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

.DAY ONE...This Evening and Tonight.

SEVERE THUNDERSTORM.
	RISK...Limited.
	AREA...Northeast Oklahoma into Far Northwest Arkansas.
	ONSET...Through Tonight.

HEAVY RAIN AND FLASH FLOOD.
	RISK...Limited.
	AREA...Mainly North of Interstate 44.
	ONSET...Through Tonight.

DISCUSSION...
An isolated thunderstorm potential will remain possible into this
evening across Northeast Oklahoma into far Northwest Arkansas as
the atmosphere remains unstable. Sufficient instability will
support a limited large hail and damaging wind threat with any
development. Additional thunderstorms are also forecast to
develop along a frontal boundary stretched across Kansas. There
remains some potential that these additional storms could push
into parts of Northeast Oklahoma and far Northwest Arkansas late
evening and overnight tonight, with the greater potential for
locations along and near the Kansas border. The higher instability
looks to lift back into Kansas overnight, though a limited severe
potential with large hail and locally damaging winds could be
possible. Heavy rainfall which could increase flash flooding
concerns will also be possible through tonight within any of the
thunderstorm development.

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

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday.
TUESDAY...Thunderstorm Potential...Heavy Rain Potential.
WEDNESDAY...Severe Thunderstorm Potential...Heavy Rain Potential.
THURSDAY THROUGH SATURDAY...Thunderstorm Potential.
SUNDAY...No Hazards.

EXTENDED DISCUSSION...
Thunderstorm chances will continue to be possible during the day
Tuesday across Eastern Oklahoma and Northwest Arkansas. Greater
chances are forecast for Tuesday night into Wednesday morning as
additional storms developing out west look to spread eastward
into the region. These storms would pose at least a limited risk
of severe weather and also a heavy rainfall potential. Additional
rainfall on top of recent rains could continue to increase flash
flooding concerns Wednesday. By Wednesday afternoon into
Wednesday night, an upper level system will move into the Plains,
bringing potential for a more widespread severe weather threat
late Wednesday afternoon and Wednesday night. At this time, all
modes of severe weather could be possible over the region.
However, the extent of the severe threat will be heavily
influenced by convective trends from Tuesday night and Wednesday
morning. Thunderstorm chances look to exit Thursday morning with
additional chances returning Friday night into the weekend.
