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

.DAY ONE...Today and Tonight

Showers and thunderstorms chances will increase today ahead of a
cold front that will move across Arkansas. Some strong and severe
storms will be possible, primarily over central and eastern
sections of the state. Damaging winds and large hail will be the
primary concerns, although isolated tornadoes cannot be rule out.
The severe weather threat will diminish later this evening as the
front moves east of Arkansas.

.DAYS TWO THROUGH SEVEN...Sunday Through Friday

The threat for hazardous weather will remain low through Sunday
night. However...showers and some thunderstorms will return to the
forecast Monday into Tuesday. There could be some potential for
strong to severe thunderstorms during this time frame...but
significant uncertainty exists on the overall track of this storm
system. As a result...refer to the forecasts in the coming days for
any changes to the potential for severe weather early next week. The
threat for seeing hazardous weather will then become low by the
middle of next week.

.Spotter Information Statement...

Spotter activation may be needed this afternoon and early this
evening.
