.PREV DISCUSSION... /Issued 255 AM CDT Sat May 20 2017/

DISCUSSION...
Showers and thunderstorms beginning to wind down across eastern
Oklahoma early this morning as the responsible upper level low
moves out of the Rockies and into the Plains. Showers and thunderstorms
will linger through the morning hours across southeast Oklahoma and
western Arkansas. Will trim some of the Flash Flood Watch across northeast
Oklahoma with the issuance of this zone package. Will let the remainder of
the Watch run through 7 am.

High pressure is expected to prevail on Sunday and will result in a chilly
start to the day with lows ranging from the mid 40s to mid 50s. The next
chance of showers and thunderstorms will come Monday into Tuesday as a series
of upper level shortwaves in the developing northwesterly flow aloft affect
the region.

Have kept the remainder of the forecast dry as the northwesterly flow slowly
breaks down and the flow becomes more zonal over the region by the end of
the week.
