humidity values dropping to around 40 percent will result in
a elevated fire danger for much of the area into the early
evening.

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.

Rain Potential...Fire Weather 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 mainly west
of Highway 75 behind the dryline. Gusty, dry southwest winds of
25 to 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.
