The dry spring pattern continued through most of May across the Oklahoma Panhandle before an abrupt change to a wet pattern over Memorial Day weekend. Prior to the start of the rainy weather, 3- to 4-year precipitation deficits rivaled those of the worst periods during the 1930s Dust Bowl and 1950s droughts of record. Most of the Panhandle received at least 1 inch of rain over the last 10 days of the month, and many areas received between 2 to 5 inches. Short-term dryness continued in the far western and eastern Oklahoma Panhandle. Widespread Exceptional (D4) Drought conditions at the start of May improved to a mix of Extreme (D3) and Exceptional Drought conditions at the end of the month. Guymon recorded 2.29 inches of precipitation for the month (0.15 inches below normal).
Soil moisture was rated from very short to adequate by the end of May, though soils were dry for most of the month before the onset of the rainy pattern. Farmers were rushing to plant summer crops, while most winter wheat had either been lost due to spring dryness or was being harvested. Rangeland quickly greened up following the rain, though range and pastures continued to be rated mostly in poor condition following several years of drought. Upper soil zones were greater than 40 percent full in the central Oklahoma Panhandle and between 20 to 30 percent full in the western and eastern parts of the Panhandle. Deeper soil zones were still drier, rated between 10 to 30 percent full. The Palmer Drought Severity Index indicated a rating of Severe Drought conditions for the Oklahoma Panhandle. A governor's burn ban was in effect for the Oklahoma Panhandle counties to start the month, but all burn bans were lifted by the end of the month.
Reservoirs and stream flows across the majority of the Oklahoma Panhandle were at below normal levels.
Economic losses due to the drought through May were predominately the result of supplemental watering, winter wheat losses, reduction of cattle herd sizes, and supplemental feed for cattle on drought-thinned rangeland and pastures.
