Tornado reports of April 12, 2022


Last week we saw two episodes of severe weather in parts of eastern Nebraska and western Iowa. While the first afternoon severe weather surge stayed mostly outside our observation area and affected northwest and north-central Iowa, the severe weather surge affected most of us.

Severe thunderstorm warnings were mostly for wind gusts of 60 to 70 mph and hail the size of a quarter, half dollar or ping pong ball. However, we have issued several tornado warnings. After the storms, National Weather Service reports and survey crews confirmed there were four tornadoes in our area as of Tuesday.

We had two confirmed tornadoes in Nebraska and two confirmed in Iowa. The first tornado occurred in Seward County near Goehner. It was a rapid rotation confirmed by a trained storm spotter and video evidence. Fortunately, there was no damage. However, without damage to the NWS to be studied, it will be considered as EF-U or EF-Unknown. I have attached the local storm report and a screenshot of the radar imagery at 6:43 p.m. on Tuesday evening at the approximate time the tornado formed.
