What area of the U. S. did these severe blizzards, that happened during the same year as Schoolhouse Blizzard, affect?
Schoolhouse Blizzard "This article is about the blizzard in the Great Plains of the United States. For the blizzard during the same year in the Eastern United States and Canada, see Great Blizzard of 1888."
Winter storm warning A winter storm warning (SAME code: WSW) is a statement made by the National Weather Service of the United States which means a winter storm is occurring or is about to occur in the area, usually within 36 hours. Generally, a Winter Storm Warning is issued if the following criteria, at least, are forecast: usually between 4 in to 7 in or more of snow or usually 3 in or more of snow with a large accumulation of ice. In the Southern United States, where severe winter weather is much less common and any snow is a more significant event, warning criteria are lower, as low as 1 in in the southernmost areas. (Thus, as you go from south to north the necessary accumulations get higher.) A warning can also be issued during high impact events of lesser amounts, usually early or very late in the season when trees have leaves and damage can result. Winter Storm Warnings are issued when winds are less than 35mph; if the storm has winds above this wind speed, it becomes a blizzard warning.
