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 Jun 26, 2:38 PM CDT, 2 hours 3 minutes earlier.

Area forecast discussion, Jun 26, 2:38 PM CDT, 2 hours 3 minutes before

Area Forecast Discussion
National Weather Service Norman OK
238 PM CDT SUN JUN 26 2016

.DISCUSSION...
Daily convection will be main concern with some severe weather
and potential flooding the main impacts moving forward.

Next couple of days weak sfc boundary(s), outflow boundaries
and weak upper support will be sufficient for scattered
convection. Best chance today will be near low level boundary
across northern Oklahoma. A secondary area could be in southwest
OK and north TX as upper low cont to spin across west Texas.

This weak sfc boundary still appears to be present on Monday, a
bit farther south, and will once again act as a focus for
convective development throughout the day. Current atmosphere is
one with plenty of instability but very little, if any shear. So
storms will be slow-moving and efficient rain producers. So heavy
rainfall and wind will be main concerns with a secondary hail
threat.

As we move forward through the work week, we see upper ridge
shift back westward and northwest flow develop across the
Southern Plains. This will likely lead to nearly daily chances
for storms across the area. Although some severe risk will be
present, main concern may turn into a water issue, in the form of
flooding. Still a bit early to determine exactly where the
greatest threat may end up occurring. However, currently would
appear northeast half of Oklahoma would be most likely area to see
multiple rounds of heavy rainfall.
