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

.DAY ONE...Through Tonight

Scattered to numerous showers with a few thunderstorms will
continue to be possible through tonight, especially over central
and northeast portions of the state. Additional rainfall amounts
of one to two inches are possible, with locally heavier totals.

.DAYS TWO THROUGH SEVEN...Tuesday Through Sunday

Rain chances will continue on Tuesday but increase in coverage and
magnitude statewide Tuesday through Wednesday night, when locally
heavy rain could fall. At this time, the highest concern for
heavy rainfall will be from central into western Arkansas, where
heavy rains fell this morning. Additional rainfall will only add
to already saturated ground, with flash flooding possible. Through
Wednesday evening, additional rainfall amounts in excess of three
inches are possible, especially over western portions of the

This will be a multi-day rain event and help contribute to elevated
stream/river levels. The highest potential for flash flooding
appears to be in the Tuesday night through Wednesday evening time
frame when the heaviest of the rain is expected.

Arkansas, southwest Arkansas, north central Louisiana, northwest
Louisiana, southeast Oklahoma, east Texas and northeast Texas.

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

Showers and thunderstorms will increase across the region today,

out, with damaging winds, hail, and brief heavy rainfall possible.

.DAYS TWO THROUGH SEVEN...Tuesday through Sunday...

Showers and thunderstorms will again return to the region Tuesday
in advance of an upper level storm system that will progress
through the Southern Rockies and into West Texas and the Oklahoma
Panhandle by midweek. The threat for locally heavy rainfall and
flash flooding will increase Tuesday night and Wednesday across
East Texas, Southeast Oklahoma, portions of Southwest Arkansas and
possibly Western Louisiana, as a complex of showers and
thunderstorms moves into these areas. Some of these storms may

increases across these areas Tuesday night and Wednesday.
Widespread rainfall amounts of three to five inches are expected
this week across these areas this week, with isolated higher
amounts in excess of eight inches possible, especially over East

flooding on area creeks and bayous, rivers and lakes. This
unsettled weather pattern will continue Thursday and Friday,
before gradually diminishing from east to west this weekend.


Activation of emergency management personnel...amateur radio
operators...and storm spotters may be needed today across portions
