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

.DAY ONE...This Evening and Tonight

Scattered thunderstorms will remain possible through the overnight
hours. Widespread severe weather is not expected, but some
thunderstorms may produce gusty winds, hail and locally heavy
rainfall.

.DAYS TWO THROUGH SEVEN...Saturday through Thursday

Showers and storms will be possible virtually every day through
next week with the most widespread activity expected late weekend
into next week. Heavy rainfall and localized flooding will be
possible.

While all storms are accompanied by a lightning threat, some of
the stronger storms may produce locally strong wind gusts and
small hail. A few severe storms are possible, but at this time,
the timing and certainty of any severe threat remains unclear.

With several rounds of showers and thunderstorms expected through
the week, heavy rainfall could allow for rises on area lakes and
rivers.

Your best bet is to continue to monitor the latest forecasts and
outlooks from your National Weather Service as updates will be
made in the coming days.

.Spotter Information Statement...

Spotter activation could be needed this afternoon and evening over
about the northwest half of Arkansas.
