Cold Front
A cold front tends to give less warning of its approach because it usually moves faster than a warm front and has a narrower band of clouds and weather. If the cold front is active enough to produce thunderstorms, anvil cirrus clouds may spread ahead of the front as a warning of its approach. The other cloud types associated with a cold front are mostly cumuliform or stratocumuliform, with mid-level altocumulus giving way to lower stratocumulus and intermittent light precipitation if there is only slight airmass instability. With significant instability, vertically developed cumulus or cumulonimbus with showers and thunderstorms will form along the front.

Famous quotes containing the words cold and/or front:
“If you see one cold and vehement at the same time, set him down for a fanatic.”
—Johann Kaspar Lavater (1741–1801)
“I may be able to spot arrowheads on the desert but a refrigerator is a jungle in which I am easily lost. My wife, however, will unerringly point out that the cheese or the leftover roast is hiding right in front of my eyes. Hundreds of such experiences convince me that men and women often inhabit quite different visual worlds. These are differences which cannot be attributed to variations in visual acuity. Man and women simply have learned to use their eyes in very different ways.”
—Edward T. Hall (b. 1914)
