What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Norman, OK wrote its last area forecast discussion before this severe thunderstorm warning went out at May 25, 3:57 PM CDT, 2 hours 28 minutes earlier.

Area forecast discussion, May 25, 3:57 PM CDT, 2 hours 28 minutes before
Area Forecast Discussion
National Weather Service Norman OK
357 PM CDT Fri May 25 2018

.DISCUSSION...
For late this afternoon/evening, isolated to scattered strong to
severe thunderstorms are expected to develop across the eastern
Texas panhandle. These thunderstorms would move east-southeastward
into southwest Oklahoma and adjacent parts of north Texas.

Steep mid-level lapses, >30 knots effective bulk shear, and large
CAPE in the hail-growth zone would be favorable for large hail.
Localized damaging wind gusts are also possible--especially if
enough storms develop for a complex to develop. Farther east,
isolated to scattered storms may continue across east-central
Oklahoma, but the risk of severe weather is lower.

For Sunday through Wednesday, northwest/northern Oklahoma will
maintain a low to moderate chance of showers and thunderstorms
for the possibility of any remnant High Plains convection and/or
influence from shortwave troughs forecast to eject into the
Central Plains. This area will be on the northern periphery of
the mid-level ridge. There is an outside chance one of these
complexes could affect areas farther to the south (such as central
Oklahoma) the middle of next week as a higher-amplitude shortwave
trough ejects into the Plains. Otherwise, most locations should
remain hot and dry.

Beyond Tuesday, both the 25/12Z GFS and ECMWF still indicate that
a hot pattern will develop across the Southern Plains; however,
the latest guidance is less amplified with the mid-level trough
(with a lower magnitude). Even so, near record temperatures are
still expected toward the end of next week.
