We threw in the towel around 8pm this evening when the storms all weakened considerably, but we managed to see a nice sunset and a few mammatus clouds under the anvil of a storm to our north. The shot on the left is from our live stream this evening... that's me taking a picture of the mammatus clouds.
Looks like we'll be in South or North Dakota tomorrow as a low travels from Colorado to South Dakota. The latest NAM computer model run indicates east winds along the ND/SD border tomorrow afternoon with good shear, dew points near 70, and EHI values of 3 or more. I certainly think that tomorrow will have more potential than today, but we'll know for sure by tomorrow morning. For now, the SPC has placed North Dakota and South Dakota under a 30% Slight Risk of severe weather for tomorrow. There's talk that they may upgrade to a Moderate Risk tomorrow morning, so we'll see how that pans out!
