A well-developed squall line with embedded bowing structures moved east-southeast at 45 knots into a destabilizing air mass over the Mississippi River Valley. The line was located to the south of a quasi-stationary front in a moist air mass, with surface dew points in the mid to upper 60's. Surface temperatures in the lower 80's contributed to moderate instability, which helped to maintain the line of storms into the early evening. Damaging winds and marginally severe hail accompanied the strongest storms.
