There are some stronger storms ongoing in the southwest portion of South Dakota this evening.
Some things to note are a slight hooking motion in some portions of the stronger storm cell cluster, and how the potential for hail is rising.
The image above is VIL, which, in the case where the number is higher, the likelihood for hail and bigger size the hail may be. We see a very high number in the storm cell cluster in the right portion of the radar.
These storms have also been dumping quite a bit of rain, with hourly rainfall totals coming at over 1 inch.
There is a severe thunderstorm watch over the area for these storm cells as well.
