A deep plume of Gulf of Mexico moisture surged northwest during the early morning while a weak upper level trough drifted east over central New Mexico. A sharp dryline over far eastern New Mexico set the stage for strong to severe thunderstorms by mid to late afternoon. These storms produced large hail across portions of the area, including Union, Curry and Roosevelt counties. The largest stones fell around Sedan and Portales where golf ball to hen egg size hail was reported.
