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...Western Arkansas and Far Southeast Oklahoma.
ONSET...This Afternoon.

DANGEROUS HEAT.
RISK...Limited.
AREA...Eastern Oklahoma and West Central Arkansas.
ONSET...Early Afternoon.

FIRE WEATHER DANGER.
RISK...Limited.
AREA...Eastern Oklahoma and Western Arkansas.
ONSET...Early Afternoon.

DISCUSSION...
Well above normal temperatures will continue today, resulting in
afternoon heat index values from 100 to 105 across much of eastern
Oklahoma and west central Arkansas. The hot conditions will also
combine with increasing southerly winds to lead to a limited risk
of rapid fire spread. Both the heat and fire spread threats will
improve during the evening.

A thunderstorm or two may also occur across portions of western
Arkansas and far southeast Oklahoma this afternoon to the east of
a line from Beaver Lake to Poteau. Any thunderstorms will diminish
by evening.

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

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday.
THURSDAY...Thunderstorm Potential...Very High Fire Weather Potential.
FRIDAY AND SATURDAY...Thunderstorm Potential...Heavy Rain Potential.
SUNDAY THROUGH TUESDAY...Thunderstorm Potential.

EXTENDED DISCUSSION...
Above normal temperatures will continue into Thursday, leading to
an uptick in the potential for rapid fire spread as southerly
winds increase further ahead of an approaching cold front.
Afternoon thunderstorms will again be possible Thursday across
portions of western Arkansas and far southeast Oklahoma.

More widespread showers and thunderstorms will begin to arrive
early Friday morning across portions of northeast Oklahoma,
spreading into the rest of the area by Saturday, as the
aforementioned cold front moves into the region. The increased
shower and thunderstorm potential will persist through the
weekend, especially across areas southeast of Interstate 44, with
a general drying trend expected from west to east early next week.
Locally heavy rainfall will be the main thunderstorm threat,
mainly Friday and Saturday.
