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

.DAY ONE...Tonight.

THUNDERSTORMS WITH DANGEROUS LIGHTNING.
RISK...Limited.
AREA...northwest Arkansas and neighboring far northeast Oklahoma.
ONSET...towards sunrise.


SIGNIFICANT WINDS.
RISK...Limited.
AREA...Much of eastern Oklahoma and northwest Arkansas.
ONSET...ongoing.

FIRE WEATHER DANGER.
RISK...Limited.
AREA...Eastern Oklahoma and western Arkansas.
ONSET...ongoing.


DISCUSSION...
Fire weather concerns will continue into the early evening 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 fire weather conditions will improve during the
early to mid evening hours.

There is a slight chance of showers and thunderstorms late tonight
across far northeast Oklahoma and northwest Arkansas as a cold front
moves into the region.


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

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY.
TUESDAY...Thunderstorm Potential...High Wind Potential.
WEDNESDAY...Thunderstorm Potential.
THURSDAY...Thunderstorm Potential...High Wind Potential.
FRIDAY...Thunderstorm Potential...High Wind Potential...Heavy Rain Potential.
SATURDAY and Sunday...Thunderstorm Potential.

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.
