...ACTIVE WEEK AHEAD WITH SEVERE WEATHER AND HEAVY FLOODING RAIN
POTENTIAL...

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

.DAY ONE...Tonight.

No hazardous weather is expected at this time.

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

.DAYS TWO THROUGH SEVEN...TUESDAY THROUGH SUNDAY.
TUESDAY...Severe Thunderstorm Potential...High Wind Potential...Heavy Rain
            Potential.
WEDNESDAY...Severe Thunderstorm Potential...Heavy Rain Potential.
THURSDAY...Thunderstorm Potential.
FRIDAY and SATURDAY...Severe Thunderstorm Potential...Heavy Rain Potential.
SUNDAY...No Hazards.

EXTENDED DISCUSSION...

An active weather pattern will develop this week with
multiple rounds of potential severe weather and heavy flooding
rainfall.

A strong cap will remain in place for much of the day Tuesday,
suppressing thunderstorm development until early evening.
Scattered strong to severe storms will develop along a cold front
as it moves into northeast Oklahoma. Any storms that develop will
have the potential to be severe with large hail and damaging winds
the main threats. Tornado potential is expected to be low. The
severe threat will continue into the day Wednesday across
southeast Oklahoma and northwest Arkansas before the convective
line sweeps east of the area.

A stronger storm system is expected to affect the region by late
in the week and into the weekend, with an increased threat for
severe weather as it interacts with a pre-existing frontal
boundary. The most likely time frame for severe storms in our area
appears to be Friday and Saturday, however much uncertainty
remains regarding details such as the front location. Heavy
flooding rainfall is also expected to the north of the front, and
this will be most likely along and north of I-40. Flash flooding
and river flooding are likely to occur based on recent heavy
rainfall across the region. Severe weather and flooding rain
potential will end by Sunday as a cold front pushes east of the
region.

EMERGENCY MANAGEMENT PLANNING STATEMENT...

Continue to monitor future forecasts and outlooks, especially
concerning severe weather and flooding potential late in the week
into the weekend. Overall timing and specific severe weather
threats will continue to be refined.
