Excessive heavy rainfall was widespread across the southern half of Northeast Texas  during the morning hours of May 18th. This convection developed from an upper level disturbance that moved into the region from Central Texas. Moisture was plentiful across the region as the upper level flow was from the southwest. This allowed the disturbance to tap moisture from not only the Eastern Pacific but also the Gulf of Mexico. These storms trained across the same general area resulting in some impressive rainfall totals. The end result was widespread flooding across much of the region.
