...Severe Storm Potential Friday and Friday Night...


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...Elevated.
AREA...Eastern Oklahoma...mainly west of Highway 75.
ONSET...After 3 AM.


FIRE WEATHER DANGER.
RISK...Elevated.
AREA...Eastern Oklahoma and northwest Arkansas.
ONSET...Late Morning.

    Area at Greatest Risk...Northeast Oklahoma...mainly northwest of Interstate 44.

DISCUSSION...
Increasing south winds and warmer temperatures will lead to
increasing fire spread potential today ahead of an approaching
upper level system. Moisture will also be increasing, which will
keep the humidity above critical levels. However...the highest
spread rates can be expected across northeast Oklahoma where winds
may gust near 40 mph at times from late morning through the
afternoon.

Late tonight...thunderstorm chances will begin to increase across
parts of eastern Oklahoma ahead of an approaching dryline and
upper system. Storms late tonight are not expected to be
severe...however coverage of thunderstorms and severe potential
will increase after sunrise Friday.


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

.DAYS TWO THROUGH SEVEN...FRIDAY THROUGH WEDNESDAY.
FRIDAY... Severe Thunderstorm Potential...High Wind Potential...Heavy Rain Potential.
SATURDAY...Thunderstorm Potential.
SUNDAY...Severe Thunderstorm Potential.
MONDAY Through WEDNESDAY...Thunderstorm Potential.

EXTENDED DISCUSSION...
Showers and thunderstorms are expected to increase in areal coverage
Friday morning and afternoon along a dryline that will move east
across the region throughout the day. The primary severe weather
threats with these storms will be damaging straight line winds and
locally heavy rainfall. Additional storms may develop during the
overnight hours Friday as the upper level low moves overhead.
Storms associated with the upper low will have some potential for
quarter to half dollar size hail. Thunderstorm chances will
decrease from west to east Saturday as the upper low clears the
area.

Additionally...there is potential for a rapid increase in fire
danger Friday afternoon across northeast Oklahoma behind the dry
line. Gusty, dry southwest winds of 25-35 mph during the afternoon
will drop relative humidity values around 25% in these locations
during the afternoon.

An active weather pattern will resume late Sunday and likely
will continue well into next week. This will result in multiple
chances for thunderstorms, along with severe storm potential.
