March began with an upper-level low located west of Monterey County. The cyclonic flow around this low drew precipitation northward over the central California interior, and brought Bakersfield its only measurable rain (0.04 inch) for the first three weeks of the month. Fortunately, rainfall amounts over the central and southern San Joaquin Valley were light, as the heavy rains of the preceding three days of February had left the soil saturated and additional heavy rains could have caused flooding. The Southern Sierra Nevada foothills were not as lucky, as a debris flow covered part of Highway 168 near the Four Lane shortly after midnight on March 1st.
With the southerly flow aloft, the low advected warm and unstable subtropical air into the central California interior. Thunderstorms developed over the region on March 2nd, resulting in a funnel cloud that formed near Dos Palos. As the storm moved east during the night of the 2nd-3rd, skies partially cleared. This allowed for radiational cooling, and patchy dense fog developed in the Hanford-Lemoore area with visibilities of 500 feet or less at times. Also in the wake of the storm, a band of low clouds formed along the foothills and valley-facing slopes of the Southern Sierra Nevada, producing light (but measurable) rain during the evening of March 4th.
