Just like humans, East Coast tornadoes work extra hours during the week and take it easier on the weekends. According to a new study, tornadoes and hailstorms are less likely to occur on a Saturday or Sunday. That’s because hail and tornadoes thrive on pollution, which is higher towards the middle of the week.

The study looked at summertime storm activity and found above-average rates of storms midweek and below-average rates on weekends. It turns out that this is because moisture likes pollutants: Water particles cling to those dirty little suckers, float up higher in the atmosphere, and create hail. Meanwhile, pollutants also end up indirectly making the air warmer, creating conditions in which tornado-birthing supercell clouds form more easily.

At least a tornado-filled workday breaks up the monotony, I guess? All things considered, we'd rather have our workday spoiled than our weekend picnics.
