Radar loop of the tornado event. The top left image is base reflectivity (Z) and the top right image is storm-relative velocity (SRV). The bottom two images are correlation coefficient (CC) and spectrum width (SW). Low values of CC, combined with a SRV couplet or on a convergence zone, are a strong indicator of debris being lofted by a tornado. High values of SW can also denote the presence of a circulation.

2019 Iowa Tornado Summary  

     After a very slow start to the 2019 tornado season in Iowa with no tornadoes through May 21st, the season kicked into high gear almost overnight.  The season started with overnight tornadoes on May 22nd including two in southwest Iowa.  The stronger of the two was an EF2 tornado just southeast of Adair.  This tornado produced extensive damage to a home killing a 74 year old woman and injuring her husband.  The other tornado that night was an EF1 outside of Anita.  Two days later on May 24th, a pair of tornadoes occurred in the Iowa City area producing minor damage but fortunately no injuries or deaths.   Then on Memorial Day, six tornadoes occurred with two in northern Iowa and the other three in the far southeast.  The strongest tornado was an EF3 in Van Buren county where extensive damage was produced at a house near Cantril.  The finale to this active period in late May came on the 29th when 15 relatively weak tornadoes occurred in central and eastern Iowa.  While most of the tornadoes remained in open farmland, a few of them did produce damage in Hardin and Poweshiek county including one injury near Deep River.  This eight day period in late May accounted for 25 tornadoes across the state including one death and two injuries and accounted for just over half of the normal tornadoes Iowa experiences in a year.  The first tornadoes in June occurred on the 9th with three landspouts in eastern Iowa.  These tornadoes remained in rural areas producing little damage despite remaining on the ground for several minutes each.  An additional four tornadoes were observed on the 15th with a landspout north of Whitten in Hardin county which destroyed an old barn.  The other three tornadoes occurred in Des Moines county including two EF2 tornadoes southwest of Oakville. The final tornado of the month was a weak tornado in northwest Iowa near Terril.  

     Three tornadoes occurred in July and all were very short in length and remained in open cropland.  There was an uptick in activity during the month of August with six tornadoes reported.  This included three tornadoes in the morning on the 20th associated with a line of thunderstorms.  The strongest of these was an EF3 southeast of Indianola doing considerable damage to the Operators Union training facility, fortunately no injuries occurred.  There were seven tornadoes during September, but these remained in rural locations producing only minor to no damage.  Finally, on Novmeber 30th, a weak tornado occurred northwest of Panora passing through an unharvested cornfield and then two other agricultural fields before dissipating.  In total, 51 tornadoes have occurred in 2019 across Iowa with one fatality and two injuries.
