Multiple rounds of thunderstorm activity moved across eastern Oklahoma on April 30th into the morning hours of May 1st as a cold front slowly moved through the area. Atmospheric moisture was unseasonably high and steering currents were parallel to the front, both of which contributed to widespread, heavy rainfall as thunderstorms were very efficient rain-producers and tended to move repeatedly over the same areas. Most of eastern Oklahoma received two to three inches of rain, with higher totals of four to seven inches across portions of northeastern and southeastern Oklahoma. This widespread, heavy rainfall resulted in moderate flooding of the Neosho River near Commerce, the Spring River near Quapaw, the Illinois River near Tahlequah, the Poteau River near Panama, and the Kiamichi River near Antlers.
