We headed home late in the afternoon after visiting our daughters in southeast Iowa. A small thunderstorm was leaving the area we drove north of the town of Mt. Pleasant. We hadn’t paid attention to the weather notices since we were busy visiting. A severe storm watch had been issued. This small storm looked quite energetic. I remarked how the trailing part of a storm is often where funnel or tornado activity originates. Thank you spotter training 101. In all my years of watching weather, I have not seen a tornado in real time.
We approached the rear of the storm as we drove north. The arrow in this radar map shows our location. The sky was bright to the west and dark to the east. A few cloud formations appeared low to the northwest. I was not driving the car and watched one funnel shape in particular. It was small and rotating very fast. We pulled to the side of the road to avoid driving into the path of it in case it got to the ground. It broke up.
We drove another mile and watched the same cloud form another funnel. This one was larger and longer. We pulled off the main highway to a side road for a better and safer view. The funnel was but a half mile away, still to our northwest. Full screen gives a more detailed view.
I called the NWS reporting phone number to give them details on location and movement they need to issue warnings. We watched the storms later as they moved into Illinois. Some storms caused heavy rains and hail. Extensive tornado damage occurred in the small town of Cameron about 30 miles east of where we watched this funnel.
