June 6, 2003: Squall Line w/ Biological Scatterers Author: Pam Heinselman, CIMMS/OU Last Updated: 11 June 2003

Forecast/Weather:

On 6 June 2003, a northeast-to-southwest-oriented squall line developed over northwest Oklahoma and moved southeastward across Oklahoma. While moving over KOUN, polarimetric signatures indicated the presence of biological scatterers both ahead of and behind the squall line between 2:14-8:40 UTC (see Figs. below).
