The upper level trough responsible for severe weather across the area on the 14th continued to impact New Mexico through the 15th. Abundant moisture and instability associated with southeasterly upslope flow and strong upper level dynamics generated an extended period of severe weather across the eastern plains. Severe thunderstorms from late on the 14th persisted past midnight before diminishing before sunrise. A powerful storm that moved south of Melrose just after midnight produced one of the best radar signatures of a tornado forecasters have ever observed in eastern New Mexico. A nearby resident reported a loud roaring sound in the distance. A persistent storm with torrential rainfall amounts over four inches in eastern San Miguel County produced flash flooding along Atarque Creek through sunrise. Storms fired up quickly again by late morning and moved east across the plains. A funnel cloud was observed just after the noon hour near Vaughn. Another storm that moved east across Lincoln County dumped nickel to quarter size hail in the area around Tinnie, Picacho, and Dunken. A tornado and golf ball size hail was then spotted from this storm over rural ranch lands to the northeast of Dunken. Many other storms that impacted eastern New Mexico generated hail, torrential rainfall, and gusty winds throughout the afternoon.

A nearby resident reported a loud, distant roaring sound over the Melrose Bombing Range where radar indicated very intense rotation. A storm survey of this extremely remote location later revealed a 2000 pound mobile office trailer that was bolted and strapped down was lifted and moved eight to ten inches.

0 minutes of warning. NWS ABQ issued a tornado warning for this county at 06:07 UTC, 0 minutes before the tornado touched down, in force until 06:30 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 Marginal Risk. The outlook in force was issued at 06:00 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.

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.
