The episode as NWS BOU wrote it up.
A landspout formed along a colliding boundary east of Eaton. The tornado flipped over 100 small cow huts. None of the calves were injured, although several were chained to the shelters and had to be untangled. Several feed bags were scattered around as well.

Area Forecast Discussion National Weather Service Denver/Boulder CO 325 PM MDT Fri Mar 22 2019 .SHORT TERM...(This evening through Saturday) Issued at 325 PM MDT Fri Mar 22 2019 Latest satellite and radar imagery shows the convection developing, although the majority of this so far has been to our south. It will continue to advect northward and fill in through the evening hours, as moderate QG ascent combines with the unstable airmass. The track of the upper level low, from the Colorado/New Mexico border into east central Colorado tonight, would suggest a period of upslope. However, along the Front Range, we expect a rather quick transition to a slight downslope NNW component by late evening. Along this wind shift and mid level convergence, we will see strong frontogenesis, and an enhanced band of precipitation with higher rates. That band should shift slowly east to just east of the I-25 Corridor late this evening, and then possibly stall overnight as low pressure system deepens, effectively keeping a prolonged period of frontogenesis and enhanced precipitation over our plains. As a result, we will continue to push up our QPF numbers for just east of the I-25 Corridor. At the same time, the heavier precipitation will likely drive down snow levels a little more, especially over the Palmer Divide where a deep northerly upslope component develops. The combination of these two factors will likely lead to a quicker changeover and thus more snow accumulation. We have boosted amounts toward the middle range of the short term guidance, relying heavily on HRRR vairable method snow accumulation. This is normally much better than a typical 10:1 ratio in these marginal temperature events where there is considerable melting. Will still have to watch the latest trends closely as just a degree or two could make a significant difference in snow amounts and accumulations. Right now, we expect the brunt of the snow to occur overnight, with mostly slushy conditions, so impacts shouldn't be too much for areas from Douglas into Elbert/northern Lincoln county. Best estimates for those areas would be 1-4 inches. Around Denver, look for mostly rain although a few wet snowflakes will likely occur over the southeastern sections of town later tonight, perhaps just enough for a dusting. In the mountains, snow showers, some heavy, early this evening will gradually decrease later in the evening and overnight as airmass stabilizes. On Saturday, the morning rain/snow east of the I-25 corridor plains will graudually diminish to showers as the storm system pulls away. A few snow showers will linger in the mountains with enough orographics and shallow moisture. Temperatures will be slightly cooler, but a little downslope will help push readings to just shy of normal levels along the I-25 Corridor. It will be a little breezy in the post trough airmass as well. .LONG TERM...(Saturday night through Friday) Issued at 325 PM MDT Fri Mar 22 2019 Moisture will remain over the mountains Saturday night and Sunday as westerly flow aloft will continue across the state. This will keep light scattered snow showers going west of the Continental Divide. The flow aloft will not be particularly strong, but stability will be low, which will allow the orographic shower activity to continue. By Sunday afternoon and evening, heights will be rising and flow aloft is forecast to turn more northwesterly. However, we will be under the left exit region of a broad upper jet, while the airmass remains marginally unstable. The result will be a chance of showers moving out over northeast Colorado through the afternoon and evening. Temperatures will be around seasonal normals. After Sunday evening, heights over Colorado will rise in earnest with dry and warmer conditions across the forecast area through much of the week. Wednesday looks to be the warmest day of the week with highs into the lower 70s across the plains. The upper ridge is forecast to be moving eastward on Thursday with flow over Colorado becoming southwesterly. Friday and Saturday look cooler and unsettled as a broad upper trough will be in place over the state. Mountain areas will pick up some more light snow while the plains see a mixture of rain and snow, depending on the temperatures and the time of day or night. && .AVIATION...(For the 18Z TAFS through 18Z Saturday afternoon) Issued at 325 PM MDT Fri Mar 22 2019 Rain showers will become more widespread 00Z-06Z as a storm system moves across the area. An isolaed thunderstorm is still possible until about 02Z. Look for MVFR ceilings and visibility to develop with the onset of steady and heavier precipitation this evening. Showers may mix with snow after 05Z or so at KDEN and KAPA, but any snow accumulation would be less than a half inch and confined to elevated surfaces, if precipitation was able to turn over to all snow. Conditions will improve 09Z-12Z with precipitation shifting east of KDEN. Then VFR will prevail Saturday, with north/northwest winds gusting to around 20 knots. && .BOU WATCHES/WARNINGS/ADVISORIES...

Rain will become more widespread across the plains this evening, and push slowly east overnight. Small hail, cloud to ground lightning, and a brief period of heavy rain and gusty winds to around 35 mph can be expected from the storms. Across the mountains, moderate to heavy snow showers will occur, resulting in some slush and snow accumulation on roads. Total accumulations of 3 to 6 inches can be expected in most mountain areas above 9500 feet by the time snow tapers off by mid evening. In the lower elevations, rain will eventually mix with or change over to snow over the Palmer Divide and the Wyoming border area. A couple inches of slushy snow accumulation will be possible in those locations, but elsewhere across the plains mostly rain will fall. .DAYS TWO THROUGH SEVEN...Saturday through Thursday An upper level storm system will move slowly east of the area on Saturday. Rain will continue over the plains in the morning but will gradually end from west to east during the afternoon. In the mountains there will be a good chance of snow showers with a few inches of wet snow possible. Drier weather is expected late Saturday into Sunday morning with more mountain snow Sunday afternoon into early Monday as another surge of Pacific moisture moves across the state. The plains may see another round of rain or snow showers Sunday night. Warmer and drier weather is expected for Tuesday and Wednesday as upper level high pressure builds over the Rocky Mountain Region. .SPOTTER INFORMATION STATEMENT...
