1968 ; Bonin et al. 2015 ), allowing production of elevated instability. In these situations the LLJ carries moist warm air above the inversion, and the high wind speeds allow transport across hundreds of kilometers with air parcels eventually reaching their level of free convection if sufficiently lifted by a synoptic front, baroclinic boundary, elevated convergence, MCS outflow, or bore waves ( Trier and Parsons 1993 ; Augustine and Caracena 1994 ; Wilson and Roberts 2006 ; Berg et al. 2015

2019 ). There is a lack of studies examining impacts on severe convective storms that produce large hail, tornadoes, and damaging winds, which cause as much annual property damage and more deaths than hurricanes in the United States based on National Oceanic and Atmospheric Administration (NOAA) Storm Prediction Center (2012) . Hail produces roughly 60% of the annual average losses in the United States, compared to 20% for both damaging wind and tornadoes ( Gunturi and Tippett 2017

advection. Other studies have discussed nocturnal initiation being associated with bores and gravity waves ( Pitchford and London 1962 ; Whiteman et al. 2006 ; Knupp 2006 ; Koch et al. 2008 ; Browning et al. 2010 ; Marsham et al. 2011 ) or warm advection and mesoscale convergence within the exit region of the low-level jet (e.g., Tuttle and Davis 2006 ; Stelten and Gallus 2017 ). Wilson and Roberts (2006) noted that midlevel convergence and conditional instability were major factors in

solitary wave, finding that the wave passage reduced convective inhibition (CIN) and lowered the LFC, making CI more likely. However, other studies (e.g., Toms et al. 2017 ) have shown that propagating bores may lift parcels to their lifting condensation level (LCL) without producing CI. Thus, a better understanding of the mechanisms and conditions when these propagating wave structures trigger CI is needed. The present study analyzes nocturnal, elevated CI near an MCS outflow boundary during the
