This Hazardous Weather Outlook is for portions of southwest
Arkansas and southeast Oklahoma.

.DAY ONE...Today and Tonight...

Scattered showers and thunderstorms will increase especially late this
afternoon and early evening over Southeast Oklahoma and Western
Arkansas, along and just ahead of a slow moving cold front with
its associated upper level storm system entering Northwest Texas
and Western Oklahoma. There could be a period of slow moving
thunderstorms containing heavy rain that may cause flash flooding
across the area this evening, before these storms consolidate into
a line of strong to severe thunderstorms and quickly advance east
by mid to late evening. Widespread rainfall amounts of two to four
inches, with isolated higher amounts in excess of five inches,
will be possible this afternoon through tonight. In addition to
the heavy rain and flash flood threat, damaging winds, isolated
tornadoes, and large hail will be possible this evening, with
these threats diminishing from west to east late.

.DAYS TWO THROUGH SEVEN...Sunday through Friday...

Showers and thunderstorms will increase once again Wednesday ahead
of a cold front and associated upper level disturbance. However,
the threat for severe thunderstorms appear low at this time.

.SPOTTER INFORMATION STATEMENT...

Activation of emergency managers, spotter networks, and amateur
radio operators, will be needed late this afternoon through
tonight.

This Hazardous Weather Outlook is for portions of south central
Arkansas, southwest Arkansas, north central Louisiana, northwest
Louisiana, east Texas and northeast Texas.

.DAY ONE...Today and Tonight...

Isolated to widely scattered showers and thunderstorms will be
possible this afternoon across East Texas, North Louisiana, and
Southcentral Arkansas as an upper level disturbance ejects
northeast across the region ahead of a strong upper level storm
system that will enter Northern New Mexico. Should this
disturbance be able to overcome the capping inversion in place,
some of the storms that may develop will become severe, with large
hail and damaging winds the primary threats. Showers and
thunderstorms are expected to develop early this evening over
Western Arkansas, Southeast Oklahoma, and into Eastcentral Texas
along and ahead of a cold front, which will intensify as they
shift east across the region tonight. Some of these storms may
become severe, with damaging winds, isolated tornadoes, large
hail, and locally heavy rainfall possible. The severe weather
threat will gradually diminish from west to east across East Texas
late tonight as these storms move into Southwest Arkansas and
North Louisiana.

.DAYS TWO THROUGH SEVEN...Sunday through Friday...

Strong to possibly severe thunderstorms will be exiting the
eastern sections of Northcentral Louisiana around daybreak Sunday
with the passage of a cold front, although the threat for heavy
rainfall will persist through mid morning before rain rates taper
as drier air spills eastward. Look for the showers and embedded
thunderstorms to diminish from west to east through mid afternoon
Sunday. Showers and thunderstorms will increase once again Wednesday
ahead of a cold front and associated upper level disturbance.
Depending on the extent of surface heating and resultant
instability, there is a potential for at least isolated severe
thunderstorms across the region Wednesday, before cooler and drier
air filters southeast behind the cold frontal passage Wednesday
night.

.SPOTTER INFORMATION STATEMENT...

Activation of emergency managers, spotter networks, and amateur
radio operators, will be needed tonight.

...SIGNIFICANT FLOOD AND SEVERE RISK THRU THE WEEKEND...

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...East Central and Southeast Oklahoma and West Central Arkansas.
ONSET...This afternoon.

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

AREA AT GREATEST RISK...East Central and Southeast Oklahoma and West Central Oklahoma.

FLASH FLOOD.
RISK...Significant.
AREA...Along and southeast of I-44.
ONSET...This morning.

HEAVY RAIN.
RISK...Significant.
AREA...Along and southeast of I-44.
ONSET...This morning.

AREA AT GREATEST RISK...Between I-44 and I-40.

DISCUSSION...

Multiple rounds of strong to severe storms are expected across
eastern Oklahoma and northwest Arkansas today and tonight. Large
hail to baseball size and damaging wind gusts to 70 mph are the
main threats. A limited tornado threat exists later today into
the evening down closer to the warm front across east central and
southeast Oklahoma as well as west central Arkansas. What may be
of more significance is the increasing and potentially life-
threatening flood threat as these multiple rounds of storms track
over the same areas.

Storms this morning across northeast Oklahoma and northwest
Arkansas will pose a severe wind and hail risk. Storms may
actually persist off and on thru the day across this region, with
an increasing flash flood risk with time.

Additional storm development is expected this afternoon across
east central and southeast Oklahoma closer to the front with the
activity expected to move into west central Arkansas by early
evening. This activity will have the potential to produce the
greatest severe threat, with very large hail, damaging winds and
isolated tornadoes possible. A flash flood threat will also
increase with time over this area.

The severe threat will decrease tonight as the storms exit the
region to the east. However, the flood threat will likely linger
through the weekend.

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

.DAYS TWO THROUGH SEVEN...SUNDAY THROUGH FRIDAY.
SUNDAY...Thunderstorm Potential...High Wind Potential.
MONDAY...High Wind Potential.
TUESDAY and WEDNESDAY...Thunderstorm Potential.
THURSDAY and FRIDAY...No Hazards.

EXTENDED DISCUSSION...

Thunderstorms will be exiting the region to the east Sunday
morning. Winds will increase as an area of low pressure
intensifies to our north and will become gusty at times.

Another storm system diving into the region from the northwest
will bring thunderstorm potential late Tuesday into Wednesday.
