...WIDESPREAD SIGNIFICANT FLASH FLOODING EXPECTED OVER PORTIONS OF
E CENTRAL OKLAHOMA AND NW ARKANSAS FRI NIGHT THROUGH SAT NIGHT...

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

.DAY ONE...Today and Tonight.

THUNDERSTORMS WITH DANGEROUS LIGHTNING.
RISK...Elevated.
    AREA...Northeast Oklahoma and Northwest Arkansas.
    ONSET...Tonight.

POOR VISIBILITY.
    RISK...Limited.
    AREA...Far Northeast Oklahoma and Northwest Arkansas.
    ONSET...Ongoing.

SIGNIFICANT WINDS.
RISK...Limited.
AREA...Eastern Oklahoma and Western Arkansas.
    ONSET...Mid morning through afternoon.


DISCUSSION...
Areas of dense fog are ongoing this morning across far northeast
Oklahoma and northwest Arkansas after yesterday`s heavy rains.
Visibility may drop quickly over short distances, occasionally
falling to below 1/2 mile. Conditions will improve rapidly after
sunrise.

Winds will increase this afternoon ahead of the next low pressure
system. Expect some wind gusts from 15 to 20 miles per hour this
afternoon. Thunderstorms are possible beginning late this
afternoon and evening across northeast Oklahoma, with a greater
chance after dark across northeast Oklahoma into northwest
Arkansas. Widespread severe weather is not expected with this
system tonight.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
Spotter Activation Not Expected.

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

EXTENDED DISCUSSION...
A Flash Flood is in effect for portions of northeast Oklahoma and
western Arkansas beginning Friday night. An upper level storm
system will approach the Four Corners region late Friday,
bringing both the potential for severe weather and heavy rain. At
the surface, a warm front will lift north across central and
eastern Oklahoma on Friday afternoon. This will serve as a focus
for late afternoon showers and thunderstorms. Given the favorable
shear and instability that will be in place south of the warm
front Friday afternoon, scattered severe thunderstorms are
expected with the potential for large hail and damaging winds.
Tornadoes are possible as well, particularly with any discrete
storms which form early in the evolution of the event.

Eventually, storms are forecast to develop into a large complex.
Strong southerly low level flow will transport abundant moisture
over the surface boundary across Oklahoma resulting in storms
forming over and over across the same areas. This setup is
expected to be maintained over portions of eastern Oklahoma and
western Arkansas for a significant time beginning Friday night and
ending by Sunday morning. Widespread storm total rain amounts of
4 to 8 inches appear likely with isolated higher amounts. This
will result in a major flash flooding and river flooding event
through the weekend.

EMERGENCY MANAGEMENT PLANNING STATEMENT...
Continue to follow the latest updates regarding the expected
hazardous weather that will affect much of the area by this
weekend.

...FLASH FLOOD WATCH IN EFFECT FROM FRIDAY EVENING THROUGH SUNDAY
MORNING...

The National Weather Service in Tulsa has issued a

* Flash Flood Watch for portions of Arkansas and Oklahoma...
  including the following counties...in Arkansas...Benton...
  Carroll...Crawford...Franklin...Madison...Sebastian and
  Washington AR. in Oklahoma...Adair...Cherokee...Craig...
  Creek...Delaware...Haskell...Latimer...Le Flore...Mayes...
  McIntosh...Muskogee...Okfuskee...Okmulgee...Ottawa...
  Pittsburg...Pushmataha...Rogers...Sequoyah...Tulsa and
  Wagoner.

* From Friday evening through Sunday morning

* A potent upper level storm system will move into the area Friday
  with strong to severe thunderstorms developing by early evening
  across portions of eastern Oklahoma and northwest Arkansas.
  Thunderstorms will continue Friday night through Saturday evening
  with locally heavy rainfall as a frontal boundary slowly pushes
  southeast. 8 to 10 inches of rainfall is expected across east-central
  Oklahoma and northwest Arkansas with locally higher amounts
  approaching 15 inches.

* The heavy rainfall will likely lead to widespread and potentially
  life threatening flash flooding.  Several rivers will likely go
  into moderate to major flood including the Illinois river and Lee
  Creek at Van Buren. Beaver Lake dam in northwest Arkansas could
  begin to release water which would impact areas downstream.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

If you are in the watch area, keep informed, and be ready for quick
action if flash flooding is observed or if a warning is issued.
Persons living in low lying areas along main-stem rivers should
monitor the latest forecast and be ready to evacuate to higher
ground.

Do not drive your vehicle into areas where water covers the road
to unknown depths. Take a different route to reach your destination
or wait until the water recedes. Remember, most flood related
deaths occur in automobiles and flooding is the leading cause of
weather related deaths.

A flash flood watch means rapidly rising water or flooding is
possible within the watch area.
