Dust from the Sahara Desert is likely to move over the area this weekend, according to the Joliet Weather Center (JWC) on Wednesday.
“Dust from the Sahara Desert continues to make its way westward and will likely move into our area over the upcoming weekend. We could see hazy milky skies, which could lead to vibrant sunrise and sunsets. Can’t rule out a thin layer of dust on surfaces either. If there is any rain during this time it might be mixed with this dust – often called dirty rain,” JWC reports.
The mix of pollution is the same reason why sunsets look more “red” than usual in Western states like Arizona.
