634 AM CST Wed Feb 12 2020

This Hazardous Weather Outlook is for southern Arkansas, for
northern Louisiana, for northeast Texas and southeast Oklahoma.

.DAY ONE...Today and Tonight...

Showers and thunderstorms will continue to increase today, but
then greatly diminish from west to east this evening as the
surface low moves to our east and the cold front moves down into
the area overnight. The flash flooding threat will peak today with
our already super saturated soils and more heavy rains coming
ahead of the cold front. Stay tuned to NOAA weather radio for
additional flash flood warnings today.

.DAYS TWO THROUGH SEVEN...Thursday through Tuesday...

Cold air will spill back into the region fully driving out the
rain for a short time. However, light showers will return on
Saturday becoming more widespread perhaps into Sunday.
Then thunderstorms will resume early in the week and continue for
us into midweek ahead of our next cold front. A renewed flash
flooding threat will compound high waters on our rivers, bayous and
lakes.

.SPOTTER INFORMATION STATEMENT...

Activation of emergency management personnel, amateur radio
operators and storm spotters may be needed today for flash flood
reports primarily.
