The episode as NWS DLH wrote it up.
Lightning struck a tree near a house at 4382 Martin Road in Duluth, MN. The tree caught fire and caused the fire to spread to the house's attic. There were no injuries as the house was unoccupied.
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 Duluth, MN wrote its last area forecast discussion before the first event at Sep 2, 5:50 AM CST, 2 hours 30 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE DULUTH MN 650 AM CDT WED SEP 2 2015 .SHORT TERM...(TODAY THROUGH THURSDAY) ISSUED AT 423 AM CDT WED SEP 2 2015 A SHORTWAVE TROUGH OVER SOUTHERN MINNESOTA WILL LIFT TO THE NE THIS MORNING...MOVING INTO CENTRAL AND THEN EAST CENTRAL MINNESOTA. THE UPPER LEVEL DIVERGENCE AHEAD OF THIS APPROACHING TROUGH IS HELPING TO DEVELOP SOME ISOLATED/SCATTERED THUNDERSTORMS AND WIDESPREAD LIGHT/MODERATE RAIN...WHICH WAS PRIMARILY AFFECTING THE SOUTHERN FORECAST AREA AND AREAS TO THE SOUTH AS OF WRITING THIS DISCUSSION. THE ENVIRONMENT DOES NOT FAVOR SEVERE WEATHER THIS MORNING. WHILE MUCAPE WILL BE AS HIGH AS 2500 J/KG...DEEP LAYER WIND SHEAR IS RELATIVELY WEAK AND FREEZING LEVELS ARE RELATIVELY HIGH AT BETWEEN 13 AND 14 KFT. ALSO...THE ENVIRONMENT IS RELATIVELY HUMID...SO ANY HAIL WILL BE LIMITED BY MELTING. CANNOT RULE OUT THE POTENTIAL FOR ISOLATED STORMS CAPABLE OF PRODUCING SMALL HAIL. RAINFALL COULD BE HEAVY AT TIMES CONSIDERING PRECIPITABLE WATER VALUES WILL INCREASE TO 1.75 TO 2 INCHES. THERE WILL BE A LOW THREAT OF FLOODING EARLY THIS MORNING DEPENDING ON THE TRAINING OF ANY STORMS. LEANED ON THE RAP13 THROUGH THIS MORNING SINCE IT WAS HANDLING THE LATEST RADAR TRENDS MUCH BETTER THAN OTHER MODELS. THERE WILL BE WARM SOUTHERLY FLOW ACROSS THE NORTHERN PLAINS AND WESTERN GREAT LAKES REGION TODAY WITH AN UPPER LEVEL RIDGE BUILDING IN THE PLAINS. THE TROUGH WILL CONTINUING MOVING THROUGH THE REGION...CUTTING ACROSS WEST CENTRAL AND NW WISCONSIN THIS AFTERNOON AND EVENING. THE SE FORECAST WILL GET RAIN AND THUNDERSTORMS AS THIS TROUGH MOVES THROUGH THE AREA. THE TROUGH WILL ALSO KEEP THE SE FORECAST CLOUDIER TODAY...SO LOWERED HIGH TEMPERATURES A BIT FOR THIS AREA. THE NORTHERN AND WESTERN FORECAST AREA SHOULD SEE SOME CLEARING. IT MAY TAKE LONGER NEAR LAKE SUPERIOR TO SEE CLEARING DUE TO THE HIGHER HUMIDITY FROM THE THE COOL EASTERLY FLOW FROM THE LAKE. HIGHS SHOULD RANGE FROM THE 70S NEAR LAKE SUPERIOR TO THE LOW TO MIDDLE 80S WELL INLAND. THE UPPER LEVEL RIDGE OVER THE NORTHERN PLAINS WILL AMPLIFY AND BUILD INTO THE MINNESOTA/WISCONSIN REGION TONIGHT. THE UPPER LEVEL RIDGE WILL HELP TO CLEAR OUT ANY REMAINING CLOUD COVER FROM THE PASSING TROUGH...AND THE CLEARING WILL PROMOTE RADIATIONAL COOLING AND THE FORMATION OF A NOCTURNAL INVERSION. THE WINDS WILL BE VERY LIGHT. THE MODELS...INCLUDING THE NAM12 AND NAM/GFS MOS...ARE INDICATING A SOLID POTENTIAL FOR FOG TONIGHT. THE NAM12 SURFACE CONDENSATION PRESSURE DEFICITS INDICATE THE COOL AND HUMID EASTERLY FLOW FROM LAKE SUPERIOR WILL HELP TO SATURATE THE BOUNDARY LAYER OVERNIGHT...SO THINK THE RISK OF FOG IS GREATEST NEAR LAKE SUPERIOR. EXPANDED THE FOG IN THE FORECAST COMPARED TO THE PREVIOUS FORECAST. THE UPPER LEVEL RIDGE WILL BE OVER THE NORTHLAND THURSDAY...AND VERY WARM 850 HPA TEMPERATURES OF 20 TO 25 DEGREES CELSIUS WILL MOVE INTO THE AREA WITH THE SOUTHERLY FLOW. THE RIDGE WILL HELP TO KEEP THE NORTHLAND SUNNY...ALTHOUGH THERE COULD BE LINGERING FOG AND LOW STRATUS NEAR LAKE SUPERIOR DUE TO THE COOL EASTERLY FLOW FROM THE LAKE. AREAS NEAR LAKE SUPERIOR SHOULD GET AS HIGHS AS THE UPPER 60S TO MIDDLE 70S...BUT LOW TO MIDDLE 80S ARE EXPECTED WELL INLAND. .LONG TERM...(THURSDAY NIGHT THROUGH TUESDAY) ISSUED AT 423 AM CDT WED SEP 2 2015 HOT AND HUMID WEATHER THROUGH THE WEEKEND WITH A COLD FRONT TO BRING ABOUT MUCH COOLER AND COMFORTABLE WEATHER NEXT WEEK. STILL LOOKS LIKE GOOD CHANCES FOR RAIN...BUT CHANGES IN MODEL TRENDS ARE RESULTING IN ADJUSTMENTS IN THE TIMING FOR THE BEST CHANCE OF RAIN. ON THE SYNOPTIC SCALE THE LONGWAVE TROUGH DEEPENING OVER THE WEST COAST HAS BEEN TRENDING DEEPER OVER THE PAST FEW MODEL SUITES...AS WELL AS A MARKED STRENGTHENING OF THE RIDGE THAT WILL BE CENTERED OVER THE GREAT LAKES REGION. THIS AMPLIFICATION TREND WILL IMPACT THE TIMING OF THE BEST CHANCES FOR PRECIPITATION...AND COULD RESULT IN A MORE POTENT AND ORGANIZED SYSTEM BY THE TIME THE MAIN UPPER LOW/SHORTWAVE TROUGH IMPACTS THE REGION. ONCE THIS LOW CLEARS THE REGION LATE MONDAY INTO TUESDAY MUCH COOLER AIR WILL ADVECT IN FROM THE WEST/NORTHWEST RESULTING IN A RETURN TO SEASONABLE IF NOT BELOW NORMAL TEMPERATURES. THURS NIGHT...ADDED SOME LOW POPS INTO PARTS OF NORTHWEST WISCONSIN ALONG THE U.P. DUE TO ELEVATED INSTABILITY AND THE POSSIBILITY FOR SOME WEAK LARGE SCALE LIFT WITH A PASSING MID- LEVEL WAVE. THE GFS/GEFS HAS BEEN TRENDING TOWARDS INTRODUCING QPF IN THIS AREA WHILE THE ECMWF/EPS /ECMWF ENSEMBLE/ REMAINS DRY. OTHERWISE MOSTLY CLEAR SKIES ACROSS NORTHEAST MINNESOTA INTO ADJACENT AREAS OF NW WISCONSIN WITH TEMPS FALLING TO THE UPPER 50S IN THE MN ARROWHEAD AND SOME PATCHY FOG ALONG THE NORTH SHORE AND ACROSS PARTS OF NORTHWEST WISCONSIN. FRIDAY AND FRIDAY NIGHT...GROSS. HIGHS IN THE LOW TO MID 80S AND DEW POINTS IN THE...70S...UGH. THIS WOULD BE PRETTY HUMID FOR MID- SUMMER LET ALONE LATE SUMMER/EARLY FALL FOR THE NORTHLAND. NOT AT ALL OUT OF THE ORDINARY FOR THIS LATE-SEASON WARMTH...BUT THAT DOES NOT MAKE IT ANY LESS STICKY-FEELING OUTSIDE. AT THE SURFACE A BROAD AREA OF LEE LOW PRESSURE DEVELOPS IN THE NORTHERN PLAINS INTO SOUTHERN MANITOBA WITH A FRONT BEGINNING TO SHARPEN UP IN THIS REGION. AHEAD OF THE FRONT WINDS WILL BE BREEZY OUT OF THE SOUTH TO SOUTH- SOUTHEAST WITH GUSTS TO 20-30 MPH...WITH THE STRONGEST WINDS ACROSS NORTHEAST MINNESOTA. INCREASING CLOUDS ACROSS NORTH-CENTRAL TO NORTHEAST MINNESOTA WITH A CHANCE OF SHOWERS AND STORMS. SATURDAY...A BREAK IN THE STORMS DURING THE DAY DUE TO SOME WEAK SHORTWAVE RIDING ALOFT. STILL WARM AND HUMID WITH SIMILAR TEMPS/DEW POINTS AS FRIDAY. STORMS COULD CONTINUE TO FIRE OFF OF OUTFLOW BOUNDARIES AS WELL AS A WEAK FRONT WHICH SHOULD BE SOMEWHERE OVER NORTHERN BY MINNESOTA DURING THE DAY. WEAK WINDS ALOFT INDICATE INDIVIDUAL STORMS WILL NOT LAST LONG AND IT SHOULD NOT BE RAINING ALL DAY. SATURDAY NIGHT INTO SUNDAY...WILL REMAIN MAINLY IN THE WARM SECTOR WITH CHANCES FOR PRECIP THROUGHOUT SAT NIGHT INTO SUNDAY. LOWS MILD IN THE MID TO UPPER 60S...HIGHS ON SUNDAY IN THE MID 70S TO LOW 80S...WARMEST IN NORTHWEST WISCONSIN. SUNDAY NIGHT INTO MONDAY...POTENTIAL FOR HEAVIEST PRECIP DEPENDING ON PLACEMENT OF THE UPPER LOW THAT EJECTS OUT OF THE PACIFIC NORTHWEST. WHILE CURRENT GUIDANCE HAS THE BEST FORCING OVER THE NORTHERN PLAINS...UPPER MIDWEST DEFINITELY WITHIN THE MARGIN OF ERROR IN THE GUIDANCE AT THIS TIME RANGE. GLOBAL ENSEMBLES STILL AGREE ON THE LIKELIHOOD OF AROUND AN INCH OR MORE OVER THIS TIMEFRAME...BUT THERE IS STILL A LOT OF VARIATION IN THE TIMING OF THE DYNAMICS IN PLAY. REGARDLESS...WILL HAVE A STRONG COLD FRONT MOVING THROUGH DURING THIS TIME FRAME WHICH SHOULD LEAD TO SOME POTENT SHOWERS AND THUNDERSTORMS....AND A CHANCE FOR SOME SHOWERS BEHIND THE FRONT. STORM MOTIONS NORTHEAST AT 35-45 MPH DUE TO THE STRONG WINDS ALOFT MOVING IN. TUESDAY/WEDNESDAY...DRY WITH SEASONABLE TEMPS. BREEZY WEST WINDS BEHIND THE FRONT. HIGHS IN THE UPPER 60S TO LOW 70S...AND LOWS FALLING AS LOW AS THE MID/UPPER 40S INLAND...WARMER BY THE LAKE. && .AVIATION...(FOR THE 12Z TAFS THROUGH 12Z THURSDAY MORNING) ISSUED AT 650 AM CDT WED SEP 2 2015 IN NORTHEAST MINNESOTA A LINE OF STORMS WILL MOVE NORTHEASTWARD AWAY FROM INL/HIB/DLH WITH LINGERING FOG AND THUNDER IN THE VICINITY AT DLH THROUGH MID-MORNING. AT BRD JUST SOME MVFR TO POSSIBLY BRIEFLY IFR VISIBILITY/CEILINGS...BUT THIS WILL ALSO IMPROVE RAPIDLY. IN NORTHWEST WISCONSIN CONDITIONS WILL BE VFR AT HYR RAIN THROUGH THE MORNING WITH OCCASIONAL THUNDER THEN SHOWERS THROUGHOUT MOST OF THE DAY. THIS AFTERNOON...CLEARING SKIES IN NORTHEAST MINNESOTA WHILE SHOWERS AND A FEW STORMS LINGER IN NORTHWEST WISCONSIN. A FEW STORMS MAY IMPACT DLH...BUT CONFIDENCE IS MUCH HIGHER OVER NORTHWEST WISCONSIN. VFR AT ALL SITES WITH LIGHT SOUTHEAST WINDS. TONIGHT...ANOTHER ROUND OF PATCHY FOG/STRATUS DEVELOPING. EXPECTING AT LEAST MVFR CONDITIONS AT MOST TAF SITES WITH IFR CONDITIONS POSSIBLE AT DLH AND HIB TOWARDS EARLY TOMORROW MORNING. WINDS LIGHT TO CALM OVERNIGHT. && .PRELIMINARY POINT TEMPS/POPS...
