What forecasters said that day

The local office's own words before this river flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Lake Charles, LA wrote its last area forecast discussion before this river flood warning went out at Apr 10, 10:01 AM CDT, 1 hour 55 minutes earlier.

Area forecast discussion, Apr 10, 10:01 AM CDT, 1 hour 55 minutes before

Area Forecast Discussion
National Weather Service Lake Charles LA
1001 AM CDT Sat Apr 10 2021

.UPDATE...
While forecast overall is trending nicely with regard to showers
and storms slowly exiting the area, have noticed some back
building of storms near Vermilion Bay area. This fits well with
thickness difluence shown in the RAP, HRRR and 12z GFE. Will
increase POPs slightly through late afternoon over those areas.

Frontal boundary over western parts of forecast area is correlated
fairly well with clearing line and should move through the area
this afternoon.

No other updates planned.

PREV DISCUSSION... /issued 350 AM CDT Sat Apr 10 2021/

DISCUSSION...
An active morning is ongoing as expected with local 88Ds showing
the primary round of strong/severe storms just about out of the
forecast area. However widely scattered showers/storms associated
with the cntl CONUS trof/pre-frontal sfc trof are now beginning to
pop up over the nwrn zones and upstream. Sfc analysis shows weak
low pressure over the TX Piney Woods with the cold front extending
swwd into the Hill Country. Behind the front, a brisk nrly flow is
noted with dewpoints down into the 40s...meanwhile over our
forecast area, temps are ranging from the 60s in rain-cooled air
over the nrn zones to the lower/mid 70s over the majority of the
area.

Convection will remain possible through the remainder of the
overnight across the forecast area before the front sweeps through
during the day and shuts off all the precip. Meanwhile, some of
the fog guidance is hinting at patchy fog mainly near the coast
through mid-morning. Skies will gradually clear with the arrival
of drier air through the column. Where CAA can get started
earlier, temps are progged to max out in the upper 70s (around
climo for the date)...while further south, highs in the lower 80s
are expected. A seasonal (or slightly cooler than normal) night
looks on tap as the 40s dewpoint airmass filters over the area,
with wakeup temps for Sunday expected to run from the upper 40s to
mid 50s (slightly warmer near the coast). With a wrly flow in
place aloft, dry conditions will persist through Sunday. Temps
are progged to begin warming with highs again creeping into the
mid 80s across the nwrn zones.

Slim rain chances return to the forecast, primarily over Acadiana
for Monday afternoon as the old frontal boundary begins to lift
back nwrd and wash out. Meanwhile, our next shortwave digging
through the swrn CONUS will allow deepening moisture to increase
while also pushing our next frontal boundary quickly through the
forecast area for Tuesday before stalling over the nrn Gulf. The
presence of continued abundant moisture behind the front and a
series of disturbances traversing the wrly flow aloft will lead to
mainly small rain chances through the remainder of the forecast
period.

MARINE...
Beyond today, no headlines are anticipated on the coastal waters
through the period.
