Threatening sky

Quick trip to Carrefour to look at Laptops, I'm confused, there are so many to choose from, so if anyone has any helpful information please feel free to make suggestions. Driving out of Quesada, noticed the sky, stopped the car and quickly took this photo. It was weird as storm clouds in one direction and bright sunshine in the other. When we came out of Carrefour it was p*****g down.
