The episode as NWS MKX wrote it up.
Scattered thunderstorms produced lightning during the afternoon hours of April 9th and again during the early morning hours of April 10th, igniting 3 separate house fires. The lightning also stuck power lines that caused power outages affecting about 6300 customers in the Milwaukee metropolitan area. The thunderstorms fired up as a low-level jet impinged along an 850 mb baroclinic zone that set up over the area ahead of a 500 mb short-wave, with additional forcing for deep vertical motions provided by a nearly-coupled upper jet.
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 Milwaukee, WI wrote its last area forecast discussion before the first event at Apr 9, 10:47 AM CST, 2 hours 3 minutes earlier.
AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE MILWAUKEE/SULLIVAN WI
1147 AM CDT TUE APR 9 2013
.UPDATE...
LAST OF THE SHOWERS/STORMS FROM THIS MORNING WILL SHIFT EAST
NORTHEAST OUT OF THE AREA IN THE NEXT HOUR OR TWO. NEXT LINE OF
SHOWERS AND STORMS MOVING EAST NORTHEAST FROM NORTHEAST IOWA INTO
THE AREA THIS AFTERNOON. THESE SHOULD LAST FOR AN HOUR OR TWO...AS
THEY MOVE THROUGH THE AREA.
THESE AREAS OF PRECIPITATION CONTINUE TO FORM ON 850MB
CONVERGENCE/FRONTOGENESIS RESPONSE SPREADING WEST TO EAST ACROSS
THE AREA. AREA OF SHOWERS/STORMS MOVING THROUGH THE AREA THIS
AFTERNOON HELPED ALONG AS WELL BY 500MB SHORTWAVE TROUGH. SOME OF
THE STORMS MAY PRODUCE SMALL HAIL...GIVEN WEAK ELEVATED CAPE AND
STRONG DEEP LAYER SHEAR.
FLOOD WATCH CONTINUES ACROSS THE AREA INTO FRIDAY...AS ROUNDS OF
RAIN ARE EXPECTED...AND SHOULD PRODUCE 2 TO 3 INCHES TOTAL
RAINFALL DURING THIS TIME. SEE FLOOD WATCH PRODUCT FOR MORE
INFORMATION.
NORTHEAST WINDS WILL GRADUALLY INCREASE THIS AFTERNOON. THE
WINDS...ALONG WITH CLOUDS AND PRECIPITATION...WILL LIMIT
TEMPERATURE RISE ACROSS THE AREA. KEPT TEMPERATURES NEAR CURRENT
VALUES THROUGH THE REST OF TODAY.
&&
.AVIATION/18Z TAFS/...
CURRENT SHOWER/STORM ACTIVITY WILL EXIT EASTERN TAF SITES OVER THE
NEXT HOUR OR TWO. NEXT ROUND OF SHOWERS/STORMS WILL SHIFT EAST
NORTHEAST THROUGH TAF SITES THIS AFTERNOON. EXPECT CEILINGS AND
VISIBILITIES AROUND ALTERNATE MINIMUMS DURING THIS TIME...WITH
AIRPORT MINIMUMS POSSIBLY BEING REACHED WITHIN ANY STORMS. SMALL
HAIL IS POSSIBLE WITH ANY OF THE STORMS. NORTHEAST WINDS WILL
INCREASE IN MAGNITUDE THIS AFTERNOON...BECOMING GUSTY LATE IN THE
DAY.
EXPECT ROUNDS OF RAIN WITH A FEW THUNDERSTORMS TO OCCUR ACROSS TAF
SITES TONIGHT AND WEDNESDAY. GUSTY NORTHEAST WINDS WILL LINGER
ACROSS THE AREA DURING THIS TIME. CEILINGS AND VISIBILITIES WILL
CONTINUE TO BE AROUND ALTERNATE MINIMUMS...WITH VALUES NEAR
AIRPORT MINIMUMS POSSIBLE IN ANY STORMS.
&&
.MARINE...
MARINE DENSE FOG ADVISORY WILL BE CANCELLED ACROSS THE NEARSHORE
WATERS OF LAKE MICHIGAN. AREA WEB CAMERAS ARE SHOWING GREATLY
IMPROVED VISIBILITIES ACROSS THE WATERS. THIS IS IN RESPONSE TO
INCREASING NORTHEAST WINDS ACROSS THE WATERS...WHICH WILL CONTINUE
TO STRENGTHEN THIS AFTERNOON AND LINGER FOR THE NEXT FEW DAYS. DEW
POINTS SHOULD REMAIN AROUND THE LAKE TEMPERATURE DURING THIS
TIME...SO DO NOT EXPECT ANY REFORMATION OF THE DENSE FOG TONIGHT
INTO WEDNESDAY.
SMALL CRAFT ADVISORY REMAINS IN EFFECT STARTING AT 4 PM THIS
AFTERNOON INTO FRIDAY. GUSTY NORTHEAST WINDS WILL DEVELOP LATER
THIS AFTERNOON AND LINGER TONIGHT THROUGH WEDNESDAY NIGHT...AS A
TIGHT PRESSURE GRADIENT DEVELOPS WITH THE APPROACHING LOW PRESSURE
SYSTEM FROM THE SOUTHWEST. WINDS WILL BACK EAST THURSDAY AS THE
LOW PASSES TO THE SOUTHEAST...BEFORE GRADUALLY BACKING TO THE
NORTH AND WEAKENING FRIDAY. THESE WINDS WILL GENERATE HIGH WAVES
ALONG THE SHORE AND IN THE NEARSHORE WATERS INTO FRIDAY.
&&
.PREV DISCUSSION... /ISSUED 329 AM CDT TUE APR 9 2013/
TODAY AND TONIGHT...FORECAST CONFIDENCE...MEDIUM TO HIGH
NUMEROUS ROUNDS OF RAIN WILL HIT THE AREA TODAY AND TONIGHT. THE
FIRST ROUND WILL BE THE ELEVATED ACTIVITY JUST NORTH OF THE SURFACE
STATIONARY FRONT OVER ILLINOIS EARLY THIS MORNING LIFTING NORTH INTO
THE AREA BETWEEN 08-12Z THIS MORNING...BUT WEAKENING SOME AS IT
PUSHES INTO THE COLDER AIR IN THESE PARTS. FOR THIS MORNING...WOULD
EXPECT THE HIGHEST POPS TO REMAIN ACROSS THE SOUTH. THE CONVECTION
OUT ACROSS NEBRASKA EARLY THIS MORNING IS EXPECTED TO THEN REACH
WISCONSIN THIS AFTERNOON. THE NAM DOESN/T APPEAR TO BE HANDLING THIS
VERY WELL FROM THE START...SO WILL FOLLOW THE STRONGER CONSENSUS
THAT BRINGS THIS RIGHT ACROSS THE FORECAST AREA THIS AFTERNOON.
THIS IS THE SWEET SPOT BETWEEN THE SFC AND H8 FRONTAL POSITIONS. A
PERSISTENT PATTERN OF DEEP UPWARD VERTICAL MOTION FROM A NEARLY
COUPLED JET WILL CONSPIRE WITH A LOWER LEVEL BAROCLINIC ZONE FOR A
FAVORABLE SET UP LEADING TO COPIOUS RAINFALL. THE GENESIS OF OUR
PERIODIC RAIN WILL START UPSTREAM IN THE PLAINS...THEN MOVE EAST
ACROSS OUR AREA.
FOG IS A PROBLEM IN THE EAST THIS MORNING DUE TO THE COLD FLOW OFF
THE LAKE. THE RAIN SHOULD HELP TO SCOUR THIS OUT...BUT IT COULD BE
PROBLEMATIC OVER THE NEXT FEW DAYS AS THE PATTERN WON/T CHANGE MUCH.
WEDNESDAY AND WEDNESDAY NIGHT - CONFIDENCE...MEDIUM
UNSETTLED PERIOD WILL CONTINUE WITH LARGE UPPER TROUGH IN THE
CENTRAL PLAINS. SURFACE LOW REMAINS TO OUR SOUTH ALONG WITH THE
SURFACE BOUNDARY. 850 FORCING VIA LOW LEVEL JET AXIS IMPINGING ON
BAROCLINIC ZONE WILL KEEP PRECIP RAIN GOING. NE WINDS WILL KEEP
THINGS QUITE CHILLY OFF THE COLDER WATERS OF LAKE MICHIGAN. MODELS
SUGGEST A RELATIVE LULL FROM LATE MORNING INTO THE AFTERNOON WITH
ANOTHER ROUND WEDNESDAY NIGHT. ELONGATED 850 CIRCULATION SLOWLY
TRANSLATES EAST FROM IOWA TO NEAR THE WI/IL BORDER WEDNESDAY NIGHT.
THURSDAY AND THURSDAY NIGHT - CONFIDENCE...MEDIUM
UPPER LOW TRACKS FROM KS/NEB BORDER TO SRN WI THURSDAY NIGHT. 12Z
ECMWF MOST AGGRESSIVE WITH NORTHWESTWARD EXTENT OF WARMER AIR WHILE
THE 00Z GFS AND ESPECIALLY THE 00Z NAM COOL 850 TEMPS TO CRITICAL
LEVELS WITH RESPECT TO PRECIPITATION TYPE. AT THIS POINT 00Z GFS IS
A THERMAL COMPROMISE BETWEEN 12Z ECMWF AND 00Z NAM. CURRENT FORECAST
GRADUALLY BRINGS A MIX A BIT DEEPER INTO SC WI THURSDAY WITH TIME
WITH POTENTIAL FOR PURE SNOW IN THE NW CWA. THIS STILL APPEARS
REASONABLE. WILL KEEP ANY ACCUMS CONFINED TO THE FAR NW CWA...THIS
WHERE COLDEST TEMPS LIKELY. COLD ADVECTION KICKS IN CWA WIDE
THURSDAY NIGHT. WILL BOOST POPS A BIT. SOME ADDITIONAL ACCUMS
POSSIBLE A BIT FURTHER EAST AND SOUTH ACROSS THE CWA AS THE COLDER
AIR WRAPS IN WITH THE LOW OFF TO THE EAST.
FRIDAY - CONFIDENCE...MEDIUM
LINGERING CYCLONIC CURVATURE INTO THE EVENING. CHILLY FLOW WITH 850
THERMAL TROUGH ACROSS THE AREA. 850 TEMPS FROM -6 TO -8C. WILL HAVE
TO INCLUDE A CHANCE OF SNOW SHOWERS. SOUNDINGS NOT SUPPORTIVE OF
WARMING THE LOW LAYERS ENOUGH TO PRECLUDE THIS POTENTIAL.
SATURDAY - CONFIDENCE...LOW
THOUGH SOME VARIATIONS IN THE PLACEMENT OF SYNOPTIC FEATURES THE
CONSENSUS IS TO GO ALONG WITH THE DRY ALLBLEND POPS AT THIS POINT.
SURFACE/850 RIDGING TO SOME DEGREE HIGH PROGGD TO DRAW CLOSER. THE
RETURN WARM ADVECTION MAY RESULT IN SOME PRECIP SATURDAY NIGHT PER
THE GFS AND NOW THE 00Z ECMWF. GIVEN THIS SCENARIO...PLAUSIBLE THAT
THE NORTHERN CWA COULD SEE A MIX GIVEN COLDER THERMAL PROFILE...AT
LEAST AT THE OUTSET.
SUNDAY - CONFIDENCE...MEDIUM
DECENT SURGE OF WAA WITH LLJ NOSE TRANSLATING INTO AND TO THE EAST
OF THE CWA. POTENT LOW PRESSURE TO THE NORTHWEST. GFS CURRENTLY ONLY
SHOWING MINIMAL ELEVATED CAPE THOUGH CWASP IN THE LOW 50S CLIPS THE
SE. THUNDER MAY BE WARRANTED AT SOME POINT BUT CONFIDENCE TOO LOW
FOR INCLUSION ATTM. TRAILING COLD FRONT PASSES SUNDAY EVENING.
MONDAY - CONFIDENCE...MEDIUM
UPPER FLOW BECOMES BROADLY ANTICYCLONIC AS ELONGATED VORT/SHEAR
ZONE LIFTS NORTH. ECMWF SHOWING A BIT MORE COLD AIR ADVECTION THAN
THE GFS.
AVIATION/12Z TAFS/...WIDESPREAD IFR CIGS/VSBYS EXPECTED THROUGH THE
PERIOD. COOL AIR FLOWING IN OFF LAKE MICHIGAN WILL COMBINE WITH
MOISTURE RIDING NORTH OF A STATIONARY FRONT TO OUR SOUTH...RESULTING
IN VERY LOW CIGS. RAIN AND FOG WILL BRING VARIABLE...MOSTLY IFR
VSBYS...THROUGH THE PERIOD.
MARINE...BREEZY NORTH TO NORTHEAST WINDS ARE EXPECTED TODAY THROUGH
FRIDAY...BUILDING HIGH WAVES ACROSS THE NEARSHORE WATERS. A SMALL
CRAFT ADVISORY FROM TODAY THROUGH FRIDAY...AS HIGHER WAVES WILL
LINGER LATER INTO FRIDAY.
