The radar

The Northern Indiana radar (KIWX), 100 km from the middle of the area, began a volume at 06:16 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, 6.2 hours before the alert went out and 152 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.

What forecasters said that day

The local office's own words before this severe thunderstorm warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Northern Indiana wrote its last area forecast discussion before this severe thunderstorm warning went out at Jul 20, 1:52 AM EDT, 21 minutes earlier.

Area forecast discussion, Jul 20, 1:52 AM EDT, 21 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTHERN INDIANA
152 AM EDT SAT JUL 20 2013

.SYNOPSIS...
ISSUED AT 146 PM EDT FRI JUL 19 2013

SOUTHWEST WINDS IN ADVANCE OF A COLD FRONT WILL KEEP THE HOT AND
HUMID CONDITIONS IN PLACE ACROSS THE REGION THROUGH THIS EVENING.
THE APPROACHING COLD FRONT WILL INTERACT WITH THE WARM AND MOIST
AIR MASS TO PRODUCE A GOOD CHANCE OF SHOWERS AND THUNDERSTORMS FROM
THIS AFTERNOON THROUGH TONIGHT. SCATTERED THUNDERSTORMS MAY
LINGER INTO SATURDAY BEFORE DRIER AIR BUILDS INTO THE REGION
BEHIND THE FRONT BY SATURDAY NIGHT.

&&

.UPDATE...
ISSUED AT 703 PM EDT FRI JUL 19 2013

CLUSTER OF TSTMS ALONG PRE-FRONTAL TROF OVER SE MI SHOULD STAY TO
THE NE OF OUR CWA. A SECOND PRE-FRONTAL TROF APPEARS TO BE MOVG EAST
ACROSS LAKE MICHIGAN ATTM... BUT CAPE HAS BEEN DECREASING AHEAD
OF THIS FEATURE SO DOUBTFUL IF TSTMS WILL DEVELOP ALONG IT. TSTMS
HAVE BEEN DEVELOPING ALONG THE CDFNT FROM NRN LWR MI SW ACROSS SRN
WI INTO ERN IA AND CAPE INCREASING OVER NRN IL AHEAD OF THE
FRONT. LATEST HIGH RES MODELS CONT TO SUGGEST TSTMS WILL DEVELOP
INTO A LINE AND CROSS OUR AREA TONIGHT. THIS SCENARIO SEEMS
REASONABLE BUT MODELS APPEAR A BIT FAST ON EVOLUTION. WILL UPDATE
HOURLY WX GRIDS SOON TO DELAY LIKELY POPS IN THE NW PORTION OF THE
CWA UNTIL ABOUT 03Z... WITH CONTINUATION OF EARLIER TREND OF
INCRSG THE POPS SEWD WITH A LINE EXPECTED TO DVLP OVERNIGHT.

HEAT/WIND ON DOWNWARD TREND AS EXPECTED AND NPW/MWW/CFW HEADLINES
WILL BE ALLOWED TO EXPIRE AS SCHEDULED AT 00Z.

&&

.SHORT TERM...(THIS EVENING THROUGH SATURDAY)
ISSUED AT 429 PM EDT FRI JUL 19 2013

CONTINUING TO MONITOR SEVERE WEATHER POTENTIAL LATE THIS
AFTERNOON THROUGH THE EVENING AS A WARM UNSTABLE AIR MASS IN PLACE
ACROSS THE REGION YIELDING ML CAPES AA 2500 J/KG. MODELS CONTINUE
TO INDICATE CONVECTION FIRING ALONG PRUE FRONTAL TR OF CURRENTLY
FROM CENTRAL IOWA NORTHEAST TO GREEN BAY AND UPPER MI AND MOVE
INTO THE AREA LATE THIS AFTERNOON INTO EARLY EVENING. STRONG COLD
FRONT W/ A POTENT UPPER TR OF WITH SWING SOUTHEAST AND MERGE WITH
THIS PRUE FRONT TR OF/WIND SHIFT...AND MOVE SOUTHEAST ACROSS THE
AREA THROUGH SATURDAY MORNING.

HI RES MODELS CONTINUE TO STRUGGLE WITH ONGOING CONVECTION AND
SUBSEQUENT SOLUTIONS. ANY STORMS ACROSS THE AREA EXPECTED TO
STRUGGLE AS BETTER FORCING REMAINS NORTHWEST OF THE AREA. PRECIP
CHANCES EXPECTED TO INCREASE ACROSS THE AREA AS THE FRONT
APPROACHES...WITH EFFECTIVE BULK SHEAR VALUES OF 25-30 KTS AND
DECENT SFC CONVERGENCE. HOWEVER...TIMING IS BECOMING UNFAVORABLE
WITH THE COINCIDENCE OF BEST SHEAR AND INSTABILITY...AS LOSS OF
DIURNAL HEATING EXPECTED TO STABILIZE THE ATMOSPHERE BY THE TIME THE
BEST FORCING/SHEAR ARRIVES THIS EVENING. CONTINUED TO TREND POPS
INCREASING ACROSS NORTHWESTERN AREAS THROUGH 00Z. RIGHT NOW...BEST
CHANCE FOR SEVERE STORMS WILL BE FROM THE 00Z-04Z TIME FRAME ACROSS
NORTHERN AREAS...BUT ONLY CONDITIONAL UPON ADEQUATE FORCING/SHEAR
COINCIDING WITH WANING...ALBEIT APPRECIABLE INSTABILITY. MAIN
THREATS WILL INCLUDE DAMAGING WINDS...WITH MODEST LOW/MID LEVEL FLOW
ACROSS NORTHERN AREAS...INCREASING MID LVL LAPSE RATES AND DC APE
VALUES FROM 800-1200.

EXPECT COVERAGE OF STORMS TO BECOME MORE SCATTERED THROUGH THE
OVERNIGHT AS THE FRONT MOVES SOUTH ACROSS THE AREA WITH STABILIZING
CONDITIONS. REFLECTED THIS GRADUAL LOWERING TO HIGH CHANCE POPS
THROUGH THE OVERNIGHT. FRONT WILL SLIP INTO THE SOUTHERN PART OF THE
AREA BY SATURDAY MORNING. CONTINUED WITH CHANCE POPS ACROSS FAR
SOUTHERN AREAS AS MODESTLY UNSTABLE CONDITIONS SHOULD DEVELOP ALONG
AND SOUTH OF THE FRONT THROUGH THE DAY. NO MAJOR CHANGES TO
TEMPERATURES TONIGHT OR SATURDAY.

&&

.LONG TERM...(SATURDAY NIGHT THROUGH FRIDAY)
ISSUED AT 429 PM EDT FRI JUL 19 2013

LONG WAVE PATTERN CONTINUES THE WEAKENING H5 RIDGE ACROSS THE
SOUTHEAST US AND AMPLIFYING OVER THE FOUR-CORNERS/SOUTHERN PLAINS
THROUGH THE LONG TERM.

WESTERLY FLOW WITH A SERIES OF EMBEDDED SHORTWAVES WILL HELP TO
REINFORCE BROAD TR OF OVER THE GREAT LAKES/EASTERN THIRD OF THE US
AND SHUNT MOISTURE AND INSTABILITY SOUTH AND EAST. WHILE INSTABILITY
WILL BE LESSENED IN THE EXTENDED...CANNOT RULE OUT IS OLD TO
SCATTERED CONVECTION WITH EACH TR OF/SHORTWAVE PASSAGE.

TIMING OF THESE FEATURES IS PROBLEMATIC. TEMPORAL AND SPATIAL
RESOLUTIONS DO NOT AFFORD ANY CONFIDENCE FOR TIMING THE
FORMATION/DURATION/INTENSITY OF CONVECTION THIS FAR OUT.

THE MOST NOTABLE CHANGE IN THE EXTENDED PERIOD IS THE SIGNIFICANTLY
LOWER TEMPERATURES. BY MID-WEEK SHOULD SEE TEMPERATURES AT OR BELOW
NORMAL FOR THIS TIME OF THE YEAR...ESPECIALLY DURING THE DAYTIME.

COOLER AIR WILL REMAIN IN PLACE THROUGH THE EXTENDED PERIOD.

ONLY EXPECT TO MAKE MINOR ADJUSTMENTS AND TWEAKS TO THE EXISTING
FORECAST GRIDS.

&&

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z SATURDAY NIGHT)
ISSUED AT 143 AM EDT SAT JUL 20 2013

SCATTERED SHOWERS AND THUNDERSTORMS LIKELY TO CONTINUE OVER THE
NEXT SEVERAL HOURS PARTICULARLY ACROSS FAR NORTH CENTRAL/NORTHEAST
INDIANA WHERE STRONGER FORCING PERSISTS. BEST LOW LEVEL MOISTURE
POOLING HAS OCCURRED IN ADVANCE OF THE COLD FRONT WITH MOST OF
CONVECTION ACROSS SOUTHERN LOWER MICHIGAN REMAINING AHEAD OF THE
FRONT. WITH SFC FRONT STILL WEST OF KSBN...POTENTIAL OF ADDITIONAL
ISOLATED TO SCATTERED SHOWERS AND THUNDERSTORMS PERSISTS THROUGH
ABOUT 09Z OR SO...BUT WITH COVERAGE EXPECTED TO BE LIMITED HAVE
CONFINED THUNDER MENTION TO VCTS. HAVE ALSO MAINTAINED 08Z-11Z
VCTS MENTION AT KFWA WITH MID/UPPER FORCING BECOME MORE
QUESTIONABLE WITH SOUTHWARD EXTENT AS SFC FRONT APPROACHES. FOCUS
FOR CONVECTION ON SATURDAY SHOULD REMAIN SOUTH OF TERMINALS AND
HAVE KEPT TAFS DRY THROUGH THE REMAINDER OF THE PERIOD WITH WINDS
BECOME NORTHWEST BEHIND THE FRONT.
