1. EF065 to 85 mph

   Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.

2. EF186 to 110 mphthis tornado

   Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.

3. EF2111 to 135 mph

   Considerable damage. Roofs torn off well-built houses, frame homes shifted on their foundations, mobile homes destroyed, large trees snapped or uprooted, cars lifted off the ground.

4. EF3136 to 165 mph

   Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.

5. EF4166 to 200 mph

   Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.

6. EF5over 200 mph

   Incredible damage. Strong frame houses swept off their foundations, car-sized missiles thrown more than 100 meters, steel-reinforced concrete badly damaged, high-rise buildings deformed.

7. Unrated

   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.

26 damage points were recorded along this path by NWS MPX, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 95 mph.

• Some trees uprooted or damaged.
• Small outbuilding completely destroyed and debris spread north northwest. Door was open and facing south. Truck and trailer overturned on highway 28. Home undamaged. Pine trees facing northwest on the west side of the property.
• Convergent uprooted tree damage. Several road signs twisted. Very little damage to church building.
• Irrigation systems overturned. Look up new DI.

A strong synoptic cyclone swinging into the Northern Plains set the stage for a late Spring severe weather outbreak on May 30th. Discrete and semi-discrete supercells developed during the afternoon ahead of an arcing cold front and a nearby surface low. These storms quickly traveled northeast while gradually growing upscale into bowing line segments as storms merged together and new cells formed. During this time, hail and tornadoes occurred; the strongest being an EF2 through Forada, MN. The bowing line segments became dominant and a wind event unfolded.||Strong and broad synoptic lift, little capping, and questionable mid-level shear likely allowed for upscale growth. This caused storm interactions and competing updrafts which may have limited mesocyclone longevity and strength. While property was damaged, no lives were lost on the last day of a holiday weekend when many people were outdoors camping or doing other recreational activities.

This tornado developed in Swift County, about 5 miles southwest of Danvers, and tracked north until an outflow boundary caught up with it, then the tornado tracked northeast to 7 miles northwest of Clontarf. It then moved through the southeast corner of Stevens County and into Pope County, where it dissipated. Several wooden poles with electrical transmission lines were snapped. Irrigation systems were overturned, trees were damaged, and some structural damage to homes and farm outbuildings also resulted. Maximum winds were estimated at 100 mph.

Tornado spun up just west of Lake Emily and tracked northeast. Some trees were snapped and farm outbuildings were damaged. Maximum winds were estimated at 95 mph. This tornado was filmed on video.

A tornado developed about 4 miles west of Starbuck and tracked northeast. A small outbuilding was completely destroyed and debris was spread north northwest. A truck and trailer were overturned on Highway 28. Maximum winds were estimated at 90 mph.

A tornado originated on the east side of Lake Reno in Pope County. At first, it damaged about a dozen trees, but quickly became more intense and broke or uprooted several hundred trees before entering Douglas County. Maximum winds for the Pope County portion were estimated at 105 mph.

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down. One was issued for the county at another hour that day.

The county was under a tornado watch, issued at 19:37 UTC and running to 22:56 UTC.

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 Moderate Risk, with a 0.15 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 19:55 UTC.

36 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.
