The first severe weather episode of 2007 occurred across southeast Missouri during the evening.  A cold front pressed southeast across the region during the afternoon as a wave of low pressure shifted east along the front into the Ozarks of northern Arkansas.  Southerly flow ahead of the low brought warm moist air northward as temperatures reached the 60s.  The atmosphere destabilized enough by late afternoon to allow for the development of thunderstorms over southeast Missouri. These storms were prolific hail producers.
