Rainfall amounts could be heavy at times in southwest and central
Arkansas into the overnight with minor flooding possible.
Otherwise, this needed rainfall will continue to increase in

of the cold front. Damaging winds and isolated tornado activity
will remain the primary threats for our area into the afternoon.
The rain will quickly clear out by around sunset with cold and dry
air to start the new week. A weak upper low on approach may touch
of some showers beyond midweek with the next cold front early in
