The radar

The Northern Indiana radar (KIWX), 56 km from the middle of the area, began a volume at 06:20 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.

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 Apr 11, 1:50 AM EDT, 29 minutes earlier.

Area forecast discussion, Apr 11, 1:50 AM EDT, 29 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE NORTHERN INDIANA
150 AM EDT THU APR 11 2013

.UPDATE...
ISSUED AT 140 AM EDT THU APR 11 2013

MONITORING CONVECTIVE TRENDS OVER THE NEXT COUPLE OF HOURS AS 2
BOWING SEGMENTS EMBEDDED IN LEADING EDGE OF AREA OF RAIN WAS
ADVANCING TOWARDS BOTH SITES. AREA PUSHING THROUGH NW PARTS OF THE
AREA IS LOCATED IN STABLE BOUNDARY LAYER WITH NE FLOW TO LIKELY
WORK AGAINST POTENTIAL FOR MIX DOWN OF STRONG WIND FIELDS. AREAS
MOVING INTO SOUTHERN FORECAST AREA HAS MORE POTENTIAL ON NOSE OF
55 TO 60 KT LLJ AND NICE REFLECTIVITY SIGNATURE/NOT BUT ALIGNMENT
WITH MEAN MOVEMENT NOT THE MOST FAVORABLE. WATCH REMAINS IN EFFECT
THROUGH 3 AM EDT BUT WILL LIKELY BE CLEARED IN WAKE OF THIS
SYSTEM. OTHERWISE...PERIOD OF NEEDED RAINFALL WILL OCCUR THROUGH
THE REMAINDER OF THE NIGHT...ESPECIALLY NW. 3 HR PRESSURE FALL OF
AROUND 2 MB AND RISE OF ABOUT 3 MB ASSOCIATED WITH THE SOUTHERN
LINE HAS BEEN STIRRING UP WINDS BEHIND THE PRECIP. WILL NEED TO
MONITOR THIS BUT NO SIG CHANGES FOR NOW.

&&

.SHORT TERM...(THIS EVENING THROUGH THURSDAY)
ISSUED AT 409 PM EDT WED APR 10 2013

ABBREVIATED DISCUSSION GIVEN ONGOING SEVERE WEATHER.
IMPRESSIVE THERMAL GRADIENT ACROSS THE CWA TODAY WITH TEMPS IN LOW
40S FAR NORTH AND UPPER 70S SOUTH. QUASI STATIONARY BOUNDARY AND
SEVERAL MESOSCALE BOUNDARIES IN ADDITION TO INLAND LAKE BREEZE
PROVING DIFFICULT SCENARIO WITH RESPECT TO ACCURATE HOURLY GRIDS AND
TRENDS. NO SHORT TERM GUIDANCE IS HANDLING SITUATION WITH TRENDS
SHOWING WARMING ACROSS THE CWA INTO EARLY EVENING. HAVE MANUALLY
ADJUSTED HOURLY GRIDS WITH CONSTANT UPDATES AND THIS TREND TO
CONTINUE THROUGH THE EVENING. RADAR MOSAIC SHOWS SEVERAL ROUNDS OF
SHOWERS AND THUNDERSTORMS WHICH WILL MOVE NORTHEAST OVER THE AREA
THIS EVENING. HI RES GUIDANCE SHOWS BREAKS TO SOUTHWEST FILLING IN
FOLLOWED BY MORE WIDESPREAD RAIN OVERNIGHT AS MAIN AREA OF LIFT AND
THETA E MOVES IN. COLD FRONT TO FINALLY PUSH EAST ON THURSDAY WITH
RAIN DIMINISHING FROM WEST TO EAST AND COLDER TEMPS MOVING IN.
SOUTHEAST TO POSSIBLY GET INTO WARM SECTOR AGAIN BUT TRICKY
DEPENDING ON WHERE APPROACHING SFC WAVES TRACKS. BLENDED NAM12 AND
SREF FOR TEMPS AND WINDS THROUGH THE SHORT TERM.

&&

.LONG TERM...(THURSDAY NIGHT THROUGH WEDNESDAY)
ISSUED AT 409 PM EDT WED APR 10 2013

DRY SLOT WILL CONTINUE TO PUSH EASTWARD ACROSS FAR NORTHEAST INDIANA
AND NORTHWEST OHIO THURSDAY EVENING EVENTUALLY TAKING FOCUS OF
ADDITIONAL RAIN SHOWERS EASTWARD. TROWAL FEATURE MAY PROLONG RAIN
SHOWERS THROUGH THE NIGHT ACROSS SOUTHERN LOWER MICHIGAN BUT LIKELY
DIMINISHING IN COVERAGE. RENEWED DPVA WITH SMALLER SCALE VORTS
ROTATING THROUGH GREAT LAKES AND RISING INVERSION HEIGHTS WITH
STRENGTHENING LOW LEVEL CAA SHOULD PROVIDE ENOUGH
FORCING/INSTABILITY FOR SCATTERED SHOWERS TO REDEVELOP...MAINLY
ACROSS THE NORTHERN HALF. PRECIP MAY END AS SCATTERED LIGHT RAIN OR
SNOW SHOWERS ACROSS FAR NORTH FRIDAY EVENING. UPPER FLOW TO
DEAMPLIFY FOR THE EARLY PART OF THE WEEKEND WHICH WILL ALLOW FOR
SHORT RESIDENCE TIME OF THERMAL TROUGH. STRONG LOW LEVEL WAA TO
COMMENCE SATURDAY NIGHT AND WILL KEEP CHANCE RAIN SHOWER POPS INTACT
FOR SUNDAY WITH MODERATING TEMPERATURES BACK INTO THE MID TO UPPER
50S. MEDIUM RANGE MODELS ARE IN FAIRLY GOOD AGREEMENT IN LONGWAVE
WESTERN CONUS TROUGH-EASTERN CONUS RIDGE DEVELOPING WHICH WOULD KEEP
LOCAL AREA IN ACTIVE SOUTHWEST FLOW PATTERN. THIS PATTERN WOULD ALSO
BE CONDUCIVE FOR ANOTHER LOW LEVEL BAROCLINIC ZONE SPRAWLING OUT
ACROSS THE AREA WITH POTENTIAL LARGE SOUTH TO NORTH TEMPERATURE
GRADIENTS ONCE AGAIN. HAVE GENERALLY FOLLOWED MODEL CONSENSUS FOR
HIGHS IN THE UPPER 50S TO MID 60S FOR MON-WED...ALTHOUGH ONCE UPPER
PATTERN AND SMALLER SCALE WAVES BECOME BETTER RESOLVED...A TIGHTER
GRADIENT IN TEMPS MAY BE NEEDED. HAVE ALSO MAINTAINED BROADBRUSH
CHANCE RAIN SHOWER POPS THROUGH EARLY NEXT WEEK AND ALSO MAY NEED TO
ASSESS NEED FOR TS INCLUSION IN LATER FORECASTS DEPENDING ON
PLACEMENT OF BAROCLINIC ZONE.

&&

.AVIATION...(FOR THE 06Z TAFS THROUGH 06Z THURSDAY NIGHT)
ISSUED AT 140 AM EDT THU APR 11 2013

MAIN FOCUS OF TAFS WILL BE NEXT 6 TO 9 HOURS WITH FEW
CHANGES BEYOND THAT PERIOD. FRONTAL ZONE WAS WORKING NORTH ACROSS
THE AREA IN RESPONSE TO 55 KT SSW LLJ NOTED ON KIND VWP. AN AREA OF
SHOWERS AND THUNDERSTORMS HAS NEARLY CLEARED KFWA BUT WILL AFFECT
KSBN FOR THE NEXT COUPLE OF HOURS. TO FURTHER COMPLICATE
TAFS...LARGE AREA OF RAIN AND STORMS WAS ENTERING WESTERN PORTIONS
OF INDIANA WITH A LINE OF INCREASED WIND POTENTIAL. STABLE BOUNDARY
LAYER MAY MAKE IT DIFFICULT TO MIX DOWN STRONGER WINDS JUST OFF THE
SFC BUT LOCALLY HIGH WIND GUSTS WILL BE POSSIBLE AT KSBN IN A FEW
HOURS. OTHERWISE...NO BRAINER ON EXTENDED PERIOD OF IFR CIGS AND
OCCASIONAL IFR VSBYS IN HEAVIER SHOWERS AND STORMS THROUGH AT LEAST
8Z...ASSUMING NO FURTHER DEVELOPMENT. AS NOTED AT KFWA...THE CURRENT
LULL WILL BE SHORT LIVED AS SOUTHERN EXTENT OF ABOVE MENTIONED LINE
WITH QUICKLY MOVE TOWARDS THE AIRPORT BETWEEN 630Z AND 730Z. SIMILAR
WIND CONCERNS COULD EXIST WITH THIS AS WELL FOLLOWED BY AN EXTENDED
PERIOD OF RAIN/EMBEDDED STORMS THROUGH 9 OR 10Z. WILL NOT INCLUDE
HIGHER WIND GUSTS ATTM IN THE TAFS FOR EITHER SITE.

UPPER LOW WILL STILL BE MAKING SLOW PROGRESS EASTWARD THROUGH THE
DAY THURS WITH ADDITIONAL CHANCES FOR PRECIP THROUGH THE DAY. TRENDS
WOULD SUGGEST BEST FORCING MAY BE GONE BY LATE AFTERNOON SO WILL TRY
TO END PRECIP. AGAIN...WITH FOCUS ON EARLIER PERIOD ADDITIONAL
REFINEMENTS TO LATER PERIODS WILL BE NEEDED.
