Not that anybody is complaining other than storm chasers, but this year continues to be a very slow year for severe weather over the United States. The featured chart displays the combined number of Severe Thunderstorm and Tornado watches issued by the Storm Prediction Center since 1997. The second plot shows the number that likely had some coverage over Iowa and the third plot represents the percentage of these watches against the nationwide total. The totals this year, for the year to date period, are the smallest since 1997.
