...SEVERE WEATHER POTENTIAL INCREASES AGAIN LATE TONIGHT...

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

.DAY ONE...This Afternoon and Tonight.

SEVERE THUNDERSTORM.
	RISK...Elevated.
	AREA...Eastern Oklahoma and Western Arkansas.
	ONSET...Ongoing...Increasing After Midnight.

FLASH FLOOD.
	RISK...Elevated.
	AREA...Eastern Oklahoma.
	ONSET...Ongoing.

HEAVY RAIN.
	RISK...Elevated.
	AREA...Northeast Oklahoma.
	ONSET...Late Tonight.

DISCUSSION...
Another thunderstorm complex is expected to develop to the west
this evening and move eastward into portions of eastern Oklahoma
and western Arkansas after midnight. Damaging winds from 60 to 70
mph will be the primary severe weather threat with this line of
storms, although locally heavy rainfall is likely as well. Isolated
flash flooding could become a concern in areas that saw a lot of
rainfall earlier this morning.

During the afternoon hours, isolated to scattered thunderstorms
may develop and move across mainly parts of northeast and east
central Oklahoma, posing a limited severe weather threat prior
to the larger threat tonight.

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

.DAYS TWO THROUGH SEVEN...Monday through Saturday.
MONDAY AND TUESDAY...Thunderstorm Potential.
WEDNESDAY...Dangerous Heat Potential.
THURSDAY THROUGH SATURDAY...No Hazards.

EXTENDED DISCUSSION...
Chances for thunderstorms will largely remain across northeast
Oklahoma and northwest Arkansas during the early part of this week
as an upper level system moves across the Northern Plains. Upper
level ridging will begin to build across the Southern Plains and
will become the dominant weather feature from mid week on.
