The pressure patterns over the Northern Hemisphere often steer these Saharan Air Layers westward across the Atlantic Ocean, and in some cases that dust can travel as far west as Texas and Central America. Early this week, dust will return to parts of the southern US, traveling from Texas and Louisiana on Monday to the Mid-Mississippi River Valley by Wednesday, moderating as it moves. Multiple days of dust will likely fill the skies of southeastern Texas and much of Louisiana, making for hazy or filtered blue sunshine and lower air quality, which may be harmful to some.
