The GOES-R products demonstrated in the summer experiment focused on short-term prediction and observations of convective initiation. GOES-R IR radiances and total lightning threat forecasts from the NSSL-WRF, Cooperative Institute for Meteorological Satellite Studies cloud-top cooling rates, and the University of Alabama Huntsville Satellite Convection Analysis and Tracking Strength of Signal were some of the products evaluated for their usefulness in providing meteorological support for aviation impacts to flight routes and terminals. This presentation will focus on two high-impact cases that occurred during the summer experiment. The first occurred on 6 June when a decaying mesoscale convective vortex forced convection that impacted the terminals in and around Dallas, Texas. The second impacted high-altitude jet routes within the northern portion of the aviation Golden Triangle on 12 June. In both cases, hundreds of flights were impacted and it will be shown how GOES-R demonstration products can provide decision assistance to AWC and the new National Aviation Meteorologists within the Federal Aviation Administration Command Center.
