While it is the heart of severe weather season, the recent two weeks have still been quite active across the country. The featured chart presents an IEM accounting of the number of NWS Tornado Warnings issued by calendar day (US Central timezone). The total for yesterday made for the fourth day of 2024 with over 100 tornado warnings issued. Yesterday also featured the first tornado emergency for the state of Michigan. Again, based on unofficial IEM archives, the record for number of 100+ tornado warning days is nine days during 2011. The second highest total was five days during 1998, 2003, 2005, and 2006.
