The episode as NWS LIX wrote it up.
A cold front that was moving south across Mississippi and Louisiana on 6/9 moved across portions of the the local coastal waters. Sufficient instability was still in place from the previous afternoon to support severe thunderstorms along the boundary. It then stalled across the coastal waters near the mouth of the Mississippi River on the morning of the 10th. Not long after stalling, it began to lift back north as a warm front. As it did so, storms began training across New Orleans metro, resulting in flash flooding. Moving into the afternoon hours, the warm front continued north. Daytime heating destabilized the atmosphere even more within the warm sector, south of the front. This provided an environment which supported severe thunderstorms with damaging wind gusts over both land and marine areas.
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 Jun 10, 11:35 AM CST, 1 hour 30 minutes earlier.
Area Forecast Discussion...UPDATED National Weather Service New Orleans LA 1235 PM CDT Fri Jun 10 2022 ...18z Aviation Update... .AVIATION... Convection is impacting several terminals this afternoon. Respectively added MVFR with some brief reductions to IFR expected. TEMPOs were used for the next potential batch of convection later on this afternoon and early evening. Short fused tempos may be possible again after 00z for the western terminals based on the more recent guidance, but at this juncture until more confident...left dry. Some patchy fog possible tonight in the fog favored areas, especially if skies clear. Otherwise, VFR conditions after sunrise on Saturday for most locations. && .PREV DISCUSSION... /issued 1102 AM CDT Fri Jun 10 2022/ ..MORNING UPDATE... A bit busy across the nearshore waters and portions of the New Orleans metro (especially eastern portions). Diurnally driven convection developed over the waters overnight. This allowed for several boundaries to develop and move onshore allowing for more convective development to take place across the land based zones of SE LA this morning. The flow is mostly parallel to these mesoscale boundaries and has allowed for multiple storms to develop (back build). This activity has a PWAT of nearly 2.0" (as seen on the LIX 12z RAOB) to work with, which is allowing for some efficient rainfall rates. In fact, with the back building and heavy rates, some hydro concerns have developed generally over portions of Orleans and St Bernard Parishes. Scattered convection will remain possible across the region as 1) an H5 impulse continues to move southward (more on that later) and 2) plenty of instability with steepening mid-level lapse rates. Looking up stream a MCS has developed and is surging southward toward our area from the ArkLaTx/ArkLaMiss region in association with the aforementioned mid level impulse within the NW upper flow. Parameters support mostly a strong damaging wind threat, but with the steeper mid level lapse rates, some small hail cannot be ruled out. Timing of the MCS looks to have sped up just a bit with the leading edge of the complex arriving into our SW MS Counties around or just after the noon hour. Updates to POPs and QPF are already sent. PREV DISCUSSION... /issued 347 AM CDT Fri Jun 10 2022/ SHORT TERM (Today through this Weekend)... Upper level analysis still shows a ridge centered around Arizona and and a broad trough over the eastern third of the country thats now east of the Appalachian Mountains. That trough has eroded the eastern side of the ridge aloft that's kept the CWA dry. A weak frontal boundary that moved into the local area yesterday from the trough has stalled. It will be the focus for sporadic showers and storms this morning. The bigger concern for weather impacts will be later in the day. An MCS, already very obvious on GOES-16 in Oklahoma. There's a strong consensus amongst CAMs that the MCS will track across southern AR into northern LA/MS before reaching southeast LA and southern MS this afternoon(right at peak heating!). Looking at model soundings, its pretty much what you would expect for summer with extremely high CAPE values and DCAPE well over 1000j/kg. Surface dewpoint depression is really high too. That combo of an MCS moving into an extremely unstable environment could set the stage for a fairly extensive damaging wind event across the CWA. SPC has a Slight to Enhanced Risk for severe weather and couldn't be in more agreement with them on the risk level and placement of it. The biggest question mark is exactly where it will track. The ridge mentioned above will still be over the Desert Southwest Saturday and already expanding back east across the northern Gulf Coast as the trough shifts east. This may be enough to start moderating temps but likely not enough to stunt convection. So still looking at afternoon POPs. Sunday, however, the center of the ridge looks to slide east to around northern LA/southern AR. That position will more likely drop convection to a minimum. We'll likely also be watching for heat advisory conditions as heat indices move well into the 100's. MEFFER LONG TERM (Next week)... The upper level ridge centered just north of the CWA Sunday will slowly track towards the Appalachian Mountains by mid week. This should keep highs in the low to mid 90s and little to any chance for rainfall. Its not until the later half of the week that a northern stream trough starts to break down this ridge and convection returns. MEFFER Marine... There is currently a stalled frontal boundary draped from west to east across Lake Pontchartrain and Chandeleur Sound. Those areas north of the front will continue to see offshore winds until it dissipates later today. Otherwise, not much change in the forecast from day to day as a surface ridge centered east of the area expands westward across the Gulf of Mexico. This will result in local winds maintaining southwest to west direction. Speeds will vary from 5-10 knots to 10-15 knots overnight, typical of summertime pattern. There could be occasional nocturnal winds reach exercise caution speeds. MEFFER && .PRELIMINARY POINT TEMPS/POPS...
