A deep, closed upper level low pressure system was observed over central Alabama on the morning of May 28th. The east winds around this low, allowed deep sub-tropical moisture from the Atlantic to move into lower Mid-Atlantic region. Areas of rain developed across the mountains by late morning, and gradually increased in coverage due to the sustained 25 to 30 knot (850mb) moisture inflow. Precipitable water values were observed in the 1.2 to 1.3 inch range through the day into the early morning
