Winds Around Cyclones
flowing counterclockwise in the northern hemisphere

Since winds flow in a counterclockwise direction around low pressure centers, look for a group of stations where the wind barbs reflect this type of wind pattern. For example, a counterclockwise wind pattern was observed in the states of Nebraska, Iowa, Minnesota and South Dakota (highlighted by the red arrow).
