The upper level high center shifted well south and east of New Mexico by the 13th and forced stronger westerly flow aloft over the region. The combination of abundant low level moisture in place over eastern New Mexico along with a weak frontal boundary sagging into the area provided the focus for strong to severe thunderstorms with torrential rainfall. A cluster of storms that repeatedly developed over the same area of the east slopes of the Capitan Mountains produced flash flooding near Arabela. State road 368 was closed as several feet of water rushed across the roadway. Union County was the epic center for numerous storms that produced large hail through the afternoon. Hail up to the size of golf balls was reported around Sedan. Yet another round of heavy rainfall between one and two inches impacted much of the Caprock area.
