.DISCUSSION...
Organized thunderstorm complex continues to spread across far
eastern/northeastern Oklahoma toward northwest Arkansas this evening.
Although a weakening trend has been noted, activity likely to persist
as it moves through much of northwestern Arkansas next few hours.
Air mass remains moderately unstable ahead of the activity but
increasing CIN and outflow somewhat ahead of the convection will keep
any severe threat isolated. Adjusted grids to account for current
convective trends next few hours. Expect any redevelopment overnight
to be along/north of outflow boundary, which extends from central
Oklahoma through Pittsburg, Latimer, and Le Flore Counties, and will
eventually push into west central Arkansas.

Strong convection and very moist air mass over the area resulted in
some locally heavy rainfall across portions of northeastern Oklahoma
this evening. Additional development into some of those areas will
likely result in flooding, although this is expected to be isolated
should it occur.
