A rare dryline case that took place on 19 March 2003 across the Southeast was studied using synoptic weather maps, model back trajectory simulations, soundings, satellite and radar data, and data from the Mobile Integrated Profiling System (MIPS) from the University of Alabama in Huntsville (UAH). The dryline provided an area of moisture convergence at lower levels and, combined with strong dynamics, initiated a severe weather outbreak across the Southeast. The Storm Prediction Center issued convective outlooks based on the location of the dryline and modified them throughout the forecast period. The MIPS recorded data indicating times of dryline passage and data corresponding to boundary layer processes in this region before, during, and after dryline passage.
