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...Limited.
AREA...Southeast Oklahoma and west central Arkansas
        ...Parts of northeast Oklahoma overnight.
ONSET...Ongoing.

DANGEROUS HEAT.
RISK...Limited.
AREA...Southeast Oklahoma and west central Arkansas.
ONSET...Afternoon.


DISCUSSION...
Isolated thunderstorms may linger across southeast Oklahoma
and west central Arkansas after sunrise...however storm chances
will continue to move southeast away from the area through the
morning. Additional thunderstorms may approach the area late
tonight. However...these storms are expected to be in a weakened
state at the time they enter northeast Oklahoma...thus limiting
overall coverage and intensity.

Additionally...High relative humidity values in place will
combine with warm afternoon temperatures...resulting in heat index
values between 98 and 103 degrees this afternoon across southeast
Oklahoma and west central Arkansas.


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

.DAYS TWO THROUGH SEVEN...Friday through Wednesday.
FRIDAY...Thunderstorm Potential...Dangerous Heat Potential...Heavy Rain Potential.
SATURDAY...Thunderstorm Potential...Dangerous Heat Potential.
SUNDAY through TUESDAY...Thunderstorm Potential.
WEDNESDAY...Thunderstorm Potential...Heavy Rain Potential.

EXTENDED DISCUSSION...
Better chances for organized convection will come Friday evening
and overnight as a storm complex moves south into the region.
Additional moderate to heavy rainfall may raise flood concerns
over locations that have seen several rounds of heavy rainfall
this week. The wet pattern breaks by the weekend as some upper
level ridging takes place in the wake of the departing storm
complex. Heading into early next week...thunderstorm chances
overall will remain low...with any isolated storms remaining
confined to the late afternoon or early evening hours. Storm
coverage may increase towards the middle of next week as a frontal
boundary approaches the region.
