What forecasters said that day

The local office's own words before this flash flood 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 flash flood warning went out at Jun 1, 3:39 PM CDT, 1 hour 53 minutes earlier.

Area forecast discussion, Jun 1, 3:39 PM CDT, 1 hour 53 minutes before
Area Forecast Discussion
National Weather Service Norman OK
339 PM CDT Sat Jun 1 2019

.DISCUSSION...
A small cluster of storms that moved across central Oklahoma this
afternoon, will continue to move southeast. Gusty winds and heavy
rainfall can be expected. An outflow boundary continues to push
southward across southwest Oklahoma and eastern parts of the Texas
Panhandle. Scattered thunderstorms are developing along and just
north of this boundary. Depending on afternoon development, most
of the storms across western north Texas and western Oklahoma
should decrease in intensity this evening. Better storm
organization may occur over the High Plains. Storms should
organize and move southeast and impact parts of western Oklahoma
and western north Texas late this evening and overnight. Storm
development along a cold front in southern Kansas appears more
questionable.

The forecast area will generally remain on the eastern side of a
shortwave ridge through early next week. Therefore, additional
thunderstorm complexes may impact the area, generally during the
late evening and overnight hours. Locally heavy rainfall and
perhaps some flooding will be possible.

A trough will approach the area around Wednesday/Thursday of next
week. Widespread showers and storms with heavy rainfall will be
possible during this period.
