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

.DAY ONE...Today and Tonight.

AREA...west central Arkansas.
ONSET...Ongoing...but diminishing later this morning.

AREA...Eastern Oklahoma and west central Arkansas.
ONSET...Late Morning.

    AREA...Parts of far northeast Oklahoma...mainly west of highway 75.
    ONSET...After Midnight.

DISCUSSION... The tail end of a slowly departing area of rain and
thunderstorms has lingered over parts of west central Arkansas this
morning. Locally heavy rain fall across parts Crawford and Sebastian
counties has resulted in amounts between 2 and 3 inches...and flash
flood warnings have been issued for those areas. Rain and thunder is
expected to move further east later this morning.

Elsewhere...increased sun along with limited shower and thunderstorm
chances will result in a considerably warmer afternoon than what has
been seen the last several days. The previous rainfall has raised
relative humidity values across the entire area. That..and expected
sunshine will result in heat index values between 100 and 105
degrees across much of eastern Oklahoma and west central Arkansas.

Showers and thunderstorms are expected to develop to the west this
afternoon and evening along an approaching cold front. As the storms
move into northeast Oklahoma late tonight...one or two of the
stronger storms will be capable of producing marginally severe
wind gusts across northeast Oklahoma.

Local Spotter Activation May Be Needed.

.DAYS TWO THROUGH SEVEN...Wednesday through Monday.
WEDNESDAY and THURSDAY...Thunderstorm Potential.
FRIDAY...Thunderstorm Potential...Heavy Rain Potential.
SATURDAY through MONDAY...Thunderstorm Potential.

After a mostly dry Tuesday...a surface boundary in the area and
several upper disturbances will maintain thunderstorm chances in
the Wednesday to Friday period. By the weekend...some upper level
ridging begins to take place. At that time...thunderstorm chances
will begin to decrease across much of eastern Oklahoma and
northwest Arkansas...and a return to warmer and more humid
conditions that will likely continue into the next week.
