DISCUSSION...
Southerly winds will continue to gust to around 30 miles an hour
at times tonight. This will maintain a limited fire danger through
the overnight hours despite increasing humidity values.

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

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

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

EXTENDED DISCUSSION...
Showers and thunderstorms are expected to increase in areal coverage
during the day Friday along and ahead of 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, especially in far eastern
Oklahoma and western Arkansas. 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 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 mainly west of
Highway 75 behind the dryline. Gusty, dry southwest winds of 25 to
35 miles an hour during the afternoon will drop relative humidity
values to 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 some severe storm
potential.
