...SEVERE WEATHER AND HEAVY RAIN POTENTIAL INCREASES TONIGHT INTO TUESDAY...

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...Far Southeast Oklahoma.
	ONSET...This Evening.

SEVERE THUNDERSTORM.
	RISK...Elevated.
	AREA...Eastern Oklahoma and Northwest Arkansas.
	ONSET...This Evening.

FLASH FLOOD.
	RISK...Limited.
	AREA...Southeast Oklahoma.
	ONSET...This Evening.

HEAVY RAIN.
	RISK...Limited.
	AREA...Southeast Oklahoma.
	ONSET...This Evening.

DISCUSSION...
Thunderstorms developing across West and Northwest Texas this
evening will spread east and expand in coverage and intensity
reaching southeast Oklahoma before midnight. Additional storms are
expected across northeast Texas which also will spread north into
southeast Oklahoma late this evening. Wind shear and instability
will be sufficient for some storms to become strong to severe.
Large hail near tennis ball size and damaging wind gusts to 70
mph will be the main threats, though a tornado warning or two will
be possible as low level winds become more favorable with time.
Multiple rounds of storms moving across the same area will lead to
locally heavy rainfall, especially far southeast Oklahoma where a
flash flood threat will be present overnight.

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

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday.
TUESDAY...Thunderstorm Potential.
WEDNESDAY...Thunderstorm Potential...High Wind Potential...Heavy Rain Potential.
THURSDAY...Very High Fire Weather Potential...High Wind Potential.
FRIDAY...No Hazards.
SATURDAY...Very High Fire Weather Potential...High Wind Potential.
SUNDAY...High Wind Potential.

EXTENDED DISCUSSION...
An active weather pattern will set up through mid-week, with
numerous rounds of showers and thunderstorms likely across the
area as a slow moving storm system crosses the Southern Plains.
Severe weather concerns will diminish across the region by
Wednesday as instability becomes rather limited, but a few strong
to marginally severe storms will be possible until then, mainly
across southeast Oklahoma. Heavy rainfall will also become a
factor as showers and storms are slow to exit the region through
mid-week. Windy conditions will return over the weekend as
temperatures warm back into the 80s ahead of the next storm system
resulting in an increased wildfire threat.
