980622 - VORTEX crews were mobilized to intercept storms that were forecast to form on an old outflow boundary (from the previous nights' MCS activity). It was hoped that these storms would move northeast and into both better shear and better moisture. As is often the case, the atmosphere had other ideas. Convection formed on the foothills and moved very slowly to the east. This air was considerably drier than was necessary for supercells. VORTEX played a waiting game until the storms moved farther east. By late afternoon, one cell had begun to acquire supercell characteristics and intercepts began. A lack of good westbound roads limited our options but numerous north-south transects were completed in the inflow region. The storm diminished in strength during the early evening hours and operations were terminated at sunset. Shortly thereafter, the cell moved into better moisture and became severe once again with large hail and significant rotation.
