Thunderstorms Day and Night. What is The Difference?
Thunderstorms are most likely to form when the temperature of the air decreases with height pretty rapidly–for example, when it’s hot at the ground and cold aloft. Thunderstorms that form at night occur in the absence of heating at the ground by the sun. Consequently, the storms that form at night are usually “elevated,” meaning that they form aloft above the cooler air near the ground, rather than near the ground, which only during the day can get warmer.
There aren’t nearly as many measurements available of temperature and moisture, which is needed to fuel thunderstorms, above the ground as there are at the ground, so predicting where storms will form at night is much more challenging.
All thunderstorms produce dangerous lightning, both during the day and at night. Storms that form at night are likely to produce hail, damaging winds and flooding rain. Tornadoes, however, are much more likely during the day, especially during the late afternoon and early evening, not at night. Tornadoes are also much more common in the spring than in the summer in most parts of the country.
