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

.DAY ONE...Today and Tonight

Showers and isolated thunderstorms remain in the forecast today.
That will be followed by an outbreak of severe weather and a
significant heavy rain event tonight and through the early morning
hours Saturday.

A large storm system approaching from the southern Plains will be
responsible for the active pattern. Thunderstorms will begin
developing in eastern Oklahoma and eastern Texas by late this
afternoon, and will remain in place through the evening awaiting the
arrival of the system. Once the system nears, a line of storms will
kick to the east and move through Arkansas tonight.

The incoming line of storms will likely bring widespread severe
weather to the region. The main concern will be damaging winds, and
there may be a few tornadoes as well. Where wind damage occurs,
gusts may be hurricane force or higher.

Ahead of the line, some data is indicating scattered thunderstorms
in southwest Arkansas this evening. This will be monitored very
closely, as storms such as these will have the potential to
spawn tornadoes.

Storms overnight will produce torrential downpours. Two to more than
three inches of rain is expected to dump in much of the state. Given
that vegetation is dormant and not consuming much ground water,
downpours will runoff quickly, and this will increase the flash
flood potential.

This event will also feature windy conditions. South to southeast
winds at 10 to 20 mph today will increase to 20 to 30 mph tonight
before shifting to the northwest. Gusts could reach 40 mph in
portions of eastern Arkansas.

.DAYS TWO THROUGH SEVEN...Saturday Through Thursday

Precipitation will gradually taper off on Saturday as colder air
filters into Arkansas. Lingering light rain will change to light
snow in the Ozark Mountains of the northwest. Some spots could pick
up a half inch to an inch of snow, mainly on grassy areas. Roads
will remain wet, with icy patches possible Saturday night as
temperatures drop below freezing.

.Spotter Information Statement...

Spotter activation may be needed tonight and early Saturday.
