This Hazardous Weather Outlook is for portions of south central
Arkansas, southwest Arkansas, north central Louisiana, northwest
Louisiana, southeast Oklahoma, east Texas and northeast Texas.

.DAY ONE...This Afternoon and Tonight...

Light rain with embedded showers along and near Interstate 20
will continue to lift North with additional development
expected to the North across East and Northeast Texas, Southwest
and South Central Arkansas and Southeast Oklahoma. A nearly
stationary frontal system near the Gulf Coast will lift North
as a warm front and into surface low pressure over parts of
South Central and North Central Texas. No hazardous weather is
expected.

.DAYS TWO THROUGH SEVEN...Monday through Saturday...

Persistent Southwest flow aloft will remain over the
four State Region providing additional moisture and
disturbances, resulting in an unsettled and wet weather pattern
well into the upcoming week. Milder temperatures will return
into the early part of the week in wake of a surface warm front.
Heavy rainfall is expected by Tuesday and Wednesday as a cold
front becomes a focus for thunderstorms over the area. Later in
the week, showers and isolated thunderstorms will remain possible.
The heavy rainfall that will be possible toward the mid week
will be a concern as saturated soils will provide more rapid
water runoff into the area lakes, rivers and streams. No
organized hazardous weather is expected at this time.

.SPOTTER INFORMATION STATEMENT...

Activation of emergency management personnel...amateur radio
operators...and storm spotters will not be needed through tonight.

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

.DAY ONE...This Afternoon and Tonight

Breezy south to southeast winds will continue over mainly the Ozark
Mountains of northwest Arkansas through tonight. Caution is advised
on area waterways. Otherwise, patchy dense fog will redevelop
tonight, and could reduce the visibility to less than a mile in
places.

.DAYS TWO THROUGH SEVEN...Monday Through Saturday

Windy conditions will be more widespread on Monday as a slow moving
cold front approaches from the north. Abundant moisture will be in
place, and this will lead to areas of heavy to excessive rain
Tuesday into early Wednesday across the northwest half of the
state.

Several inches of rain will be possible from Little Rock to the
north and west through Wednesday morning. Given this, there is a
moderate risk of flash flooding in this part of the region.

Subsequent periods of rain will follow statewide as the front stalls
to the south Thursday and lifts back into the area by Saturday. The
rain will be heavy at times.

Through next weekend, the forecast calls for four to six inches of
rain in much of Arkansas, with locally more than half a foot of
liquid. If this much rain occurs, flash flooding and river flooding
will become a concern.

.Spotter Information Statement...

Spotter activation will not be needed.
