Description: A sample weather map from 1910 of the United States showing typical weather patterns and a winter storm event. The map shows a low pressure system in the Northern Plains and in the Northeast, a high pressure system over the coastal Pacific and Ohio Valley region. The map shows prevailing wind directions flying with the arrow symbols from areas of high pressure towards areas of low pressure, lines of equal barometric pressure (isobars) reduced to sea level, clear–weather temperatures (30 to 40 degrees Fahrenheit) from the arid regions moving into the low pressure system, and the rainy–weather temperatures averaging 50 degrees Fahrenheit.
