An enhanced risk of severe thunderstorms will exist across most of eastern Oklahoma and western Arkansas Friday evening. A strong upper level jet will move across the area, with a surface warm front extending from northeast OK through the TX panhandle. Storms are expected to develop near the dryline or along the warm front late Friday afternoon. The storms will eventually organize into a large complex, with a threat for heavy rain and flooding.
Widespread flooding is likely Friday night through Sunday morning across portions of central and eastern Oklahoma through western Arkansas. Flood watches are in effect for this time for the potential of 4 to 8 inches of rain with locally higher amounts. This will result in flash flooding and river flooding for portions of the area given recent heavy rains and saturated soils.
