.PREV DISCUSSION... /Issued 251 PM CDT Sun Aug 13 2017/

DISCUSSION...
Significant areal flooding is ongoing across portions of Sequoyah
county in far eastern OK...where around 6 inches of rain fell
since midnight. Any additional rain fall through tonight will
remain spotty or stay south of the area...so should see flood
waters receding through the night.

The synoptic boundary was located near the Red River this
afternoon...and expect this to lift north as a warm front on
Monday as another mid-level wave approaches. This feature will be
the focus for additional precipitation...mainly south of I-40
tomorrow then transitioning to far northeast OK/northwest AR
Monday night/Tuesday.

The upper pattern will remain quite active through mid to late
week...with the forecast area staying along the southern edge of
the mid-level westerly flow. Best rain chances will generally be
across northeast OK into northwest AR as a weak surface boundary
remains nearby...and models continue to suggest a potential MCS
for Thursday night into Friday.

Mid-level heights are forecast to rise going into the
weekend...with the better rain chances likely shifting to our
north.
