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

.DAY ONE...Today and Tonight

Thunderstorms will develop later today and especially this evening
and tonight across Arkansas, as an upper storm system and eventually
a cold front move across the region. Some of the storms will be
strong to severe, with large hail, damaging winds and a few
tornadoes possible.

Later this evening and into Sunday morning, the potential for strong
to severe storms will continue, as a cold front moves through the
state. These thunderstorms could also become severe, with damaging
winds possible with the strongest storms as this activity looks to
form into a larger, more organized line or complex. Large hail and a
few brief tornadoes will also be possible as this line or complex
moves southward through much of Arkansas Sunday morning. Locally
heavy rain will also be possible, resulting in an isolated flash
flood threat.

.DAYS TWO THROUGH SEVEN...Sunday through Friday

Sunday morning, the threat for seeing severe weather will have
decreased, but the cold front will still be dropping south across
the state. Additional thunderstorms will be possible Sunday
afternoon and evening across the southeast half of the state as the
cold front pushes through this region of Arkansas. Additional strong
to severe thunderstorms may again be possible during this period.

Calmer and drier conditions will be seen for Monday into Tuesday.
The threat for hazardous weather will then become low.

.Spotter Information Statement...

Spotter activation may be needed tonight and early Sunday.
