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 27, 7:39 PM EDT, 1 hour 38 minutes earlier. Its key messages:

  • Area of rain and embedded storms will move east over the next several hours. Additional storms are possible tonight, but confidence in the threat of severe storms is somewhat less than previously forecasted.
  • A period of gusty winds is expected in the wake of the rainfall with gusts of 40 to possibly 50 mph in some locations.
  • Temperatures trend cooler the remainder of the week with highs in the 50s.
  • Although a chance of rain returns Tuesday night into Wednesday, the bulk of the period Tuesday through this weekend appears to be dry.
  • Frost likely at times Wednesday night through Saturday night.

.DISCUSSION...
Issued at 203 PM EDT Mon Apr 27 2026

A large area of stratiform rain with embedded thunderstorms was
progressing east across western Indiana and eventually points to
the east with all areas seeing a 2 to 4 hour period of rainfall.
Severe weather is not expected with this area, as a organized,
elevated line of thunderstorms moves from central IL into
central IN. Behind the precipitation, HRRR and RAP continue to
advertise a period of gusty winds courtesy of an increasing
rise/fall pressure couplet from a developing wake low. Some
stronger gusts have been noted already in eastern IA and western
IL. A Wind Advisory was recently issued to handle this concern
through 00Z Tue, with some potential for an eastward (maybe
southward) expansion with time. The couplet seems to move east
and then transition NE, hence the area of the headlines for now.

Confidence in a threat for strong to severe storms is on the low
to medium side as CAMs are struggling to deal with the impacts
of the afternoon convection and subsidence with the wake low.
Not ready to dismiss the threat given the wind fields and
overall dynamics in place. The Enhanced and Moderate risk areas
remain well to our SW where the greatest concerns exist. A
conditional threat for convectively related damaging winds and
maybe a tornado or 2 may exist if storms can develop upstream
and move in. As a result, limited changes to the late
afternoon/early evening period. Continue to monitor later
updates. Some hydro concerns may exist into tonight if
additional convection does move in, but precip should remain
progressive enough to limit impacts.

Once we get past tonight, we trend cooler and for the most part
drier as more of a NW flow aloft sets up with a weak system
maybe bringing some showers to southern areas Tuesday night.
Concerns do still exist for frost/freeze headlines later this
week, but extended period left untouched for now with focus on
near term threats.

.AVIATION /00Z TAFS THROUGH 00Z WEDNESDAY/...
Issued at 731 PM EDT Mon Apr 27 2026

Sites begin VFR with gusty winds due to a wake low. The elevated
winds from the wake low will begin to decrease just after the
start of the TAF period. Another line of storms will approach
SBN around 02Z with TSRA threat through 05Z. These storms appear
to weaken as they approach SBN, but may maintain a marginally
severe wind threat for both SBN and FWA. Guidance isn't as
excited as previous runs with weaker storm threat between 02Z
and 06Z this evening. MVFR cigs and vsby are likely with any TS
but vsby improves after storms exit by 06Z. Low MVFR cigs remain
through daybreak before scattering out by early afternoon. A
return to VFR conditions for Tuesday afternoon.Southeast winds
become southerly with the -SHRA/-TSRA and then more westerly
Tuesday morning. SBN will likely be more west-northwesterly.
Winds begin to decrease by end of TAF period.
