KXAN's First Warning Weather Team says this is actually a common occurrence during the summertime as prevailing east winds blow huge plumes of dust from the Sahara Desert. The dust actually suppresses hurricane formation during its trek across the Atlantic. 

Rain can eliminate the dusk from the mid and low-level atmosphere, but we do not have any chances of that going forward.
