Subtropical moisture was better able to hold on over the Southeast Mountains, Raton Ridge and San Juan Mountains. Thus, afternoon upslope flow driven thunderstorms were more abundant further south. These storms moved into the eastern plains and brought some much needed rainfall to Las Animas and Baca County in the evening hours.
