The typical afternoon thunderstorm forms when the sun heating the earth leads to instability in the atmosphere as warm surface air meets cooler air aloft. The time of the year we are most likely to have those conditions is the spring and summer. NOAA National Weather Service. Thunderstorms arise when layers of warm, moist air rise in a large, swift updraft to cooler regions of the atmosphere . There the moisture contained in the updraft condenses to form towering cumulonimbus clouds and, eventually, precipitation. Columns of cooled air then sink earthward, striking the ground with strong downdrafts and horizontal winds. The triggers for thunderstorm development can be tough to pinpoint in the summer. Lightning can strike during a snowstorm when the charge needs to be equalized, just like in a summer thunderstorm.
