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

.DAY ONE...Today and Tonight.

SEVERE THUNDERSTORM.
    RISK...Elevated.
    AREA...Northeast Oklahoma and Northwest Arkansas.
    ONSET...After 7PM.

FLASH FLOOD.
RISK...Limited.
AREA...Northeast Oklahoma and Northwest Arkansas.

HEAVY RAIN.

AREA...Northeast Oklahoma and Northwest Arkansas.
ONSET...After 7PM.

SIGNIFICANT WINDS.
RISK...Limited.
AREA...Eastern Oklahoma and Western Arkansas.
ONSET...Mid Morning.

DISCUSSION...
Very strong southerly winds will develop by mid morning across
eastern Oklahoma and western Arkansas with wind gusts to 35 miles
an hour possible by late morning into early afternoon.

Late this afternoon, showers and thunderstorms are expected to
form across north central Oklahoma and southeast Kansas along and
ahead of a cold front. Wind fields at the surface and at upper
levels will be quite strong, with moderate instability developing
this afternoon. The atmosphere is expected to stay capped most of
the day, with storms moving into northeast Oklahoma after 7 PM.
Once storms form, they will likely quickly become strong or
severe, with the potential for large hail or severe wind gusts.
Storms will approach the Interstate 44 corridor by or just before
midnight and will not affect northwest Arkansas until after
midnight Wednesday. The line of storms will likely weaken through
the overnight hours, with locally heavy rain possible.

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

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY.
WEDNESDAY...Severe Thunderstorm Potential...High Wind Potential...Heavy Rain Potential.
THURSDAY...Thunderstorm Potential.
FRIDAY and SATURDAY...Severe Thunderstorm Potential...Heavy Rain
POTENTIAL.
SUNDAY and MONDAY...No Hazards.

EXTENDED DISCUSSION...
There will be storms ongoing early Wednesday morning, and
depending on the evolution of the squall line and cold front,
there may be a threat for additional severe storms Wednesday
across mainly western Arkansas and southeast Oklahoma.

The stormy pattern will continue with a more significant severe
and heavy rain threat on Friday and Saturday. With the approach of
an upper level storm system Friday afternoon, storms will develop
with the potential for large hail, damaging winds and a few
tornadoes. The severe potential will continue into Saturday, but
the main hazard may transition to heavy rain and flooding Saturday
into Sunday. At least 2 to 3 inches of rain is likely, with
localized higher amounts of 5 or 6 inches. This will definitely
cause some flash flooding and river flooding across portions of
the area this weekend.

EMERGENCY MANAGEMENT PLANNING STATEMENT...
The next few days will be active across eastern Oklahoma and
western Arkansas. Follow forecast updates to have the latest
information on the expected hazardous weather over the next few
days.
