The most significant heavy rainfall and flooding event of June occurred on June 19-24. During this period thunderstorms developed in the Oklahoma and Texas Panhandles and then moved through the western half of Oklahoma on three consecutive days on June 19-22. These storms also produced severe hail and wind gusts on June 21.Rainfall totals for the 72-hour period ending at 7:00 am CDT on June 22 reached 2 to 3 inches in a wide swath that included most of northwest, west central, north central, and central Oklahoma. Hardest hit was the Cimarron River basin in northern Oklahoma where storm total precipitation amounts of 5 to 6+ inches were observed in parts of Harper, Woods, Woodward, Major, Blaine, Kingfisher, and Logan counties. The subsequent heavy runoff produced by these rains generated flash flooding and riverine flooding in northwestern and central Oklahoma.
