Parts of the country recorded record warmth at one end of the week and other parts of the United States reported record low temperatures at the other end of the week.
Late last week, snow developed across the central Plains, ending a period of mild, favorably dry weather across the nation’s mid-section that allowed summer crop harvesting to near completion in many areas. Weekly temperatures averaged at least 5°F
above normal from Montana to northwestern Kansas. Farther east, however, late-week precipitation from the Mississippi Valley eastward was another setback for Midwestern and Eastern producers attempting to complete winter wheat planting and
summer crop harvesting. Rainfall totaled 2 inches or more in portions of the Mid-Atlantic States. In addition, cold conditions dominated the eastern half of the country for much of the
week, with bitterly cold air sweeping across the Great Lakes and Northeastern States on Thanksgiving Day. Weekly temperatures averaged 10 to 15°F below normal across much of the Northeast.
Early in the week, cold conditions affected much of the central and eastern U.S. On November 18, daily record lows plunged to sub-zero levels in many locations. With a low of -7°F, Houlton collected another daily record low on November 19. By mid-week, however, warmth returned to the northern High Plains.
