A couple long-tracked supercells moved across the northern two to three rows of counties during the predawn hours of the Memorial Day weekend. These storms triggered numerous tornadoes, some of which strong and long-lived, in addition to widespread straight-line wind damage.

The Boone-Marion County tornado continued into Marion County from Boone County, paralleling just south of US Highway 62, near Pyatt.|Marion County EM reported three fatalities from this tornado.|Extensive tree damage was observed across several county roads,|and a few mobile homes were tossed and destroyed on Marion County|Road 4010. After crossing Marion County Road 4010, the tornado|path width increased to its widest point, and likely maintained a|maximum path width of around 2000 yards for a few miles, via|satellite imagery, as it moved through the Crooked Creek Valley.|Extensive tree damage was observed along and around Crooked|Creek, and moderate damage to the second level of a tin home was|found as well. The tornado kept moving northeast, snapping most|trees in its path as it crossed Crooked Creek multiple times and|eventually, Marion County Road 4006, where it moved over the Snow|Access Campground Area. The tornado then crossed US Highway|62 again near the small municipality of Snow, causing minor to|moderate damage to a few homes around the area. As the tornado|crossed US Highway 62, the path width began to decrease, and it|began moving more eastward. Mainly tree damage was observed to|the north of US Highway 62, and eventually it crossed State|Highway 125, and Marion County Road 3032, where more|extensive tree damage was observed, and another mobile home,|which was untethered, was lofted and completely destroyed. The|tornado continued to move east-northeast, causing mostly tree|damage, before eventually dissipating to the northwest of Summit.|This tornado tracked across two counties and was rated an EF3 with maximum estimated wind speeds|of up to 145 mph.

The Briarcliff Tornado continued in Baxter County from Marion County and|moved through a small residential area along the White River,|pulling siding and shingles off houses in addition to causing|significant tree damage. The tornado continued eastward, further|expanding in width, and reached a maximum width of up to 1 mile|wide, crossing mostly rural areas and causing significant tree|damage, passing across Wild Hog Mountain, and crossing Shipps|Ferry Road and Round Rock Trail. As it approached the Arkana and|Norfork Village area, the path width contracted slightly, and|large swaths of trees were found uprooted and snapped as it|crossed the White River briefly once again north of Hwy 341 at|Riverside Dr. The tornado continued northeast towards Briarcliff,|where mostly tree damage was observed to the west of Highway 5.|As the tornado crossed the highway, widespread tree damage became|prevalent, with most trees snapped at their trunks. A few|structures were severely damaged, including a home, and a metal|shop building. The tornado also impacted a local RV/trailer|camping park, where five fifth-wheel recreation trailers were|tossed and completely destroyed. One fatality was reported out of|this area as well. The tornado also moved over a 350 kV|transmission line that intersected Hwy 5, snapping several wooden|two-poled line towers, and bending two steel two-poled line|towers to the ground, indicative of EF2 wind speeds. After|crossing Hwy 5, the tornado moved into the Briarcliff residential|area, encountering significant topography. 17 injuries were|reported within the Briarcliff community. The tornado path width|expanded again, reaching a width of up to 1 mile wide for a short|duration as it moved through Briarcliff. Significant tree damage|was observed over a large portion of the roads in the area, and|via satellite imagery. A few homes sustained moderate damage,|likely exacerbated by debris and projectiles. The Briarcliff City|Hall building, which sat on top of a hill on Scenic Drive,|sustained significant structural damage, with most of the second|level of the building destroyed, indicative of EF3 wind speeds of|up to 140 mph. The tornado then continued to move northeast,|moving over several hills on the east side of Briarcliff. A two-|story home located off of the Shoal Creek tributary sustained|significant roof damage with most of the structure pulled off to|the wall plates, and all the surrounding trees to the east|uprooted from the road to the waterline. The tornado then crossed|the lake, and struck a few peninsulas, where more significant|tree damage was observed. After crossing Norfork Lake, the|tornado continued northeast on the north side of the lake, moving|over mostly rural areas, eventually crossing over the Holiday|Hills Resort Area on Baxter County Road 149. A few buildings|sustained minor roof damage, and a smaller cabin building had the|roof structure pulled off with a few exterior walls collapsed.|Most trees around the resort were uprooted as well. The tornado|then kept moving northeast into Fulton County.

The Sycamore Heights Tornado developed near the end of Fallen Timber Lane west of|Baxter County Road 69, moving east crossing this County Road|69 south of Maple Hollow Road. Several trees were either snapped|or uprooted along this section of the path, but some light|structural damage was noted as it crossed County Road 69, along|with blowing down a fence. As the tornado crossed Morton Creed,|it turned towards the north then crossed Unger Trail, causing|more tree damage and some minor structural damage. It was near|this area where this tornado came in very close proximity to an|adjacent, much larger tornado (Briarcliff Tornado) just to the|southeast near Arkansas Highway 5. This tornado started to move|just north of the southern tornado as it crossed Highway 5,|ripping a roof off a home consistent with EF-2 damage. Lifting|further north, the tornado cross over some neighborhoods east of|Arkansas Highway 5 in northwest portions of Briarcliff, causing|mainly tree damage and some minor structural damage. At this|point, the tornado began moving in a more northeast direction|towards Sycamore Heights, then eventually lifting in the Sycamore|Spring neighborhood. The damage along the rest of this track was|primarily uprooted or snapped trees. This additional tornado was|confirmed from satellite and high resolution areal imagery, also|showing a distinction from the much larger Briarcliff named|tornado just to the south. This tornado was rated an EF2 with|maximum estimated winds of 115 mph.

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 06:00 UTC.

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.
