Scientists' best theory for why the sky sometimes changes to a yellow or greenish hue before a severe storm is that storm clouds of a certain thickness and water concentration act as a filter for the light that passes through them, according to The Guardian.

University of Reading's Rob Thompson said the yellow tint was most likely due to an influx of dust in the atmosphere that came from the Sahara, because the storm had passed through Africa before blowing through Europe. "It's not that unusual, it happens quite regularly.

It's a concept called rayleigh scattering. Shorter wavelengths are scattered more and longer ones are scattered less. This explains why the sky is blue. Sometimes, after a storm passes, the yellow/orange tint is a result of that reyleigh scattering.

A reader’s question about changes in sky colors before a storm. No one knows for sure – but there are a couple of theories about that weird greenish-yellow color you see before a storm. Storm clouds themselves may help make the color green — or the storm may just act to provide a dark backdrop, so that you can see the color.
Oftentimes, the sky will appear yellow when a thunderstorm occurs. According to the National Severe Storms Laboratory, thunderstorms most often occur in the late afternoon or early evening, around the same time when the sun is beginning to set. Though the sun is blocked by clouds, the process of a sunset still happens, and it still emits colors. Therefore, a yellow-ish-orange hue may become visible through the clouds.
Rayleigh scattering is related to the chemical composition of the atmosphere and occurs when the particles causing the scattering are smaller in size than the wavelengths of radiation in contact with them (this is why the sky appears blue most of the time). The yellow sky in this question is likely mostly owing to Mie scattering. Mie scattering is caused by pollen, dust, smoke, water droplets(the most likely culprit in this case), and other particles in the lower portion of the atmosphere ...
