One resident wrote on X, “Our sky is so yellow orange right now I can't even get the color with my camera.”
Another added, “The sky right now is this freakishly bright glowing yellow color and it’s making my whole house look creepy but my camera won’t register it unfortunately. Did get a cool pic but just imagine everything is bright yellow lol.”

Why Does the Sky Turn Yellow?
A yellow sky doesn't always mean a tornado is imminent or that you need to seek shelter immediately. In fact, storm clouds of various types can cause the sky to take on a yellowish tint. This is especially when the sun's rays filter through heavy moisture or dust in the atmosphere.
