980524 - The target area was northwest Oklahoma where upslope moisture advection was occurring and the shear profile would support supercells. By late in the afternoon it was clear that the atmosphere had other ideas as numerous supercells formed in south central Kansas and moved southeast into northern Oklahoma. VORTEX targeted a developing storm near Medicine Lodge and made numerous passes with all the mobile mesonet vehicles. Data collection was terminated when it became too dark to work. All vehicles carefully navigated their way home through the numerous supercells that continued to develop during the evening hours. The NOAA P-3, as part of MEaPRS, targeted these nocturnal storms and the developing mesoscale convective complex for a night of data collection.
