A weak low pressure system brought light showers and areas of fog to the Carolinas and southeastern Georgia during the morning hours.

Several record lows were reported yesterday morning, including Washington, Dulles with 53 degrees and Pittsburg with 51 degrees. The remainder of the East experienced fair weather.

A few severe thunderstorms moved across Kansas, Missouri, and Arkansas during the pre-dawn hours. One severe storm generated wind gusts of 65 mph in Ellis, Kansas.
