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

.DAY ONE...This Afternoon and Tonight.

SIGNIFICANT WINDS.
RISK...Limited.
AREA...Eastern Oklahoma and Western Arkansas.
ONSET...Ongoing.

FIRE WEATHER DANGER.
RISK...Elevated.
AREA...Eastern Oklahoma and far Northwest Arkansas.
ONSET...Ongoing.

DISCUSSION...
Fire weather concerns will continue through the afternoon hours as
a result of record high temperatures, relative humidity values
from 20 to 35 percent, and south to southwest winds gusting 25 to
30 mph at times. The lowest relative humidity values and highest
winds should be offset from each other, and as such, Red Flag
conditions are not expected to develop. The fire weather
conditions will improve during the early to mid evening hours.

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

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY.
TUESDAY...Thunderstorm Potential...Very High Fire Weather Potential.
WEDNESDAY AND THURSDAY...Thunderstorm Potential.
FRIDAY...Thunderstorm Potential...Heavy Rain Potential.
SATURDAY...Thunderstorm Potential.
SUNDAY...No Hazards.

EXTENDED DISCUSSION...
Elevated fire danger will exist again Tuesday, especially behind
a cold front that will stretch across northeast Oklahoma during
the afternoon. Gusty north to northeast winds behind the front will
result in increased spread rates despite higher relative humidity
values. Ahead of the front, continued well above normal temperatures
and south to southwest winds gusting to 20 mph will also fuel
afternoon fire danger.

Thunderstorm chances will increase beginning late Tuesday in the
vicinity of the aforementioned front, continuing into Wednesday
as the front begins to lift back to the north.

More widespread and potentially severe thunderstorm activity
continues to look likely toward the end of the week. A strong
upper level system and cold front will sweep through the area
Friday, with a line of storms likely to develop along the front
during the afternoon and into the evening hours as the front pushes
east. At this point, conditions appear favorable for at least
very large hail and damaging straight line winds Friday afternoon
and evening across a portion of eastern Oklahoma and western
Arkansas.
