The center of upper level high pressure drifted westward into Arizona on the 7th and allowed stronger northwest flow to develop aloft over northeastern New Mexico. A very unstable atmosphere developed toward the late afternoon hours as moist low level southeasterly flow combined with strong afternoon heating and stronger winds aloft. The first thunderstorms developed around the Vermejo Park area where hail over two inches was reported. Storms continued to increase in coverage around Colfax and Union counties while pushing south toward the Interstate 40 corridor. Several storms went on to produce one to two inch hail with high winds and torrential rainfall.
