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

.DAY ONE...This afternoon and Tonight.

SEVERE THUNDERSTORM.
RISK...Limited.
AREA...Far Northwest Arkansas and East Central Oklahoma.
    ONSET...Ongoing.

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

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

DISCUSSION...
Late this afternoon, a cold front extended from northwest Arkansas
through east central Oklahoma, south of Tulsa. North of the
boundary, winds were from the northeast and gusting to between 20
to 25 miles per hour. These winds will subside by late this
evening, but the strong flow will increase the fire danger north
of the front. The front will slowly shift south across the
area tonight...and the wind shift will pose a threat for those
involved with ongoing wildfire suppression efforts.

Isolated thunderstorms are possible mainly south of the front this
evening. The airmass south of the boundary remains moderately
unstable, but convergence has been too weak so far to support
widespread storm development. The chance for storms will lessen by
late evening. The main hazard from isolated storms tonight will
be lightning.

SPOTTER AND EMERGENCY MANAGEMENT ACTION STATEMENT...
Local spotter activation is not expected tonight.

.DAYS TWO THROUGH SEVEN...WEDNESDAY THROUGH MONDAY.
WEDNESDAY...Thunderstorm Potential.
THURSDAY...High Wind Potential...Fire Weather Potential.
FRIDAY...Severe Thunderstorm Potential...High Wind Potential...Heavy Rain Potential.
SATURDAY through Monday...Thunderstorm Potential...Fire Weather Potential.

EXTENDED DISCUSSION...
Isolated thunderstorm chances will persist through Wednesday night
as the passing front moves back north as a warm front.

A strong upper level storm system will arrive by Friday with a
widespread chance for showers and storms. Severe thunderstorms
appear possible with damaging winds likely to be the main threat.
A few areas may receive locally heavy rainfall as well. The
potential for large hail may increase Friday night as the upper
low passes.

The pattern looks active through the extended period with chances
for storms each day of the weekend.
