DISCUSSION...

Multiple rounds of strong to severe storms are expected across
eastern Oklahoma and northwest Arkansas today and tonight. Large
hail to baseball size and damaging wind gusts to 70 mph are the
main threats. A limited tornado threat exists later today into
the evening down closer to the warm front across east central and
southeast Oklahoma as well as west central Arkansas. What may be
of more significance is the increasing and potentially life-
threatening flood threat as these multiple rounds of storms track
over the same areas.

Storms this morning across northeast Oklahoma and northwest
Arkansas will pose a severe wind and hail risk. Storms may
actually persist off and on thru the day across this region, with
an increasing flash flood risk with time.

Additional storm development is expected this afternoon across
east central and southeast Oklahoma closer to the front with the
activity expected to move into west central Arkansas by early
evening. This activity will have the potential to produce the
greatest severe threat, with very large hail, damaging winds and
isolated tornadoes possible. A flash flood threat will also
increase with time over this area.

The severe threat will decrease tonight as the storms exit the
region to the east. However, the flood threat will likely linger
through the weekend.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT... Activation
of the Regional Spotter Network Expected.

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY.
SUNDAY...Thunderstorm Potential...High Wind Potential.
MONDAY...High Wind Potential.
TUESDAY and WEDNESDAY...Thunderstorm Potential.
THURSDAY and FRIDAY...No Hazards.

EXTENDED DISCUSSION...

Thunderstorms will be exiting the region to the east Sunday
morning. Winds will increase as an area of low pressure
intensifies to our north and will become gusty at times.

Another storm system diving into the region from the northwest
will bring thunderstorm potential late Tuesday into Wednesday.
