Severe convective weather returned to the US on Monday with the NWS issuing a number of Tornado Warnings over the Louisiana and Mississippi area. Having significant outbreaks during the month of November is certainly not out of the ordinary as the transition month features the classic clashes of air masses over the southern US. The featured chart presents the unofficial IEM computed yearly date of maximum number of Tornado Warnings issued. Each bar is labelled with the date and the number of warnings issued for that date. The months are labelled at the bottom with the number of yearly maxes for that month. Only July is shown to have had no yearly maxes since 1986, which makes sense as the month has the least frequent aforementioned clashes of strongly contrasting air masses. The overall maximum is the outbreak of 27 April 2011 with a mind bending 463 Tornado Warnings.
