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

.DAY ONE...Today and Tonight.
TORNADO.
	RISK...Limited.
	AREA...Eastern Oklahoma.
	ONSET...This Afternoon.

SEVERE THUNDERSTORM.
	RISK...Significant.
    AREA...Eastern Oklahoma and Northwest Arkansas.
    ONSET...This Afternoon.

	AREA AT GREATEST RISK...Northeast Oklahoma.

HEAVY RAIN AND FLASH FLOOD.
	RISK...Limited.
	AREA...Eastern Oklahoma and Northwest Arkansas.
	ONSET...This Afternoon.

DISCUSSION...
Severe thunderstorms will become possible again by this afternoon
across the region a a storm system begins to move out into the
Plains this afternoon. Scattered thunderstorm development is
possible along a dryline in western/central Oklahoma this
afternoon, with storms moving east northeast toward eastern
Oklahoma by this evening. Ample instability and shear present will
support supercells capable of all hazards with potentially high
impact hazards such as very large hail and tornadoes. Additional
severe thunderstorms could move out of north Texas later this
evening and overnight across portions of southeast Oklahoma.

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

.DAYS TWO THROUGH SEVEN...Monday through Saturday.
MONDAY...Severe Thunderstorm Potential...High Wind Potential...Heavy Rain Potential.
TUESDAY...Thunderstorm Potential...High Wind Potential.
WEDNESDAY...No Hazards.
THURSDAY AND FRIDAY...Thunderstorm Potential.
FRIDAY...Thunderstorm Potential.
SATURDAY...Thunderstorm Potential...Heavy Rain Potential.

EXTENDED DISCUSSION...
The threat for severe weather increases further on Monday.
Unstable air is forecast to overspread the entire area as a storm
system approaches from the west. The degree of forecast
instability and the pattern of the winds aloft suggest the
potential for very large hail, damaging winds, and a few tornadoes
on both Sunday and Monday. On Sunday, the greater risk is
expected to be more confined to parts of northeast Oklahoma. The
higher-end potential on Monday is forecast to be over most of
eastern Oklahoma and northwest and west-central Arkansas. Severe
thunderstorm chances continue into early Tuesday as the system
exits the area to the east during the day.

Low to medium thunderstorm chances, including a limited risk of
severe weather, are reintroduced late this week after a couple of
days of fair weather.

EMERGENCY MANAGEMENT PLANNING STATEMENT...
Emergency management and response agencies should be ready for 3 days
in a row of severe weather operations, and be ready to respond to
impacts.
