Environmental soundings from the 36-member ensembles with temperature (thin red lines) and dewpoint temperature (thin blue lines) at 2100 UTC May 8 ((a) and (b)) and 0000 UTC May 9, 2003 ((c) and (d)) from the Oklahoma City (KOKC) station from the FixedPhysics and MultiPhysics mesoscale ensemble data assimilation systems. Overlaid are the ensemble mean (thick lines) and radiosonde observations (black) at 00 UTC May 9, 2003 ((c) and (d)).
