A long-lived mesoscale convective system (MCS) accompanied by strong winds at its leading edge, i.e., a Derecho, moved through the central US on 29 June 2023. The animation above shows GOES-16 Clean Window Infrared (10.3 \u00b5m) imagery at 15-minute intervals from 0100 UTC through 19 UTC on 29 June 2023. The imagery also includes 5-minute accumulations of Flash Extend Density from the Geostationary Lightning Mapper (GLM), and GOES-derived Lifted Indices. Of particular note is the corridor of instability over northern Kansas\/southern Nebraska, and the large pool of instability of Illinois, that helped sustain the thunderstorms within the MCS as the feature propagated eastward. The system started as a supercell with a pronounced enhanced V as well (shown below) before evolving into an MCS overnight. Numerous reports of severe weather occurred on both 28 June<\/a> and 29 June<\/a>, as shown below.<\/p>\n\n\n\n

The high winds caused blow-over in some cornfields in central Illinois (near Farmer City in DeWitt County) to the west of Champaign-Urbana, as shown in this tweet<\/a> from Andrew Pritchard<\/a>. He also showed damage in Farmer City<\/a>.<\/p>\n\n\n

The earlier thunderstorms produced a few tornadoes in Nebraska\/Colorado, hail as large as 4.00 inches in diameter in Wyoming\/Colorado and wind gusts exceeding 80 mph in Colorado — while the later thunderstorms exhibited an impressive display of overshooting tops across Illinois (having cloud-top infrared brightness temperatures in the -80 to -86\u00baC range, shades of white embedded within darker black areas) as the MCS produced several wind gusts of 80 mph and higher.\u00a0<\/p>\n

The storm that grew into this MCS had both an Enchanced-V structure, the accompanying warm trench, and an obvious Above-Anvil Cirrus Plume, all hallmarks of severity, as shown in the toggle below.<\/p>\n\n\n\n

Note that a corridor of instability remains along the Kansas\/Nebraska border at the end of the animation up top, and as shown below. Convection is forming over the high plains of Colorado. Will convection follow a similar path on the 29th into the 30th?<\/p>\n\n\n\n
