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

.DAY ONE...Tonight.

SEVERE THUNDERSTORM.
RISK...Limited.
AREA...Eastern Oklahoma and Northwestern Arkansas.
ONSET...Ongoing.

HEAVY RAIN AND FLASH FLOOD.
RISK...Limited.
AREA...Northeastern Oklahoma and Northwestern Arkansas.
ONSET...Ongoing.

DISCUSSION...
An organized complex of thunderstorms continues to move eastward
across far northeastern Oklahoma into northwestern Arkansas. Strong
gusty wind to near 60 mph is possible with some of this activity
through midnight. The outflow boundary associated with the
thunderstorm complex has pushed into southeastern Oklahoma and will
eventually push into west central Arkansas. Any further thunderstorm
development overnight will likely be along and north of this
boundary.

Due to very moist conditions, some locally heavy rainfall occurred
across portions of northeastern Oklahoma Tuesday evening. Additional
locally heavy rainfall overnight may result in flooding, if it
occurs where the heavy rain occurred already. Any flood problems
should remain isolted as widespread heavy rainfall is not expected.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
Local Spotter Activation May Be Needed.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday.
WEDNESDAY...Severe Thunderstorm Potential.
THURSDAY through MONDAY...Thunderstorm Potential.

EXTENDED DISCUSSION...
A surface boundary in the area and several upper disturbances will
maintain thunderstorm chances in the Wednesday to Friday period.
The best chance of severe thunderstorms and locally heavy rain will
occur Wednesday, resulting from high instability and strengthening
wind fields. By the weekend, some upper level ridging begins to take
place, leading to decreasing thunderstorm chances and a return to
warmer and more humid conditions that will likely continue into the
next week.
