This Hazardous Weather Outlook is for a Large Part of Arkansas.

.DAY ONE...This Afternoon and Tonight

Showers and thunderstorms will continue to increase in coverage
this afternoon and evening ahead of a cold front that was moving
across northwest Arkansas. Some strong to severe storms are
possible, with damaging wind gusts being the primary concern.
Severe storms will also be capable of producing hail to one inch
in diameter, primarily over southwestern portions of Arkansas.

With winds over the state turning and increasing with height, a
couple of brief tornadoes can not be ruled out, especially later
this afternoon and into the early evening hours.

Heavy rainfall will accompany thunderstorm activity as well with
widespread rain accumulations of one to two inches and localized
heavier amounts. As such, a flooding risk will be prevalent over the
southeastern portion of the state Sunday afternoon through Monday
morning.

.DAYS TWO THROUGH SEVEN...Monday Through Saturday

Expect scattered showers to continue through Tuesday, with isolated
thunderstorms possible. Rain will once again affect the area late in
the week.

While isolated strong storms could occur in portions of the area,
widespread or organized severe weather is not expected at this time.

Due to heavy rainfall the last few days, as well as high soil
moisture content from snow melt, localized heavy rainfall will
continue to be a concern, especially over central and southern
Arkansas.

Continue to monitor the latest forecasts and statements from your
Arkansas NWS offices.

.Spotter Information Statement...

Spotter Activation may be needed later this afternoon and this
evening.
