Surface analyses (below) depicted a cold front that was moving northward across that area during the day — a narrow cloud band denoted part of the leading edge of this cold front. The circulation around a compact area of high pressure that developed along the coast (south of the cold front, at 0000 UTC) acted to transport some of the blowing dust farther inland (westward).
