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

.DAY ONE...Tonight

Showers and thunderstorms will affect the state tonight, as a storm
system moves through the region. Scattered strong to severe
thunderstorms will be possible, with the primary threats of damaging
winds and large hail possible. Also, a few tornadoes will be
possible. The storms ahead of the cold front will gradually move
across Arkansas later tonight and into the overnight. Additionally,
heavy rainfall will be a concern with any stronger storms, with
localized flooding and flash flooding possible.

Also, winds will be elevated today from the south, and be 10 to 20
mph, some gusts to around 25 to 30 mph. Caution is advised on
area bodies of water due to the increased winds.

.DAYS TWO THROUGH SEVEN...Saturday Through Thursday

The storm system will be pushing through Arkansas on Saturday, and
will gradually take the showers and thunderstorms to the east of
the state. Localized flooding could be on going with the heavy
rain from Friday night. Any remaining storms may contain heavy
rain before all moving out of Arkansas Saturday night. Much colder
air again will filter in behind the cold front, and spotty
locations will see around freezing temperatures Sunday and Monday
mornings. Mostly dry Monday and the coming week.

.Spotter Information Statement...

Spotter activation will be needed this evening and into the
overnight due to the potential of severe storms.
