Cirrus clouds form by the uplift of warm, moist air along an incline of cooler air ahead of the front, for example a warm front. They are so wispy because they are actually ice crystal clouds that form at high altitudes in the upper troposphere. There are 3 types of cirrus clouds: 1. Warm Front Cirrus - Form out ahead of an approaching warm front and are blown around by upper level winds that give them their wispy appearance. 2. Anvil Cirrus - Form off of thunderstorm anvils and can signal that a thunderstorm is nearby. 3. Mares Tail Cirrus - Cirrus clouds that are blown around by upper level winds such that they look like mares tails. Hope this helps! :)
