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

.DAY ONE...This Afternoon and Tonight.

AREA...Northeast Oklahoma
ONSET...Late Afternoon or evening.

AREA...Eastern Oklahoma and northwest Arkansas.

AREA...Eastern Oklahoma and northwest Arkansas.

Much of the thunderstorm activity has pushed off to the northeast as
of early afternoon. However, scattered showers along with a few
thunderstorms will remain possible possible through the afternoon
as a very moist airmass remains across the region. Low chances for
a few severe thunderstorms will exist later today and evening across
northeast Oklahoma with cold front that will linger just to the
northwest. The marginal severe weather chances will extend into
the overnight hours as the low level jet increases. The main
threat from any severe storm would be large hail. While less of a
severe threat is expected further south and east, storms across
southeast Oklahoma and into northwest Arkansas overnight will
be capable of producing locally heavy rainfall.

South winds will remain breezy through the day and into tonight with
frequent gusts over 30 mph likely.

Local Spotter Activation May Be Needed.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday.
TUESDAY...Thunderstorm Potential...High Wind Potential...Heavy Rain Potential.
WEDNESDAY...Winter Weather Potential.
THURSDAY and FRIDAY...Thunderstorm Potential...Heavy Rain Potential.
SATURDAY...Thunderstorm Potential.
SUNDAY...No Hazards.

Several rounds of widespread shower and thunderstorm activity are
expected throughout the week, with the first round of significant
rainfall expected Tuesday and Tuesday night as the cold front
begins to push into the region. Locally heavy rainfall is likely
across portions of southeast Oklahoma into northwest Arkansas with
around 1 to 3 inches of rain possible as these locations will be
within a deep moist axis.

A period of light freezing rain will be possible across parts of
northeast Oklahoma late Tuesday night into early Wednesday
precipitation that lingers before temperatures rise above
freezing. There still remains uncertainty concerning icing
potential, so stay aware of the latest forecasts.

Warmer temperatures for the latter part of the work week will
coincide with additional chances for widespread, heavy rainfall.
The deep moist axis will once again setup across southeast
Oklahoma and northwest Arkansas, and additional amounts will have
the potential to create flash flooding and mainstem river
flooding by late Thursday or Friday, particularly areas that
remain saturated by the heavy rainfall earlier in the week.

With a very unsettled pattern in place for this week, please pay
attention to the latest updates, and includes any flash flood and
river flood watches that may be posted given the current flood
potential. Overall rain amounts and areal coverage of rainfall
will be refined with later forecasts.
