...SEVERE THUNDERSTORM THREAT CONTINUES THIS EVENING AND EARLY SUNDAY MORNING...

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

.DAY ONE...Tonight.

TORNADO.
RISK...Limited.
AREA...South of Interstate 40.
ONSET...Early Evening.

SEVERE THUNDERSTORM.
RISK...Elevated.
AREA...South of Highway 412.
ONSET...Early Evening.

HEAVY RAIN.
RISK...Limited.
AREA...South of Interstate 40.
ONSET...Early Evening.

DISCUSSION...
An Elevated risk of severe thunderstorms exists this evening and
into early Sunday morning across much of eastern Oklahoma and
western Arkansas along and south of Highway 412. The strongest
storms are likely to develop late this afternoon near a
retreating outflow boundary across parts of western and central
Oklahoma, eventually moving into parts of southeast Oklahoma mid
to late evening. These storms could have the potential to produce
damaging winds to 70 mph, golf ball size hail, and isolated
tornadoes. Additional strong to severe thunderstorms may develop
farther north during the late evening and early Sunday morning
hours as the low level jet increases. Most of the activity should
be south and east of the forecast area by sunrise Sunday.

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

.DAYS TWO THROUGH SEVEN...Sunday through Friday.
SUNDAY...Severe Thunderstorm Potential...Heavy Rain Potential.
MONDAY AND TUESDAY...Thunderstorm Potential.
WEDNESDAY AND THURSDAY...Dangerous Heat Potential.
FRIDAY...No Hazards.

EXTENDED DISCUSSION...
An Elevated risk of severe thunderstorms will again develop
Sunday night mainly to the north of Interstate 44 in northeast
Oklahoma, with damaging winds being the primary threat. A
thunderstorm complex is expected to organize over western Kansas
and northwest Oklahoma Sunday afternoon and evening and will move
eastward Sunday night. Locally heavy rainfall is possible with
this complex in addition to the damaging wind threat. A chance of
thunderstorms will persist along the remnant outflow boundary or
front Monday and Monday night, primarily across northeast
Oklahoma.

Ridging aloft will strengthen over the region by the middle of
next week. The combination of the intensifying heat and humidity
will bring forecast afternoon heat index values to potentially
dangerous levels on Wednesday and Thursday, possibly extending
through the end of the work week.
