Cold Sector: A portion of a low pressure system dominated by cold air. The cold sector is found to the northeast of the low, ahead of the warm front all the way back to the west and south behind the cold front. Cold sector conditions vary but near the center of the low, and ahead of the warm front, general cloudiness is a good bet along with stratiform precipitation (precipitation that is uniform and constant, see full definition below), while behind the cold front, cold and clear conditions can be found.
