The radar

The Northern Indiana radar (KIWX), 30 km from the middle of the area, began a volume at 11:42 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this severe thunderstorm warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

The nearest sounding before it

Detroit, MI (KDTX), launched 00:00Z, 11.6 hours before the alert went out and 213 km from the middle of its area. This is the routine balloon launch nearest before it, the air the forecaster had in hand, not a measurement taken for the alert.

.SHORT TERM...

TODAY THROUGH THUR

ANCHORED UPPER LEVEL RIDGE OVER THE GREAT LAKES WILL REMAIN NEARLY
STATIONARY THROUGH MOST OF THE PERIOD...WITH SOME EASTWARD
PROGRESSION EXPECTED BY LATE IN THE PERIOD AS AN UPPER LOW EJECTS
EAST INTO THE WESTERN MIDWEST. STATIONARY WARM FRONT OVER THE REGION
CONTINUES TO BE THE FOCUS FOR SHOWERS AND THUNDERSTORMS THIS
MORNING. THE SFC REFLECTION OF THIS BOUNDARY HAS SHIFTED BACK SW
INTO THE AREA WITH SUBSTANTIAL DEWPOINT FALLS OVERNIGHT GIVEN A
RATHER POTENT DRY NE TRAJECTORY DRY SURGE PER ANCHORED SFC RIDGE
OVER ONTARIO. REGARDLESS...STORMS SEEM TO BE DEVELOPING ALONG THE
H85 THETA-E GRADIENT AT THE EDGE OF A STAUNCH EML...WITH NW UPPER
FLOW SUPPORTING NUMEROUS SUBTLE IMPULSES INTO WESTERN OH WITH A LL
WAA REGIME. ELEVATED CAPE AROUND 2000 J/KG WILL CONTINUE TO
SUPPORT AN ISOLATED LARGE HAIL THREAT...ESP IF STORMS DEVELOP MID
LEVEL ROTATION WITH MARGINAL DEEP BULK SHEAR NUMBERS.
OTHERWISE...ATTENTION SHIFTS TOWARD AFTERNOON TEMPS AND ADDITIONAL
CHANCES FOR PRECIP. ANOTHER IMPULSE /NOW OVER OK/MO/...IS EXPECTED
INTO THE REGION THIS AFTERNOON. INCREASED MID LEVEL FLOW UPWARDS
OF 50 KNOTS MAY HELP FORCE AFTERNOON CONVECTION. HOWEVER...STRONG
CAPPING IN PLACE EVIDENT IN 00Z DVN AND ILX RAOBS MAY BE TOO
STRONG TO OVERCOME AND WERE POORLY HANDLED IN 00Z NAM AND WRF
DATA. HENCE...HAVE RETAINED LOW CHANCE POPS...WITH HIGHEST NUMBERS
OVER THE NW WHERE STRONGER FORCING LOOKS TO BE. ANOTHER FEATURE TO
WATCH WILL BE THE MCS OVER NORTHERN MI. THIS SYSTEM MAY TURN SE
AND RIDE THE H85 THETA-E GRADIENT SOUTH...POSSIBLY AFFECTING THE
NORTH THIS AFTERNOON AS AN MCV. HAVE CARRIED PRECIP CHANCES
THROUGH THE NIGHT...WITH THE POTENTIAL FOR ANOTHER MCC TRAVERSING
THE EASTERN HALF IF STORMS FIRE THIS AFTERNOON AND ORGANIZE. THIS
POTENTIAL SYSTEM WOULD EVENTUAL TURN SE...TOPPING THE RIDGE
SIMILAR TO THIS MORNING/S CONVECTION...GIVEN THE EXPECTED STALLED
WARM FRONT IN PLACE. IF STORMS DO DEVELOP THIS AFTERNOON...DEEP
MOISTURE IN PLACE WITH A STRONG EML AND STEEP MIDLEVEL LAPSE RATES
WOULD TEND TO FAVOR THE POTENTIAL FOR SEVERE STORMS...WITH 3-4
KJ/KG OF CAPE EXPECTED. SHEAR VALUES WOULD BE MARGINAL THOUGH.
DIURNAL MIXING WILL FAVOR REDISTRIBUTION OF LL MOISTURE AND HEAT
DOWN TO THE THE SFC...WITH TEMPS EXPECTED TO BE WELL INTO THE 80S
AT MOST LOCATIONS/DEWPOINTS IN THE MID TO UPPER 60S...COOLEST
NE...NORTH OF THE SFC WARM FRONT. DEWPOINTS IN THE 60S WITH DEEPLY
MOIST LL PROFILES WILL SUPPORT WARM TEMPS OVERNIGHT...WITH MANY
PLACES SEEING LOWS IN THE MID 60S. WINDS MAY AGAIN BACK TO THE
EAST IN THE FAR EAST AND SUPPORT DRIER AIR BACK INTO THE REGION
ONCE AGAIN...HENCE COOLEST READINGS EXPECTED THERE.

THUR...CLOSED MID LEVEL WAVE WILL SLOWLY ADVECT EAST...SUPPORTING
EVENTUAL HEIGHT FALLS INTO THE REGION. SLOWER EVOLUTION OF THIS
SYSTEM IS EXPECTED TO DELAY BETTER RAIN CHANCES UNTIL LATE THUR OR
EVEN LATER. A DELAY IN BETTER ORGANIZED PRECIP WILL SUPPORT TEMPS
INTO THE 80S ONCE AGAIN FOR MOST OF THE FA...SAVE THE FAR NW WHERE
FLOW OVER LAKE MI WILL QUELL SHARPER T RISES. NO MAJOR CHANGES TO
THIS PERIOD.

&&

.LONG TERM...

CLOSED LOW OVER THE SRN ROCKIES THIS MORNING EXPECTED TO DRIFT EAST
TO MO BY FRIDAY WHILE CLOSED LOW OVER WRN ONTARIO ROTATES SW INTO
THE NRN PLAINS. DIFFUSE CDFNT ASSOCIATED WITH THE LEAD LOW SHOULD
MOVE INTO OUR AREA FRIDAY/FRIDAY NIGHT. AIRMASS SHOULD STILL BE AT
LEAST MODERATELY UNSTABLE AHEAD OF THE FRONT, SO POTENTIAL REMAINS
FOR TSTMS AS THE CDFNT MOVES THROUGH... ESPECIALLY IN THE AFTN.
LIGHT WIND FIELD AND VERY MOIST AIRMASS SUGGESTS BETTER POTENTIAL
FOR HEAVY RAIN WITH THESE STORMS THAN SVR WX. HIGHS FRIDAY SHOULD
RANGE FROM THE L70S NW WITH EARLIER FROPA... TO THE L80S SE.

CHC OF LINGERING SHOWERS/TSTMS FRI NGT AS FRONT CONTS TO SAG SLOWLY
SE THROUGH THE AREA. OVER THE WEEKEND... LEAD LOW IS EXPECTED TO
MOVE INTO THE OH VALLEY AND BE ABSORBED BY FOLLOWING CLOSED LOW
DROPPING SE FROM THE NRN PLAINS. THIS SHOULD RESULT IN
MOIST/EASTERLY/CYCLONIC FLOW ACROSS OUR AREA RESULTING IN MOSTLY
CLOUDY SKIES WITH A CHC OF SHOWERS AND CONSIDERABLY COOLER TEMPS.
MODELS DIFFER EARLY NEXT WEEK CONCERNING HOW LONG THIS SECOND CLOSED
LOW WILL CAUSE SHOWERY WX IN OUR AREA. FOR NOW STUCK WITH CURRENT
WX GRIDS FOR DAY6-7 IN LINE WITH LATEST ECMWF SUGGESTING A SLOWER
DEPARTURE OF THE SYSTEM.

.AVIATION.../06Z TAFS/
STNRY FRONT HAS SETTLED SW THIS EVE AND DRIER AIR IN LOW LEVELS VIA

POTENTIAL FOR FOG DIMINISHING OVERNIGHT AND HAVE REMOVED FROM TAFS.
SCT CU EXPECTED THROUGH THE PERIOD WITH SCT TSTMS PSBLY AGAIN THIS
