This Outlook is for Northwest and West Central Arkansas as well as
much of Eastern Oklahoma.

.DAY ONE...Through Tonight.

TORNADO.
	RISK...Limited.
	AREA...Southeast Oklahoma into western Arkansas.
	ONSET...Late afternoon or early evening.

SEVERE THUNDERSTORM.
	RISK...Elevated.
	AREA...Much of eastern Oklahoma and western Arkansas,
  	ONSET...Ongoing.

DISCUSSION...
Isolated to scattered thunderstorms are developing along a cold
front that is currently moving through northeast Oklahoma late this
afternoon. A few storms along the front may become severe into the
evening, especially across southeast Oklahoma and west central
Arkansas where the environment is more supportive of severe weather.
The strongest storms will be capable of producing all hazards,
including large to significant hail in excess of two inches in
diameter. A low tornado threat will exist as well. The severe
weather risk will end with the passage of the cold front. The front
is expected to exit the area around, or a little after midnight.

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

.DAYS TWO THROUGH SEVEN...Saturday through Thursday.
SATURDAY...Severe Thunderstorm Potential...High Wind Potential.
SUNDAY...Thunderstorm Potential...High Wind Potential.
MONDAY...No Hazards.
TUESDAY THROUGH THURSDAY...Thunderstorm Potential.

EXTENDED DISCUSSION...
Strong storm system will bring storm chances back to the area on
Saturday as storms could develop along a dryline in central
Oklahoma and spread eastward into the eastern Oklahoma during the
evening hours. All severe hazards will be possible, including
large to very large hail and tornadoes. Storms will likely be
isolated to widely scattered as a capping inversion limits
convection along the boundary during the afternoon before the
arrival of stronger forcing. A couple of quiet days are expected
for the remainder of the holiday weekend. Nightly thunderstorm
chances will return by mid week as northwest flow aloft sets up
and chances increase for storm complexes moving into the region
overnight.
