...SEVERE WEATHER AND HEAVY RAIN CONTINUES THROUGH TONIGHT...

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

.DAY ONE...This Evening and Tonight.

TORNADO.
	RISK...Limited.
	AREA...Northeast and East Central Oklahoma as well as Western
		    Arkansas.
	ONSET...Ongoing.

SEVERE THUNDERSTORM.
	RISK...Significant.
	AREA...Eastern Oklahoma and Western Arkansas.
	ONSET...Ongoing.

	AREA AT GREATEST RISK...Along and North of Interstate 40.

HEAVY RAIN AND FLASH FLOOD.
	RISK...Limited.
	AREA...Eastern Oklahoma and Western Arkansas.
	ONSET...Ongoing.

SIGNIFICANT WINDS.
	RISK...Limited.
	AREA...Eastern Oklahoma and Western Arkansas.
	ONSET...Ongoing.

DISCUSSION...
Thunderstorms will continue to develop across eastern Oklahoma and
northwest Arkansas this evening with the greater potential along
and north of Interstate 40. Storm development will continue to be
more scattered for the next hour or two, and then develop into
a complex later this evening before weakening late overnight.
The initial storms through mid evening will be capable of large
to very large hail, damaging winds, and isolated tornadoes. Then,
storms will transition to a damaging wind and quick spin-up
tornado threat for the late evening and early overnight hours. In
addition to severe potentials, a heavy rain threat will exist,
with minor flash flooding possible under any storms.

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

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

EXTENDED DISCUSSION...
Some early morning thunderstorms may linger over western Arkansas
Thursday morning before moving east. Isolated afternoon storms
could develop over portions of far eastern Oklahoma into western
Arkansas Thursday afternoon. If a storm develops, it would have
potential to become severe.

More thunderstorms are expected to develop across northern
Oklahoma Friday afternoon along a dryline, ahead of an upper
storm system and associated surface low pressure and cold front.
These storms will have a decent chance of becoming severe in an
unstable and strongly sheared environment, and would be capable of
producing higher-end severe weather. This includes very large
hail, locally damaging wind and tornadoes. Eventually, the cold
front will overtake the dryline and will force a band of storms
along it, with a damaging wind threat Friday night.
