EXTENDED DISCUSSION...

A low pressure system will move into northeast Oklahoma late
Saturday afternoon. The atmosphere will become extremely unstable
ahead of the surface low with severe storms rapidly developing
across northeast Oklahoma by late afternoon or early evening.
Supercells will initially be possible with hail to the size of
baseballs and destructive winds to 80 mph. A few strong tornadoes
will also be possible.

Thunderstorms will become more linear in nature Saturday night
with one or more convective bands sweeping southeast across the
remainder of eastern Oklahoma and northwest Arkansas during the
overnight hours. Damaging winds will become the main threat
although a limited tornado threat could persist. In addition,
heavy rainfall will be likely in the stronger storms and localized
flash flooding could become a significant concern.

Storms will begin to shift southeast of the region Sunday morning
with dry conditions on Monday. Low thunderstorm chances return for
the remainder of the week.

EMERGENCY MANAGEMENT PLANNING STATEMENT...

Severe weather watches and warnings should be anticipated late
Saturday afternoon into Saturday night. The holiday weekend will
provide numerous outdoor exposures which will further increase the
potential for a rapid safety response. Closely monitor the latest
forecasts and updates as overall threats continue to be refined.
