We're monitoring some strong to severe storms in South Dakota moving into North Dakota. The storm by Bison, SD is being monitored more closely, as it is producing multiple warnings and also has a pink core. What a pink core indicates is that the storm is very healthy and strong. It also could be an indicator or how the storm could stick around for quite a while.
Northern Plains infrared imagery indicates cloud tops are extremely tall. Checking our advanced radar, it looks like the storms have cloud tops scanned to at least 65,000 feet- quite a spectacle. Storms will continue to blossom in the area of North Dakota back into South Dakota. If these first cells are a sign of what's to come, this certainly will be a long night.
