   The survey recorded a tornado but could not put a number on it, most often because it crossed open country and damaged nothing a rating can be read from.

7 damage points were recorded along this path by NWS LBF, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EFU.

• Approximate end location of tornado. Location based on radar, photo, and video evidence. No damage was found.
• Location based off of radar and photograph/video evidence.
• Location based off of CC drop/TDS.
• Photographic evidence of tornado cycling into storm core.

An upper level trough of low pressure aloft was situated over the Intermountain West on April 27th. East of this feature, a warm front lifted into western Nebraska and became the focal point for thunderstorm development during the late afternoon hours. Initial thunderstorms developed over western Garden County and tracked northeast into abundant low level moisture, strong low level shear and increased instability where they quickly became severe. Hail up to 3 inches in diameter and eleven tornadoes occurred with the severe storms which continued into the mid evening hours. Activity finally weakened over northern Cherry County by late evening. A couple of tornadoes were rated EF2 with winds estimated up to 132 MPH.

Ground truth and sentinel data confirmed track. No damage indicators were available.

Brief touchdown over open rangeland. No damage was found.

Location based off photographic evidence. No damage indicators were found.

44 minutes of warning. NWS LBF issued a tornado warning for this county at 00:28 UTC, 44 minutes before the tornado touched down, in force until 01:15 UTC.

The county was under a tornado watch, issued at 21:56 UTC and running to 07:00 UTC.

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a Slight Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 00:59 UTC.

SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.

The radiosonde launches on either side of the tornado, from the nearest station that was launching then, drawn and analyzed the way Storm Lab does: the same diagram, the same parcel and shear definitions SPC's mesoanalysis uses.

The North Platte radar (KLNX), 85 km away, was scanning. The volume nearest the touchdown began at 01:09 UTC.

12 more were confirmed in the United States that day.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
