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

.DAY ONE...Today and Tonight

Isolated thunderstorms could develop this afternoon, mainly across
northern portions of the state, although a stray thunderstorm
cannot be ruled out elsewhere. Lightning, gusty winds, and heavy
rain will be possible with any storms.

In addition, an approaching front will bring increased chances of
rain -- some heavy -- beginning late this evening and into
tonight. The initial threat for heavy rain and isolated flooding will
be across northern Arkansas with the threat spreading south over
time.

.DAYS TWO THROUGH SEVEN...Wednesday Through Monday

As the cold front pushes further south, heavy rain will
overspread much of the area. Isolated flooding will be possible
anywhere along or near the front, which will remain nearly
stationary over western, central, and southern Arkansas through
late week. Isolated strong storms cannot be ruled out, although
the threat for widespread severe weather remains low. Additional
rainfall will be possible through the weekend and into next week.

.Spotter Information Statement...

Spotter activation is not likely today or tonight.
