NWS Lake Charles, LA wrote its last area forecast discussion before the first event at Jun 9, 12:10 PM CST, 1 hour earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE LAKE CHARLES LA 110 PM CDT TUE JUN 9 2015 .DISCUSSION... 18Z TAF ISSUANCE. && .AVIATION... ISO/SCT SHRA/TSRA EXPECTED ACROSS MOST OF THE REGION THIS AFTERNOON. AN UPPER LEVEL DISTURBANCE CURRENTLY DIGGING S ACROSS THE LOWER MS VALLEY HAS GENERATED AN MCS OVER MS/SE LA EARLIER THIS MORNING. NEW AREA OF SHRA/TSRA HAS DEVELOPED JUST E OF THE ATCHAFALAYA RIVER...LIKELY AIDED FROM THE REMNANT OUT...MOVING W AROUND 15 MPH. THIS AREA IS EXPECTED TO CONTINUE TO THE WEST OR SOUTHWEST THIS AFTERNOON. THUS...CONTINUED TEMPO GROUPS FOR TSRA & MVFR VSBY/CEILING FROM 19-23Z FOR ARA/LFT...20-24Z FOR AEX...22-02Z FOR LCH...AND 23-03Z FOR BPT...IF AREA HOLDS TOGETHER THIS EVENING AS THE NAM12 & HRRR SUGGESTS. LATER THIS EVENING...REMAINING INSTABILITY MAY KEEP VCSH OVERNIGHT INTO WED MORNING. DML && .PREV DISCUSSION... /ISSUED 958 AM CDT TUE JUN 9 2015/ UPDATE... WILL BE UPDATING TO INCREASE THE RAIN CHANCES ACROSS MAINLY SOUTH CENTRAL LOUISIANA THIS AFTERNOON. OUTFLOW BOUNDARIES COMBINED WITH SEA BREEZE AND UPPER LEVEL SHORT WAVE SHOULD AID IN THE INITIATION OF ADDITIONAL SHOWERS AND THUNDERSTORMS OVER THE AREA THIS AFTERNOON. ALSO COOLED TEMPERATURES WITH RAIN COOLED AIR AS WELL. PREV DISCUSSION... /ISSUED 645 AM CDT TUE JUN 9 2015/ DISCUSSION... 09/12Z TAF ISSUANCE. AVIATION... A FEW SHRA/TSRA BEGINNING TO DEVELOP NR THE COAST EARLY THIS MORNING WHILE FURTHER NORTH...ISLTD TO SCT CONVECTION HAS BEEN DEVELOPING/MOVING SOUTH AS ENERGY ASSOCIATED WITH A MID AND UPR LVL TROF MOVES INTO THE AREA. SCT SHOWERS AND TSTMS EXPECTED TO DEVELOP WITH DAYTIME HEATING AS THE WEAK SHORTWAVE MOVES ACRS THE AREA...WITH COVERAGE EXPECTED TO BE A LITTLE BETTER THAN YESTERDAY MAINLY NR THE LA TERMINALS. THE PROXIMITY OF THE UPPER RIDGE TO SE TX SHOULD KEEP CONVECTION MORE ISLTD NR BPT. OTHERWISE...VFR CONDITIONS SHOULD PREVAIL WITH LT SWLY WINDS. CONVECTION EXPECTED TO DIMINISH AFTER SUNSET WITH SCT/BKN MID AND HIGH CLOUDS OVERNIGHT. 24 PREV DISCUSSION... /ISSUED 428 AM CDT TUE JUN 9 2015/ SYNOPSIS... LATEST ANALYSIS SHOWS AN UPPER LEVEL RIDGE CENTERED OVER NORTHERN OLD MEXICO...WITH AN UPPER LEVEL TROUGH EXTENDING FROM THE EASTERN GREAT LAKES INTO THE SOUTHERN PLAINS MOVING TO THE SOUTHEAST. A SURFACE REFLECTION OF THIS FEATURE IS NOTED FROM ROUGHLY THE ARKLATEX TO THE OHIO VALLEY AND BECOMING QUASI-STATIONARY...AS THE UPPER LEVEL SUPPORT MOVES OFF TO THE NORTHEAST. 50H HEIGHTS ARE SLIGHTLY LOWER FOR KLCH AS THE UPPER LEVEL TROUGH IS HELPING TO WEAKEN AND SHIFT THE UPPER LEVEL RIDGE TO THE WEST. REALLY GOOD MOISTURE WAS NOTED ON THE 09/00Z UPPER AIR SOUNDING...WITH PWAT OVER 2 INCHES AND MEAN RH OVER 70 PERCENT. HOWEVER...SINCE THEN GPS-MET INTEGRATED PWAT AND SATELLITE BLENDED TOTAL PWAT SHOWS VALUES LOWER AND IN THE 1.8 RANGE...STILL ABOVE THE JUNE NORM. ONE OTHER NOTE...THE SATELLITE BLENDED TOTAL PWAT STILL SHOWS A LARGE POOL OF TROPICAL MOISTURE IN THE NORTHWEST CARIBBEAN WITH PWAT VALUES BETWEEN 2.1 AND 2.5 INCHES. RUA DISCUSSION... IN THE SHORT TERM...UPPER LEVEL RIDGE WILL CONTINUE TO LOSE ITS GRIP AND SHORT WAVE TROUGH MOVES OFF TO THE EAST. THIS WILL LEAVE BEHIND A NORTHERLY CONTINENTAL FLOW IN THE MID TO UPPER LEVELS. THIS WILL KEEP THE DEEP TROPICAL MOISTURE CUT OFF FROM THE FORECAST AREA. STILL...LIGHT SOUTHERLY WINDS IN THE LOW LEVELS WILL PROVIDE ENOUGH MOISTURE...WITH PRECIPITABLE WATER VALUES AROUND TO JUST ABOVE SEASONAL NORMS...AND RANGING FROM 1.6 TO 1.75 INCHES WITH MEAN RH IN THE 50 TO 60 PERCENT RANGE. ALSO...WITH THE NORTHERLY FLOW IN THE MID LEVELS...THIS WILL LIKELY KEEP SEA BREEZE CONFINED CLOSER TO THE COAST AND THE SOUTHERN ZONES. LOOKS LIKE TYPICAL DAYTIME HEATING TYPE CONVECTION OVER THE NEXT FEW DAYS AND WILL KEEP POPS IN THE CHANCE RANGE...WITH THE BEST CHANCE FOR ACTIVITY NEAR MESO SCALE BOUNDARIES...SEA BREEZE/OUTFLOWS/ATCHAFALAYA BASIN CONVERGENCE. THROUGH THURSDAY...THE BEST TIME TO SEE THE CONVECTION WILL BE LATE MORNING THROUGH THE AFTERNOON. WEAK SHEAR AND MODERATE INSTABILITY SO DO NOT EXPECT ALOT OF STRONG ACTIVITY...MAY BE JUST A COUPLE OF PULSE TYPE STORMS IF BOUNDARY CONVERGENCE TAKES PLACE THAT COULD PRODUCE SOME GUSTY WINDS. HOWEVER...SLOW MOVEMENT OF STORMS MAY PRODUCE BRIEF HEAVY RAINFALL. IN THE LONG TERM...A WEAK MID LEVEL DISTURBANCE WILL DEVELOP OVER THE SOUTHEAST U.S. AND EASTERN GULF BY WEDNESDAY/THURSDAY. THE SUBTROPICAL RIDGE OFF OF FLORIDA WILL EXPAND WESTWARD...PUSHING THIS WEAKNESS TO THE WEST AND BE SOUTH OF THE FORECAST AREA AND OVER THE WESTERN GULF BY FRIDAY. IN THE MEANTIME...AN UPPER LEVEL TROUGH AND SURFACE FEATURE WILL DEVELOP FROM THE EASTERN ROCKIES DOWN INTO THE SOUTHERN PLAINS. THE INTERACTION OF THESE FEATURES...WILL ALLOW A STRENGTHENING AND DEEPENING OF THE SOUTHERLY FLOW ACROSS THE FORECAST AREA...THAT WILL LIKELY TAP INTO THE TROPICAL MOISTURE OVER THE NORTHWEST CARIBBEAN AND FUNNEL IT UP OVER THE FORECAST AREA. PRECIPITABLE WATER VALUES BY FRIDAY AFTERNOON INCREASE TO BETWEEN 2 AND 2.25 INCHES WITH MEAN RH OVER 80 PERCENT. THIS TROPICAL LIKE AIRMASS WILL STICK AROUND THROUGH THE WEEKEND. AS IS TYPICAL WITH THESE AIR MASSES...WILL NOT TAKE MUCH HEATING TO PRODUCE WIDESPREAD SHOWERS AND THUNDERSTORMS. NOCTURNAL ACTIVITY WILL LIKELY BE ONGOING DURING THE NIGHT OVER THE COASTAL WATERS INTO THE COASTAL AREA...WITH IT EXPANDING NORTHWARD DURING THE MORNING INTO THE AFTERNOON HOURS...BEFORE POSSIBLY DECREASING DURING THE EVENING HOURS...WITH THE PROCESS THEN STARTING OVER DURING THE OVERNIGHT HOURS EACH DAY THROUGH THE WEEKEND. WITH THE HIGH MOISTURE CONTENT...AND EXPECTED ROUNDS OF SHOWERS AND THUNDERSTORMS...SOME LOCALLY HEAVY RAINFALL COULD BE POSSIBLE DURING THIS TIME FRAME. IN THE FAR EXTENDED...SOME DIFFERENCES AS TO WHEN THE PATTERN WILL CHANGE. THE GFS KEEPS THE WEAKNESS AND THE SOUTHERLY FLOW OVER THE FORECAST AREA THROUGH EARLY NEXT WEEK...WITH THE ECMWF BUILDING AND STRENGTHENING AND UPPER LEVEL RIDGE ACROSS THE GULF SOUTH THAT WOULD PUSH THE DEEP MOISTURE TO THE SOUTH AND WEST. AT THE END OF THE FORECAST...WILL STAY CLOSE TO SUPERBLEND WHICH CALLS FOR A GRADUAL DECREASE IN RAIN CHANCES. RUA MARINE... A WEAK PRESSURE PATTERN ACROSS THE COASTAL WATERS HELPING TO PROVIDE LIGHT WINDS AND LOW SEAS AS THE FORECAST PERIOD BEGINS. WEAK SURFACE HIGH WILL RIDGE ACROSS THE NORTHERN GULF OVER THE NEXT FEW DAYS...WITH A SURFACE BOUNDARY WASHING OUT OVER THE LOWER MISSISSIPPI VALLEY...WELL NORTH OF THE COASTAL WATERS. THUS...THE WEAK PRESSURE GRADIENT WILL CONTINUE THROUGH ROUGHLY THURSDAY...WITH LIGHT...MAINLY SOUTHERLY WINDS...AND LOW SEAS. LOW PRESSURE WILL FORM OVER THE EASTERN ROCKIES INTO THE SOUTHERN PLAINS BY FRIDAY. MEANWHILE...THE SURFACE RIDGE OFF THE EAST COAST OF FLORIDA...WILL CONTINUE TO RIDGE WESTWARD ACROSS THE NORTHERN GULF. THE GRADIENT WILL INCREASE BETWEEN THESE TWO FEATURES...WHICH WILL INCREASE THE SOUTHERLY WINDS AND HELP BUILD SEAS. SMALL CRAFT EXERCISE CAUTION MAY BE NEEDED BY EARLY FRIDAY MORNING...WITH SMALL CRAFT EXERCISE CAUTION AND BORDERLINE SMALL CRAFT ADVISORY CONDITIONS CONTINUING INTO SATURDAY. SHOWER AND THUNDERSTORM ACTIVITY WILL BE ON THE INCREASE BY THURSDAY NIGHT...AND PERSIST THROUGH THE WEEKEND...AS A SURGE OF TROPICAL MOISTURE OVERTAKES THE REGION. SOME OF THE STORMS WILL PRODUCE LOCALLY HIGHER WINDS AND SEAS...ALONG WITH OCCASIONAL CLOUD TO WATER LIGHTNING...AND HEAVY RAINFALL REDUCING VISIBILITIES. RUA && .PRELIMINARY POINT TEMPS/POPS...

</html>The Ft Polk radar (KPOE), 102 km away, was scanning. The volume nearest the first event began at 19:10 UTC.
2 thunderstorm wind, 1 hail. Local standard time, as filed.
A teen was waiting in a car for a thunderstorm to pass when a tree was downed onto the vehicle. The teen in the car was pronounced dead at the scene.
A microburst over the Lake Charles Regional Airport produced a wind gust of 74 MPH. No damage was reported.
One inch in diameter hail was reported in Iowa.
As the offices recorded each death: direct deaths were caused by the weather itself, indirect ones by something it set in motion.
