The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS New Orleans, LA wrote its last area forecast discussion before the first event at Jul 14, 8:20 AM CST, 2 hours 45 minutes earlier.
Area Forecast Discussion
National Weather Service New Orleans LA
920 AM CDT THU JUL 14 2016
.UPDATE...Have sent out a quick update to the forecast. Due to
this morning sounding showing much higher moisture and instability in
place have upped POPS for much of the area. This is especially so
along the southshore where the seabreeze and lakebreeze can
collideand also about 10-40 miles north and northwest of Lakes
Pontchartrain and Maurepas, away from the lake shadow. Rain will
likely get into the New Orleans metro early, much like yesterday,
and then around the Baton Rouge metro and north of the lake and
around the Pearl River this afternoon. With the amount of
instability and moisture in place the wet microburst numbers are
on the higher end so we can not rule out a few strong to severe
microburst. /CAB/
&&
.PREV DISCUSSION... /issued 823 AM CDT THU JUL 14 2016/
SOUNDING DISCUSSION...The sounding this morning indicates a lot
of instability with mixed layer CAPE at 2100 J/KG and most
unstable much higher. Given the profile some strong downbursts are
possible from storms that can pulse up quickly. Though the
convective temp is 90 F so coverage may be slightly more than
yesterday... this could keep any one storm from getting too
strong. PW is above average at 2.01 inches and with the deep warm
cloud layer storms will be efficient rain makers. Winds are
southwest at the sfc then more westerly by 800 mb but remain
light. The flow is northeasterly by 600 mb through the rest of the
profile.
Krautmann
PREV DISCUSSION... /issued 430 AM CDT THU JUL 14 2016/
SHORT TERM...Latest surface analysis continue to show a ridge of
high pressure Southeast United States and north half of Gulf of
Mexico. Light south flow was noted over Texas and Lower
Mississippi Valley. Precipitable water plots revealed 1.7 to 1.8
inches along the Upper Texas Coast to Florida peninsula with
values decreasing to 1.5 inches up to the Mid South. Upper air
analysis showed a high over the southwest CONUS, a short wave
from central Missouri to east Oklahoma, another wave over western
Kansas and a weak trough axis from Georgia to north central Gulf
of Mexico.
Upper level high will remain over southwest CONUS as the two waves
track east and southeast through Saturday. This will allow the
weak trough axis to retrograde west of the forecast area today
through Friday and maintain 30 to 50 pops each day through
Saturday. The highest rain chances will be across the southern
half of the CWA especially near the southshore where the seabreeze
and lakebreeze boundaries collide. As for strong/severe, not
anticipating much in the way of that. 18
LONG TERM...
Medium range models continue to suggest the middle portions of
the country baking next week while we could be right on the edge
of decent rain chances. High over southeast CONUS is expected to
build to the east over towards the Southern Plains and Mid-
Mississippi Valley later this weekend and our trough axis pushes
west under the ridge/high into Mexico. Sinking air from the high
and increased heights will decrease coverage of convection and
allow temps to rise at the same time. Northern zones will see less
convection than the coast. As a result, Southwest Mississippi and
East Central Louisiana could see highs in the mid to upper 90s
next week. 18
&&
.AVIATION...Widely scattered convection is continuing overnight
and is possible throughout the day on Wednesday as well. Coverage
is likely to be similar to what was seen on Tuesday. Overall, VFR
conditions are expected at all of the terminals through the entire
forecast period outside of any shower and thunderstorm
development. 98/SO
&&
.MARINE...Quiet conditions will persist across the coastal
waters through the week as high pressure sets up east of Florida
and dominates the Gulf of Mexico. A general onshore wind of 5 to
10 knots can be expected along with seas of 1 to 2 feet. Scattered
storms will be the main concern all week. These storms could
produce brief periods of gusty winds, higher waves, lightning, and
possibly waterspouts. 98/SO

1 lightning. Local standard time, as filed.
Two men who had been working on a roof in the 11800 block of Old Hammond Highway sought shelter under a tree as thunderstorms passed through. Lightning struck the tree, killing one of the men and injuring the other. The time of the event was estimated.
As the offices recorded each death: direct deaths were caused by the weather itself, indirect ones by something it set in motion.
