 Grand Forks, Devil's Lake, Minot, and Williston. Those were the eight reporting stations in all of North Dakota for a great many years officially. You had co-op observers at local spots that recorded data that wasn't reported every hour but just was then filtered for monthly data. So there's been a lot of changes in that realm. Why do they say then there's rotation detected when there's a tornado watch but you said every thunderstorm has rotation?
