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

.DAY ONE...Today and Tonight

Scattered showers and thunderstorms will be possible in a large
part of Arkansas today and tonight. The western half of the state
will see better chances for thunderstorms. Although widespread
severe weather is not expected, a few strong to briefly severe
storms are possible.

These storms would briefly be capable of producing damaging winds,
hail and locally heavy rainfall. Localized flash flooding may
occur as storm movement is expected to be slow and rainfall rates
very high.

Patchy fog is possible in much of the state this morning. The fog
will be locally dense in outlying areas, valleys and near bodies
of water, reducing visibility to less than one quarter of a mile
at times. The fog will dissipate after sunrise.

.DAYS TWO THROUGH SEVEN...Wednesday Through Monday

Isolated to scattered thunderstorms will be possible each day
through early next week. While widespread severe weather is not
expected at this time...a few strong to briefly severe thunderstorms
may be seen...especially during the afternoon hours each day. The
strongest storms could produce damaging downburst winds...hail and
locally heavy rainfall.

.Spotter Information Statement...

Spotter activation is not anticipated today, but any reports of
severe weather are requested.
