A severe weather and flash flood episode occurred across central and southern portions of the WFO Norman Forecast Area from the evening of the 19th into the early morning hours of the 20th. A slow-moving upper system continued to approach the area on the 19th. This, along with strong/moist low-level ascent atop a quasi-stationary boundary, helped initiate widespread thunderstorms across the region mentioned above. Strong wind shear and instability, especially along and ahead of the surface boundary, promoted organized thunderstorms, producing hail, wind and tornadoes. A few strong tornadoes also occurred (near Courtney in Love County and Little City in Marshall County). This episode also observed the first fatal weak (F/EF0-1) tornado since 1988 across the WFO Norman Forecast Area. Flash flooding also became a concern by the late evening of the 19th, with two flood-related fatalities occurring in the city of Moore, as multiple vehicles were swept off of Eastern Avenue into a nearby creek.

A tornado moved northeast across southwestern Marshall County, forming near the Red River and passed west of Kingston before dissipating south of Madill. A few homes suffered roof damage along the path, and many trees and power poles were damaged.

A barn was damaged along State Highway 199 east of Madill. A home suffered significant damage and an outbuilding was destroyed along Four Corners Road.

3 minutes of warning. NWS OUN issued a tornado warning for this county at 03:31 UTC, 3 minutes before the tornado touched down, in force until 04:00 UTC.

The county was under a tornado watch, issued at 23:48 UTC and running to 04:34 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 Enhanced Risk, with a 0.10 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 01:04 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 Norman radar (KTLX), 155 km away, was scanning. The volume nearest the touchdown began at 03:33 UTC.

27 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.
