The episode as NWS LOT wrote it up.
Lightning from thunderstorms moving across far northeastern Illinois during the morning of September 19th sparked a fire to a house in Lake Forest.
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 Chicago, IL wrote its last area forecast discussion before the first event at Sep 19, 5:35 AM CST, 1 hour 50 minutes earlier.
AREA FORECAST DISCUSSION NATIONAL WEATHER SERVICE CHICAGO/ROMEOVILLE IL 635 AM CDT THU SEP 19 2013 .DISCUSSION... 338 AM CDT THE FORECAST CHALLENGES ARE CENTERED ON THE NEXT 36 HOURS AS AN UNSEASONABLY WARM AND MOIST AIR MASS FOR LATTER SEPTEMBER IN PLACE WILL KEEP THE POTENTIAL FOR STORMS THROUGH TODAY AND AID IN ACTIVITY ALONG A COLD FRONT MOVING THROUGH LATER TONIGHT AND FRIDAY. THIS MORNING...PESKY MCV IS CENTERED OVER NORTHERN IN THIS MORNING AFTER ITS 18-24 HOUR EASTWARD TRACK OF TROUBLE FROM CENTRAL IA YESTERDAY MORNING. THE STORM ACTIVITY OF YESTERDAY AND LAST NIGHT KEPT THE LOW-LEVEL WARM FRONT FROM DEVELOPING TOO QUICKLY NORTHWARD...SO THAT IS ROUGHLY ANALYZED FROM A 1001MB LOW ACROSS EASTERN SD THROUGH SOUTHERN MN AND INTO THE WESTERN AND SOUTHERN FORECAST AREA. WARM AIR ADVECTION INDUCED ASCENT NORTH OF THIS HAS ONCE AGAIN SPARKED CONVECTION IN THE FAST PACED WSW MID- LEVEL FLOW EARLY THIS MORNING...THIS TIME ACROSS SW WI/NE IA/NW IL. A SUBTLE SHORT WAVE IS NOTED IN WATER VAPOR AND ANALYZED BY HIGH RES MODELS AS WELL. AS THE LOW-LEVEL JET AND ASSOCIATED MOISTURE TRANSPORT VEER EASTWARD THIS MORNING...SOME OF THIS ACTIVITY SHOULD FEED ON INSTABILITY AND TRAVERSE THE FORECAST AREA AHEAD OF THE WAVE. AMDAR SOUNDING FROM ROCKFORD EARLY THIS MORNING SHOWED 1300 J/KG OF ELEVATED CAPE WHEN LIFTING FROM 850MB...SO SOME FUEL THERE FOR STORMS AND POSSIBLY A COUPLE STRONGER ONES CAPABLE OF SMALL HAIL...GUSTY WINDS...AND VERY EFFICIENT RAINFALL. EXPECT THE ACTIVITY TO MOVE MAINLY EAST OF THE FORECAST AREA BY LATE MORNING/EARLY AFTERNOON WITH WARM AIR ADVECTION CLOUDS SCATTERING. THIS AFTERNOON...THE THERMAL RIDGE AHEAD OF THE SYSTEM COLD FRONT DEVELOPS NORTHEAST OVER THE AREA THIS PERIOD AND IS ROBUST FOR THIS TIME OF YEAR...WITH 850MB TEMPERATURES OF 18C-20C FROM EAST TO WEST ACROSS THE CWA. LOCAL CLIMATOLOGY SUPPORTS HIGHS AROUND 90...OR IN OTHER WORDS WITHIN 5F OF RECORD HIGHS FOR TODAY. SOME OF THE MORNING CLOUDS...ESPECIALLY ACROSS THE NORTHEAST FORECAST AREA WHERE THEY MAY LAST THE LONGEST...WILL HINDER THAT SOME. OTHERWISE GOING FORECAST HIGHS CONTINUE TO LOOK GOOD AND ARE SUPPORTED BY SOME OF THE BEST VERIFYING GUIDANCE ON WARM DAYS WITHIN THIS PAST MONTH. IF STORMS FESTER FOR LONGER THIS MORNING AND CONTINUE INTO AFTERNOON...THEN GOING FORECAST IS TOO HIGH BY SEVERAL DEGREES. WHILE MLCAPES ARE FORECAST TO BUILD TO 2000-2500 J/KG ACROSS THE CWA LIKELY ERODING CIN BY MID TO LATE AFTERNOON...THE FOCUS OF PRE-FRONTAL CONVERGENCE AND SHORT WAVE ENERGY STILL MAINLY LOOKS TO BE AFTER 00Z. BUT THIS IS A HIGH PWAT WARM SECTOR WITH LIMITED CAPPING AND AS YESTERDAY SHOWED...EVEN SOMETHING SUBTLE CAN CAUSE PROBLEMS. SO START INCHING UP POPS IN THE WESTERN CWA LATE THIS AFTERNOON. IF STORMS CAN MAKE IT IN THAT EARLY...SCATTERED SEVERE POTENTIAL IS THERE GIVEN JUST THE INSTABILITY AND PWATS. TONIGHT AND FRIDAY...THE SURFACE LOW WILL DEVELOP NORTHEASTWARD INTO ONTARIO TONIGHT STEERING THE COLD FRONT INTO THE WESTERN FORECAST AREA LIKELY BY AROUND DAYBREAK FRIDAY. FOCUS FOR CONVECTION REMAINS GOOD...ESPECIALLY FOR THE WESTERN FORECAST AREA THIS EVE INTO EARLY OVERNIGHT. A SCATTERED SEVERE THREAT EXISTS EVEN WITH MARGINAL DEEP LAYER SHEAR. MUCH LIKE YESTERDAY...THE THREATS FROM LIKELY MULTI-CELL OR SOMEWHAT LINEAR ACTIVITY THAT COULD REACH SEVERE LIMITS WOULD BE VERY HEAVY RAINFALL...GUSTY WINDS...AND HAIL. SOME INDICATION IN BOTH THE 19.00 NAM AND GFS THAT THE BEST DEEP CONVERGENCE SORT OF SPLITS THE EASTERN FORECAST AREA AS THE BOUNDARY ADVANCES...AND SEVERAL CONVECTIVE ALLOWING GUIDANCE MEMBERS DO SHOW A GENERAL DECREASE IN REFLECTIVITY INTO THE OVERNIGHT. THINK THAT MAY BE A LITTLE TOO EAGER TO DIMINISH CONVECTION GIVEN THE PWATS AT TWO STANDARD DEVIATIONS ABOVE NORMAL AND A WELL-DEFINED COLD FRONT MOVING INTO THAT AIR MASS. SO STILL HAVE MAINTAINED HIGH POPS EVEN FURTHER EAST LATE INTO THE NIGHT AND INTO FRIDAY MORNING. DID ADD MENTION OF HEAVY RAIN IN THE WESTERN FORECAST AREA GIVEN THE HIGH LIKELIHOOD OF RAIN IN A MOIST AND REPLENISHING AIR MASS. THANKFULLY THAT AREA DID NOT RECEIVE THE HIGHER RAIN YESTERDAY. A REGENERATION OF STRONGER CONVECTION ON FRIDAY LOOKS POSSIBLE...BUT MAINLY EAST OF THE FORECAST AREA ON THE MEAN OF MODEL GUIDANCE. COULD SEE A LITTLE SLOW DOWN AGAIN...BUT AT THIS POINT NOT TOO CONCERNED ON A SEVERE THREAT FRIDAY IN OUR CWA. MORE SO IT WOULD STILL BE THE HEAVY RAIN POTENTIAL. MILD TEMPERATURES TONIGHT LOOK TO CLIMB TO THE MID 70S TO 80 ON FRIDAY AS THE COLD AIR ADVECTION ENSUES ALOFT. SATURDAY AND BEYOND...GIVEN ACTIVE SHORT TERM WEATHER HAVE GONE WITH A SMART CONSENSUS BLEND DURING THIS TIME. WITH 850MB TEMPERATURES FORECAST BY THE NAM/GFS/EC OF 3C-5C OVER LAKE MI...SOME LAKE EFFECT CLOUDS ARE LIKELY SATURDAY NIGHT INTO EARLY SUNDAY INTO NW IN/NE IL AS THE WINDS VEER NNE OVER THE LAKE. OVER LAND SATURDAY NIGHT CONDITIONS SHOULD BE CLOSER TO CALM. SO THAT SPELLS WHAT COULD BE QUITE AN IMPRESSIVE TEMPERATURE CONTRAST ACROSS CHICAGOLAND AND HAVE THAT AT ALMOST 20F IN THE FORECAST SUNDAY MORNING...WITH LOWS AROUND 39F IN AURORA WHILE 58F DOWNTOWN CHICAGO. THE SURFACE HIGH MOVES EASTWARD EARLY NEXT WEEK WITH VERY GRADUALLY DEVELOPING WARM AIR ADVECTION. TEMPERATURES ARE FORECAST TO INCH UP A COUPLE DEGREES EACH DAY. MTF && .AVIATION... //ORD AND MDW CONCERNS...UPDATED 12Z... * SCATTERED SHRA/TSRA DURG THE MORNING HOURS. CIGS/VIS OCNLLY LOWERING TO IFR OR LOWER END MVFR. * ANOTHER ROUND OF SHRA/TSRA POSSIBLE LATE TONIGHT WITH COLD FRONT PASSAGE. * SLY-SSWLY WINDS GUSTING TO 20-25KT FROM LATE MORNING TO EARLY EVENING...SHIFTING TO NWLY LATE MORNING OR EARLY AFTERNOON TOMORROW. KREIN //DISCUSSION...UPDATED 12Z... PRIMARY CONCERNS THROUGH THE PERIOD WILL BE PERIODIC CHANCES FOR ADDITIONAL SHRA/TSRA AND SLY-SSWLY WINDS GUSTING TO 20-25 KT. THE REGION REMAINS UNDER WARM/MOIST ADVECTION WITH SLY FLOW AT THE SFC AND SWLY FLOW THROUGH THE LOWEST 10KFT ABOVE THE SFC LAYER. WHILE THE STRONGEST WARM ADVECTION AND ISENTROPIC LIFT REMAINS TO THE WEST...OVER THE UPPER MISSOURI VALLEY TO THE MIDDLE MISSISSIPPI VALLEY. THE BROAD AREA OF WARM ADVECTION AND LIFT WILL KEEP THE CHANCES FOR SCT THUNDER OVER THE AREA FOR THE NEXT FEW HOURS...HOWEVER...GIVED THE LACK OF A SPECIFIC FOCUSING MECHANISM...THE ACTIVITY WILL BE SCATTERED AND LIKELY WILL NOT IMPACT THE TERMINALS FOR A SOLID BLOCK OF TIME. SO...WILL KEEP THE VCSH AND TEMPO GROUPS IN THE FORECAST...BUT CONFIDENCE REMAINS LOW AS TO THE EXACT TIMING OF DIRECT IMPACT ON THE TERMINALS. THE OTHER SIGNIFICANT CHANCE FOR THUNDER WILL COME THIS EVENING AND THROUGH THE NIGHT AS A COLD FRONT MOVES THROUGH THE REGION. FOR THE EVENING HOURS...THE ACTIVITY...ONCE AGAIN...WILL LIKELY BE MORE SCATTERED...BUT AS THE COLD FRONT APPROACHES...THE ACTIVITY SHOULD SOLIDIFY WITH A PERIOD OF PREVAILING THUNDER LIKELY. AT THIS POINT...THE BEST CHANCE FOR PREVAILING THUNDER SHOULD BE JUST AFTER MIDNIGHT AND INTO THE EARLY MORNING HOURS. THERE SHOULD THEN BE A PERIOD OF SOME TRAILING STRATIFORM RAIN WITH LOWER END MVFR OR POSSIBLY IFR CIGS DEVELOPING FOR THE PRE-DAWN HOURS. FOR WINDS...THERE IS LITTLE CHANGE TO THE GOING FORECAST. WINDS SHOULD REMAIN SLY THROUGH THE MORNING AT ARND 10KT...AWAY FROM THUNDER. SOME LOCALLY HIGHER GUSTS ARE POSSIBLY INVOF THUNDER. WITH DAYTIME WARMING AND SOME BREAKING UP OF CLOUD COVER...HIGHER GUSTS SHOULD MIX DOWN TO THE SFC AND FREQUENT GUSTS TO ARND 20KT SHOULD PREVAIL FROM LATE MORNING THROUGH EARLY EVENING. AS THE FRONTAL TROUGH APPROACHES THE MISSISSIPPI RIVER LATER TODAY...WIND DIRECTION SHOULD VEER A LITTLE WEST OF SOUTH TO 200-210 DEGREES BEFORE SHIFTING TO NWLY WITH THE FROPA. KREIN //ORD AND MDW CONFIDENCE...UPDATED 12Z... * LOW CONFIDENCE IN TIMING AND COVERAGE OF TSRA THIS MORNING. * HIGHER CONFIDENCE IN TSRA PROBABILITY AND COVERAGE LATE TONIGHT. * MEDIUM TO HIGH CONFIDENCE IN WIND TRENDS. * MEDIUM CONFIDENCE IN CIG TRENDS.

KREIN && .MARINE... 300 AM CDT AN AREA OF LOW PRESSURE CENTERED OVER THE EASTERN DAKOTAS WILL WEAKEN SLIGHTLY AND TRACK NORTHEAST TO WESTERN ONTARIO BY THIS EVENING. SOUTHERLY WINDS TO AROUND 25 KT WILL PERSIST OVER THE LAKE AS THE THE LOW DEEPEN FURTHER AND TRACKS NORTHEAST INTO NORTHERN QUEBEC BY SATURDAY MORNING. AN ASSOCIATED COLD FRONT WILL SWEEP ACROSS LAKE MICHIGAN FRIDAY AFTERNOON AND EVENING...WITH WINDS GRADUALLY VEERING FROM SOUTHWESTERLY TO NORTHWESTERLY AND...ULTIMATELY NORTHEASTERLY...AS A LARGE AREA OF HIGH PRESSURE BUILDS IN BEHIND THE FRONT.

THE OVERALL BEST CHANCE TODAY TO SEE SEVERE WEATHER WILL ALSO BE THIS EVENING INTO EARLY OVERNIGHT ACROSS NORTH CENTRAL ILLINOIS.
