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 yield a limited fire
weather danger, mainly across eastern Oklahoma. Conditions will
improve this evening.

Isolated thunderstorms may occur this afternoon across portions of
western Arkansas and far southeast Oklahoma to the east of a line
from Beaver Lake to Poteau. Any thunderstorms, if they develop, 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 and dry conditions continue into Thursday,
along with stronger south winds, leading to an elevated fire weather
danger across much of northeast Oklahoma and far northwest Arkansas.
Isolated 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 interacts with increasing tropical
moisture from the southwest. Locally heavy rainfall and some
flooding are possible. The heavy rain potential is then expected to
shift south and east of the region Sunday with the advancing front.
