Squall lines with an almost unbroken line of threatening dark clouds and sharp changes in wind direction, generally precede a cold front. A series of brief showers accompanied by strong, shifting winds may occur along or some distance ahead. Cumulus and cumulonimbus clouds are most likely to accompany a cold front. A cold front moving in from the northwest can produce thunderstorms, hail, and then rapid clearing. In the Northern Hemisphere, a line of cumulonimbus clouds may be observed. Brief, violent showers frequently accompanied by thunder and lightning are usually associated with the passage of a cold front. In the Northern Hemisphere, winds veering sharply to the west or northwest with increasing speed. As it passes, the pressure rises, the temperature drops, humidity decreases, and winds become gusty. Visibility improves rapidly.
