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

.DAY ONE...Today and Tonight

Isolated to scattered thunderstorms are possible through tonight.
While a few strong storms are possible, the potential for
organized severe weather will be limited.

Meanwhile, the Arkansas River will continue to rise or remain high,
with major flooding continuing at all forecast points along the river.

.DAYS TWO THROUGH SEVEN...Thursday Through Tuesday

Major flooding continues along the Arkansas River. This is an historic
event, with record or near record crests occurring or projected.
Arkansas River levels will remain high for quite some time.

Scattered showers and thunderstorms will be possible over the next
several days into the weekend. Some storms could be strong to severe
with large hail and damaging winds the primary threats.

Heavy rainfall will also be possible, with amounts from 1 to 3
inches expected through the weekend, with locally higher amounts.
This will only increase the potential for flash flooding, as well
as prolong the ongoing river flooding. All interests should
monitor this forecast closely over the coming days.

For those working outdoors, assisting with the ongoing Arkansas
River flooding, be aware of the lightning hazard associated with
approaching thunderstorms. Have a shelter in mind should storms
approach your area.
