The radar

The Lake Charles radar (KLCH), 112 km from the middle of the area, began a volume at 21:09 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Slidell Radar S, LA (KSIL), launched 12:00Z, 9.2 hours before the alert went out and 226 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

.KEY MESSAGES...

- A Flood Watch has been issued for an area along and north of a Hardin
  county to Vernon to Rapides parish line from 4 AM Friday to 4
  AM Saturday. Widespread rainfall totals from 2 to 4 inches and
  locally higher amounts from today to Saturday AM.

- Periods of showers and thunderstorms will persist from tonight
  through Saturday morning when a cold front moves down into the
  region.

- Cool conditions will begin moving into cenLA as early as Friday
  AM and daytime high temps could be as low as low to mid 60s for
  areas north of hwy 190.

- Much cooler and dry conditions will arrive on strong northeast
  winds Saturday.

&&

.DISCUSSION...
(This evening through next Wednesday)
Issued at 219 PM CDT Thu Apr 30 2026

Two large areas of convection has developed, a corridor across
cenLA and  another along I-10. The northern area is in response
to upper shortwave perturbation moving across and the southern is
along a confluence boundary. Both areas have a robust airmass with
deep moisture and CAPE to openly use within an uncapped
environment. Thus, anticipate a scenario playing out similar to
what was seen north of our region yesterday. Corridors of heavy
rainfall with embedded areas of strong storms capable of producing
strong, damaging downdrafts and large hail. An embedded tornado
threat will exist but is not likely.

Most convection will die off with sundown but active jet aloft and
approaching shortwave from the west could keep light showers in
the region overnight.

Decently amplified upper trough comes through again on Friday with widespread
showers and thunderstorms expected. Heavy rainfall will be the
greatest threat as sfc conditions will not be so conducive for
severe conditions reaching the surface. There will exist an
isolated severe threat, though, if downdrafts can reach the
surface. This will persist until a strong cold front moves down
into the region with much cooler and drier air set to arrive on
Saturday morning.

Widespread heavy rainfall between today and Saturday morning
should  total 2 to 4 inches area wide with locally higher
amounts. Areas north and west of a Hardin to Beauregard and
Rapides parish line have already or will receive heavy rainfall
from recent days to today. Considering further rainfall
anticipated today and tomorrow, these areas are now under a flood
watch from 4 AM Friday to 4 AM Saturday.

This watch area may be expanded to include further regions based
on rainfall received today. Due to ongoing drought conditions and
low water catch basins, its unlikely that regions very far south
of the watch will need to be included. Continue to monitor the
forecast for further updates.

&&

.AVIATION...
(18Z TAFS)
Issued at 219 PM CDT Thu Apr 30 2026

Two boundaries of showers and thunderstorms are developing, one
across central LA and one across the I-10 corridor. Both areas
will bring about periods of heavy rainfall, frequent lightning and
volatile winds. In stronger storms, damaging wind gusts and large
hail will be possible as well.

A sagging cold front boundary will continue the period of showery activity
from now until Saturday morning when a cold front airmass moves
through the region.

In the interim and away from convection, anticipate low CIGs and
gusty variable winds around quasi-stationary boundaries.

&&

.MARINE...
Issued at 219 PM CDT Thu Apr 30 2026

A boundary sluggishly moving over the region should sink down
into coastal waters late tonight with strong offshore winds
developing thereafter. Showers and thunderstorms with downpours
are anticipated to develop and persist across coastal waters from
tonight through Saturday when a strong cold front moves into the
central Gulf.

Offshore winds will strengthen from west to east mid day thru
afternoon Friday. Strong winds will then persist into at least
Saturday morning. Winds and seas will diminish into Sunday morning
with onshore winds to resume at the start of the week.
