What forecasters said that day

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

Area forecast discussion, Jun 1, 3:28 PM CDT, 2 hours 38 minutes before
Area Forecast Discussion
National Weather Service Tulsa OK
328 PM CDT Thu Jun 1 2017

.DISCUSSION...
Weak trough axis noted across southern Oklahoma has resulted in
scattered showers and thunderstorms across southeast
Oklahoma...with less coverage observed across northwest Arkansas.
Short term local guidance indicates most activity will remain
diurnal in nature...so will follow accordingly by keeping low pops
in for the first period. Larger scale upper trough in conjunction
with an uncapped environment will keep the area unsettled through
the weekend. The aforementioned upper feature will be slow to
advance east...but expect an uptick in areal coverage by the first
half of the weekend as it moves into the southern plains. By
Sunday...as the trough axis settles further south and east a weak
boundary will move into at least parts of the area. Rain/thunder
chances to remain highest across southeast Oklahoma...with lower
pops further north and west. Early next week...an upper system
across the northeast CONUS and weak ridging to the west will keep
the forecast area on the cusp of weak meridional N-S flow. Not
really a favorable pattern for MCS development. That...and drier
air advecting into the area from the north-northeast...will opt
to keep the last few periods of the forecast cycle dry for now.
As for temperatures...ample cloud cover and forecasted rain
chances will keep temperatures down...thus the cooler guidance
temperatures have generally been followed.
