finalized. However, 42 events of severe elevated convection were identified, all east of the Rocky Mountains. Each of these events had at least 5 reports of severe weather, and occurred at least 50 statue miles north of a thermal boundary in keeping with prior work. Additionally, the primary severe weather threat in these cases was hail, followed by winds, and finally a few tornado reports; this also corroborates prior work. Both plan view and sounding analyses of the severe pool suggest that elevated severe weather is more likely as |DCAPE|>|DCIN|.
