This hazardous weather outlook is for portions of northern...
western...central...and southern Oklahoma...and western north
Texas.

.DAY ONE...This Afternoon and Tonight...

.Thunderstorms...
There is Slight Risk of severe thunderstorms across portions of
northern and central Oklahoma and a Marginal Risk for much of the
rest of the area.

Location...
The Slight Risk area is northeast of a line from near Alva to
Hobart to Lawton to Seminole. A Marginal Risk surrounds the Slight
Risk and encompasses all but far northwest Oklahoma.

Timing...
The most likely time for severe weather will be from 3 PM to 10 PM.

Impacts...
Damaging winds up to 70 mph. Mainly quarter to half dollar size
hail but possibly as large as golf balls. Very heavy rain.

Discussion...
Thunderstorms will increase by mid afternoon across portions of
south-central and southeast Oklahoma. A few of these storms could
become severe with damaging wind gusts the primary threat.

A more substantial severe weather threat could develop later this
afternoon along a cold front moving through the area.
Thunderstorms with large hail and damaging winds could impact
north central Oklahoma first and then develop southwestward into
southwest Oklahoma. By evening, a line of thunderstorms could
form and move across much of central Oklahoma.

The potential for severe storms is expected to diminish late this
evening and overnight but thunderstorms will remain possible
across portions of the area through early Thursday. Heavy rain and
cloud to ground lightning would be the main impacts with these
storms.

.Heavy Rainfall/Flooding...
A very moist environment will support locally heavy rainfall
amounts and the potential for flooding or flash flooding. Portions
of the area have experienced heavy rainfall amounts already
causing the ground to be saturated. Additional heavy rainfall on
these saturated grounds could lead to flooding.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday...

.Thunderstorms...
Thunderstorms will be possible each day through Tuesday. Strong
to severe storms will be possible across western Oklahoma and
portions of western north Texas Thursday evening. Large hail and
damaging wind gusts will be the main concerns along with
torrential rainfall.

SEVERE THUNDERSTORM.
RISK...Elevated.
AREA...Eastern Oklahoma and Northwest Arkansas.
ONSET...Late Afternoon.

FLASH FLOOD.

ONSET...Ongoing.

SIGNIFICANT WINDS.
RISK...Limited.
AREA...Northeast Oklahoma.
ONSET...Ongoing.

DISCUSSION...
Scattered showers and thunderstorms will continue to lift
northeast across Eastern Oklahoma and Northwest Arkansas this
afternoon. Instability and wind shear values over the region will
allow for limited severe weather potentials with locally damaging
winds and hail being the main threats. Additional thunderstorm
chances become likely late this afternoon...evening and into
overnight hours tonight across Eastern Oklahoma and Northwest
Arkansas as storms are forecast to develop along a cold front
entering the region.

Instability interacting with the front will help to increase
severe potentials during the evening hours with a limited
potential remaining after midnight tonight. Damaging winds...large
hail and also a limited tornado potential will be possible
through the evening hours...with conditions becoming more of a
damaging wind threat after midnight tonight. Also...with
widespread moisture across the region...periods of heavy rainfall
will be possible which could create flash flooding conditions
especially over locations that have already received recent heavy
rains.

Across locations that remain dry through this afternoon...heat
index values in the upper 90s to near 105 degrees will be
possible. These conditions will decrease this evening with the
approaching cold front.


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

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday.
THURSDAY...Thunderstorm Potential.
FRIDAY...Thunderstorm Potential...Heavy Rain Potential.
SATURDAY THROUGH MONDAY...Thunderstorm Potential...Dangerous Heat
  Potential.
TUESDAY...Thunderstorm Potential.

EXTENDED DISCUSSION...
Thunderstorm chances will remain in the forecast Thursday across
Southeast Oklahoma and Northwest Arkansas as the cold front makes
its way through the region. A limited severe potential could be
possible over far Southeast Oklahoma ahead of the front.
Additional thunderstorm chances return Friday as an upper level
low pressure system moves across the Plains. Periods of heavy
rainfall will again be possible Friday with this next system.

A more typical August weather pattern looks to set up over the
weekend and into the start of next week. This will allow for warm
and humid conditions along with small daytime thunderstorm
chances to be possible across Eastern Oklahoma and Northwest
Arkansas this weekend into early next week.

This Hazardous Weather Outlook is for portions of the Missouri
Ozarks and extreme southeast Kansas.

.DAY ONE...This Afternoon and Tonight.

Weather hazards expected...

  Elevated Hail risk.
  Elevated Thunderstorm wind damage risk.
  Elevated Flooding risk.
  Significant Lightning risk.
  Limited Excessive heat risk.

DISCUSSION...

Afternoon heat indices will top out in the middle to upper 90s,
mainly across western Missouri and southeastern Kansas.

Scattered to numerous showers and thunderstorms will develop from
west to east across the outlook area this afternoon. Additional
thunderstorms can then be expected tonight as a cold front moves
southeast through the region.

A few severe thunderstorms will be possible this afternoon and
tonight, mainly to the west and north of a Gainesville to Salem
line. Large hail and damaging winds will be possible with the
strongest storms.

Torrential rainfall can also be expected from these storms due to
high moisture content in the atmosphere. Flash flooding will
therefore be possible in areas where multiple storms move over
the same areas. The highest risk for flash flooding will be across
southeastern Kansas and western Missouri.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday.

Periodic showers and thunderstorms will occur through the
upcoming week and into the weekend.

Heat index values will be the 90s each day into the weekend and
as high as 100 by early next week.

.SPOTTER INFORMATION STATEMENT...

Spotter activation may be needed later this afternoon and tonight
mainly to the west and north of a Gainesville to Salem line.
