What forecasters said that day

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

Area forecast discussion, Aug 8, 3:36 PM EDT, 3 hours 45 minutes before
Area Forecast Discussion
National Weather Service Northern Indiana
336 PM EDT Thu Aug 8 2019

.SYNOPSIS...
Issued at 335 PM EDT Thu Aug 8 2019

Outside of a small chance for a shower or thunderstorm south of
Route 30, dry weather will settle in for the next several days,
likely lasting through at least Sunday. The next meaningful chance
for showers and storms likely won't arrive until Monday or
Tuesday.

&&

.SHORT TERM...(This Evening through Friday)
Issued at 335 PM EDT Thu Aug 8 2019

Convection has been pretty scarce thus far with only development
being along remnant lake boundary extending from southern LaPorte
county to south of Van Wert/Lima. Secondary area of convection may
form just south of this feature where moisture is pooling and cold
front was edging towards. Either way, little more than 30 pops
are warranted with risk of severe very low (but not zero).

Everything will wind down this evening with clearing skies,
diminishing winds and falling temps/moisture with a nice day
shaping up for Friday as highs rebound into the upper 70s to lower
80s.

&&

.LONG TERM...(Friday Night through Thursday)
Issued at 335 PM EDT Thu Aug 8 2019

Most, if not all, of the weekend will be dry with high pressure
dominating the area. Models continue to bring a dampening
disturbance into the SW parts of the area on Sunday which could
bring a shower or storm. Blended models have been going back and
forth on pops and will keep out for the time being.

Better chance for showers/storms still appears to be Monday
afternoon into Tuesday when 1 or more waves move through the flow.
Blended models coming up with mid to high chc pops which works out
perfect at this point considering some timing/track differences.
No major temperature swings with highs generally in the 80s and
lows in the 60s.

&&

.AVIATION...(For the 18Z TAFS through 18Z Friday Afternoon)
Issued at 125 PM EDT Thu Aug 8 2019

A cold front is located northeast to southwest between SBN and
FWA. There is plenty of cumulus around, but t-storms are not
expected with the best instability south of FWA. Wind gusts are
expected to abate this evening.

&&
