What forecasters said that day

The local office's own words before this red flag 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 red flag warning went out at Apr 10, 10:49 PM CDT, 5 hours 13 minutes earlier.

Area forecast discussion, Apr 10, 10:49 PM CDT, 5 hours 13 minutes before
Area Forecast Discussion
National Weather Service Norman OK
1049 PM CDT Tue Apr 10 2018

.DISCUSSION...
The 06Z aviation discussion follows....

&&

.AVIATION...
Winds will be the main feature of this TAF period. Southerly
surface winds will generally increase through the period,
particularly Wednesday morning. A low-level jet is expected to
form overnight, resulting in substantial low-level wind shear at
all sites toward sunrise. As daytime vertical mixing gets underway
by mid-morning, the LLWS will diminish, but surface winds and
gusts will increase. Winds will continue into the night Wednesday
night, and it is possible that LLWS will again be significant
early Thursday.

.PREV DISCUSSION... /issued 915 PM CDT Tue Apr 10 2018/

DISCUSSION...
Late evening temperature trends were adjusted slightly to slow the
cooling. Still, overnight low temperatures appear on track for a
mild night. No other changes to the forecast are anticipated this
evening.
