Lacy clouds that form at high altitudes are cirrus clouds. These types of clouds usually form before there is a change in weather. These clouds form above 20,000 feet, and they indicate fair weather.
no
Stratus clouds typically form at low altitudes, Cumulus clouds form at varying altitudes depending on their type, and Cirrus clouds form at high altitudes. Stratus clouds are usually seen as layered and overcast, Cumulus as fluffy and white, and Cirrus as thin and wispy.
cirrus
Cirrus clouds form at higher altitudes because they are composed of ice crystals that require cold temperatures to exist. These clouds typically form in the upper troposphere where temperatures are low enough for the ice crystals to form and remain suspended in the air.

just high altitudes
Cirrus clouds are high altitude clouds occurring between 17,000 and 40,000 feet
up high!
Cirrus clouds form at high altitudes and appear thin and wispy. They are composed of ice crystals and do not typically produce precipitation.
Cirrus
Very high wispy clouds are called cirrus clouds. They form at high altitudes and are composed of ice crystals. Cirrus clouds are often indicators of fair weather but can also signal approaching storms.
