June 25-26, 2003: MCSs Author: Pam Heinselman, CIMMS/OU Last Updated: 23 July 2003

Forecast/Weather:

On 25 June, two convective lines began to develop over north-central and southwest Oklahoma. The more northern line evolved into a squall line, producing locally heavy amounts of rainfall. These lines moved southeastward across Oklahoma between 20 UTC 25 June and 13 UTC 26 June. A new region of convective cells developed over southwest Oklahoma during the later morning hours of 26 June, producing light rainfall.
