530 PM CST Mon Dec 11 2017

Forecast is based on request time of 1800 CST on December 11.

National Weather Service.

...RED FLAG WARNING IN EFFECT UNTIL 6 PM CST THIS EVENING...

.DISCUSSION...

Red Flag conditions will continue through the late afternoon generally
along and south of the Missouri River.  A cold front has moved through
the area and this will cause temperatures to fall and relative humidity
to rise, ending the red flag conditions by early evening.  Strong
northwest wind will continue this evening...but should slowly diminish
overnight and into Tuesday.

However, elevated fire danger is possible again on Tuesday due to relative
humidity falling below 30 percent and sustained northwest wind in excess
of 12 mph as well as dry fuels. The wind will turn back to the west and
then southwest Tuesday evening into the overnight hours.  Another clipper
system will move across the Midwest on Wednesday with another round of
strong wind and low relative humidity possible on Wednesday afternoon.
