- Warm frontal clouds. Strands of Cirrus cloud arrive well in advance of a weather system and warm front. The high clouds appear first because winds at that level are stronger and carry cloud farthest forward. The ice crystal cloud form thickens to a Cirrostratus veil toward the horizon and lower, unfrozen Altocumulus patches begin to show up as the frontal surface lowers.
