A powerful storm system brought a round of thunderstorms into the state on Tuesday prompting the issuance of a Tornado Watch and subsequently two Tornado Warnings for portions of Iowa. Both events are difficult to find analogs to in the recent archives maintained by the IEM. This would have been the first Tornado Watch in the state since at least 2006 and first Tornado Warning since at least 1986. The featured chart presents the number of tornado warnings issued by month and year for Iowa. The highlighted section shows no events for the months of January and February until the two yesterday!
