The episode as NWS LIX wrote it up.
A line of thunderstorms moved across southeast Louisiana and the adjoining coastal waters during the early afternoon hours of the 27th.
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 Apr 27, 11:33 AM CST, 1 hour 27 minutes earlier.
AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NEW ORLEANS LA
1233 PM CDT WED APR 27 2016
.AVIATION...
BROKEN LINE OF THUNDERSTORMS WILL IMPACT THE TERMINALS THIS
AFTERNOON AND HAVE INCLUDED PREVAILING OR TEMPO THUNDER FOR THE
MOST LIKELY TIMING. SOUTH/SOUTHEAST WINDS IN THE 10 TO 15 KNOT
RANGE WILL EASE AFTER SUNSET...BUT ARE EXPECTED TO REMAIN HIGH
ENOUGH TO PREVENT WIDESPREAD FOG FROM FORMING. HOWEVER...SEVERAL
HOURS OF IFR TO POSSIBLY LIFR CIGS ARE EXPECTED TONIGHT. EXPECT
CONDITIONS TO BEGIN IMPROVING AFTER SUNRISE THURSDAY.
&&
.16Z SOUNDING DISCUSSION...
CAPPING INVERSION JUST BELOW 700MB HAS WEAKENED A FEW DEGREES FROM
THE 12Z KLIX SOUNDING AND SURFACE BASED PARCELS ARE UNINHIBITED WITH
AROUND 3600 J/KG OF INSTABILITY AVAILABLE. WEAKENING HAS BEEN
OCCURRING WITH THE MAIN SQUALL LINE THIS MORNING...BUT HAVE NOTICED
RECENT DEVELOPMENT AHEAD OF THE SQUALL LINE ALONG AND EAST OF I-55.
DAMAGING WIND THREAT CONTINUES AS THE DOWNDRAFT CAPE VALUE IS NEARLY
UNCHANGED AND DRIER AIR HAS MIXED DOWN TO AROUND 2300 FEET. MID-
LEVEL LAPSE RATES REMAIN STEEP AND THE FREEZING LEVEL AND WET BULB
ZERO LEVEL HAVE HAD ONLY MINOR CHANGES. HAIL THREAT MAY BE
DIMINISHED SOME DUE TO BOUNDARY LAYER WARMING AND DRIER AIR IN THE
LOWER LEVELS.
&&
PREV DISCUSSION... /ISSUED 324 AM CDT WED APR 27 2016/
SYNOPSIS...
HIGH PRESSURE CENTERED OFF THE ATLANTIC COAST THIS MORNING. LOW
PRESSURE WAS CENTERED OVER KANSAS AT 2 AM. A WELL DEVELOPED
SQUALL LINE EXTENDED FROM NORTHWEST MISSOURI TO THE ARKLATEX...TO
THE BIG BEND OF TEXAS. LOCALLY...SOME LOWER CLOUDS HAVE MOVED INTO
THE WEST HALF OF THE CWA THIS MORNING...BUT NO PRECIPITATION IS
OCCURRING. TEMPERATURES RANGED FROM THE MID 60S NORTHEAST TO
MID 70S SOUTHWEST AT 2 AM. DEW POINTS GENERALLY LAGGED
TEMPERATURES BY A COUPLE DEGREES.
SHORT TERM...
SHORT TERM PROBLEM WILL BE CONVECTIVE THREAT TODAY. SYNOPTIC
MODELS DO NOT SEEM TO BE CATCHING CURRENT CONVECTIVE TRENDS...WITH
CONVECTION NOT REACHING THE AREA UNTIL THIS AFTERNOON...IF AT ALL.
MESOSCALE MODELS PAINT A DIFFERENT PICTURE. HRRR HAS SQUALL LINE
REACHING WESTERN PORTIONS OF THE AREA AROUND MID-MORNING...ABOUT
15Z. NMM IS A COUPLE HOURS SLOWER. EXTRAPOLATION OF RADAR OVER THE
LAST 3 HOURS WOULD HAVE THE PRECIPITATION IN EVEN QUICKER THAN
THAT...CLOSER TO 13Z. EVENING LIX SOUNDING WAS ALREADY SUPPORTIVE
OF CONVECTION. IT APPEARS THAT SYNOPTIC MODELS COULD BE OVERDOING
WARMING AROUND 700 MB...SHOWING A CAP THAT MAY NOT BE THERE THIS
MORNING. UNLESS THERE IS A SIGNIFICANT CHANGE IN CONVECTIVE TRENDS
OVER THE NEXT HOUR...PLAN TO GO MUCH CLOSER TO MESOSCALE MODELING
ON RAIN CHANCES FOR TODAY. THIS MEANS MOST AREAS WILL HAVE AT
LEAST A BRIEF PERIOD OF LIKELY POPS TODAY. SPC HAS ABOUT NORTHWEST
HALF OF CWA IN A SLIGHT RISK WITH THE REMAINDER IN A MARGINAL
RISK. THIS LOOKS REASONABLE WITH DAMAGING WINDS AND HAIL THE MAIN
THREATS. TEMPERATURE TRENDS BASED ON MORNING CONVECTION...BUT HAVE
SIGNIFICANT BUST POTENTIAL DEPENDING ON HOW THE SCENARIO UNFOLDS.
WILL BE CARRYING HIGHER POPS TONIGHT THAN SYNOPTIC MODELS WOULD
INDICATE BASED ON POTENTIAL REDEVELOPMENT DURING THE AFTERNOON. ON
THURSDAY...ORGANIZED CONVECTION LESS LIKELY...BUT FORECAST
SOUNDINGS STILL SHOW PLENTY OF INSTABILITY AVAILABLE FOR LOCALIZED
CONVECTION. SHORTWAVE RIDGING SHOULD SUPPRESS MOST CONVECTION ON
FRIDAY.
WILL TREND TOWARD MIDDLE/LOWER END OF TEMPERATURE GUIDANCE
ENVELOPE ON HIGH TEMPERATURES SINCE SYNOPTIC MODELS SEEM TO BE
UNDERPLAYING CONVECTION.
LONG TERM...
DID NOT MAKE SIGNIFICANT CHANGES TO EXTENDED FORECAST AT THIS
TIME. LOOKS LIKE THE BEST CHANCES OF CONVECTION MAY BE SATURDAY
NIGHT INTO SUNDAY AS A SHORTWAVE ROLLS THROUGH THE MIDDLE
MISSISSIPPI RIVER VALLEY. PREVIOUS PACKAGE HAS THIS ALREADY IN
PLACE.
MARINE...
INCREASED ONSHORE FLOW OF 15 TO 20 KNOTS SHOULD SPREAD INTO ALL OF
THE GULF WATERS AND THE BRETON AND CHANDELEUR SOUNDS BY TONIGHT.
HAVE EXERCISE CAUTION HEADLINES IN PLACE FOR THE WESTERN WATERS FOR
TODAY...AND EXPECT TO SEE THESE HEADLINES EXTENDED TO THE EASTERN
WATERS FOR TONIGHT. THE PRESSURE GRADIENT OVER THE GULF SHOULD
RELAX A BIT ON THURSDAY AS THE HIGH OVER THE EASTERN GULF BECOMES
MORE DOMINANT. HOWEVER...ANOTHER LOW PRESSURE SYSTEM MOVING INTO
THE PLAINS SHOULD INCREASE ONSHORE FLOW BACK INTO THE 15 TO 20 KNOT
RANGE BY FRIDAY AND THEN KEEP THESE STRONGER WINDS IN PLACE THROUGH
THE WEEKEND AS THE LOW PRESSURE SYSTEM SLOWLY PUSHES EAST ACROSS THE
MIDWESTERN STATES. THE ONSHORE FLOW SHOULD WEAKEN BACK TO AROUND 10
KNOTS BY EARLY NEXT WEEK AS A HIGH PRESSURE SYSTEM BECOMES CENTERED
OVER THE CENTRAL GULF.
